随着国家对航天事业重视程度的不断加大,目前处于预研、在研、批生产的飞行器型号数量越来越多,但其研制模式仍按传统研制思路实施,所以呈现出型号任务规模越来越大、新技术越来越复杂、研制周期越来越短、质量要求越来越高、保障资源越来越困难等突出特点。 As the state attaches great importance to the aerospace industry, there are more and more aircraft models in pre-research, research and batch production. However, their research and development models are still implemented according to the traditional research ideas, so the scale of the model tasks The bigger the new technology is, the more complex the new technology is, the shorter the development cycle is, the higher the quality requirements are, and the more and more difficult the protection of resources is.
