Abstract

The invention relates to a duct type multi-rotor tethered drone and a control system thereof, belongs to the field of drones, and aims to solve the problems that existing drones are short in flight duration and prone to crash due to the fact that the rotors of the drones are exposed. The duct type multi-rotor tethered drone is characterized in that the an inner central pipe is connected with an outer duct pipe through a group of guide vanes, a group of carbon fiber pipes is fixedly mounted on the outer wall of the lateral side of a block formed by central plates, the middle section of each carbon fiber pipe is fixed with the wall of the duct pipe, and an auxiliary rotor is mounted at the tail end of each carbon fiber pipe through an auxiliary motor; a hardware control system is mounted onthe upper surface of the central plate block, a main motor is coaxially mounted on the lower surface of the central plate block, the main motor drives a main rotor, and a power supply system is arranged beside the main motor; the hardware control system is connected with the main motor, a group of auxiliary motors, the power supply system, a video collecting unit and an automatic pilot, and a tether is connected with the hardware control system, the main motor, the group of auxiliary motors and the video collecting unit through the power supply system. The duct type multi-rotor tethered dronecan constantly work around the clock.

Description

technical field [0001] The invention relates to a ducted multi-rotor moored unmanned aerial vehicle and a control system thereof. Background technique [0002] Unmanned Aerial Vehicle (UAV) refers to an aircraft that does not carry an operator and can fly autonomously or be piloted by remote control. Multi-rotor UAV is a special unmanned aerial vehicle with three or more rotors. Commonly seen are four-rotor, six-rotor, eight-rotor and other models. By controlling the speed of the motor on each axis , to drive the rotor to generate lift thrust. [0003] In recent years, multi-rotor drones have been widely used in military investigation, security monitoring, communication support, media entertainment, environmental monitoring and other fields. The multi-rotor UAV is stable and easy to operate, and the price is relatively low. It provides great convenience for people and is generally welcomed by users. However, the power supply capability of the traditional multi-rotor UAV h...
