摘　　要：利用放射性元素α衰变发射高速粒子产生反推力,研究了的核能衰变的推进技术。考虑到α粒子的弱穿透性,运用面积遮挡的方式改变推力。采用超声电机实现α粒子推力薄膜的精确控制,针对直线型与环形超声电机设计了2种驱动方案,分别是旋转超声电机驱动光阑和直线型超声电机驱动对开式开关,详细描述了原理和结构,并对其矢量合成做了分析。In this paper,the propulsion technology of nuclear energy decay is studied by using radioactive elementαdecay to emit high-speed particles in order to generate counter-thrust.By considering the weak penetration ofαparticles,the area shielding method is used to change the thrust.Accurate control ofαparticle thrust film is realized by using ultrasonic motor.Two driving schemes are designed for linear and ring ultrasonic motors.The principle and structure are described in detail,and their vector synthesis is analyzed.
