Question 1
Question
1. Which of these statements is false?
pg36
Answer
-
a) The pressurized air from the engine is enough for power pneumatic systems.
-
b) At ground APUs (Auxiliary Power Units) are used to provide pressurized air and electricity.
-
c) Jet engines use bleed air from compressor.
-
d) Reciprocating engines use bleed air from the turbocharger.
Question 2
Question
2. Has gas turbine pressure dependence on the shaft speed?
pg36
Answer
-
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.
-
d) b) apart from the compression ratio it depends on the outside temperature too.
Question 3
Question
3. The types of engine bleed systems are:
Answer
-
a) Intermediate and High pressure mixed systems.
-
b) Low and High pressure mixed system.
-
c) High isolated pressure system.
-
d) a) and b) are true.
Question 4
Question
4. Wich of these statements is true?
Answer
-
a) The pneumatic power has no return line
-
b) There’re no leakages and it’s easy to handle high pressures.
-
c) It’s the most common system to operate landing gears.
-
d) The pneumatic power systems need more tubing and valves than hydraulic systems.
Question 5
Question
5. The pneumatic systems are usually used to:
ph36
Answer
-
a) Operate landing gears
-
b) Move alerions.
-
c) Pressurize hydraulics reservoirs.
-
d) Operate the brakes.
Question 6
Question
6. Pneumatic systems in Harrier aircrafts are used to:
pg36
Answer
-
a) Operate the landing gear
-
b) Increase the speed during a conventional take off.
-
c) Give roll and pitch stability
-
d) Reduce the speed during a conventional landing.
Question 7
Question
7. Why does not the civil VTOL like the wing tips with pneumatic air to provide stability?
pg36
Answer
-
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.
