Problems solved by technology

However, due to the special structure of the coaxial dual-rotor UAV, it will not perform complex maneuvers like the multi-rotor UAV during flight. Therefore, the six degrees of freedom of the platform appear to be too much.
[0004] 2. Most existing platforms do not have sensors installed and cannot collect flight data of UAVs
[0005] 3. A small number of platforms equipped with sensors do not have the function of uploading the collected flight data to the host computer for processing and saving

Abstract

The invention discloses a ground flight test platform and test method for a coaxial double-rotor unmanned aerial vehicle and relates to the technical field of unmanned aerial vehicle tests. The groundflight test platform comprises a mechanical part and a control part. a sensor is arranged on the mechanical part, and data are collected through stm32. According to data receiving and data processingparts, the data are received by an HC05 Bluetooth module, and operation is conducted through an upper computer. The ground flight test platform comprehensively applies knowledge of the mechanical, sensing and software fields, specific to the flight characteristics of the coaxial double-rotor unmanned aerial vehicle, the mechanical structure of the platform is simplified, and data collection and data processing functions are added. Flight parameters of the unmanned aerial vehicle can be detected in real time while the unmanned aerial vehicle is protected, and later adjustment is facilitated. The sensor is replaced, thus the ground flight test platform can meet the requirements of different types of unmanned aerial vehicles and detection tasks of different measuring ranges, and good applicability is achieved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle testing, in particular to a ground flight testing platform and testing method for a coaxial double-rotor unmanned aerial vehicle. Background technique [0002] There are many types of existing UAV ground flight test platforms, and their structures are relatively similar, that is, they consist of a frame fixed on the ground and several rotating parts and telescopic parts. A few platforms will add sensors to collect some flight parameters. The above scheme has the following problems: [0003] 1. Existing platforms are mostly designed for multi-rotor drones, generally with six degrees of freedom. However, due to the special structure of the coaxial dual-rotor UAV, it will not perform complex maneuvers like multi-rotor UAVs during flight, so the platform has too many six degrees of freedom. [0004] 2. Most of the existing platforms are not equipped with sensors and cannot collect t...
