Airline Aircrafts

  1. 1. Air Force One is the official air traffic control call sign of a United States Air Force aircraft carrying the President of the United States. In common parlance the term refers to those Air Force aircraft specifically designed, built, and used for the purpose of transporting the president. The Presidential aircraft is a prominent symbol of the American presidency and its power. The idea of designating specific military aircraft to transport the President arose in 1943, when officials of the United States Army Air Forces – the predecessor to the U.S. Air Force – became concerned with relying on commercial airlines to transport the President. A C-87 Liberator Express was reconfigured for use as a presidential transport; however, it was rejected by the Secret Service amid concerns over the aircraft's safety record. A C-54 Skymaster was then converted for presidential use; this aircraft, dubbed theSacred Cow, transported President Franklin D. Roosevelt to the Yalta Conference in February 1945, and was subsequently used for another two years by President Harry S. Truman. The "Air Force One" call sign was created after a 1953 incident during which a flight carrying President Dwight D. Eisenhowerentered the same airspace as a commercial airline flight using the same call sign. Several aircraft have been used as Air Force One since the creation of the presidential fleet, including two Boeing 707s introduced in the 1960s and 1970s, respectively; since 1990, the presidential fleet has consisted of two Boeing VC-25As – specifically configured, highly customized Boeing 747-200B series aircraft. The Air Force is looking into replacing the two VC-25 aircraft with three replacement aircraft beginning in 2017.
  2. 2. HISTORY On 11 October 1910, Theodore Roosevelt became the first U.S. President to fly in an aircraft, although at the time of the flight in an early Wright Flyer from Kinloch Field (near St. Louis, Missouri), he was no longer in office, having been succeeded by William Howard Taft. The record-making occasion was a brief overflight of the crowd at a country fair but was nonetheless the beginning of presidential air travel. Prior to World War II, overseas and cross-country presidential travel was rare. Lack of wireless telecommunication and quick transportation made long-distance travel impractical; as it took much time and isolated the president from events in Washington, D.C. Railroads were a safer and more reliable option if the President needed to travel to distant states. By the late 1930s, with the arrival of aircraft such as the Douglas DC-3, increasing numbers of the U.S. public saw passenger air travel as a reasonable mode of transportation. All-metal aircraft, more reliable engines, and new radio aids to navigation had made commercial airline travel safer and more convenient. Life insurance companies even began to offer airline pilots insurance policies, albeit at extravagant rates, and many commercial travelers and government officials began using the airlines in preference to rail travel, especially for longer trips. Franklin D. Roosevelt was the first president to fly in an aircraft while in office. The first aircraft obtained specifically for presidential travel was a Douglas Dolphin amphibian delivered in 1933 which was designated RD-2 by the US Navy and based at the Naval base at Anacostia D.C. The Dolphin was modified with a luxury upholstery for four passengers and a small separate sleeping compartment. The aircraft remained in service as a presidential transport from 1933 until 1939. There are no reports as to whether the president ever flew in the aircraft though. During World War II, Roosevelt traveled on the Dixie Clipper, a Pan Am-crewed Boeing 314 flying boat to the 1943 Casablanca Conference, in Morocco, a flight that covered 5,500 miles (in three "legs"). The threat from the German submarines throughout
  3. 3. the Battle of the Atlantic made air travel the preferred method of VIP transatlantic transportation. Concerned about relying upon commercial airlines to transport the president, USAAF leaders ordered the conversion of a military aircraft to accommodate the special needs of the Commander in Chief. The first dedicated aircraft proposed for presidential use was a C-87AVIP transport aircraft. This aircraft, number 41-24159, was re-modified in 1943 for use as a presidential VIP transport, the Guess Where II, intended to carry President Franklin D. Roosevelt on international trips. Had it been accepted, it would have been the first aircraft to be used in presidential service, in effect the first Air Force One. However, after a review of the C-87's highly controversial safety record in service, the Secret Service flatly refused to approve the Guess Where II for presidential carriage. Also, the C-87 was a derivative of the Consolidated B-24 Liberator bomber, so it presented strong offensive impressions to both enemy fighter aircraft as well as foreign dignitaries being visited, an issue not present with airframes that were used purely for transport. The Guess Where II was then used to transport senior members of the Roosevelt administration on various trips. In March 1944, it transported Eleanor Roosevelt on a goodwill tour of several Latin American countries. The C-87 was scrapped in 1945 Historically, several U.S. presidents have flown on Boeing aircraft. In 1943, President Franklin D. Roosevelt flew to Casablanca aboard a Boeing model 314 Clipper. In 1962, Boeing introduced U.S. presidents to modern jet transportation with the introduction of the Boeing model 707320B. In all, seven presidents were served by the 707-320B.
