From which part of the engine is bleed air taken?

Bleed air is primarily taken from the compressor section of the engine. In a jet engine, the compressor is responsible for increasing the pressure of the incoming air before it enters the combustion chamber. This high-pressure air can be diverted, or "bled off," from specific stages of the compressor for various uses.

One of the main applications of bleed air is for engine starting or providing cabin air for environmental control systems, as well as de-icing applications. The compressor is designed to provide airflow at a high pressure and temperature, making it ideal for these purposes.

The other sections of the engine—the combustion section, turbine section, and inlet section—are not typically where bleed air is drawn. The combustion section is focused on the mixing of fuel and air for combustion, the turbine section extracts energy from the high-velocity exhaust to drive the compressor, and the inlet section is where the engine takes in ambient air but does not provide usable bleed air. Thus, the compressor section is the correct source from where bleed air is taken in a jet engine.
