specific Embodiment approach 1

[0021] Specific implementation mode one: refer to figure 1 and figure 2 Describe this embodiment in detail, a kind of ground and shipboard small unmanned aerial vehicle recovery system described in this embodiment, which includes a foldable sky hook 2, a recovery slideway and a buffer device 3 , arresting rope 11, capture net 5, recovery support 6, arresting rope support arm 7 and guiding device,

[0022] The recovery bracket 6 is used to drive the recovery slideway and the buffer device 3 to move,

[0023] Recovery slideway and buffer device 3 comprise traction rope 4, brake 8, reel 9 with brake pad, two groups of fixed pulleys 10 and housing 12, traction rope 4, brake 8, reel 9 with brake pad and Two sets of fixed pulleys 10 are all arranged in the housing 12,

[0024] The free end of traction rope 4 drags one end of catch net 5 through two groups of fixed pulleys 10 and slides toward the direction of UAV 1, and the reel 9 with brake pad is connected with the other end o...

specific Embodiment approach 2

[0034] Specific embodiment 2: This embodiment is a further description of the ground and ship-borne small unmanned aerial vehicle recovery system described in the specific embodiment 1 of a kind of wire-net composite machine back skyhook collision line type. In this embodiment, the foldable The skyhook 2 is provided with a quick locking device, and the quick locking device is used to complete locking with the arresting rope 11 to avoid decoupling after capture.

specific Embodiment approach 3

[0035] Specific embodiment 3: This embodiment is a method for recovering a wire-mesh compound machine with a skyhook hitting the line on the ground and a ship-borne small unmanned aerial vehicle. The skyhook collision line type ground and shipborne small unmanned aerial vehicle recovery system is realized, and described method comprises the following steps:

[0036] Step 1. When the UAV 1 approaches the arresting rope 11 according to the guiding device at its end, the foldable skyhook 2 pops up according to the control instruction, and is hooked on the arresting rope 11;

[0037] Step 2: The mounted UAV 1 will pull the arresting rope 11 to continue moving. At this time, the free end of the traction rope 4 drags the capture net 5 to the direction of the UAV 1 through two sets of fixed pulleys 10 until the UAV 1 bumps into the capture net 5, and the UAV 1 is hooked on the capture net 5 by the nose barb on it, so as to realize the recovery of the UAV 1.

Abstract

The invention discloses a wire mesh combined machine back antenna hook collision line type ground surface and shipboard recovery system and method for a small-sized unmanned aerial vehicle, and relates to the field of recovery of small-sized fixed-wing unmanned aerial vehicles. The recovery system and the method aims to solve the problem that accurate fixed-point recovery method cannot be realizedand the unmanned aerial vehicle can be damaged easily due to the ground surface and shipboard recovery mode in the existing small-sized fixed-wing unmanned aerial vehicle is solved, and the problem that ground surface and shipboard recovery mode is not suitable for a high-aspect-span unmanned aerial vehicle is also solved. When the unmanned aerial vehicle approaches a blocking rope according to aguiding device at the tail end of the unmanned aerial vehicle, and a folding type antenna is bounced according to a control command, and is hung on the blocking rope; and the hung unmanned aerial vehicle can drag the blocking rope to continuously move, a free end of a traction rope drags a capturing net to slide in the direction of the unmanned aerial vehicle through two fixed pulleys until the unmanned aerial vehicle collides with the capturing net, the unmanned aerial vehicle is hooked on the capturing net through a machine nose barb on the unmanned aerial vehicle, and the unmanned aerial vehicle can be recycled. The recovery system and the method are used for recovering the unmanned aerial vehicle.

Description

technical field [0001] The present invention relates to the recovery of small fixed-wing unmanned aerial vehicles. It belongs to the field of recovery of small fixed-wing unmanned aerial vehicles. Background technique [0002] With the wide application of high-tech in weapons and equipment, the research and development of UAVs has made breakthrough progress, and has frequently appeared in several local wars, and has repeatedly made military exploits, and has been highly praised by military personnel from various countries. Among them, fixed-wing UAVs have been used most in the military field due to their advantages in flight speed and flight distance, but their launch and recovery are more difficult than unmanned helicopters and multi-rotor UAVs. The length of UAV recovery time will directly affect the efficiency of UAV dispatch, and then affect the combat effectiveness. At present, large-scale fixed-wing UAVs mostly adopt the recovery method of autonomous landing, but the...
