航天工程系统技术成熟度评估方法研究

航天工程的技术支持系统十分复杂,单一技术成熟度评估方法不能有效解决系统整体的成熟度评估问题。文章以系统论、集成方法为指导,基于技术系统结构分解,从基本的单机构成要素为起点进行技术成熟度评价,考虑了不同系统层次的技术接口问题,进而按照逐层集成的方法完成一项航天工程整体技术系统成熟度的评估工作。这种评估方法具有系统性、综合性特点,能够满足航天工程整体技术系统成熟度评估的实际应用需求。

Research on System Technology Readiness Level Evaluation Method of Space Engineering

The technical support system of an aerospace engineering is very complex. So TRL （technology readiness level） of a whole system can not be effectively assessed by a single technol- ogy TRL evaluation method. By using system theory and integration method, the TRL evaluation is discussed from the basic unit elements based on technique system structure decomposition. The technical interface problems of different system level are considered, then an aerospace engineer- ing system TRL assessment is completed according to the layer-by-layer integration method. The assessment method has such systematic and comprehensive characteristics that it can meet the practical application demand for the system TRL evaluation of an aerospace engineering.
