Abstract

The invention provides a miniature tandem reversal dual-rotor aircraft. The aircraft comprises a main board, a control system, a battery, a first aircraft driving mechanism, a second aircraft driving mechanism and a support, wherein the first aircraft driving mechanism, the second aircraft driving mechanism, the control system and the battery are all mounted on the mainboard; the support is installed at the bottom end of the main board. The first aircraft driving mechanism is used for providing lift force for the aircraft and providing torsional moment for the aircraft; the second aircraft driving mechanism is used for providing lift force for the aircraft and controlling the yaw angle of the aircraft. According to the novel aircraft control mode, only two highly-integrated aircraft driving mechanisms are used as drivers of the aircraft, attitude control is conducted in cooperation with a passive hinge structure and a fixed connecting piece, two drivers are omitted compared with the structure in the current mainstream technology, and therefore the weight of the aircraft is reduced. Therefore, a complicated mechanical structure of the swash plate is avoided, and the production cost of the micro aircraft is reduced.

Description

technical field [0001] The present invention relates to the field of unmanned aerial vehicles, in particular to a miniature tandem inverted dual-rotor aircraft, especially to a kind of using only two DC brushless motors as drivers, and adjusting the angle of attack of propeller blades with passive hinges, A miniature tandem contra-rotating helicopter whose attitude is controlled. Background technique [0002] Small unmanned aerial vehicles are becoming increasingly popular, especially rotorcraft that can hover in three dimensions. This rotor-type UAV has a wide range of applications, including environmental monitoring, plant protection, mine detection, and item transportation. For the tandem contra-rotor helicopter, its two rotors are arranged in tandem front and back, and the rear propeller is higher than the front propeller, which further improves the compactness of the aircraft. Both propellers of this type of helicopter provide lift, and the front rotor is usually used...
