Problems solved by technology

The length of battery life seriously affects the efficiency of mission execution. With the development of various miniaturized and modular UAV systems, traditional tethered UAVs consume a lot of power, and traditional tethered UAVs land first. , the cables are scattered on the ground, and then the cables are recycled. There is a problem of inconvenient cable recycling. It is very necessary to design a general energy-saving, high-efficiency, long-lasting, and easy-to-control tethered UAV system

Abstract

The invention discloses a mooring unmanned aerial vehicle, and belongs to the technical field of unmanned aerial vehicles. The mooring unmanned aerial vehicle comprises a balloon mounted in a ball cage, and the balloon is a hydrogen balloon or a helium balloon; four machine arms distributed evenly at intervals are arranged around the outer ring of the ball cage, one end of each machine arm is an inner end connected to the ball cage, and the other end of each machine arm is an outer end pointing to the outside the ball cage; a rotor assembly is arranged at the outer end, pointing to the outside the ball cage, of each machine arm, each rotor assembly comprises a propeller motor and a propeller driven by the propeller motor, and a propeller center axis extends horizontally; and balloon vertical center axes surrounded by four propellers on the four machine arms are arranged along a circumferential line sequentially, and the center axis of each propeller is tangent to the circumferential line. According to the mooring unmanned aerial vehicle, cables are easy to recycle, and the mooring unmanned aerial vehicle is capable of realizing the hover in unlimited time and space.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a tethered unmanned aerial vehicle. Background technique [0002] Early unmanned aerial vehicles were more used as target aircraft and reconnaissance aircraft for experimental training, reconnaissance and surveillance. Development and application, unmanned aerial vehicles (UAVs) have gradually developed into a new type of air power, which can play an important role in boring mission fields, harsh environment mission fields and dangerous mission fields. In recent years, countries all over the world are vigorously developing multi-rotor UAVs, which have been widely used in both military and civilian applications. Multi-rotor drones are small in size, low in cost, can hover at fixed points, and can take off and land vertically. Therefore, they can be used for military tasks such as transporting materials, battlefield surveillance, and border inspections...