  4. 4. Today, the chief executive flies aboard a specially configured 747-200B, the newest and largest presidential airplane. Its capabilities include: Longer range for presidential travel Aerial refueling Self-sufficiency at airports around the world The "flying Oval Office" has 4,000 square feet of interior floor space. Among its accommodations are: Conference/dining room Quarters for the president and the first lady An office area for senior staff members Another office that converts into a medical facility when necessary Work and rest areas for the presidential staff, media representatives and Air Force crews Two galleys that can provide 100 meals at one sitting Multi-frequency radios for air-to-air, air-to-ground and satellite communications Principal differences between Air Force One and the standard Boeing 747 include state-of-the-art navigation, electronic and communications equipment; its interior configuration and furnishings; self-contained baggage loader; and front and aft airstairs.
  5. 5. SINGAPORE AIRLINE History Singapore Airlines began with the incorporation of Malayan Airways Limited (MAL) on 1 May 1947, by the Ocean Steamship Company of Liverpool, the Straits Steamship Company of Singapore and Imperial Airways. The airline's first flight was a chartered flight from the British Straits Settlement of Singapore to Kuala Lumpur on 2 April 1947 using an Airspeed Consul twin-engined aircraft. Regular weekly scheduled flights quickly followed from Singapore to Kuala Lumpur, Ipoh and Penang from 1 May 1947 with the same aircraft type. The airline continued to expand during the rest of the 1940s and 1950s, as other British Commonwealth airlines (such as BOAC and Qantas Empire Airways) provided technical assistance, as well as assistance in joining IATA.[citation needed] By 1955, Malayan Airways' fleet had grown to include a large number of Douglas DC-3s, and went public in 1957. Other aircraft operated in the first two decades included the Douglas DC-4 Skymaster, the Vickers Viscount, the Lockheed 1049 Super Constellation, the Bristol Britannia, the de Havilland Comet 4 and the Fokker F27. When Malaya, Singapore, Sabah and Sarawak formed the Federation of Malaysia in 1963, the airline's name was changed, from
  6. 6. "Malayan Airways" to "Malaysian Airways". MAL also took over Borneo Airways. In 1966, following Singapore's separation from the federation, the airline's name was changed again, to Malaysia-Singapore Airlines (MSA). The next year saw a rapid expansion in the airline's fleet and route, including the purchase of MSA's first Boeing aircraft, the Boeing 707s, as well the completion of a new high-rise headquarters in Singapore. Boeing 737s were added to the fleet soon after. Singapore Airlines operates a hub at Changi Airport and has a strong presence in the Southeast Asia, East Asia, South Asia, and "Kangaroo Route" markets. Singapore Airlines was the launch customer of Airbus A380, currently the world's largest passenger aircraft. SIA has diversified airline-related businesses, such as aircraft handling and engineering. Its wholly owned subsidiary, SilkAir, manages regional flights to secondary cities with smaller capacity requirements. Singapore Air offers two longest non-stop commercial flights aboard the Airbus A340-500 which fly to Newark and Los Angeles from Singapore. Singapore Airline has the London Heathrow Airport and the Sydney Airport as its focus cities. It offers its frequent flyer program under the KrisFlyer Club for passengers availing Singapore Air flights on a frequent basis.

