Problems solved by technology

[0012] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a jet self-rotating disc aircraft capable of vertical take-off and landing and its working method, aiming at the inability of most fixed-wing aircraft to take off and land vertically and hover in the air, helicopters In order to solve the problems of limited flight speed and unstable flight of some dish-shaped aircraft, a jet self-rotating disk-shaped aircraft capable of vertical take-off and landing is designed. The take-off and landing process does not need to consider the space constraints of the site, it can take off and land freely, hover, climb, and has good stability in the high-speed spin flight state

specific Embodiment approach

[0048] The first is the attitude control mode of the aircraft. When the aircraft presses Figure 4 When rotating at a high speed in the clockwise direction, due to the friction of the annular bearing mechanism connecting the disc-shaped body 1 and the stator body 2, the stator body 2 will also spin at a high speed with the disc-shaped body. The deflection angle (clockwise) of the flow sheet will generate a counterclockwise torque acting on the stator body 2, which can be used to offset the ring bearing mechanism when the aircraft spins because the friction force acts on the stator body 2 in the direction of the pointer Torque, so as to ensure that the stator body 2 remains stationary or rotates at a very low speed relative to the ground; for the control mode of the pitching attitude of the aircraft, since the structure of the aircraft is symmetrical, such as Figure 5 , a number of control nozzles 17 are symmetrically distributed on the plane where the attitude control ring is...

Abstract

The invention discloses a jet self-rotation disc type aircraft capable of realizing vertical take-off and landing and a working method. The jet self-rotation disc type aircraft is formed by two parts of a disc type machine body and a stator machine body which can be used for bearing cargos, and mainly comprises a rotary disc machine body, a lift fan, jet engines, air inlets of the jet engines, air outlets of the jet engines, a lift fan hub, a gyrorotor type cargo compartment, a stator blade bar, a stator blade bar hub, an outer cartridge receiver of the stator blade bar, vector nozzles, flow deflectors and the like. According to the jet self-rotation disc type aircraft capable of realizing the vertical take-off and landing, designed by the invention, the jet self-rotation disc type aircraft adopts pneumatic layout with a blended wing body, not only has good pneumatic performance, but also has no need to consider limiting factors of place space during a take-off and landing process, is capable of freely taking off and landing, hovering and climbing, and has good stability under a high-speed self-rotation flying state.

Description

technical field [0001] The invention belongs to the technical field of aircraft, and in particular relates to a jet self-rotating disc aircraft capable of vertical take-off and landing and a working method. Background technique [0002] UAVs have become one of the hottest terms in the industry in recent years. UAVs have been widely used in aerial photography, express delivery, post-disaster search and rescue, data collection and other fields. In police force, urban management, agriculture, geology, meteorology, electricity, etc. , express delivery, surveying and mapping, plant protection, spraying pesticides, surveying and mapping, line inspection and other industries, drones are playing an increasingly important role. It is expected that the total consumption of the unmanned aerial vehicle market will increase exponentially in the future, and the growth potential of the commercial unmanned aerial vehicle consumption market is even greater, which is suitable for the applicat...
