A collapsible unmanned aerial vehicle that can be carried by a soldier, can be stored and launched in a cylinder

Abstract

The invention discloses a collapsible unmanned aerial vehicle which is carried by an individual soldier and can be stored and launched in a cylinder, which comprises a fuselage, a main wing, a grille tail mechanism, a vertical tail and a power assembly. The tail of the fuselage is provided. The main wings at the upper and lower ends of the fuselage are connected by the main wing folding axis. The main wing folding axis is set at 30%~40% of the span length of the main wing. The fuselage is connected; the powertrain includes the sprocket propeller hub, the drive motor and the motor gear, the motor gear and the sprocket propeller hub are internally meshed, and the motor gear is connected to the output end of the drive motor, and the sprocket propeller hub is provided with There are at least two fixing seats, each of which is connected with a propeller through a propeller folding shaft. The beneficial effects of the present invention are as follows: stable flight, high reliability, reduced wing load, improved battery life, small opening resistance, easy to carry by individual soldiers, and the whole layout is a self-stabilizing layout.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to a collapsible unmanned aerial vehicle which is carried by an individual soldier and can be stored and launched in a cylinder. Background technique [0002] The "Switchblade" micro-UAV was developed by American Aviation Environmental Corporation in California, USA. It can be launched by a single soldier using a low-cost catapult, and then fly on battery power. It carries surveillance equipment that can track and monitor moving targets on the ground, and is also equipped with a small bomb inside the body. The reason why this small attack drone can be carried in the launch tube is because it uses two pairs of front and rear wings that can be folded, unfolded and locked like a switchblade. [0003] The "Switchblade" drone is only about 45 centimeters long and can fit into an infantry backpack. The U.S. military believes that the use of "switchblades" can significantly weaken enemy fire...

Problems solved by technology

Second, due to the similar area of ​​the front and rear wings, the resulting control moments balance each other, so the self-stability of the pitch is poor, and the oscillation of the pitch attitude control is prone to occur.