  9. 9. In-flight services Cabins Singapore Airlines offers four classes of service – suites, first class, business class and economy class. Major upgrades to its cabin and in-flight service were announced on 17 October 2006, the first major overhaul in over eight years and costing the airline approximately S$570 million. Initially planned for its Airbus A380-800's introduction into service in 2006, and subsequently on the Boeing 777-300ER, the postponement of the first A380-800 delivery meant it had to be introduced with the launch of the first Boeing 777-300ER with the airline on 5 December 2006 between Singapore and Paris. On July 9, 2013, Singapore Airlines, in collaboration with two design firms, James Park Associates and DesignworksUSA, unveiled the next generation of cabin products for First, Business, and Economy class, which will enter service onboard new Boeing 777-300ERs and Airbus A350s. London will be the first city served with the new product in September. Singapore Airlines Suites Singapore Airlines Suites is a class available only on the Airbus A380. The product was designed by French luxury yacht interior designer Jean-Jacques Coste and consists of separate compartments with walls and doors 1.5 m high. The leather seat, upholstered by Poltrona Frau of Italy, is 35 in (89 cm) wide (with armrests up and 23 in (58 cm) wide when armrests are down) and a 23 in (58 cm) LCD TV screen is mounted on the front wall. The 78 in (200 cm) bed is separate from the seat and folds out from the back wall, with several other components of the suite lowering to accommodate the mattress. Windows are built into the doors and blinds offer privacy. Suites located in the center can form a double bed after the privacy blinds between them are retracted into special compartments between the beds and in the frame of the partition.
  10. 10. Boeing 777-300ER First Class First class There are three variations of the first class cabin, although the Singapore Airlines Suites class is designated by Singapore Airlines as a "Class Beyond First" and uses a different fare code (R) (see above). Introduced on 17 October 2006, the "New" First Class is offered only on Boeing 777300 and Boeing 777-300ER aircraft. Designed by James Park Associates, it features a 35 in (89 cm) wide seat upholstered with leather and mahogany and a 23 in (58 cm) LCD screen. The seats fold out into a flat bed and are arranged in a 1-2-1 configuration. The First Class in 3-class-configured Boeing 777-200 features sleeper seats that are 21 in (53 cm) wide in a 2-2-2 configuration. It has a 10.4 inch display screen for IFE with AVOD technology. The first class product will be retired shortly in the third quarter of 2013, along with the withdrawal of all 3-class B777-200, awaiting on the delivery of the 24th A330 to Singapore Airlines and subject to regulatory approval. The latest first class seat was introduced on 9 July 2013. Features include a 24-inch in-flight entertainment screen with video-touch screen handsets, adjustable in-seat lighting, and passenger control unit, inside a fixed-shell cabin with an 35 in (89 cm) wide seat, foldable into an 80 in (203 cm) bed. Boeing 777-300ER Business Class Business class Formerly known as Raffles Class until 2006, the Business Class on the Airbus A380, Airbus A340-500, Boeing 777-300ER, a fully flat bed is available in a 1-2-1 configuration featuring 30 in (76 cm) of seat width. These seats are forward-facing, in contrast to the herring-bone configuration used by several other airlines offering flat
  11. 11. beds in business class. The leather seats feature a 15.4 in (39.1 cm) diagonal screen size personal television, in-seat power supply and 2 USB ports. This seat is also being progressively introduced on Boeing 777-200ER aircraft. The new Singapore Airlines business class (usually operating on the A380, A340 and 777-300ER aircraft) was voted the world's best business class by Skytrax in 2011. On eight Airbus A380 aircraft, the first of which entered service in October 2011, Singapore Airlines extended the business class cabin to run the entire length of the upper deck, compared to the original configuration which shares the upper deck between 16 rows of business class and 11 rows of economy at the rear. New Regional Business Class is available on Airbus A330-300, Boeing 777-300 and select Boeing 777-200 aircraft, configured in 2-2-2 layout and with iPod connectivity. The Business Class seat is lie-flat at an 8-degree incline, featuring Krisworld on a 15.4 inch screen. SpaceBed seats are being progressively phased out and currently are available on three Boeing 777-200ER aircraft in a 2-2-2 configuration. The SpaceBed seats are 27 in (69 cm) wide and 72 in (183 cm) long and convert to an angled flat bed. They have a retractable 10.4 in (26.4 cm) personal television, and are being phased out in favor of New Business Class seats. Traditional Ultimo business class seats, which do not convert into beds, are offered on 7 Boeing 777-200 aircraft in a 2-3-2 configuration with an 8.4 inch screen. A new design of Business Class seat was unveiled on July 9, 2013. Features include power socket and ports all in one panel, stowage beside the seat, two new seating positions and a 18-inch in-flight entertainment screen. The seat has a recline of 132 degrees and can be folded into an 78 in (198.1 cm) length bed.
