Turbomachine e.g. turbojet engine, of aircraft, has compressor connected to diffuser for feeding combustion chamber, and sensor connected to monitoring unit for monitoring, regulating and/or controlling turbomachine

摘要

The turbomachine has a compressor (10) connected to a diffuser (20) for feeding an annular combustion chamber. Check valves (40, 42) comprise flaps (43) moving between an open position maintained by air flow supplied by the compressor, and a closed position in which return of air to the compressor through the valves during pumping is prevented. The valves are equipped with a sensor for detecting pressure difference between downstream and upstream areas of the valves. The sensor is connected to a monitoring unit (64) for monitoring, regulating and/or controlling the turbomachine.
