Research On Application Of The Virtual Prototyping Technology To Tilt-Rotor Design

In this paper the research on the application of virtual design in the design of tilt-rotor. Make use of the commercial software to built the virtual prototyping, and the kinetic and dynamic behaviors of the tilt-rotor have been systematically simulated and studied. The main research include as follows:The virtual prototyping model has been built,and on the platform of ADAMS the dynamic property of virtual prototyping of V-22 1/5 scale model's rotor and wing system have been simulated and studied, according to the compared result to show the feasibility to analyze the tilt-rotor with the technology of virtual prototyping.On the basis of axial vortex theory, the aerodynamic performance of tilt-rotor model has been built, and using it to analyze the aerodynamic performance of XV-15, comparing to the actual data to prove the model's validity, finally studied the variety of aerodynamic performance relative to the variable rotor diameter.Variable diameter rotor is an effective method to improve the aerodynamic performance of tilt-rotor in both hover and cruise state. On the basis the research before, the variable diameter tilt rotor structure design has been finish, and in virtue of the technology of virtual prototyping to simulate and analyze the kinetic, dynamic and intensity property of it.