  12. 12. Economy Class Airbus A380-800 Economy Class The old economy class seats in all 7 unrefitted Boeing 777-200s and 3 unrefitted Boeing 777-200ERs have VGA 6.1 inch personal television screens, footrests, adjustable headrests with side-flap "ears" and adjustable seat reclines. Baby bassinets are available at some bulkheads. These older Economy Class seats with the Wisemen 3000 AVOD system were introduced with the Boeing 777-200ER in 1997, for use alongside the existing Economy Class seats with the non-AVOD KrisWorld (at that time on board the airline's Boeing 747-400s and A340-300s, having been introduced in 1995) and the older-generation early 1990s seats without KrisWorld (at that time on board the airline's A310-200s and A310-300s). After the first Boeing 777-200ER had been delivered on 5 May 1997, the updated Economy Class seat was installed in all subsequent aircraft deliveries (including newer -SP* series Boeing 747-400s), as well as in refitted existing Boeing 747-400s in late 1997 and early 1998. The new Economy class seats on the Boeing 777-300ER, Airbus A380-800, and Airbus A330-300 are 19.5 in (50 cm) wide, have in-seat power and have a 10.6in personal television screen which has a non-intrusive reading light under it, which can be used by folding the screen outwards. These are configured 3-4-3 on the lower deck of the Airbus A380, 3-3-3 on the Boeing 777, and 2-4-2 on the Airbus A330, as well as the upper deck of the Airbus A380.[116] Other features include an independent cup holder (separate from the fold-out table), a USB port, and a power socket, as well as an iPod port exclusively on board the Airbus A330. Singapore Airlines introduced a similar design on board the Boeing 777 aircraft through their ongoing cabin retrofit program. The Boeing 777-300 is the first model to undergo refit and has introduced the product on the Singapore – Sydney route on 22 July 2009. Equipped with bigger 9-inch screens and AVOD in each seat. The seats are installed onboard 11 B777-200s, 7 B777-300s and 8 B777-200ERs.
  13. 13. A redesign of the Economy Class seat was unveiled on July 9, 2013. Features include increased legroom, an adjustable headrest, and an 11.1 inch-touch screen in-flight entertainment system which also controllable with a video touch-screen handset.

In-flight entertainment (IFE) refers to the entertainment available to aircraft passengers during a flight. In 1936, the airship Hindenburg offered passengers a piano, lounge, dining room, smoking room, and bar during the 2½ day flight between Europe and America. After the Second World War, IFE was delivered in the form of food and drink services, along with an occasional projector movie during lengthy flights. In
  19. 19. 1985 the first personal audio player was offered to passengers, along with noise cancelling headphones in 1989 During the 1990s the demand for better IFE was a major factor in the design of aircraft cabins. Before then, the most a passenger could expect was a movie projected on a screen at the front of a cabin, which could be heard via a headphone socket at his or her seat. The largest manufacturers of IFE systems are Panasonic Avionics Corporation, Thales Group, Zodiac, Lumexis, Gogo, On Air, Row 44Rockwell Collins, and LiveTV Design issues for IFE include system safety, cost efficiency, software reliability, hardware maintenance, and user compatibility. The in-flight entertainment onboard airlines is frequently managed by content service providers. Airport check-in procedure uses service counters found at commercial airports handling commercial air travel. The check-in is normally handled by an airline itself or a handling agent working on behalf of an airline. Passengers usually hand over any baggage that they do not wish or are not allowed to carry on to the aircraft's cabin and receive a boarding pass before they can proceed to board their aircraft. Check-in is usually the first procedure for a passenger when arriving at an airport, as airline regulations require passengers to check in by certain times prior to the departure of a flight. This duration spans from 15 minutes to 4 hours depending on the destination and airline. During this process, the passenger has the ability to ask for special accommodations such as seating preferences, inquire about flight or destination information, make changes to reservations, accumulate frequent flyer program miles, or pay for upgrades. The airline check-in's main function, however, is to accept luggage that is to go in the aircraft's cargo hold and issue boarding passes. Check-in options and procedures vary per airline with some airlines allowing certain restrictions other airlines have in place, and occasionally the same airline at two
