    摘要:

    提出了一种从发动机引流发电的原位电能获取技术,即从动力充沛的发动机处引流高压燃料,经能量转换装置发电后返回发动机。该技术可以大幅度减轻电源系统质量。以1 200 kN液氧煤油发动机应用为例,研制了35 MPa恒速发电机和整流变换的轻质化原理性样机,搭建了驱动双摆电静压伺服机构的试验系统。测试结果表明:该系统可以满足额定270 V、峰值40 kW的伺服系统高压大电流瞬时用电需求,也可以满足28 V一般箭载电子设备用电需求。该技术有望为未来运载火箭设备多电化/全电化提供一种轻质化、高安全性、大功率的电源方案。

    Abstract:

    This paper proposes an in-situ electric energy acquisition technology for power generation by drawing propellant from a rocket engine. The high-pressure fuel is drained from the engine with abundant power, and then returns to the engine after power generation by the energy conversion device. This technology can greatly reduce the weight of the power supply system. A 1 200 kN liquid oxygen kerosene engine is taken as an example, and a lightweight principle prototype of 35 MPa constant speed generator and rectifier transformation is developed. A test system for driving a two DOF electro-hydrostatic actuator system is built. The test results show that the system can meet the instantaneous power demand of the servo system with the rated high voltage of 270 V and the peak power of a high current of 40 kW, and also meet the power demand of the 28 V general rocket borne electronic equipment. This technology is expected to provide a power supply scheme with lightweight, high safety and high-power for multi electrification / full electrification of launch vehicle equipment in the future.
