Gas Turbine Engine Quiz

Engine anti-ice is taken from the

• Turbine

• H.P compressor

• LP compressor

• Noise of inlet

In an axial flow turbine engine, compressor bleed air is sometimes used to aid in cooling the

• Inlet guide vanes

• Turbine, vanes, blades, and bearings

• Fuel

• Oil

If air is taken from the compressor for air conditioning or anti-icing

• Thrust will decrease EGT will increase

• Thrust will decrease EGT will decrease

• Thrust will increase EGT will decrease

• Thrust will increase EGT will decrease

Turbine case cooling utilizes

• LP compressor air

• Fan air

• H.P compressor air

• All of above

Air for anti-icing is taken from the

• Accessory Gearbox

• LP compressor

• H.P compressor

• Fan

As air is bled off the engine, EGT will

• Remain constant

• Change

• Increase

• Decrease

The heat absorbed by internal components can be detrimental to thrust and is prevented by

• Reducing fuel flow to reduce internal temperature

• Reducing fuel flow to increase internal temperature

• Bleeding air off the compressor to heat the components

• Bleeding air off the compressor to cool the components

On a gas turbine engine, thermal wing de-icing system derives air

• Via air from the H.P turbine

• Via air from the L.P turbine

• Through a pressure regulating shut-off valve (P.R.S.O.V)

• Through a pressure relief system

Inlet for cooling air for the first stage turbine blades is fed via the

• Blade root

• Blade holes

• Grill holes

• Leading edge of the blade

Air bleed for an anti-ice system is

• Tapped directly off the compressor

• Tapped directly off the Turbine

• Sent through a pressure regulator

• Sent through the air conditioning
