Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings.

[0043] The present invention is a new diversion control method for a multi-rotor aircraft suitable for a turbofan engine, such as figure 1 , 2 As shown, the turbojet engine is used as the power source of the multi-rotor aircraft under the ducted fan (rotor) or in the air duct to install a deflector to form a new multi-rotor aircraft structure and control structure.

[0044] Preferably, a guide device is installed below each ducted fan (rotor) of the multi-rotor aircraft, and the guide device is made up of several (even number) guide plates. It can be installed in the air duct, and the flow guiding device forms a new multi-rotor aircraft structure together with the turbofan engine. Whether the deflector is installed in the duct or under the ducted fan (rotor), the pressure difference between the upper and lower sides of the ducted fan (rotor) can be controlled by adju...

Abstract

The invention discloses a new diversion control method for a multi-rotor aircraft suitable for a turbofan engine. Several (even number) deflectors are arranged in parallel at the same interval to form a deflector, which is installed below each ducted fan (rotor) of the multi-rotor aircraft or inside the air duct of the aircraft in the present invention, through the installation of the deflector A new type of multi-rotor aircraft structure is formed. According to the above aircraft structure, the change of the flight attitude of the aircraft will be realized by changing the angle of the deflector, forming a new control mode of the multi-rotor aircraft. The deflector realizes the adjustment of the attitude of the multi-rotor aircraft, but the large vertical lift of the aircraft still requires the turbofan jet engine to drive the main lift system—the ducted fan (rotor). The invention greatly improves the convenience and accuracy of multi-rotor aircraft attitude adjustment, is convenient to deploy, has great advantages in development cost and specific implementation, and has great application prospects.

Description

technical field [0001] The invention belongs to the technical field of multi-rotor aircraft, and in particular relates to a novel diversion control method for multi-rotor aircraft suitable for turbofan engines. Background technique [0002] The rotor UAV is a UAV with high-speed rotating wings as the power source, which can realize vertical take-off and landing, hovering, horizontal flight, inverted flight and ultra-low-altitude flight. It is suitable for use in small spaces or It is used in complex terrain environment, and its good flexibility is its main feature. The design of the UAV flight control system is the key and core to realize the autonomous flight of the UAV. The performance of the flight control system directly determines the flight performance and task completion of the rotor UAV. Therefore, the development of a lightweight, low-cost, and low-power flight control system suitable for multi-rotor UAVs has important theoretical value and engineering application ...
