Problems solved by technology

[0003] At present, the rotor UAV can achieve the effect of emergency deceleration to achieve braking, while the fixed-wing UAV does not have a more mature function of emergency deceleration to achieve braking. Therefore, it is necessary to provide a fixed-wing UAV that can be used Man-machine emergency deceleration system to improve the maneuverability and flexibility of fixed-wing drones

Abstract

The invention discloses an emergency speed reduction system of an unmanned aerial vehicle, a working method of the emergency speed reduction system and the unmanned aerial vehicle. The emergency speed reduction system comprises a wind resistance generating device, the wind resistance generating device comprises a connecting base and a steering engine, and the connecting base is provided with a first storage groove, a second storage groove and a shaft hole; a guide hole is formed between the first storage groove and the second storage groove, an upper wind resistance plate and a lower wind resistance plate are arranged in the first storage groove, a transmission plate is arranged between the upper wind resistance plate and the lower wind resistance plate, a connecting shaft is inserted into the shaft hole, reinforcing plates are arranged on the back face of the upper wind resistance plate and the back face of the lower wind resistance plate, and the reinforcing plates penetrate through the guide hole; and an L-shaped connecting piece is arranged in the second storage groove, a mounting groove is formed in the reinforcing plate, and a first reset spring is arranged between the back face of the L-shaped connecting piece and the groove bottom of the mounting groove. The emergency speed reduction system of the unmanned aerial vehicle has the advantages that the overall wind resistance of the unmanned aerial vehicle can be continuously increased by the emergency speed reduction system of the unmanned aerial vehicle through control, accordingly, speed reduction can be realized, and the effect similar to braking can be achieved.

Description

technical field [0001] The invention relates to an emergency deceleration system of an unmanned aerial vehicle, its working method and an unmanned aerial vehicle. Background technique [0002] UAVs have the great advantages of being able to adapt to complex and harsh environments, not requiring personnel to drive, and not causing personnel losses, so they have been used more and more widely. At present, UAV technology is used in remote sensing measurement and control, aerial photography surveying and mapping, environmental reconnaissance and other fields. With the increase of applications, UAV technology is getting hotter and hotter, and the types of UAVs tend to be diversified. Among them, fixed-wing UAVs occupy a large proportion in the field of UAVs. Fixed-wing UAVs have the advantages of long flight distance, large range, stable flight, and safety. [0003] At present, the rotor UAV can achieve the effect of emergency deceleration to achieve braking, while the fixed-wi...
