| Abstract: | A mathematical model for calculating wing download of the tiltrotor aircraft in helicopter mode which covers hover and low speed forward flight is given according to the aerodynamic interaction effect of the rotor downwash flow on the wing. The rotor and wing interaction area model which considered the tiltrotor geometry scale, the tilt angle of the nacelle and the flight condition was the key element in this model. Then the model was utilized in the XV-15 tiltrotor aircraft flight dynamic mathematical model. The trim results showed that the rotor and the wing interaction download model of the tiltrotor aircraft was reasonable and effective. The wing download math model is suitable for the tiltrotor aircraft flight dynamic mathematical model. |
