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-...
