Embodiment

[0040] There are three flight states of UAVs: takeoff and landing, hovering and flight, among which the test in flight state is the most difficult.

[0041] In order to simulate the extreme flight state, we need to let the UAV run at a higher flight speed, which is very high, generally can reach 60kph (kilometers per hour), if it relies on the UAV's own power system to accelerate to the required speed , the required space is very large, and may require tens of meters or even hundreds of meters, which greatly increases the cost of the test equipment; therefore, this embodiment proposes a UAV with good test performance and low cost For performance test equipment, see attached figure 1 , which includes a housing, the housing is provided with a flight channel for the flight of the drone; the opposite sides of the housing are provided with an air inlet 40 and an air outlet 70, and the air inlet 40 and the air outlet 70 form an air inlet passage ; The air intake passage and the fli...

Abstract

The invention discloses a device and a method for testing wind resistance of an unmanned aerial vehicle. The device comprises a shell; a flight channel for flight of the unmanned aerial vehicle is arranged in the shell; an air inlet and an air outlet are formed in the two opposite sides of the shell; an air inlet channel is formed by the air inlet and the air outlet; and the air inlet channel andthe flight channel are intersected. According to the device, a driven apparatus is driven by the gravity actions of counterweight parts in a driving apparatus, so that the unmanned aerial vehicle canbe driven to do an accelerated motion, and the counterweight parts with different gravities can accelerate the unmanned aerial vehicle to different speeds; the spatial position of the unmanned aerialvehicle can be adjusted through a length adjusting mechanism on the driven apparatus, so that the unmanned aerial vehicle can be accelerated, the spatial position of the unmanned aerial vehicle can beadjusted, and the size and the direction of the accelerated unmanned aerial vehicle are controllable; and the cost is low.

Description

technical field [0001] The invention relates to a UAV testing device, in particular to a UAV wind resistance testing device and a method thereof. Background technique [0002] UAVs will encounter various airflows during flight. These airflows will interfere with the flight status of UAVs, and users hope that UAVs will fly in a predetermined way. For this reason, UAVs need to have wind resistance. That is to say, the UAV can return to the expected flight state under the disturbance of airflow. In order to test the wind resistance of the drone, we need a device to test its wind resistance. [0003] The easiest way is to put the UAV directly in the natural environment for flight test, but this test method is subject to various restrictions in the natural environment, and its test conditions do not necessarily meet human needs. For example, we hope that the crosswind can reach 8m / s wind speed, but it may not be achieved in natural environment. [0004] In the prior art, wind ...
