Landing aid device of unmanned helicopter

Abstract

The invention belongs to the technical field of unmanned helicopters, particularly relates to a landing aid device of an unmanned helicopter. The device comprises an on-and-off control circuit and a magnetic module connected to the on-and-off control circuit, wherein the magnetic module is arranged on a landing gear of the unmanned helicopter, the on-and-off control circuit is arranged in a cabin of the unmanned helicopter and connected with a flight control system of the unmanned helicopter, the on-and-off control circuit comprises wires, a lithium battery and a relay switch, the lithium battery are connected with the relay switch through the wires to form a closed control loop, and the magnetic module is connected to the closed control loop. According to the device, landing and locking of the unmanned helicopter on a deck of a ship with six degrees of freedom are conducted, and side turning and slipping of the helicopter can be avoided.

Description

technical field [0001] The invention belongs to the technical field of unmanned helicopters, in particular to an unmanned helicopter landing auxiliary device. Background technique [0002] Shipborne unmanned helicopters are an indispensable part of the combat system of modern surface ships, and will also play an important role in future wars. The technical core of the unmanned shipborne helicopter is to design and develop a very effective guidance system, so that the helicopter can land autonomously and safely on the ship moving in six degrees of freedom. It is worth mentioning that when the unmanned helicopter lands on the deck After boarding, the helicopter needs to be fixed and locked, but installing a hook and lock device on the deck is not a simple matter. It not only increases the experimental steps, but also puts forward higher requirements for the precise landing of the helicopter. [0003] However, it is not complicated to design a harpoon device for some small unm...

AI Technical Summary

Problems solved by technology

[0003] However, it is not complicated to design a harpoon device for some small unmanned helicopters, but for large unmanned helicopters, the use of a harpoon device not only increases the weight of the body, but also designs a harpoon device that can hook and lock a drone weighing several hundred kilograms. The harpoon is not simple, and corresponding mechanical structures or devices must be designed on the deck of the ship and the landing gear of the fuselage.
