The Gas Turbine Exhaust System Flashcards
1
Q
At what air flow velocity is the propelling nozzle choked?
A
M1.0
2
Q
What happens to temperature, pressure and velocity in the exhaust section?
A
Pressure and temperature fall but velocity may increase.
3
Q
How is noise reduced by shrouding?
A
High velocity, hot core exhaust gas is surrounded by the colder bypass air as it exhausts from the engine.
4
Q
On high bypass engines which air is used to produce reverse thrust?
A - Hot flow produced in the engine core
B - Cold bypass air?
A
B - cold bypass air
