Analysis of Flight Dynamics Characteristics of Tilt Quad Rotor with Partial Tilt-Wing

论文摘要

The aerodynamic model of propeller,wing,fuselage and vertical tail are established for the tilt quad rotor（TQR）with partial tilt-wing,and then the flight dynamic model is established. Based on the six-degree-of-freedom equation and the small disturbance linearization assumption,the trimming and stability of the tilt quad rotor with partial tilt-wing and the tilt quad rotor without tilt-wing are analyzed. The results show that in the hovering state,due to the existence of tilt-wing,the propeller wake reduces the downwash on the wing,thereby reducing the vertical weight gain of the aircraft. It is beneficial to increase the endurance time and improve the endurance performance. The transition corridor of the TQR with tilt-wing is narrower than that of the TQR without tilt-wing,but the transition corridor of TQR with tilt-wing still has a large space for design. Furthermore,the stability analysis shows that the Dutch roll damping ratio is larger,and in other modes the aircraft has a certain stability. The manipulation response analysis shows that in the transition mode the lateral-directional coupling is strong.
