随着航天型号向信息化、集成化、智能化方向发展,航天软件已经成为航天型号研制必不可少的组成部分,直接关系到型号飞行试验的成败。近年来,通过对国内外航天型号研制过程中的994个技术风险案例进行统计分析,结果显示其中设计类风险461个(占比46.4%),为排序第一的风险类别,而设计类风险中 With the development of aerospace models towards informatization, integration and intelligence, aerospace software has become an indispensable part of the development of aerospace models, which is directly related to the success or failure of model flight tests. In recent years, the statistical analysis of 994 technical risk cases in the development of aerospace models at home and abroad shows that there are 461 design risk types (accounting for 46.4% of the total), which are the first-ranked risk categories. In the design risk category
