Three-dimensional power aircraft

Abstract

The invention relates to the field of aircraft design, in particular to an aircraft. The directions of power mechanisms of the aircraft can be independently changed, and the aircraft further can three-dimensionally fly. The aircraft comprises a central body (1), a first framework (2), a second framework (3), propellers (4), motors (5), bearings (6) and hollow shafts (7). Flight control assembliesfor controlling the aircraft are arranged inside the central body (1), two sides of the central body (1) are connected with the first framework (2) by the hollow shafts (7) and the bearings, the motors (5) and the propellers (4) are fixed to two sides of the first framework (2), and the two sides of the first framework (2) are connected with the second framework (3) by the hollow shafts (7) and the bearings (6). Compared with existing aircrafts, the aircraft has the advantages that the aircraft is novel in structure and reasonable in design; the aircraft can fly towards optional directions under the condition that only the power directions are changed, the problem of incapability of three-dimensionally flying without change of the directions of central structures of all existing aircraftscan be solved, and the flight performance of the aircraft can be greatly improved.

Description

technical field [0001] The invention relates to an aircraft, in particular to a three-dimensional powered aircraft whose power output direction can be changed in any three-dimensional direction. Background technique [0002] All aircrafts today have similar structures, and the main body of the aircraft is separated from the power structure and the direction change is not complete. [0003] A helicopter is essentially another aircraft different from an airplane, and its thrust, lift, and control are far behind those of an airplane. The outstanding feature of the helicopter is that it can do low-altitude (a few meters above the ground), low-speed (starting from hovering) and maneuvering flight with the same nose direction, especially vertical take-off and landing in a small area. [0004] The three-axis aircraft is a hovering aircraft that can stabilize its own flight and use the least number of motors. There is no more redundancy, and it can stably implement horizontal contr...

AI Technical Summary

Problems solved by technology

[0004] The three-axis aircraft is a hovering aircraft that can stabilize its own flight and use the least number of motors. There is no more redundancy, and it can stably implement horizontal control in three directions with an angle of 120 degrees. It can quickly control the vertical direction. reach position, its flight stability is weak compared to other propeller aircraft

Compared with quadcopters, hexacopters and octocopters have more redundant motors, which enhances its stability so that the aerial photography function can be better realized, and relatively loses functions such as flexible flipping

[0005] The quadrotor UAV changes the rotor speed by adjusting the speed of the four motors to achieve the change of lift force, thereby controlling the attitude and position of the aircraft; since the aircraft realizes the lift force change by changing the rotor speed, this will lead to its power instability, so Need for a control method that ensures long-term stability; the quadrotor is a six-degree-of-freedom vertical take-off and landing machine, making it ideal for flying in static and quasi-static conditions

Multi-rotor drones are slow, have poor wind resistance and airflow capabilities, and are easy to deviate from the route and change their flight attitude in strong winds and turbulence

[0006] Although aviation technology has been able to adapt to most weather conditions, wind, rain, snow, fog and other weather conditions will still affect the safety of aircraft takeoff and landing