  20. 20. separate airports may have different check-in procedures. Such differences are usually not noted by the average passenger and occasionally lead to service interruptions when one carrier refuses to abide by the procedure that another carrier normally would be willing to do. In-town check-in service is a service offered by some cities such as Abu Dhabi, Seoul, Hong Kong, Delhi, Kuala Lumpur, Stockholm,Vienna and Taipei, where passengers may check in luggage in designated places within the city but outside the airport. This reduces check-in time and queuing at the airport. A propeller is a type of fan that transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and a fluid (such as air or water) is accelerated behind the blade. Propeller dynamics can be modelled by both Bernoulli's principle and Newton's third law. A marine propeller is sometimes colloquially known as a screw propeller or screw. Aircraft propellers The twisted airfoil (aerofoil) shape of modern aircraft propellers was pioneered by the Wright brothers. While some earlier engineers had attempted to model air propellers on marine propellers, they realized that a propeller is essentially the same as a wing, and were able to use data from their earlier wind tunnel experiments on wings. They also introduced a twist along the length of the blades. This was necessary to ensure the angle of attack of the blades was kept relatively constant along their length.[13] Their original propeller blades were only about 5% less efficient than the modern equivalent, some 100 years later. The understanding of low speed propeller
  21. 21. aerodynamics was fairly complete by the 1920s, but later requirements to handle more power in smaller diameter have made the problem more complex. Alberto Santos Dumont, another early pioneer, applied the knowledge he gained from experiences with airships to make a propeller with a steel shaft and aluminium blades for his 14 bis biplane. Some of his designs used a bent aluminium sheet for blades, thus creating an airfoil shape. They were heavily undercambered, and this plus the absence of lengthwise twist made them less efficient than the Wright propellers. Even so, this was perhaps the first use of aluminium in the construction of an airscrew. History In the second half of the nineteenth century, several theories were developed. The momentum theory or disk actuator theory—a theory describing a mathematical model of an ideal propeller—was developed by W.J.M. Rankine (1865), Alfred George Greenhill (1888) and R.E. Froude (1889). The propeller is modelled as an infinitely thin disc, inducing a constant velocity along the axis of rotation. This disc creates a flow around the propeller. Under certain mathematical premises of the fluid, there can be extracted a mathematical connection between power, radius of the propeller,torque and induced velocity. Friction is not included. The blade element theory (BET) is a mathematical process originally designed by William Froude (1878), David W. Taylor (1893) and Stefan Drzewiecki to determine the behaviour of propellers. It involves breaking an airfoil down into several small parts then determining the forces on them. These forces are then converted into accelerations, which can be integrated into velocities and positions. Theory of operation A propeller is the most common propulsor on ships, imparting momentum to a fluid which causes a force to act on the ship. The ideal efficiency of any size propeller (free-tip) is that of an actuator disc in an ideal fluid. An actual marine propeller is made up of sections of helicoidal surfaces which act together
  22. 22. 'screwing' through the water (hence the common reference to marine propellers as "screws"). Three, four, or five blades are most common in marine propellers, although designs which are intended to operate at reduced noise will have more blades. The blades are attached to a boss (hub), which should be as small as the needs of strength allow - with fixed pitch propellers the blades and boss are usually a single casting. An alternative design is the controllable pitch propeller (CPP, or CRP for controllablereversible pitch), where the blades are rotatednormally to the drive shaft by additional machinery - usually hydraulics - at the hub and control linkages running down the shaft. This allows the drive machinery to operate at a constant speed while the propeller loading is changed to match operating conditions. It also eliminates the need for a reversing gear and allows for more rapid change to thrust, as the revolutions are constant. This type of propeller is most common on ships such as tugs where there can be enormous differences in propeller loading when towing compared to running free, a change which could cause conventional propellers to lock up as insufficient torque is generated. The downsides of a CPP/CRP include: the large hub which decreases the torque required to cause cavitation, the mechanical complexity which limits transmission power and the extra blade shaping requirements forced upon the propeller designer. For smaller motors there are self-pitching propellers. The blades freely move through an entire circle on an axis at right angles to the shaft. This allows hydrodynamic and centrifugal forces to 'set' the angle the blades reach and so the pitch of the propeller. A propeller that turns clockwise to produce forward thrust, when viewed from aft, is called right-handed. One that turns anticlockwise is said to be left-handed. Larger vessels often have twin screws to reduce heeling torque, counter-rotating propellers, the starboard screw is usually right-handed and the port left-handed, this is called outward turning. The opposite case is called inward turning. Another possibility is