Evaluation of Equipment Performance for Altitude Test Facility Flight Environment Simulation System
Abstract— Based on the predictive maintenance requirements of aero-engine Altitude Test Facility (ATF) equipment, a test equipment performance evaluation method (PCA-SPR) combining principal component analysis (PCA) and statistical pattern recognition (SPR) is proposed. It uses the PCA method to reduce the dimensionality of the equipment features, and recognizes the equipment status based on SPR. Then it defines the equipment health indicators based on the sample similarity theory, and achieves the quantitative evaluation of the equipment status. This paper takes the special control valve of ATF as the research object. Based on the simulation platform of the ATF flight environment simulation system, the valve performance degradation mode is studied and the valve degradation simulation is performed. The proposed PCA-SPR algorithm is applied to the valve performance evaluation to verify the applicability of the algorithm.
Index Terms— Altitude Test Facility, test equipment, performance evaluation, principal component analysis, statistical pattern recognition.
