Study Notes
Fuel System
- The primary function of the fuel system is to deliver fuel to the engine cylinders at the correct pressure and flow rate.
Fuel Injection System
- The fuel metering unit is responsible for metering fuel and piping it to the fuel manifold unit.
Combustion
- Abnormal combustion caused by an incompatible burning rate of fuel with the compression ratio and spark plug advance is usually detonation.
Aircraft Powerplant
- The primary purpose of an aircraft powerplant is to provide power for flight.
Powerplant Configurations
- A configuration of aircraft powerplants that is NOT typical is a single turboprop.
Reciprocating Engines
- The two primary designs of reciprocating engines are radial and inline.
Engine Components
- The crankshaft converts the reciprocating motion of the piston to rotary motion.
- The camshaft is responsible for operating the engine valves.
Wing Structures
- The primary materials commonly used in the construction of wing structures are aluminum and composite materials.
Aircraft Control Surfaces
- Ailerons are typically located on the trailing edge of the wing.
- The elevator, located on the tail, controls the pitch of the aircraft.
Propeller
- The function of a propeller is to convert the engine's energy into thrust.
- The angle of attack of a propeller is the angle between the propeller blade and the oncoming airflow.
Propeller Systems
- A constant-speed propeller system automatically maintains the selected RPM under varying conditions of airspeed and power.
- What distinguishes fixed pitch propellers from variable pitch propellers is the ability to change the propeller's pitch angle during flight.
