大中型液体运载火箭水平起竖与发射技术

Erection and Launch Technology of Large and Middle Launch Vehicle

未来大量中低轨商业卫星的发射任务对大中型运载火箭提出了快速测发的技术需求。地面发射支持系统针对CZ-8火箭需求,在传统运载型号已有技术的基础上,重点开展了箭体整体水平组装及起竖对接技术、快速智能测发技术的研究,旨在进一步提升火箭发射任务效率、简化发射场设施、降低发射成本。以箭体水平组装设备、整体转运起竖对接设备、智能供气系统为切入点,对相关技术进行了阐述,此外,还提出了吊具、支架车两种水平组装方案。对整体转运起竖对接精度影响因素进行了分析,并介绍了起竖托架的刚度提升方法。介绍了智能供配气总体方案、智能减压阀技术、供配气设备故障诊断技术。

Based on the huge requirement of LEO or MEO business satellite launch mission,responsive launch technology for large or middle launch vehicle is badly needed.According to the requirements of Long March-8,land-launched supporting system focus on horizontal assembly and erection technology,responsive and intelligent launch technology,which can improve the efficiency of launch mission,simplify the equipment of launch site,and save launch cost.The study mainly elaborates horizontal assembly equipment,erection equipment,intelligent gas supply system.Two horizontal assembly schemes of spreader and bracket car are introduced.The factors that affect the accuracy of erecting and butting of the whole transport are analyzed,and the method of raising the rigidity of the erecting bracket are given.The general scheme of intelligent gas supply and distribution,intelligent pressure reducing valve technology and fault diagnosis technology of gas supply and distribution equipment are introduced.
