Abstract

The invention provides a UAV layout with the least control configurations and belongs to the technical field of flight vehicle design and flight control. A UAV comprises a plane body, wings on both sides, engines on both sides and a stabilator, wherein the engines on the both sides are fixed under the wings on the both sides respectively, and the stabilator is fixed on the tail part of the plane body; and horizontal course control of the UAV is realized by the engines on the both sides of the plane body, and longitudinal control of the UAV is realized by deflection of the stabilator. The UAV layout provided by the invention has the beneficial effects that only one stabilator is disposed on a control pneumatic control surface of the UAV, so a resistance generation face is greatly reduced during UAV design and flight resistance is reduced without addition of an extra control execution mechanism; the least control surface is used for control, and the quantity of the control execution mechanism is minimized, so energy consumption generated from control can be reduced to a certain extent; and overall deflection of the stabilator is used, so steerage effects of control are increased as much as possible on the premise that a horizontal tail area is reduced and thus UAV control is more sensitive and effective.

Description

technical field [0001] The invention belongs to the technical field of aircraft design and flight control, and in particular relates to an unmanned aerial vehicle layout with minimum rudder surface configuration and a control method thereof. Background technique [0002] Most of the existing traditional fixed-wing UAVs use a combination of ailerons, elevators and rudders for flight manipulation and control of UAVs. In this method, rudder surfaces that rotate around the axis are respectively installed on the wings, vertical tail and flat tail of the drone to form ailerons, rudders, and elevators. When the aircraft is flying, the three rudder surfaces rotate around the axis to change the position of the wings and tail. The air pressure distribution generates the aerodynamic moment that makes the drone rotate around three different fuselage axes, realizes the change of the drone's attitude, and then controls the attitude and trajectory of the drone. [0003] However, this kind...
