  2. 2. PRESENT & DESIGN BY:shubham katiyar B.TECH 7TH SEM. ROLL NO. :-1046510033 2
  3. 3. INTRODUCTION OF HAL ORGANIZATION Hindustan Aeronautics Limited (HAL) came into existence on 1st October 1964. The Company was formed by the merger of Hindustan Aircraft traces its roots to the pioneering efforts of an industrialist with extraordinary vision, the late Seth WalchandHirachand, who set up Hindustan Aircraft Limited at Bangalore in association with the erstwhile princely State of Mysore in December 1940. The Government of India Limited with Aeronautics India Limited and Aircraft Manufacturing Depot, Kanpur. The Company became a shareholder in March 1941 and took over the Management in 1942. Today, HAL has 19 Production Units and 10 Research and Design Centres in 8 locations in India. The Company has an impressive product track record - 15 types of aircrafts/Helicopters manufactured with in-house R & D and 14 types produced under license. HAL has manufactured over 3658 Aircrafts/Helicopters , 4178engines, Upgraded 272 aircraft and overhauled over 9643aircraft and 29775 engines. Tuesday, October 22, 2013 3
  4. 4. BASIC OF FLIGHT • THRUST • LIFT • DRAG • GRAVITY Tuesday, October 22, 2013 4
  5. 5. Aircraft Components A. Fuselage B. Wings C. Empenage or Tail D. Power Plant E. Landing Gear or Undercarriage Tuesday, October 22, 2013 5
  6. 6. Vertical Stabilizer Horizontal Stabilizer Wing Rudder Right Aileron Elevator Empennage Nacelle Fuselage Left Aileron Landing Gear Propeller Tuesday, October 22, 2013 Wing 6
  7. 7. Empennage • Know as tail section • Consist of – Vertical Stabilizer – Rudder – Horizontal Stabilizer – Elevators Tuesday, October 22, 2013 7
  8. 8. Power Plant A unit or machine that converts chemical energy contains in the fuel to thrust force. Thrust force is essential for moving the airplane forward and producing lift force. With the piston engine, the propeller is used to convert torque at engine shaft to be thrust. With the jet engine, the jet engine output is the thrust force. Tuesday, October 22, 2013 8
  9. 9. Landing Gear • Located underneath of the fuselage with shock strut • Fixed / Retractable • Provides means of landing taxiing • Tri- cycle –Conventional type • Floating gear for seaplane /skiequipped for ice surface landing etc.. Tuesday, October 22, 2013 9
  10. 10. Material use in Airframe Construction Airframe Materials Properties - High Strength to Weight ratio - Light weight - Corrosion Resistant - Should be non flammable - High quality Tuesday, October 22, 2013 10
  11. 11. Landing Gear Structure Airplanes with conventional landing gear are sometimes referred to as tail wheel airplanes. When the third wheel is located on the nose, it is called nose wheel, and the design is referred to as a tricycle gear. A steerable nose wheel or tail wheel permits the airplane to be controlled throughout all operations while on the ground. Tuesday, October 22, 2013 11
  12. 12. Power Plant The power plant usually includes both the engine and the propeller. The primary function of the engine is to provide the power to turn the propeller. It also generates electrical power, provides a vacuum source for some flight instruments, and in most single-engine airplanes, provides a source of heat for the pilot and passengers. The engine is covered by a cowling, or in the case of some airplanes, surrounded by a nacelle. The purpose of the cowling or nacelle is to streamline the flow of air around the engine and to help cool the engine by ducting air around the cylinders. The propeller, mounted on the front of the engine, translates the rotating force of the engine into a forward acting force called thrust that helps Tuesday, October 22, 2013 12 move the airplane through the air.
