Landing device for vertical lifting aircraft and ship

Abstract

The invention provides a landing device for a vertical lifting aircraft and a ship. The landing device comprises a lift-off platform, wherein a plurality of power devices used for driving the lift-offplatform to ascend or descend are arranged on the lift-off platform, and a locking device for locking the aircraft is arranged on the lift-off platform; the locking device used for locking the aircraft is arranged on the lift-off platform; a power cable and a main probe pipe are arranged below the lift-off platform, and a main pull-off cable is arranged in the main probe pipe; and a damping landing frame is further arranged below the lift-off platform. The ship is provided with the landing device. According to the landing device, large impact on a deck when the aircraft lands on the deck canbe avoided, and the landing safety of the aircraft is improved.

Description

technical field [0001] The invention relates to the field of landing aids for ship-borne vertical lift aircraft, in particular to a landing device for vertical lift aircraft and a ship with the landing device. Background technique [0002] Ship-borne vertical lift aircraft, such as helicopters and unmanned aerial vehicles, need to rely on the landing device when landing on the ship. However, the existing landing device mainly makes the aircraft perform a rigid landing on the ship. Taking helicopters as an example, the landing devices of helicopters mainly include three types of landing devices: "pull-down" type, "harpoon-grid" type, and "landing aid net" type. [0003] The drag-and-drop landing device is mainly composed of the index, index winch, main probe, tail probe, and the drag and drop winch, clamping mechanism and control room on the ship. When the helicopter is ready to land, the helicopter hovers at a height of 6 to 8 meters above the flight deck, releases the main...

AI Technical Summary

Problems solved by technology

[0006] At present, the landing gear of helicopters mainly includes three types: skid type, wheel type, skid and wheel combination type, wherein the skid type, skid and wheel combination type landing gear has no shock absorption effect, although the wheel type landing gear has certain damping effect. Shock effect, but because of the heavy weight, the shock absorption effect is not ideal

Regardless of the helicopter with skid type or wheeled landing gear, there are certain difficulties in landing helicopters at present

The main problem of the three existing landing methods is that they are not very versatile. The pull-down method can better solve the problem of helicopter landing in sea conditions below level 6, but it is only suitable for large helicopters with high lift, not suitable for small and medium-sized helicopters with insufficient lift. Helicopter; harpoon-grid type (only suitable for small helicopters of 4 ton to 5 tons) and landing net type helicopter landing deck are all rigid landing decks, which are only suitable for sea conditions below level 5, because the ship is swaying on the sea surface Shaking and undulating, the helicopter is easy to hit the deck directly when it lands vertically

In addition, if the falling speed of the helicopter is not well controlled during the landing process, the moment the helicopter stops on the deck, it will also collide with the deck with a large impact, resulting in an accident. one of the higher

At present, the vertical lift unmanned aircraft can only use the tethered type to land on the unmanned ship. Due to the limitation of the length of the tethered rope, the vertical lift unmanned aircraft cannot be far away from the unmanned ship when it is used, which limits the role of the unmanned aircraft.
