Pregunta 2
Pregunta
2. Has gas turbine pressure dependence on the shaft speed?
pg36
Respuesta
-
a) Yes, it has a strong dependence.
-
b) No, gas turbine pressure depends on the compression ratio of the compressor.
-
c) a) and there must exist an engine bleed air control system.
-

Pregunta 6
Pregunta
6. Pneumatic systems in Harrier aircrafts are used to:
pg36
Respuesta
-
a) Operate the landing gear
-
b) Increase the speed during a conventional take off.

Pregunta 7
Pregunta
7. Why does not the civil VTOL like the wing tips with pneumatic air to provide stability?
pg36
Respuesta
-
a) Esthetically it’s not attractive.
-
b) They harm the aerodynamic.
-
c) They are not effective.
-
d) Because if the compressor fails, the aircraft lose the roll and pitch stability.
