Design of Tiltrotor Flight Control System Using Optical Control

Tiltrotor can flight both airplane mode and helicopter mode by changing the propulsion thrust vector via angle of nacelle. Therefore tiltrotor has performance of vertical and short take-off and land (V/STOL), multi-purpose aircraft with excellent high-speed cruise. However, it is very difficult to design the flight control system for transforming the flight mode because both thrust vector and aerodynamic force are used. First the model of the tiltrotor is given, and then the method of optical control is present to design the flight control system. The power of propeller constant conversion scheme that is supporting the power of the propeller is constant while tiltrotor coverts the flight mode has been interpreted. Finally the flight control system is simulated and the simulation results have been proved that the flight control system is feasible.
