From which section of the engine is bleed air typically sourced?

Bleed air is typically sourced from the compressor section of a turbine engine. This section is responsible for compressing the incoming air to a higher pressure before it enters the combustion chamber. The air extracted from this section is used for various purposes such as environmental control systems, anti-ice systems, and starting the engines. The compressor operates at high pressures, making this bleed air effective for such applications.

The other sections of the engine do not serve the same function for bleed air extraction. The combustion section, for instance, is where fuel is burned with the compressed air to produce high-temperature and high-pressure gas, which is not suitable for bleed applications. The turbine section generates power to drive the compressor and other accessories, but it does not supply bleed air. Finally, the exhaust section deals with expelling the gases resulting from combustion, and while it may be used for thrust, it does not provide bleed air. Therefore, the compressor section is the appropriate source for bleed air within a turbine engine.
