摘要

采用一种基于Pareto最优解的多目标遗传算法—NSGAⅡ算法

以双轴混合排气式涡轮风扇发动机为算例

集成发动机性能模型、流路尺寸模型和质量模型

以单位推力、耗油率等为目标函数进行了多目标优化设计。计算结果表明:NSGAⅡ算法具有较好的稳健性和鲁棒性;基于NSGAⅡ算法的发动机总体性能优化方法能够获得目标空间内分布均匀的Pareto最优解集

有效克服了发动机总体性能方案设计时人工经验依赖较重的缺点

可为决策者进行目标权衡提供充分依据。

Abstract

Multi-objective optimization concepts

linked with a Pareto genetic algorithm-Non-dominated Sorting Genetic Algorithm(NSGA Ⅱ)

are applied to the preliminary design phase to automate the conceptual design process.Engine cycle selected for study was a mixed-stream

low-bypass turbofan.The robust analysis codes for the thermodynamic engine cycle

flowpath and weight estimation analyses were integrated to find higher quality design.The results showed that NSGA Ⅱ has better robustness and convergence than general multi-objective optimization methods

and could generate uniformly a Pareto optimal set in the design space.From this set

decision maker can choose the best overall optimum aircraft engine preliminary design.
