Air Bleed from engine compressor are used for

• service many aircraft user systems, also seal and cool the engine

• service engine aircraft system, also cool the engine

• seal the air inside the engine

• Cool, cleaning and reduce friction for engine

external use air typically bled from?

• Outlet of Lp Compressor and intake Hp Compressor

• Intake of Lp Compressor and Intake Hp Compressor

• Outlet of Lp Compressor and Outlet Hp Compressor

• Intake of Lp Compressor and Outlet Hp Compressor

Bleed air can be shut off from the engine by operation of?

• Inlet Guide Vanes

• Variable Stator Vanes

• Isolation Valve

• High Pressure bleed Valve

Air Bled used for internal cooling, which are for?

• Compressor disc area, combustion chamber cooling and compressor blade cooling

• sealing of bearing or turbine disc area, turbine blade cooling and combustion chamber cooling

• sealing of bearing or compressor disc area, turbine blade cooling and engine casing cooling

• Combustion chamber cooling or the turbine blade cooling, sealing or compressor disc areas

turbine blade cooling by using:

• By passing low pressure compressor air and high pressure turbine air creating boundary layer

• By passing high pressure turbine air and low pressure compressor air creating boundary layer effect

• By passing high pressure compressor air and low pressure creating boundary layer effect

• By passing high pressure compressor air and low pressure turbine creating boundary layer effect

Nozzle Guide Vane Cooling are cooled by using :

• Low Pressure Compressor air

• High Pressure Compressor air

• Low Pressure Turbine air

• High Pressure Turbine air

Disposing of Cooling And Sealing Air:

• LP air and HP air ejected into dedicated pipe

• Lp air and Hp air ejected into exhaust stream

• Lp air ejected into exhaust stream while Hp air ejected into dedicated pipe

• Lp air ejected into dedicated pipe while Hp air ejected into exhausted stream

sealing air used in bearing chambers, is taken from?

• High Pressure stages of compressor via Air Transfer Ports

• Low Pressure stages of compressor via Air Transfer Ports

• Intermediate Stages of compressor via Air Transfer Ports

• Intermediate Stages of Turbine via Air Transfer Ports

Common Lubrication Turbine Engine Systems :

• Pressure Relief Valve

• Full Flow Lubrication Systems

• Dry Sump

• Wet Sump
