摘要
超重-星舰(Super Heavy-Starship)运输系统是美国太空探索公司(Space Exploration Technologies Corp.,SpaceX)提出的两级完全可重复使用重型运载火箭.超重-星舰运输系统广泛应用机构技术以实现火箭的连接分离、气动控制、着陆缓冲等功能,同时采用高压冷气等取代传统火工品作为动力源.针对超重-星舰运输系统的着陆缓冲机构、栅格舵机构、阻力舵机构、级间分离机构、气驱机构,阐述机构组成、工作原理、设计思路、优缺点,总结SpaceX公司机构技术的创新点,分析中国运载火箭机构技术在研制及应用方面的差距和不足,并提出相应的发展建议.
Abstract
Super Heavy-Starship is a two-stage fully reusable heavy-lift launch vehicle proposed by Space Exploration Technologies Corp.(SpaceX).In Super Heavy-Starship,mechanisms are widely utilized to implement various functions of the launch vehicle,such as connection,separation,aerodynamic control and landing shock absorption.In addition,traditional pyrotechnics are replaced by high-pressure cold air as power source of mechanisms.Focusing on the landing shock absorption mechanism,grid rudder mechanism,flap rudder mechanism,stage separation mechanism,and pneumatic mechanism of Super Heavy-Starship,the mechanism composition,working principle,design ideas,merits and demerits are clarified.The innovation points of SpaceX's mechanisms are summarized.Furthermore,the gaps and deficiencies in the development and application of launch vehicle mechanisms in China are analyzed,and corresponding suggestions are put forward as well.
