compressor bleed air

compressor bleed air

Air taken out of the compressor section of a gas turbine engine to prevent compressor stall and operate cabin pressurization and air-conditioning systems. Air may also be bled from the compressor for boundary-layer control.

The fuselage bleed-air line had ruptured inside the aircraft, and fourteenth stage compressor bleed air from the engines was blowing high-pressure, 900-degree Fahrenheit bleed air into the cabin.
These perturbations propagate throughout the engine and integrated subsystems that utilize compressor bleed air. Second, the engine model reduces the simulation time of a vehicle level T2T model tool making it feasible to simulate thousands of simulations needed for a complex optimization routine of a large system.
However, performance studies done by FRDC engineer Bob Abernethy showed that for a J58 application requiring continuous high Mach number afterburner operation, ducting compressor bleed air directly into the afterburner not only eliminated the stall margin limits, but it also provided better engine performance.
