Four-rotor aircraft rack

Abstract

The invention is applicable to the field of unmanned aerial vehicles, and particularly relates to a four-rotor aircraft rack which comprises a main rack body additionally provided with an undercarriage. The main rack body comprises four propeller structures which are distributed in an X-shaped array at unequal included angles; an electronic speed regulator is installed on the main rack body and used for acting on the propeller structures and regulating and controlling the rotating speed of the propeller structures through the electronic speed regulator, and an energy supply structure connectedwith the propeller structures is installed on the main rack body; the four propeller structure positions are distributed in an X-shaped array with unequal included angles; after the rotating speed isregulated and controlled through the electronic speed regulator, the four propeller structures are independently subjected to speed regulation to complete hovering motion, lifting motion, pitching motion, transverse rolling motion and yawing motion, and the control efficiency is low; the four-axis aircraft is simple in mechanical structure and convenient to control, and complex aerodynamic problems do not need to be considered.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a four-rotor aircraft frame. Background technique [0002] The four-rotor aircraft is powered by four motors. The layout of the four motors is generally cross-shaped and X-shaped. The operator can send instructions through the radio equipment to make the four motors rotate at different speeds. The rotation speed of the quadrotor can provide different pulling force, so that the flight direction and flight speed of the quadrotor can be controlled. [0003] It is very simple and practical to use quadrotors to complete some tasks, such as aerial photography, surveillance, tracking, search, reconnaissance, exploration, terrain mapping, disaster relief, transportation, etc. [0004] At present, the mechanical structure of the quadcopter is complex, the control is not convenient enough, the control efficiency is low, and complex aerodynamics need to be considered.
