直升机总体参数优化设计

 根据直升机的飞行性能、稳定性、发动机和重量的要求,建立优化的分析模型,应用计算机和最优化技术求解,得到满足直升机设计准则的最佳总体设计方案。本方法也可用于对已有型号的总体参数分析和参数敏感性分析。通过算例和新机设计中的应用表明,本方法对直升机总体参数选择是行之有效的。

OPTIMIZATION DESIGN OF HELICOPTER FOR PRELIMINARYPARAMETERS

In the paper, a new design method for preliminary parameters is proposed. The analytic models of the optimization design are established acording to the requirements of the flying performance, stability, engine and weight. The optimal preliminary project of design to meet the requirements of criterion for helicopter design is worked out by applying the computer and optimization techniques in the paper. The method is used for the analysis of helicopters for preliminary parameters that are used in practice and for the analysis of sensibility for preliminary parameters, too. The method is shown to be very useful by the example and applicable in the new design of helicopters.
