一种基于需求工程思想的民用飞机需求确认方法

A Method of Civil Aircraft Requirements Validation Based on Requirements Project Principle

依据民用飞机在产品开发过程中需求如何确认的现实需求,定义了一种基于需求工程思想的民用飞机需求确认的方法。该方法一方面引入了需求工程的思想,一方面在不破坏原有设计要素的前提下,同时利用设计方案作为两者沟通、融合的载体,有效实现了"需求是牵引,设计是根本"的现代民机产品开发理念。该方法和流程在民机型号的概念设计工作中得到应用,取得了较好的实践效果。为了能够对相关的工程设计工作提供可参考和借鉴的经验,以飞机起飞场长为例,对该需求的确认过程进行了详细剖析,进一步阐述这种设计方法的关键点和核心思想。

A method of requirements validation is developed and defined to meet the needs of civil aircraft re- quirements validation in product development. Based on requirements project principle, this method will not affect the conventional design elements, and can effectively connect the requirements with design. It realizes the modem civil aircraft development concept, which is ＂requirement is the origin, design is the basis＂. So far, the method has been successfully applied in civil aircraft aircraft development in China. Taking takeoff field length as an example, the validation process and the validation method of the requirements are detailed introduced in the study, with the hope of providing the experiences to other civil aircraft product design.
