A performance test method for a small fluid thrust vector turbojet engine

Abstract

The present invention relates to the field of engine testing technology, specifically a performance testing method for a small fluid thruster turbojet engine, comprising acquiring collected data; performing statistical analysis on the collected data according to preset rules to obtain a comprehensive evaluation result of a scaled nozzle bench model; using a three-dimensional virtual model to analyze first simulation data to obtain a three-dimensional virtual result; performing comparative analysis on the comprehensive evaluation result and the three-dimensional virtual result to determine an average accuracy; when the accuracy meets a preset accuracy condition, performing a predictive analysis in a preset three-dimensional virtual model according to a second preset test list to obtain a predicted result; and using the comprehensive evaluation result and the predicted result as the final test result. The present invention solves the problem that when using a six-component box balance force measurement method to test the various performance characteristics of a small fluid thruster turbojet engine, if accurate test results are to be obtained, a large amount of manpower, material resources and time are required for testing.
