Flight Dynamics Modeling and Flight Performance Analysis of Variable Rotor Speed and Variable Diameter of Tilt-Rotor Aircraft

Wu, Rong / Zhang, Xiayang / Zhao, Qijun / Wang, Bo

To study the influence of rotation speed and rotor diameter on the control characteristics and flight performance of a tilt-rotor aircraft, a flight dynamics model and a required power calculation model of the tilt-rotor were established. Trim analysis was carried out under three typical flight modes, and the change of the required power was further analyzed. The results showed that as the rotor speed/diameter increased, the collective pitch and cyclic pitch of the rotor and the pitching angle of the fuselage decreased, and the deflection angle of the elevator increased. As the rotor speed increased, the required power of the tilt-rotor aircraft increased. In helicopter mode, the required power decreased with increasing rotor diameter, while in fixed-wing mode, the required power increased with increasing rotor diameter.
