From which section of a turbo-jet aeroplane is engine bleed air typically taken for air conditioning?

Engine bleed air for air conditioning systems in a turbo-jet aeroplane is typically taken from the compressor section. The compressor section operates at high pressure and temperature, making it suitable for supplying bleed air that is both sufficient in volume and at the correct conditions to effectively meet the needs of the air conditioning system.

The air taken from the compressor section can be conditioned and then distributed throughout the cabin to maintain a comfortable environment for passengers and crew. This air is typically extracted upstream of the combustion process, ensuring that it bypasses any potentially harmful exhaust gases.

The design of the engine allows for this significant extraction of air, which is a crucial operational aspect for ensuring that the environmental control systems within the aircraft function efficiently. The compressor is engineered to provide this bleed air without significantly impacting engine performance.
