Abstract

The invention discloses a transformable four-rotor aircraft. The transformable four-rotor aircraft comprises an aircraft body, the opposite two sides of the bottom of the aircraft body are symmetrically provided with undercarriages, the top of the aircraft body is provided with a steering engine driving module, the steering engine driving module is provided with an aircraft arm and an aircraft armconnecting rod, and both ends of the aircraft arm as well as the aircraft arm connecting rod are provided with electric propeller modules. During flight, by rotatingly lifting a pair of propellers up, the transformable four-rotor aircraft can be switched to a coaxial propeller reversed flight mode. Therefore, the transformable four-rotor aircraft can solve the problem that a traditional four-rotor aircraft cannot pass through narrow areas due to large body size.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and relates to a deformable quadrotor aircraft. Background technique [0002] Multi-rotor UAV is a kind of aerial robot, which belongs to the category of special robots. It has the advantages of vertical take-off and landing, hovering in the air, high maneuverability and low cost. It is widely used in disaster search and rescue, military reconnaissance, map surveying and other fields. [0003] However, usually the quadrotor aircraft only uses four degrees of freedom control input to complete six degrees of freedom movement, which is a typical underactuated system with limited flexibility, especially when flying in a narrow space, the airborne reconnaissance and passing performance are greatly affected. Great impact and limitations. In recent years, the above-mentioned problems for quadrotor aircraft have received a lot of attention. [0004] Chinese patent (name: a portable fol...
