为了实现直升机巡航飞行时最经济运行,基于某型常规布局直升机,建立巡航阶段需用功率目标函数,以飞行稳定性与操纵安全性指标作为约束条件,利用遗传 序列二次规划( GA-SQP )混合优化算法,对直升机巡航阶段实现最低需用功率的最优旋翼转速进行优化求解。实验结果表明,该方法得到的最优旋翼转速能够有效降低整机需用功率,优化算法得出的最优转速曲线对巡航状态下旋翼转速的变化方向具有一定参考意义。

Helicopter Rotor Speed Optimization Control Based on Hybrid Optimization Algorithm

In order to realize the most economical operation of helicopter in cruise flight , based on a certain type of conventional layout helicopter , a rotor required power objective function in cruise phase is established.Taking flight stability and handling safety indexes as constraints , the optimal rotor speed to achieve the minimum required power in helicopter cruise phase is solved by using GA-SQP hybrid optimization algorithm.The experimental results show that the optimal rotor speed obtained by this method can effectively reduce the required power of the whole helicopter , and the optimal speed curve obtained by the optimization algorithm has a certain reference significance for the change direction of rotor speed under cruise state.
