“…The propellers are directly driven by the motors without any transmission devices, avoiding energy loss. The cross-shaped structure of the frame is divided into a cross-type and an X-type [6] , and there is also a less common Dtype [7] (asymmetric cross structure, often used in the field of FPV drones to provide a larger field of view for the front camera and avoid obstruction of the propellers, which is not relevant to this article), for attitude measurement and control, the two common structures are basically the same. The X-type structure is more convenient for mounting front cameras and sensors, achieving a more complete flight effect.…”

For the requirements of Unmanned Aerial Vehicles (UAVs) in high payload and small space, the aircraft needs to have the characteristics of high payload, small size and stable control system. This paper designs a coaxial twin-propeller multi-rotor UAV based on the combined control of redundant flight controller and NVIDIA microcomputer. Compared with traditional quadcopter UAVs, each axis is equipped with dual motors and dual propellers in this structure, which not only has high load-bearing capacity but also greatly reduces the occupied space of the aircraft. Through actual tests, it is found that the failure rate is almost 0 with the support of redundant flight controller, and the combined control system can hover stably and locate accurately under harsh conditions. Compared with the traditional flight control system, the system has better maneuverability and lower error offset when the UAV is under high payloads, making it more suitable for the aircraft with coaxial double-propeller multi-rotor structure.
