摘　　要：针对航空动力系统整机设计优化中存在的计算规模庞大、耦合关系复杂、学科冲突尖锐、实现过程困难等问题,从系统分解、系统建模和系统求解3个方面,发展并应用了高精度代理模型、高效优化策略和智能多目标优化算法等多类先进技术,并建立了基于多学科设计优化(MDO)的航空动力系统整机设计方法。分别以涡轴发动机、涡扇发动机、涡喷发动机、直升机传动系统主减速器主传动链为对象开展了航空动力系统整机MDO工程应用研究,并针对涡喷发动机进行了优化后压气机性能和强度试验验证以及整机试验验证。研究表明:航空动力系统整机MDO能够有效释放设计潜能,显著提高产品综合性能,大幅缩短研制周期,其工程应用前景十分广阔,将变革航空动力系统设计及研发工作。In view of the difficulties in the design optimization of an overall aircraft power system,such as the considerable calculation scale,complex coupling relationships,sharp discipline conflicts and complicated implementation processes,a variety of advanced technologies such as the high-precision surrogate models,the efficient optimization strategies and the intelligent multi-objective optimization algorithms were developed and applied in three aspects:system decomposition,system modelling and system solution.Finally,the design method of an overall aircraft power system based on multidisciplinary design optimization(MDO) was established.Taking a turboshaft engine,a turbofan engine,a turbojet engine and a main transmission chain of the main reducer of a helicopter transmission system as examples,the engineering application research on MDO of the overall aircraft power system was carried out.Moreover,the performance and strength tests of the optimised compressor,and the optimised overall system test were carried out and verified for the turbojet engine.The research showed that the MDO of the overall aircraft power system could effectively unleash the design potential,significantly improve the comprehensive performance of products and considerably shorten the development cycle.Its engineering application prospect is quite broad,which will change the design and development of an aircraft power system.
