中国新一代中型运载火箭总体方案及发展展望

长征七号（代号CZ-7）运载火箭是为了满足中国载人空间站工程货运飞船发射任务而全新研制的新一代无毒无污染中型运载火箭。在空间站运行阶段，CZ-7火箭可满足货运要求并减少年发射次数，有利于降低空间站的维护成本，便于发射任务的组织实施。CZ-7火箭对未来主战场卫星发射任务具有良好的适应性，是新一代中型运载火箭系列的基本型，通过货运飞船和主战场卫星的发射可靠性子样积累，后续可用于发射载人飞船。2016年6月25日，CZ-7运载火箭成功完成了首次飞行试验。对CZ-7火箭总体方案进行了介绍，并对新一代中型运载火箭的发展做了展望。

General Scheme and Development Prospects for New Generation of Chinese Medium Launch Vehicle

Long March-7(CZ-7), as a new generation of medium and basic launch vehicle, with the design concepts of non-toxic and non-polluting , is developed for the purpose of launching a cargo space-flight to China space station. In the space station operation stage, CZ-7 meets the requirements of ensuring the freight transport while reducing the launch missions to reduce the maintenance cost and optimizing the organizational process. Based on the accumulation samples for the services of launching cargo space-flights and satellites, CZ-7 is adaptive to the mainstream satellites launch missions in the future with its characteristics of serialization and continuous optimization. CZ-7 is expected to launch a manned spacecraft in the future. CZ-7 performed its maiden flight successfully with all missions completed in 25th June, 2016. This paper presents a general review of CZ-7 in regard to the general scheme and provides references for the development prospects of medium launch vehicle series in China.
