Abstract:

Dynamic virtual prototype(DVP) of aircraft focuses on studying dynamics characters. Based-on Modeling and Simulation(M&S) of each subsystem, the aerodynamic characters, control system, engine characters, flight performance and flying qualities are analyzed, tested and evaluated in the development environment and run environment. DVP supports the requirement analyzed, program demonstration, conceptual design and preliminary design. Pilot can achieve virtual flight testing with Human-in-the-Loop. Combat effectiveness is certified and analyzed in the confrontation environment of weapon platform system. Multidiscipline design optimization(MDO) of aircraft is achieved in the collaborative environment of DVP.

Key words: virtual prototype, simulation based design, virtual flight testing, combat effectiveness, multidiscipline design optimization
