| 摘 要： | 针对旋翼飞行器本体微型化的瓶颈问题,介绍了一种新型非对称变距结构,研究并分析了其变距机理和控制特性,并对变距关键件弹性连杆进行了弹性力学分析和有限元计算,得到桨距变化与旋翼主轴电机的输出扭矩成线性关系.再通过光电传感器和位置控制码盘检测旋翼所在相位,以便在预期变距相位改变电机转速,从而实现微型旋翼飞行器各向机动飞行.

| Abstract: | A novel asymmertrical pitch system faced to rotary wing MAV is introduced. The pitch mechanism and control characteristics are studied and analyzed. Because the deformation of elasticity link is key to generate the blade pitch, it is analyzed and caculated by elasticity finite element method. And the results illustrate the linear relationship between blade pitch angles and the output torque of the motor. The phase of rotary wing can be measured by the photoelectric encoder. So the flight to all directions can be carried out when the motor is accelerated at expectant phase. |
