针对组合循环动力系统应用于高超声速飞行器的背景,构建了组合循环发动机(简称组合发动机)性能指标体系框架。采用AHP方法确定了组合发动机性能指标权重分布,建立了基于AHP的组合发动机性能评估方法。本方法可通过对不同组合动力方案综合性能的量化评价,为高超声速飞行器方案优化设计提供参考。
Aiming at the background that combined cycle power system is applied to hypersonic vehicle, a framework of performance index system of combined cycle engine (referred to as combined engine) is constructed. AHP method was used to determine the weight distribution of the combined engine performance index, and a method to evaluate the performance of the combined engine based on AHP was established. The method can provide a reference for the optimization design of hypersonic vehicles through the quantitative evaluation of the comprehensive performance of different combinations of power schemes.
