针对无动力投放模型自由飞试验中,由于受载机螺旋桨滑流影响,模型与载机分离后发生滚转,难以保证水平飞行的问题,根据无动力投放模型自由飞试验不同阶段的飞行特点开发了专用控制律,具备直接链、投放控制、失速尾旋三种控制模态。论述了控制律的设计过程,以及在模型自由飞试验中的应用情况。试飞结果表明该控制律很好地解决了模型与载机安全分离的问题和大迎角水平飞行控制问题,提高了模型试验动作精准度。
In the free-flight test of non-powered delivery model, due to the influence of the slippery of the loader propeller, the model and the carrier are separated and rolled, which makes it difficult to ensure the horizontal flight. Based on the flight characteristics of different stages of the free-flight test A special control law, with a direct chain, put control, stall spin three control modes. The design process of control law and its application in free-fly test of model are discussed. The test results show that the control law solves the problem of safety separation between the model and the aircraft and the flight control problem at high angle of attack, and improves the precision of the model test.
