Abstract:
To overcome the obstacles existed in the fault detection for liquid-propellant rocket engines such as the lack of real-time．，in—time，and reliable．，a negative selection algorithm and an immune practical value algorithm based on the immune mechanism weFe researched and developed in the paper,，Results verified with a large amount of hot test data of a certain liquid—propellant rocket engine(LRE)showed that the algorithms could detect the faults occurred in the steady pro— cess of LRE efficiently and accurately．Thev can shorten the detection time compared with traditional algorithms．So it provides valuable reference for the development of future LRE artificial immune based fault detection and diagnosis system．．
