Questions and Answers

What is the primary function of flaps on an aircraft?

  • Reduce fuel consumption at high altitudes
  • Improve stability during turns
  • Increase drag for slower cruising speeds
  • Increase lift and drag for slower takeoff and landing speeds (correct)

    • What is a key characteristic of Fowler flaps?

  • They control yaw
  • They reduce drag by smoothing airflow over the wing
  • They are located on the leading edge of the wing
  • They extend rearward, increasing wing area and lift (correct)

    • Leading-edge flaps are designed to:

  • Increase the surface area of the wing
  • Prevent airflow separation at high angles of attack (correct)
  • Improve longitudinal stability
  • Decrease drag during takeoff

    Study Notes

    Aircraft Flaps

    • Primary function: Increase lift and drag for slower takeoff and landing speeds
    • Fowler flaps: Extend rearward, increasing wing area and lift
    • Leading-edge flaps: Prevent airflow separation at high angles of attack

    Aircraft Spoilers

    • Primary function: Decrease lift and increase drag during landing

    Engine Components

    • Camshaft: Controls opening and closing of valves
    • Crankshaft: Converts linear motion of the pistons into rotational motion
    • Power stroke: In a four-stroke engine, this is the stroke that produces power

    Engine Types

    • Two-stroke engines: Fewer moving parts and simpler design
    • Diesel engines: Compress air to ignite fuel

    Aircraft Brakes

    • Disc brakes: Offer better cooling, reduced brake fade, and improved braking performance

    Landing Gear

    • Oleo struts: Absorb shock during landing
    • Tricycle landing gear: Better ground handling and forward visibility

    Aerodynamics

    • Speed of sound: Affected by pressure, temperature, and density
    • Speed classifications:
      • Subsonic: Below Mach 1
      • Supersonic: Between Mach 1 and Mach 5
      • Hypersonic: Above Mach 5
    • Shockwaves: Typically form on the nose and wing leading edges

    Engine Power

    • Brake horsepower (BHP): Power available at the crankshaft
    • Turbochargers: Use exhaust gases to generate boost
    • Superchargers: Mechanically driven by the engine

    Aircraft Wing Designs

    • Canard wings: Improve pitch stability and delay stall
    • Winglets: Reduce drag caused by wingtip vortices
    • Vortex generators: Energize the boundary layer on a wing to prevent flow separation

    Flight Controls

    • Ailerons: Control roll
    • Elevator: Controls pitch
    • Rudder: Controls yaw

    Aircraft Construction Materials

    • Composite materials (carbon fiber, fiberglass): Offer high strength-to-weight ratios and corrosion resistance
    • Honeycomb structures: Provide excellent strength with minimal weight
