Wind room with detecting function for simulating outdoor flight environment of unmanned aerial vehicle

Abstract

The invention discloses a wind room with a detecting function for simulating an outdoor flight environment of an unmanned aerial vehicle. The wind room comprises a room body and a working unit, wherein the working unit is composed of a blower fan fixing device, a slide rail and a blower fan. The roof of the room body is a semi-cylindrical closed structural space. The vertical distance between ground of the room body and the circle center of the semi-cylindrical roof is not less than the maximal flight height of the unmanned aerial vehicle in normal operation. The width of the room body is not less than four times of an effective spraying amplitude of the unmanned aerial vehicle in normal operation. The length of the room body is not less than an average operation visual measurement distance of a pilot. The wind room satisfies a requirement for free flight of the unmanned aerial vehicle and can simulate a wind environment of the unmanned aerial in outdoor operation. Factors which comprise wind angle, wind speed and the like and affect operation of the unmanned aerial vehicle are measured. Compared with a traditional wind tunnel test, the wind room has advantages of realizing conversion from a fixed unmanned aerial vehicle mode to a free flight mode, and obtaining a significant scientific meaning in development of an agricultural plant protecting unmanned aerial vehicle in fields of crop pesticide spraying, plant pollination, broadcast spawning, farmland information remote sensing, etc.

Description

Technical field [0001] The invention relates to a technology for detecting the operational performance of an unmanned aerial vehicle, in particular to a wind house with a detection function that simulates the outdoor flight environment of an unmanned aerial vehicle. Background technique [0002] In recent years, agricultural plant protection drones have developed rapidly in the fields of crop spraying pesticides, plant pollination, sowing, and remote sensing of farmland information. Domestic plant protection drones have shown a trend of development. There are many types of drones: oil-powered single rotors. , Electric single-rotor, electric multi-rotor and oil-powered multi-rotor. Pesticide spraying in farmland has gradually transitioned from manual to drone operations. Although drone operations have been vigorously promoted, aircraft operations are unstable in actual operations, and there are a lot of problems such as heavy spraying, leaking sprays, drug drift, and even crashes....

AI Technical Summary

Problems solved by technology

Although field tests can be carried out under the most realistic conditions, due to the instability and uncontrollability of meteorological factors, the results of field tests are difficult to repeat, making it difficult to determine the impact of a certain factor on test results and quantify the effect of this factor become very difficult

Many domestic scholars use indoor wind tunnel tests to study the amount of mist drift and the spraying effect of different types of nozzles, and have made some progress. However, the cost of wind tunnel tests is high. Therefore, an outdoor simulation drone with detection function is designed. Air chambers for flight environments have significant scientific significance
