Multi-material transportation aircraft and control method thereof

Abstract

The invention discloses a multi-material transportation aircraft and a control method thereof. The aircraft comprises an aircraft body, a material storage device, a material protection box, a rotating disc module and self-locking devices. A mounting platform is arranged at the bottom of the aircraft body, and the material storage device is mounted on the mounting platform; the material storage device comprises a plurality of storage bins, and a plurality of material protection boxes are arranged in each storage bin; the self-locking devices are arranged in the storage bins and used for locking the material protection boxes, and accurate feeding of materials is achieved. The rotating disc module comprises a rotating disc, a steering engine, a rotating shaft and a coupler; when the aircraft arrives above the target site, the steering engine drives the rotating disc to rotate, so that the opening of the rotating disc is just aligned with the position of a certain storage bin, the corresponding self-locking device is triggered to be closed, the corresponding material protection box falls from the opening of the rotating disc under the action of gravity, and material feeding is realized. The precision and success rate of material feeding are improved, and the number of materials carried in one-time flight is increased.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a multi-material transport aircraft and a control method thereof. Background technique [0002] At present, UAVs are more and more widely used in civilian fields, such as aerial photography and delivery. A multi-rotor UAV is a special unmanned helicopter with three or more rotor shafts. It is rotated by an electric motor on each shaft to drive the rotor, thereby generating thrust. The collective pitch of the rotors is fixed, not variable like normal helicopters. By changing the relative rotational speed between different rotors, the size of the single-axis propulsion can be changed, thereby controlling the trajectory of the aircraft. [0003] Multi-rotor drones have strong controllability, can take off and land vertically and hover, and are mainly suitable for low-altitude, low-speed missions that require vertical take-off and landing and hovering;...

AI Technical Summary

Problems solved by technology

[0004] Most of the disaster relief and cargo drones now use fixed-wing drones or manned helicopters instead of multi-rotor drones. A big reason is that multi-rotor drones cannot effectively carry materials. UAVs are mostly used for aerial photography, detection and other tasks

However, the accuracy of the delivery of materials by fixed-wing UAVs and the amount of materials that can be transported at one time are limited, and manned helicopters consume too much resources. Therefore, a multi-material transport aircraft and control method are provided. UAVs are used in emergency rescue, disaster relief, and cargo handling work
