Kinetic
Energy is defined as what?
Something that gives us the capacity to perform work
Work and energy are measured in what unit?
Joules
What is potential energy defined as?
Energy at rest or energy that is stored
Kinetic energy is defined as what?
Energy in motion
What is Newton’s first law?
Law of inertia
Four stages of engine?
Intake (Suck)
Compression (Squeeze)
Expansion (Bang)
Exhaust (Blow)
Four ideal changes of state?
Isobaric
Isochoric
Isothermal
Isentropic
What is isobaric heating?
Heat being added to air in combustion chamber by adding fuel to increase volume of air
Formula equation for thrust of engine?
Force= Mass x Acceleration
Two types of aircraft engines?
Piston type engine
Gas turbine engine
4 types of gas turbine engines?
Turbojet engine
Turbofan engine
Turboprop engine
Turboshaft engine
What is the most common commercial aircraft engine?
Turbofan
Cold and hot sections of engine?
Cold= Intake and compressor
Hot= combustion chamber and exhaust
What altitudes can gas turbine engines operate to?
Very high altitudes
What is a spool?
A turbine driving a compressor through a shaft
Turboprop are designed to produce what type of power?
Shaft horsepower only
What type of engine is the apu normally?
Turboshaft engine as it produces shaft horsepower to drive machinery and not thrust
