Tilting power miniature fixed-wing unmanned aerial vehicle capable of taking off and landing freely

Abstract

The invention discloses a tilting power miniature fixed-wing unmanned aerial vehicle capable of taking off and landing freely, and belongs to the technical field of miniature unmanned aerial vehicles.Main wings are arranged on a left side and a right side of a main fuselage respectively, and a micro brushless motor and a micro propeller are installed at top ends of the main wings; a bottom end isa pneumatic control surface; meanwhile, a servo mechanism and a tilting mechanism are mounted at the top end of each main wing; the micro brushless motor is arranged below the micro propeller and issimultaneously fixed on the tilting mechanism; the tilting mechanism is connected with an output rocker arm of the servo mechanism through a connecting rod; and the servo mechanism is installed on thefront edge of the main wing. When the unmanned aerial vehicle is parked on the ground, the servo mechanism makes the tilting mechanism rotate so as to control a tension direction of the propeller, and an included angle between an axis of the propeller and the axis of the unmanned aerial vehicle body reaches + / -60 degrees so that the unmanned aerial vehicle can take off from an original place after landing on a front side or a back side, and the unmanned aerial vehicle has a higher survivability in task execution.

Description

technical field [0001] The invention belongs to the technical field of micro unmanned aerial vehicles, in particular to a tilting power miniature fixed-wing unmanned aerial vehicle with free take-off and landing. Background technique [0002] Recently, with the continuous expansion of UAV market demand and the continuous development of UAV technology, the miniaturization of UAV has become one of the important development directions in this field. [0003] As a category of unmanned aerial vehicles, Micro Air Vehicle (MAV) was first proposed by the US Defense Advanced Research Projects Agency (DARPA) at the Future Military Conference in 1992. At that time, DARPA defined MAV as: the flight speed of MAV is about 5-20m / s, and the maximum design length of its fuselage is between 10-15cm, which is about the size of an adult's palm. [0004] With the development of science and technology and in-depth research on actual use, the U.S. military has gradually relaxed the size restricti...

Problems solved by technology

[0006] In order to ensure the ability of the UAV to fly in a small space, it is very necessary to have good maneuverability, that is, the ability to hover. Nowadays, the UAVs that achieve hovering in the field of fixed-wing micro-aircraft mostly adopt a tail seat configuration. The tail seat configuration has the characteristics of light weight and low resistance, which is very suitable for small aircraft; however, the wind resistance performance has always been its Achilles heel

At the same time, this type of tiny aircraft often has a strong ability to resist falling, but once this type of aircraft lands on the ground, even if there is no damage, it is still difficult for the aircraft to take off again and continue to perform missions
