摘要

Traditional coupled multidisciplinary design optimization based on computational fluid dynamics/computational structure dynamics (CFD/CSD) aims to optimize the jig shape of aircraft, and static aeroelastic analysis is used to get the aero-structural performance. The huge computational expense hampered its application in engineering. Now we put forward an efficient methodology to predict the aero- structural performance of aircraft: reverse iteration of structural model(R1SM), which is far more efficient than the conventional loosely- coupled aeroelastic analysis. A multidisciplinary design optimization framework based on RISM and surrogate model is proposed. Test show that RISM is four times faster than loosely-coupled aeroelastic analysis. A wing-body configuration was optimized by the proposed framework successfully, which shows the effectiveness of the proposed framework.
