Gas-dynamic instability in the compressors of gas turbine engines, i.e., surging, can cause the failure of the compressor and the entire engine. The design is described here for a surge detection and correction system. A specific algorithm is derived which describes the gas-dynamic state of the engine and a block diagram of an antisurging system is presented. The proposed protector detects surging quickly with a sharp change in the temperature or pressure at the engine intake. When surge oscillations are due to other factors, the pressure increase following the compressor changes, which also actuates the protector.
