Unit 2 Flashcards
What is the forward-driving force that the expelled mass of air creates?
Thrust
What is needed to overcome drag?
Force
Three different types of engines that power most of the aircraft in the airforce inventory.
Turbojet, Turboprop, and Turbofan
Temperature of atmosphere’s relation to power output of engine
High temperature = Lower power
Low temperature = High power
Aka They work in inverse
Pressure of the atmosphere in relations to the power output of the engine
Low Pressure = Low Power
High Pressure = High Power
Aka They scale together
What is a non-combusted air that is pulled from an engine to run pnuematic systems?
Bleed Air
When bleed air is extracted from the engine, what happens?
A small portion of thrust is lost
What jet engine component channels incoming air into the compressor?
Air Inlet
What jet engine component supplies air in sufficient quanity to produce the required engine thrust?
Compressor
This compressor component are small airfoil blades attached to a spindle
Rotors
This compressor component are airfoil blades fixed in the engine; THEY DO NOT ROTATE. BIG HINT THEY STAY!!
Stators
What jet engine component slows down the air discharged by the compressor?
Diffuser
Where is the fuel mixed with compressor discharge air and then IGNITED?
Combustion Chamber
What jet engine component transforms a portion of the exhaust gas energy into mechanical energy?
Turbine
What jet engine component directs the flow of hot gases leaving the turbine?
Exhaust
