为确保结冰条件下的飞行安全并充分发挥飞机性能,提出了一种最优边界保护方法.以关键参数及其变化速率为控制对象,在分析最优边界保护下关键参数及其变化速率特性的基础上,选取调节量和调节时机作为调节参数,并构建这2个调节参数最优值之间的解析关系.针对机翼失速问题,给出动态飞行边界的确定方法,最终通过计算实现结冰条件下的最优边界保护.仿真结果表明,该方法行之有效,为结冰条件下的飞行安全研究拓展了新的思路.
In order to ensure flight safety under icing conditions and give full play to aircraft performance, an optimal boundary protection method is proposed.With the key parameters and their rate of change as the control objects, the key parameters and the rate of change under the optimal boundary protection , The adjustment amount and the adjustment timing are selected as the adjustment parameters and the analytic relationship between the optimal values of the two adjustment parameters is established.Aiming at the problem of the wing stall, the method of determining the dynamic flight boundary is given and finally the calculation of the knot The optimal boundary protection under ice condition.The simulation results show that this method is effective and extends the new ideas for flight safety research under icing condition.
