Detachable tailstock type vertical take-off and landing unmanned aerial vehicle

Abstract

The invention provides a detachable tailstock type vertical take-off and landing unmanned aerial vehicle. Wings and a fuselage can be detachably assembled. The wings and the fuselage can form two overall arrangement forms. According to the X-shaped overall arrangement form, two pairs of wings are mounted on the fuselage and are bilaterally symmetrical, and each pair of wings is of a longitudinal symmetry structure; and the included angle between the wings in each pair is 120 degrees, and the four wings form an X shape. According to the Y-shaped overall arrangement form, three wings are mounted on the fuselage, the included angel between every two adjacent wings is 120 degrees, and the three wings form a Y shape. The unmanned aerial vehicle of the X-shaped overall arrangement form is suitable for long-distance flight under a wind-free condition. The vertical take-off and landing unmanned aerial vehicle of the Y-shaped overall arrangement form is suitable for short-distance flight under a lateral wind condition. According to the detachable tailstock type vertical take-off and landing unmanned aerial vehicle, the structure is simple, and control is easy; and since the wings and the fuselage are connected detachably, the unmanned aerial vehicle is suitable for different occasions, singular problems in a transition mode are avoided, and long endurance and long-distance flight can be achieved.

Description

technical field [0001] The invention belongs to the field of aircraft structure design, and relates to the shape design, aerodynamic analysis and controller design of the aircraft. Background technique [0002] A vertical take-off and landing vehicle (VTOL) is precisely defined as one capable of taking off / landing at zero speed, capable of hovering, and capable of horizontal flight in the manner of a fixed-wing aircraft. Compared with traditional aircraft, vertical take-off and landing aircraft are independent of the runway and have the advantage of being able to hover. Compared to traditional helicopters, VTOL vehicles have a much higher forward flight speed and have a greater range. Because of these advantages, the vertical take-off and landing aircraft is especially suitable for occasions that need to hover or have special requirements for the take-off and landing site. [0003] Vertical take-off and landing drones can be roughly divided into three types, one is a tilt-...

AI Technical Summary

Problems solved by technology

First of all, the transition mode involves a pitch angle change of more than 90 degrees, which will bring singular problems. In addition, the aerodynamic model of the UAV will change drastically during the transition flight process, which will bring serious problems to the design of the controller during the entire flight process. certain difficulty
