摘要
扇翼机兼具固定翼飞机和直升机的优越性能,通过在厚机翼前缘嵌入横流风扇代替传统固定机翼,可同时提供升力和推力,并会附加一定的低头力矩,使得扇翼机纵向高度控制和姿态控制存在强耦合。独特的动力结构使扇翼机具有较高的静稳定性,但扇翼机机载空间有限,基于此提出基于角速率陀螺的扇翼机简化配置控制技术研究,并分析了控制系统的频域和时域特性。通过非线性仿真对比分析,验证了简化配置控制方案的有效性,且纵向简化配置相较于全配置更适合扇翼机纵向的飞行控制。
FanWing has the advantages of both fixed-wing aircraft and helicopters.It replaces the conventional fuselage with an extremely thick wing with partially embedded,distributed cross-flow fans that could offer lift,thrust,and the additional pitch-down moment.The unique dynamic structure offers FanWing high static stability with a limited airborne space.Based on the characteristics,research on the simplified configuration control technology of FanWing based on the angular rate gyroscope is proposed.The frequency domain and time domain characteristics of the control system are analyzed.The effectiveness of the simplified configuration control scheme is verified by comparison and analysis of the nonlinear simulation.And the longitudinal simplified configuration is more suitable for the longitudinal flight control of FanWing than the full configuration control.
