The Olympic and Titanic have been built. The HMHS (His Majesty's Hospital Ship) Britannic was the third " wonder ship" to be built. Originally, the ship was to be named " Gigantic ", but due to the loss of the Titanic, her name was changed to Britannic. The White Star Line knew if they were to keep ahead in the race across the Atlantic the new liner would have to be more magnificent than her older sisters.
Due to the sinking of the Titanic, large scale alterations would have to be made to her design. She could not sink in under 3 hours. She must carry enough lifeboats to accommodate every passenger and crew member.

Solution
On December 17, 1903, Orville and Wilbur Wright capped four years of research and design
efforts with a 120-foot, 12-second flight at Kitty Hawk, North Carolina - the first powered flight
in a heavier-than-air machine. Prior to that, people had flown only in balloons and gliders. The
first person to fly as a passenger was Leon Delagrange, who rode with French pilot Henri
Farman from a meadow outside of Paris in 1908. Charles Furnas became the first American
airplane passenger when he flew with Orville Wright at Kitty Hawk later that year.
Aircraft Innovations
For the airlines to attract passengers away from the railroads, they needed both larger and faster
airplanes. They also needed safer airplanes. Accidents, such as the one in 1931 that killed Notre
Dame Football Coach Knute Rockne along with six others, kept people from flying
Aircraft manufacturers responded to the challenge. There were so many improvements to aircraft
in the 1930s that many believe it was the most innovative period in aviation history. Air-cooled
engines replaced water-cooled engines, reducing weight and making larger and faster planes
possible. Cockpit instruments also improved, with better altimeters, airspeed indicators, rate-of-
climb indicators, compasses, and the introduction of artificial horizon, which showed pilots the
attitude of the aircraft relative to the ground - important for flying in reduced visibility.
designers already knew that as an aircraft approaches the speed of sound (Mach 1), in the
transonic region, shock waves begin forming, causing a large increase in drag. Wings, already
thin, had to become thinner and finer. Fineness is a measure of how thin the wing is compared to
its front-to-back chord. A small, highly loaded wing has less drag and so some early types used
this type, including the Bell X-1 rocket plane and the Lockheed F-104 Starfighter. But these craft
had high takeoff speeds, the Starfighter causing significant pilot deaths during takeoff, and small
wings fell out of use. An approach pioneered by German designers during the war was to sweep
the wing at an angle, delaying the buildup of shock waves. But this made the wing structure
longer and more flexible, making the aircraft more likely to suffer from bending or aeroelasticity
and even causing a reversal in the action of the flight controls. Stall behaviour of the swept wing
was also poorly understood and could be extremely sharp. Other problems included divergent
oscillations which could build up lethal forces. In re.

Development of steam powered ships
And transformation in naval warfare
A steamship, often referred to as a steamer, is an ocean faring seaworthy vessel that is propelled
by one or more steam engines that typically drive (turn) propellers or paddlewheels. The first
steamships came into practical usage during the early 1800s;
The first steam engines worked by filling a cylinder with steam, then condensing it to water. The
vacuum created drew the piston into the cylinder. These “atmospheric” engines were useful for
pumping out mines and other tasks where their weight was not important. They were far too
heavy and bulky to use aboard ships, however. James Watts’s improved steam engine drove the
piston in the opposite direction—expanding steam, rather than atmospheric pressure on a
vacuum was the driving force. Such engines could be made small enough to power a ship. Their
earliest use was to turn a pair of huge side wheels.
Steam gave navies a great strategic advantage. Steam warships no longer depended on weather
and could cross the oceans much faster than sailing ships. “Seizing the weather gauge”
(maneuvering into the best location to take advantage of the wind) had long been a favorite tactic
of British seamen. It no longer gave any advantage. For that reason, Britain, although it was the
home of the first steam engines and it utterly depended on its navy for its primacy in world
affairs, tried to retard the development of steam-powered ships. British naval personnel were the
most skilled in the world; British shipyards devoted to building sailing men-of-war were the
biggest in the world; British technology in preserving food for long journeys, manufacturing the
heavy, short-range cannons, called carronades, and everything else needed for wooden, sail-
driven warships, led the world. If the world’s navies went to steam, all of that would be
worthless.
In 1828, the British admiralty expressed their views on steam-powered warships:
Their lordships feel it is their bounden duty to discourage to the utmost of their ability the
employment of steam vessels, as they consider that the introduction of steam is calculated to
strike a fatal blow at the naval supremacy of the Empire.
Steamships. In his classic study, Sea Power in the Machine Age, Bernard Brodie observed that
navies were relatively late in utilization of the technological advances of the machine age.
Progress in steampower development was followed closely by the various admiralties—Great
Britain, France, and the United States being most active. During the nineteenth century, the
steam warship was by far the most important of the great naval revolutions, the most significant
such innovation in warships since the fifteenth century. Steampower completely revised naval
tactics and strategy; now ships could go anywhere, any time. During a transition period at
midcentury, the largest warships retaine.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Sea harrier frs
1. SEA HARRIER FRS.1
HISTORY
Naval Aviation British has had a slow death, losing its fighter squadrons fixed
wing at least twice, in the seventies the last aircraft carrier HMS Ark Royal
retired, leaving if coverage air fleet, with much work yu no few tricks, the
Admiralty managed to recover some of the combat power of the fleet, with a
couple of "cruisers clear deck", a euphemism to deceive the bureaucrats and
afford to build new aircraft carriers, to equip these vessels, it was decided use a
derivative of Harrier of the RAF, a multipurpose aircraft vertical takeoff, so I
emerged the Sea Harrier, which appeared in one of the most desperate
moments of modern history of Britain, the first devices were indispensable to
recover the Falkland islands , giving insufficient protection screen aerial fleet,
demolishing a large number of Argentine aircraft, but there was never enough
aircraft to provide adequate CAP and many planes could slip.
