Sheet 5 Flashcards
Turbo-prop engine comes from the turbine exhaust
A small acceleration to a small mass of air
Continuously
The L.P turbine is connected to the L.P compressor, the H.P turbine is connected to the H.P compressor
5 pounds of air is by-passed for every 1 pound that goes through the hot core of the engine
The velocity increases before the combustion chamber
The rearmost turbine
Cools the combustion chamber and therefore increases the thermal efficiency
A decrease in ambient temperature
Will decrease
Cold stream air to that flowing through the hot core of the engine
Newton’s Third Law of motion
Large expansion at a substantially constant pressure
The pressure temperature increases and the velocity decreases
Their velocity increases and their temperature and pressure decrease
Low by-pass ratio turbo jet, Pure turbo jet, Turbo prop, High by-pass ratio turbo jet
Between the compressor and the combustion chamber
The turbine
Not all the air goes through the high pressure compressor
Enables malfunctioning sections of the engine to be changed without changing the whole engine
