Embodiment Construction

[0079] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below through the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0080] The embodiment of the present application discloses a forced landing method for a fixed-wing UAV.

[0081] refer to figure 1 , the method includes:

[0082] 101. When the fixed-wing UAV enters the forced landing procedure, obtain the current airspeed of the fixed-wing UAV.

[0083] Among them, during the flight of the fixed-wing UAV, there may be unexpected situations such as aircraft mechanical and electrical equipment failure, aircraft lost, fuel exhaustion or sudden deterioration of weather conditions. At this time, it cannot land in normal procedures and needs to enter the force...

Abstract

The present application discloses a method and system for forced landing of a fixed-wing UAV. The method includes: obtaining the current airspeed of the fixed-wing UAV when the fixed-wing UAV enters the forced landing procedure; Adjust the current airspeed to the gliding flight airspeed; obtain the ground terrain information corresponding to the current airspace of the fixed-wing UAV; select the forced landing area to perform the forced landing and glide mission according to the ground terrain information; during the execution of the forced landing and glide mission, collect the area information of the forced landing area , regional ground wetness and softness information, and regional terrain trend information; according to the regional area information, regional ground wetness and softness information, and regional topographic trend information, a landing grounding plan for the fixed-wing UAV is generated; Landing and grounding scheme, control the fixed-wing UAV to land and ground. The application improves the safety of the fixed-wing unmanned aerial vehicle when it is forced to land in the forced landing area, and reduces the damage rate of the fixed-wing unmanned aerial vehicle when it is forced to land.

Description

technical field [0001] The present application relates to the field of unmanned aerial vehicles, and in particular, to a forced landing method and system of a fixed-wing unmanned aerial vehicle. Background technique [0002] During the mission flight, the fixed-wing UAV may encounter unexpected situations such as aircraft mechanical and electrical equipment failure, aircraft lost, fuel exhaustion, or sudden deterioration of weather conditions. At this time, normal procedures cannot be used to land. cause a crash. [0003] The existing emergency landing method is as follows: if the flight cannot be normally flown, it is necessary to make an emergency emergency landing to a safe area. However, during the mission flight, the external topography is relatively complex, and the flight path may pass through rivers, mountains, fields and other scenes. It is difficult to select the forced landing point. If the forced landing point and method are unreasonable, it is easy to cause the...
