航空航天飞行器交互设计系统(AVID)是用于航空航天飞行器方案设计和初步设计的一种计算机辅助设计系统。AVID系统是由任务要求和飞行器布局不断变化的、成熟的方案设计环境中的几种设计方法发展而成的。基本的AVID软件把单独的分析程序综合成可以单独执行或分组执行程序用以设计交互和参数研究的设计系统。已综合用于运载火箭设计的AVID系统的程序包括几何尺寸,空气动力,推进系统,飞行性能,质量特性和经费分析。
The Aerospace Interactive Design System (AVID) is a computer-aided design system for aerospace vehicle design and preliminary design. The AVID system has evolved from several design methods in mission-critical and aircraft layouts that are constantly changing in sophisticated program design environments. The basic AVID software synthesizes individual analysis programs into a design system that can execute programs individually or in groups to design interaction and parametric studies. Processes that have been integrated into AVID systems for launch vehicle design include geometry, aerodynamics, propulsion systems, flight performance, quality characteristics and funding analysis.
