一、引言航天产品精密复杂、协作配套多,而且由于其政治、社会影响大,有的还涉及人身安全,这些特点决定了必须严格控制设计更改,以及尽可能减少更改带来的危害和不利影响。航天企业经过几十年的摸索、完善,逐步形成了一套完整地控制设计更改的方法,即“技术状态更改控制要求”。本文重点叙述技术状态更改控制在航天企业是如何实施 I. INTRODUCTION Aerospace products are complex and complex, and because of their political and social impact and their personal safety, these characteristics determine that the design changes must be strictly controlled and the hazards and adverse effects caused by the changes minimized . Aerospace companies after decades of exploration, improvement, and gradually formed a complete set of methods to control design changes, that is, “the state of the art to change control requirements.” This article focuses on how technology status change control is implemented in aerospace companies
