新一代载人飞船试验船回收着陆系统产品保证工作实践

Executive Strategy and Practice of Product Assurance for Recovery and Landing System of New-Generation Experimental Manned Spacecraft

针对新一代载人飞船试验船回收着陆系统新技术多、产品组成复杂的技术特点,和一步正样管理、研制周期短的难点,在研制期间全面实施了产品保证工作。充分借鉴已有经验,以确保质量和可靠性为前提,以群伞气动减速和大载重无损着陆缓冲等新技术攻关为重点,构建基于时间、要素和程序3个维度的产品保证模型,将产品保证工作融入流程并纳入计划管理。按照"重点集中攻关,验证合理简化,研制阶段并行"的思路开展工作,高度关注分系统设计、生产、验证、总装等重要环节,通过技术风险识别与控制、产品差异化过程管理、关键生产过程加严管控、空投试验重点保证,确保返回舱安全返回、任务成功。对全新研制模式下回收着陆系统产品保证的实施策略和实践经验进行了探讨,可为其他回收着陆系统产品保证工作提供一定的参考。

Based on the technical characteristics and development difficulties of the recovery and landing system of our new-generation experimental manned spacecraft,product assurance is fully implemented in the whole procedure of its development.Drawing on referential experiences,the three-dimension product assurance being composed of time,element and procedure is established,which takes quality and reliability as promise and focuses on multistage closing of the cluster parachutes and airbag landing system of the massive spacecraft.A great attention to Recovery and Landing System’s design,manufacture,verification and assembly,and is integrated into developing processes to realize proper implement.The executive strategy and practice of product assurance for the recovery and landing system of our new-generation experimental manned spacecraft,such as how to identify and control the system’s technical risks,manage the product realization differently,control the key production process strictly,guarantee the airdrop test at all levels,etc,are described.Product assurance effectively guarantees the quality of the recovery and landing system of our new-generation experimental manned spacecraft,the paper discusses its executive strategy and practice experiences,which can also be used as a reference for other recovery and landing system’s product assurance.
