A free take-off and landing tilting power miniature fixed-wing unmanned aerial vehicle

Abstract

The invention discloses a tilting power miniature fixed-wing unmanned aerial vehicle with free take-off and landing, which belongs to the technical field of miniature unmanned aerial vehicles; specifically, there are two main wings on the left and right sides of the main body, and a micro brushless motor and Micro propeller; the bottom end is an aerodynamic rudder surface; at the same time, a servo mechanism and a tilting mechanism are installed on the top of each main wing; the micro brushless motor is installed under the micro propeller and fixed on the tilting mechanism, and the tilting mechanism passes through The connecting rod connects the output rocker arm of the servo mechanism; the servo mechanism is installed on the leading edge of the main wing. When the UAV is parked on the ground, the servo mechanism controls the tilting mechanism to rotate, thereby controlling the direction of the propeller pulling force. The angle between the propeller axis and the UAV body axis reaches plus or minus 60 degrees, so the UAV passes through the front After landing on the ground or on the opposite side, it can take off from the original place, which makes the drone have a higher survivability in performing tasks.

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
