A portable miniature coaxial scull unmanned aerial vehicle and its control method

Abstract

The invention discloses a portable miniature coaxial double propeller unmanned aerial vehicle and its control method. The unmanned aerial vehicle includes a casing, a coaxial double propeller, a transmission rod, a motor, a battery, an autopilot system, and four air control surfaces and steering gear etc. The coaxial twin propellers are installed on the upper end of the transmission rod, and the four rudder surfaces are distributed on the outer wall of the bottom of the casing in a cross shape. The autopilot system automatically realizes the attitude control of the UAV. By adjusting the speed difference of the dual propellers and the deflection angle of the air rudder surface, the UAV can generate a torque difference, and produce a pitch angle / roll angle deflection under the action of the rudder surface. Thereby realizing forward and backward movement. In addition, circular protective covers can be designed and installed on the periphery of the four rudder surfaces, which can not only protect the rudder surfaces, but also maximize the efficiency of the use of propeller washing. The drone of the invention has the advantages of being light and compact, easy to carry, easy to operate, simple in control design, good in stability, strong in wind resistance, low in requirements for application scenarios and take-off and landing conditions, and flexible in maneuvering.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a portable miniature coaxial scull unmanned aerial vehicle and a control method thereof. Background technique [0002] With the development of information technology, in modern warfare, unmanned aerial vehicles that are easy to operate, easy to carry, and powerful have attracted the attention of various countries; for the special needs of individual combat, a portable and powerful aircraft has been developed. Since the current single-rotor cylindrical UAV has the problem of self-spin of the body, in order to overcome the problem of spin torque, the single-rotor UAV must use a large area of ​​air rudder surface to overcome its own torque, resulting in the UAV itself The volume is too large and the maneuverability is poor, which cannot meet the needs of high mobility operations. Contents of the invention [0003] Purpose of the invention: The purpose of the pres...
