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
