1. FLIGHT MECHANICS Classification of Aircraft Presented by - Ganesh Natarajan S Target Audience : Gate Aerospace, Aerospace and Aeronautical Engineering Students, etc.

2. CORE TOPICS: Basics : Atmosphere: Properties, standard atmosphere. Classification of aircraft . Airplane (fixed wing aircraft) configuration and various parts. Airplane performance: Pressure altitude; equivalent, calibrated, indicated air speeds; Primary flight instruments: Altimeter, ASI, VSI, Turn-bank indicator. Drag polar; takeoff and landing; steady climb & descent ; absolute and service ceiling; cruise, cruise climb, endurance or loiter; load factor, turning flight, V-n diagram; Winds: head, tail & cross winds. Static stability: Angle of attack, sideslip; roll, pitch & yaw controls; longitudinal stick fixed & free stability, horizontal tail position and size; directional stability, vertical tail position and size; dihedral stability. Wing dihedral, sweep & position; hinge moments, stick forces. SPECIAL TOPICS: Dynamic stability: Euler angles; Equations of motion; aerodynamic forces and moments, stability & control derivatives; decoupling of longitudinal and lateral-directional dynamics; longitudinal modes; lateral-directional modes. SYLLABUS

3. CLASSIFICATION OF AIRCRAFT

4. Classification of Aircraft Aircraft Definition: A vehicle which is capable of flight by obtaining support from air is called as aircraft. Aircraft operates within the atmosphere E xamples of aircraft are airplanes, helicopters, airships, gliders and hot air balloons. Methods of Classification: Aircraft can be classified based on many methods Type of Lift Generation Propulsion system Mach Number (Speed) Purpose Range Mode of Take-off and Landing Size and Payload capacity Power source Others

5. Landplane Seaplane Amphibian Sea Ornithopter Amphibian Gyroplane Helicopter Land Ornithopter GENERAL CLASSIFICATION

6. LIGHTER THAN AIR Aircraft Heavier THAN AIR Aircraft Kept aloft by gas, which is generally lighter than air. They depend on two types of lift, aerodynamic lift and powered lift Technically termed as aerostat Technically termed as aerodyne They are used almost only for recreational and research purposes. They are commonly used for aviation means. E.g.: Hot Air Balloon, Airship E.g.: Aeroplane, helicopter, Ornithopter

7. Classification based on mach number: •  Subsonic (M<1) • Transonic (M~1) • Supersonic (M>1) • Hypersonic ( M>5) Classification based on type of engine: •  Propeller • Turboprop • Turbofan • Turbojet • Ramjet OTHER CLASSIFICATION

8. Classification based on purpose: • Passenger Transport • Business jets • Cargo Transport • Experimental aircraft •  Trainers • Military aircraft Fighters Bombers Medical / Rescue Aircraft Spy / Reconnaissance Aircraft •  Agricultural aircraft • Sports aircraft Glider Recreational aircraft Man-powered aircraft OTHER CLASSIFICATION

9. Classification based on size and payload capacity: • Micro-airplanes • Single or double seater airplanes • Medium size airplanes (~50 passengers) • Large airplanes (~ 400 passengers) • Cargo planes Classification based on source of power: • Oil • Solar power • Electric power • Nuclear power OTHER CLASSIFICATION

10. Classification based on number of wings: • Monoplanes • Biplanes etc. Classification based on range: • Short range (<500 km) • Medium range (<3000km) • Long range (>3000 km) Classification based on mode of take-off and landing: • Normal • Vtol • Stol • STOVL etc OTHER CLASSIFICATION

11. Special Aircraft: • Helicopter •  Ornithopter or Flapping wing aircraft • Flying Wing Aircraft • Stealth Aircraft OTHER CLASSIFICATION
