Platform for analyzing stability of multi-rotor aircraft

Abstract

The invention relates to a platform for analyzing the stability of a multi-rotor aircraft. The analysis platform comprises a base, a ball head joint bearing, a lower slide bar, an upper slide bar, a universal joint, an aircraft tray, and a force measuring mechanism. The upper end face of the base is connected to the lower slide bar through the ball head joint bearing. One side of the lower slide bar is provided with the upper slide bar, which can slide up and down relative to the lower slide bar. The top end of the upper slide bar is connected to the aircraft tray through the universal joint.The force measuring mechanism measures the force through the position change when the upper slide bar and lower slide bar slide relative to each other. The structure of the analysis platform is simple. After an aircraft is loaded, the actual flying state of a multi-rotor aircraft can be simulated in a lab, the actual posture change information can be obtained not just through purely theoretical dynamic modeling; during the test process, multiple attitude sensors on the multi-rotor aircraft can measure the attitude information in real time during the flying process of the aircraft, the attitudeinformation is sent to a PC, and the test result is closer to the real flight environment.

Description

technical field [0001] The invention relates to the technical field of stability testing of rotorcraft, in particular to a stability analysis platform for multi-rotor aircraft, which is used for real-time testing of the stability of flight poses. Background technique [0002] Unmanned Aerial Vehicle (UAV) refers to a flight power device that can realize autonomous or long-distance remote control flight and does not require operators. There are more extensive applications in the military field, such as tedious and dangerous tasks such as surveillance, rescue, geological exploration, power line inspection and logistics express. [0003] As an important branch of unmanned aerial vehicles, multi-rotor aircraft has the advantages of flexible maneuverability, simple structure, convenient manipulation, vertical take-off and landing, low cost, and relatively complex tasks that can be performed compared with fixed-wing aircraft and flapping-wing aircraft. The advantages of diversifi...