contra-rotating propellers, where two propellers rotate in opposing directions on a single shaft, or on separate shafts on nearly the same axis. One example of the latter is the CRP Azipod by the ABB Group. Contra-rotating propellers offer increased efficiency by capturing the energy lost in the tangential velocities imparted to the fluid by the forward propeller (known as "propeller swirl"). The flow field behind the aft propeller of a contra-rotating set has very little "swirl", and this reduction in energy loss is seen as an increased efficiency of the aft propeller. An azimuthing propeller is a propeller that turns around the vertical axis. The individual airfoil-shaped blades turn as the propeller moves so that they are always generating lift in the vessel's direction of movement. This type of propeller can reverse or change its direction of thrust very quickly,
  23. 23. Type of propellers In designing propellers, the maximum performance of the airplane for all condition of operation from takeoff, climb, cruising, and high speed. The propellers may be classified under eight general types as follows: 1. Fixed pitch: The propeller is made in one piece. Only one pitch setting is possible and is usually two blades propeller and is often made of wood or metal. Wooden Propellers: Wooden propellers were used almost exclusively on personal and business aircraft prior to World War II .A wood propeller is not cut from a solid block but is built up of a number of separate layers of carefully selected .any types of wood have been used in making propellers, but the most satisfactory are yellow birch, sugar marble, black cherry, and black walnut. The use of lamination of wood will reduce the tendency for propeller to warp. For standard one-piece wood propellers, from five to nine separate wood laminations about 3/4 in. thick is used. Metal Propellers: During 1940, solid steel propellers were made for military use. Modern propellers are fabricated from high-strength, heat-treated, aluminum alloy by forging a single bar of aluminum alloy to the required shape. Metal propellers are now extensively used in the construction of propellers for all type of aircraft. The general appearance of the metal propeller is similar to the wood propeller, except that the sections are generally thinner. 2. Ground adjustable pitch: The pitch setting can be adjusted only with tools on the ground before the engine is running. This type of propellers usually has a split hub. The blade angle is specified by the aircraft specifications. The adjustable - pitch feature permits compensation for the location of the flying field at various altitudes and also for variations in the characteristics of airplanes using the same engine. Setting the blade angles by loosened the clamps and the blades are rotated to the
  24. 24. desired angle and then tighten the clamps. 3. Two-position: A propeller which can have its pitch changed from one position to one other angle by the pilot while in flight. 4. Controllable pitch: The pilot can change the pitch of the propeller in flight or while operating the engine by mean of a pitch changing mechanism that may be operated by hydraulically. 5. Constant speed: The constant speed propeller utilizes a hydraulically or electrically operated pitch changing mechanism which is controlled by governor. The setting of the governor is adjusted by the pilot with the rpm lever in the cockpit. During operation, the constant speed propellers will automatically changes its blade angle to maintain a constant engine speed. If engine power is increase, the blade angle is increased to make the propeller absorb the additional power while the rpm remain constant. At the other position, if the engine power is decreased, the blade angle will decrease to make the blades take less bite of air to keep engine rpm remain constant. The pilot selects the engine speed required for any particular type of operation. 6. Full Feathering: A constant speed propeller which has the ability to turn edge to the wind and thereby eliminate drag and wind milling in the event of engine failure. The term Feathering refers to the operation of rotating the blades of the propeller to the wind position for the purpose of stopping the rotation of the propeller to reduce drag. Therefore, a Feathered blade is in an approximate in-lineof-flight position , streamlined with the line of flight (turned the blades to a very high pitch). Feathering is necessary when the engine fails or when it is desirable to shutoff an engine in flight.
  25. 25. 7. Reversing: A constant speed propeller which has the ability to assume a negative blade angle and produce a reversing thrust. When propellers are reversed, their blades are rotated below their positive angle , that is, through flat pitch, until a negative blade angle is obtained in order to produce a thrust acting in the opposite direction to the forward thrust . Reverse propeller thrust is used where a large aircraft is landed, in reducing the length of landing run. 8. Beta Control: A propeller which allows the manual repositioning of the propeller blade angle beyond the normal low pitch stop. Used most often in taxiing, where thrust is manually controlled by adjusting blade angle with the power lever.
