Exhausts Flashcards
1
Q
What thrust comes from the exhaust
A
Pressure thrust!
2
Q
What do poorly designed exhausts cause
A
Excessive back pressure which can lead to compressor stall and surge
3
Q
Propelling nozzle
A
Increases the velocity and decreases the pressure of the gas stream
4
Q
Tail cone design purpose is to
A
Slow gases to minimise friction loss
5
Q
High bypass turbofan reverses are
A
Hydraulically operated and reverse the cold thrust of the engine
6
Q
Bucket reversers
A
Hydraulically operated and reverse all the thrust of the engine
7
Q
Clamshell reversers
A
Pneumatically operated and reverse all engine thrust
