Gas Turbines Puzzles on “Dimension Parameters of Aircraft Plants”.
1. Thrust to weight ratio for an airplane is found _______ the takeoff.
a) after
b) before
c) during
d) none of the mentioned
Answer: b
Clarification: Thrust to weight ratio for an airplane is found at the time of intake.
2. Take off mass value for an airplane is found ________ the takeoff.
a) after
b) during
c) before
d) none of the mentioned
Answer: c
Clarification: Take off mass value for an airplane is found before the takeoff during intake. When it is taken after takeoff some fuel might be utilised and mass may be varied.
3. Landing gear for an airplane is selected depending on the engine _________
a) thrust
b) torque
c) torque & thrust
d) none of the mentioned
Answer: a
Clarification: Landing gear for an airplane is selected depending on the engine thrust.
4. Take off mass value also effects the selection of __________
a) drag force & landing gear
b) drag force
c) landing gear
d) none of the mentioned
Answer: c
Clarification: Engine thrust and take off mass value both effects the selection of landing gear.
5. Dimensions of an airplane are effected by the engine _______
a) torque
b) thrust
c) torque & thrust
d) none of the mentioned
Answer: b
Clarification: Dimensions of an airplane can be effected the available engine thrust i.e depending on the engine thrust airplane dimensions are selected.
6. Wing area in an airplane is ________ proportional to take off mass value.
a) not related
b) inversly
c) directly
d) none of the mentioned
Answer: c
Clarification: Wing area of an airplane is directly proportional to take off mass value.
7. Fuel mass required in an airplane is _________ proportional to the take off mass value.
a) directly
b) inversly
c) not related
d) none of the mentioned
Answer: a
Clarification: Fuel mass required in an airplane is directly proportional to the take off value.
8. Fuselage dimensions in an airplane is _________ proportional to cross sectional area of fuselage.
a) inversly
b) directly
c) not related
d) none of the mentioned
Answer: b
Clarification: Fuselage dimensions in an airplane is directly proportional to cross sectional area of fuselage.
9. Rare fuselage length of an airplane is _______ proportional to the diameter of the fuselage.
a) directly
b) inversly
c) not related
d) none of the mentioned
Answer: a
Clarification: Rare fuselage length of an airplane is directly proportional to the diameter of the fuselage.
10. Geometric dimensions of an airplane are required for estimation of the weight of airplane.
a) True
b) False
Answer: a
Clarification: Geometric dimensions of an airplane effects the weight of the airplane.
