Problems solved by technology

[0004] The tail seat UAV can indeed overcome some deficiencies in the take-off and landing of the previous UAV. Because the tail seat structure supports the upright body, there is actually a problem related to stability: the difference between the longitudinal length of the body and the structural size of the tail seat. Therefore, the length of the airframe is limited, and flight stability, maneuverability, load loading, lateral air resistance, airframe size, maneuverability during vertical take-off and landing, and ability to choose a landing site are weak. insufficient

Abstract

A method of achieving vertical take-off and landing of an existing unmanned airplane includes a core method of installing a power turning device on an engine, an auxiliary method of changing the installation position of the engine, and an auxiliary method of employing an inverted-V-shaped lower double-inclined empennage and installing a support wheel on lower end of the empennage. By means of the method, under a horizontal status of an airframe of the existing unmanned airplane, a propeller on the nose of the airframe is tilted towards y axis, and when the included angle between the propeller and the airframe is 90 degrees, the nose of the airplane is pulled up, wherein the propeller is vertical to the y axis always to enable the airframe to be in a vertical status. The propeller pulls up the airframe to achieve the vertical take-off and landing of the unmanned airplane. During landing, when the vertical airframe slowly falls until the support wheel is landed, the pulling force of the propeller is reduced and a downward gravity is generated in the nose, and at this time, the propeller is rotated to the y axis to control the nose to slowly fall until a nose landing gear is landed to achieve landing.

Description

Technical field: [0001] The invention relates to a take-off method of an unmanned aircraft in the aviation field, in particular to an existing vertical take-off and landing method of an unmanned aircraft. Background technique: [0002] When the currently used unmanned aircraft take off, the small-sized unmanned aircraft adopts the hand-throwing take-off method, and the larger-sized unmanned aircraft uses orbit and rocket boosting to achieve take-off. Large unmanned aircraft need a runway to achieve take-off. When landing, the fences, parachutes, and runways are used to achieve landing. This method of take-off and landing brings a lot of inconvenience to the use of drones, and also limits the scope of use of unmanned aircraft. [0003] For these deficiencies in the take-off and landing of unmanned aircraft, the vd200 tail seat UAV (developed by AVIC Chengdu) is equipped with a tail seat structure at the tail of the fuselage, so that the body is in a vertical state with the no...
