摘要
滚翼机是一种由摆线桨驱动的新型无人飞行器,具备低噪声、高效率、高机动性的特点。在验证机的滚转操纵试飞过程中,发现滚翼机存在明显不稳定现象。通过建立滚翼机的动力学模型并进行仿真,研究总体参数对其滚转稳定性的影响。仿真结果表明,导致滚翼机不稳定的主要原因是摆线桨产生的陀螺力矩引起的三轴力矩耦合。
Cyclogyro is a kind of new UAV propelled by cycloidal propellers with extremely low noise, high efficiency and high maneuverability. Flight test of roll step-input shows that the cyclogyro suffers from poor stability. The dynamic model of cyclogyro was established and the simulation was done to figure out how the configuration parameters affect the rolling stability. Simulation results show that the gyroscop- ic effect of cycloidal propellers leads to the coupling of the moments about three axis, which deteriorates the stability of cyclogyro.
