液体火箭发动机自锁定机电伺服机构

A Self-locking Electro-mechanical Actuation System for Liquid-Propellant Rocket Engine

  • 摘要: 针对我国新一代运载火箭“长征八号”批量生产和“三平”敏捷发射的需求,提出了大推力液体火箭发动机自锁定机电伺服机构方案。采用自锁定模块,设计了紧凑的串联式模块化机电作动器结构和谐振抑制控制策略,并进行了试验研究。结果表明,该方案可满足长时间水平运输零位锁定需求,具备重力力矩下长时水平测试能力,可抑制液体发动机的低频谐振,适宜批量生产,为我国新一代中型运载火箭“长征八号”的研制工作提供技术支持。

     

    Abstract: A self-locking electromechanical actuation system to gimbal a high thrust liquid rocket engine is put forward to meet the demands of the batch production and the triplex horizontal preparation for an agile launching of China’s new generation launch vehicles. A self-locking module is designed, a tandem compact electro-mechanical actuator and a control algorithm to suppress structural resonance are adopted. Ground experiments are carried out. It is shown that, the requirements of a long term horizontal transportation, a horizontal testing to tolerate the engine gravity effect, the control of the low frequency resonance of a liquid engine, and easiness for batch production, shall all be satisfied, laying a good foundation to facilitate the development of the next generation medium-sized launch vehicle in China.
