Resource summary

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.

  • 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

  • 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.
