摘要
直升机气动布局参数对直升机的飞行性能有着显著的影响,使用多目标粒子群优化算法可以求解气动布局参数对飞行性能的推荐域,根据指标要求或者原准机型得到一组可以接受的飞行性能目标,求解直升机气动布局参数的推荐域,使得推荐域内气动布局参数组合的对应飞行性能不低于飞行性能目标,进而配合其它限制完成参数优化。根据这一方法对算例直升机的主旋翼轴、短翼和水平尾翼的气动布局参数进行分析,给出其对飞行性能的推荐域解集,表明该方法的有效性,并总结这些气动布局参数推荐域边界的主要规律。
The helicopter parameters take part in performance. By giving the boundary of accepta- ble performance, the multi - object particle swarm optimization was used to calculate the feasible zone of parameters which performance would meet the requirement inside. The method was going to be used to calculate the sample helicopter. The feasible zones of main rotor shaft, wing and tail plane were given. The laws of these feasible zones were also summarized.
