Abstract: In order to meet the requirements of turbo-fan engine fault diagnosis,a kind of rapid prototype simulation design way based on the baseline of the engine for gas-path fault diagnosis was proposed.Considering the precision of the fault diagnosis in the flight envelope influenced by the engine baseline,optimal transformation index was selected in simulation transformation for the setup of baseline.The weighted least-squares algorithm was used to design the fault diagnosis model,which was downloaded to National Instrument (NI) CompactRIO to form rapid prototype simulation system.A series of test experiments on a turbo-fan engine show the effectiveness of this rapid prototype design method for gas-path fault diagnosis.-
