基于DoDAF的飞行试验体系需求建模方法

Modeling method of flight test requirements based on DoDAF

飞行试验集科学性、实践性、风险性、复杂性于一体,现有依据经验的飞行试验体系需求确定模式,其规范性和科学性较差。结合飞行试验特性,在美国DoDAF2.0的基础上,提出一种基于模型的飞行试验体系需求建模方法,将用户要求转换为体系的功能需求、任务需求和系统需求,并围绕这些体系需求确定需求建模框架。结合某A型民机飞机性能要求从功能需求视图、业务活动视图、业务系统视图等视角进行需求建模,验证所提方法的可行性。

The flight test is a scientific,practical,dangerous,and complex process,and the current method of determining flight test requirements based on experience is rather unscientific.Combined with the characteristics of flight tests and based on DoD architectural framework 2.0,this paper proposes a model-based requirement modeling method for a flight test system,which converts user requirements into functional,task,and systematic requirements of the system.Based on these requirements,this paper determines the requirement modeling framework.Modeling needs from capability viewpoint,operational viewpoint,and systems viewpoint are used to confirm the method's viability along with the performance requirements of a civil aircraft.
