| Abstract: | On basis of the ground test of liquid rocket engines a monitoring system is developed,of the system basic architecture, fault detecting algorithm and realized projects of the software andhardware are given. The fault detecting algorithm and the cutofflogics are testified through a largenumber of test patern. The verified results show that ACSB detecting algorithm is much better thanred-line system in fault diagnosis. |
