摘要

摘要: 研究了涡轴发动机/旋翼一体化优化控制问题, 分析了直升机旋翼需用功率与涡轴发动机工况的关系, 旋翼转速、旋翼总距、纵向周期变距及横向周期变距对旋翼需用功率的影响.以最小旋翼需用功率为目标函数, 用线性规划算法进行发动机/旋翼性能寻优.进行了巡航状态下变旋翼转速的涡轴发动机优化的数字仿真实验, 仿真结果表明在巡航状态应用变旋翼转速的涡轴发动机优化, 可以降低油耗1.5%～5.5%, 同时降低涡轮温度4.4～16℃, 具有实际应用价值.

Abstract: The integrated optimization of turboshaft engine/rotor was studied to analyze the relationship between power requirement of helicopter and the operating status of turboshaft engine,and the effect of the rotor revolutions per minute(RPM),collective,longitudinal cyclic and lateral cyclic on the power requirement of the helicopter.Linear programming(LP) was used to optimize the turboshaft engine/rotor performance by taking the minimum power requirement of rotor as the objective function.Meanwhile,digital simulation test was conducted for optimization of turboshaft engines with variable rotor speed in cruising state.The simulation results show that,the fuel consumption could decrease by 1.5%⁵.5% and the turbine temperature decrease by 4.4¹6 ℃ after optimization of turboshaft engine with variable rotor speed in cruising state.
