Abstract

See full text

The present application provides a process for preventing rotating stall and surge in a turbomachine compressor. The compressor may include air extraction pipes connecting the compressor to a turbomachine exhaust area or to the atmosphere, at least one of the pipes is fitted with a flow regulation valve, and each valve has an adjustable degree of opening. The process includes, for at least one of the valves, a complete opening command when the compressor rotation speed is less than a predetermined threshold value beyond which there is no longer any risk of rotating stall and surge and a command for lowering the degree of opening of the valve when the rotation speed of the compressor exceeds the threshold value.
