【Abstract】 Aero-engine high-altitude simulation test is one of the key aspects of engine system test. Aiming at the problems of many factors and complex levels in the high-altitude bench test, the test design method of improving the good lattice point method for uniform design and combining genetic algorithm for optimal design is studied. Through the verification of the typical scheme, it is shown that the test optimization rate of relative orthogonal design can reach 92.593%, and the test design method proposed in this paper is feasible for the high-altitude bench test.更多还原
