摘　　要：以倾转旋翼机为代表的新一代民用高速旋翼飞行器缺乏参考样机和统计数据,在前期设计阶段难以准确地根据市场需要提取各项能力需求,对各项指标进行权衡优化。本文通过K-Means聚类分析方法和粒子群算法,构建了一种倾转旋翼机能力需求指标优化框架,建立了以展弦比、桨尖速度等技术参数为输入,以最大飞行速度、最大悬停高度等性能参数为输出的倾转旋翼机性能估算模型。并在此基础上构建了一套能力需求指标优化算法,该算法能够以任务需求或任务剖面集为输入,对能力需求指标进行整理,生成基于最优分类原则的一系列任务簇,在每个任务簇中开展基于任务效能仿真的能力需求指标优化计算,最终输出优化后的效能最优且可行的倾转旋翼机性能指标、技术指标序列,完成对能力需求指标的转化与优化,为论证、研制等提供支撑和参考。Civil high-speed tiltrotor aircraft represented by tiltrotors lacks data and references,and it is difficult to accurately extract requirements from the market and optimize indicators in the preliminary design stage.In this paper,a capability requirement index optimization model for tiltrotor aircraft based on K-Means algorithm and particle swarm optimization algorithm is developed.A performance estimation model for tiltrotor aircraft is established,with technical parameters such as aspect ratio and blade tip speed as inputs and performance parameters such as maximum speed and maximum hover altitude as outputs.Based on this model,a capability requirement index optimization algorithm is developed,which can organize the capability requirement index with task demands or task profile sets as input,generate task clusters based on optimal classification.Within each task cluster,ability requirement optimization is conducted by task efficiency simulation,and the optimized and feasible tiltrotor aircraft performance and technical index are output,completing the transformation and optimization of the capability requirements indicators,and providing support for tiltrotor development.
