DCRSM-based aeroengine cycle selection approach for multi-operating conditions performance reliability

Abstract

Abstract The aim of the present research is to purpose a new aeroengine cycle design approach for multiple operating conditions performance reliability based on Distributed Cooperative Response Surface Method (DCRSM). A steady-state component level engine model is developed to simulate the overall performance with impact of uncertainty. After solving the distributed response surface model, The cooperative performance reliability response surface model is established for cycle optimization design. The effectiveness of this approach is validated by the randomized trial, which show that cycle parameters from the Pareto-optimal set generated by NSGA II can make the engine performance meet high reliability simultaneously under all expected conditions.
