深入研究了飞行品质规范中滚转振荡指标的物理意义,探讨了以侧滑相位描述滚转振荡指标的机理,分析了影响滚转振荡指标边界的三个因素。针对再入无人飞行器各飞行阶段,分析了滚转振荡指标的适用性。最后,基于方向舵交叉控制可以减小滚转速率振荡幅值比的控制策略,针对再入无人飞行器对滚转振荡指标的边界进行了初步拓展,为再入无人飞行器飞行品质指标的制定提供了一种思路。
The physical meaning of tumbling oscillation indices in flight quality specifications is studied in depth. The mechanism of tumbling oscillation indices is described based on the side slip phase. Three factors that influence the boundary of tumbling oscillation indices are analyzed. For each phase of reentry UAV flight, the applicability of tumbling oscillation index is analyzed. Finally, based on the rudder cross control, the control strategy of reducing the ratio of the oscillation rate of the roll rate can be reduced. The boundary of the roll oscillation index is further expanded for the reentry UAV to provide the flight quality index for reentry UAV A way of thinking.