Although from the beginning of the development of the Harrier in the sixties it
was thought in its board use tests being carried off and landing on conventional
aircraft carrier, the elimination of the Fleet Air Arm in the seventies, ended the
naval development, almost a step-decade until it could reconstitute units fixed
wing, reconstituting the 797 Squadron, with Sea Harriers training and
preproduction fighters, for the first ship of the class,
The BAe Sea Harrier FRS1 was designed with no few complications, the Harrier
had entered the service of the RAF in the late seventies, immediately proved to
be a magnificent instrument of combat, unmatched by any other British unit
performance, despite being ominous for the Royal Navy, this kept a watchful
development of the Harrier eye, originally planned as attack aircraft, was that he
had very good performance as an apparatus of hunting, becoming one of the
first and most efficient multi-role aircraft in the world times. The
modificacionesfueron, a higher cabin deck operations, metal parts corrosion
2. resistant, watertight compartments to increase its buoyancy, navalized beacon
of direction, electronica latest navigation and a different radar
The design of the Harrier had arisen as the first VTOL aircraft, this involved a lot
of research and not a few radical ideas, the essence is the engine and nozzles,
a powerful Pegasus engine capable of delivering an output of ----, enough to
support its own push the weight of the fully loaded device, to direct the thrust
vectoring engine, it was necessary to place the vector based on the center of
the apparatus, however, a nozzle capable of lifting and directing forward the
apparatus was not possible place in the center of gravity was replaced by four
rotational on the sides of the fuselage, equidistant from the center of gravity
nozzles, this gave a very graceful appearance on the plane with a huge and
very bulky fuselage, and that was one of his limiting, besides the enormous
aerodynamic drag, as the device reaches a minimum height, its radar signature
is unmistakable, to compensate for this lack, the aerodynamics was very
elaborate, smooth fuselage and wings delta, although very small, if the fuselage
was reduced to a minimum, only the most essential, the cockpit, radar,
undercarriage, engine, and an extraordinary landing gear, two-pronged, to
balance the weight of the fuselage one put forward and one back of the engine,
this forced add guns out of the fuselage, a clear order to place under the
fuselage an auxiliary tank or pump height was left, but rarely use, the place was
best used by placing 30mm cannon Aden. The payload on the wings was very
good, thanks to a very good structure and four hardpoints, which could be fitted
3. with bombs, rocket launchers or fuel tanks, later defensive weapons were
added, the Sidewinder missile with all its wiring and guns 20 mm.
The Sea Harrier was approved in 1979, and development began immediately,
first to correct was the cabin, which for naval operations needed to be higher,
this parrot increasing the fuselage, a new more modern radar and electronics
were added in one reconfigured cone, also watertight compartments, a
reinforced train and the whole structure was added was revisdad to replace
materials readily oxidized by naval materials, a system more advanced
navigation and provision to carry and launch naval weapons and missile Sea
Skua , also from the beginning it was thought at the Sea Harrier as a naval
fighter, equipped with Sidewinder and 30mm cannons, plus an efficient system
of air defense control. After the Falklands campaign, is developing a new
version of the FA.2, with the lessons learned from the conflict, a new radar
pulse, the ability to bring new AMRAAM, a new Pegasus Mk 106 engine, more
fuel a new avionics and sisitema automatic landing, although this has rarely
been used.
Operational History of Sea Harrier began almost immediately on entering the
service, the first squadron to receive the apparatus was the 797 OCU, shortly
after there was sufficient equipment to form a unit, the 800th Squadron,
intended to serve aboard HMS Hermes , and had begun the formation of a
second squadron 801, intended to serve on HMS Illiustrious, when Argentina
occupied the Falkland Islands, when sending set down to the fleet to recover,
the situation was serious, one aircraft carrier well equipped, other without air
group, hastily was reformed 801, with pilots and aircraft 797, leaving behind
only three seater aircraft, the needs of attack would be covered by Harriers
RAF, which would operate from aircraft carriers, even so, it was too ocean for
very few planes, when they reached the combat zone, was established a CAP,
but very thin, without any AWAC, Argentine aircraft found many holes where
slip, causing great damage to British ships, despite this, the Harriers made a
very good job, knocking down a lot of Argentine aircraft, and defending the fleet,
because even with losses, achieving all its objectives, failures must be seen
elsewhere in the decision of the British government to withdraw the carriers and
4. fleet air cover, it is very unlikely that Argentina managed to sink a single aviation
vessel if the Royal Navy had told even with HMS Ark Royal and its endowment
Phantoms.
While the Falklands were their moment of more fame, it was not the only
operation in which appeared the Sea Harrier, subsequently intervened in the air
control over Bosnia in 2000 operated in support of the British forces in Sierra
Leone, Gulf War against Iraq. Although originally thought to replace them with a
version navalized of GR.7 not se hizo anything about it and the few units of the
fleet were withdrawn in 2006, without replacement, 801 NAS was disbanded
and again, was the Aviacion end of the fixed wing of the Royal Navy.
The Sea Harrier was exported to several countries, India uses it in its original
form, while the navies of the United States, Italy and Spain use the American
version, with electronics and weapons from that country.
