Abstract: Scenario as an important bridge between the aircraft designers and uses, its complexity rises ceaselessly with the systematic development of aircraft trend. Designers and users need more intuitive, more understandable, and more efficient methods in scenario description and construction, so as to have a unified "common context" for the design and application of related applications. Based on the analysis of typical scenario application, the definition and main characteristics of Virtual Open Scenario (VOS) oriented to system of systems oriented design and application are proposed, the Multi-Dimensional Mapping (MDM) of scenario elements and construction process of VOS are proposed. In view of the main links in the process, a two-layer evaluation matrix for tailoring MDM and open encapsulation from MDM instances to components are proposed, and a support system architecture that supports VOS composition and interaction is discussed to flexibly build a virtual open scenario family that can reflect different concerns. Finally, a virtual open scenario family construction case for multi-aircraft maritime search and rescue system is presented, which realizes the description of search and rescue helicopter scenario from global and local perspectives and verifies the effectiveness of the proposed concept and method.

Key words: virtual open scenario, system of systems oriented design and application, multi-dimensional mapping, support framework, two level evaluation matrix
