Problems solved by technology

[0002] Helicopters are often stationed at coastal airports during course training. Due to the poor conditions of coastal airports, helicopters can only be parked in the open air. The main rotor of a more flexible helicopter is only pulled by a cloth belt. On the fixed point of the aircraft fuselage, when a strong typhoon strikes, the following problems will occur: first, the main rotor of the helicopter will swing downwards, and then rebound upwards in an instant. The main rotor is broken; second, the helicopter is prone to rollover

Abstract

The invention discloses an anti-typhoon fixing device for a helicopter. The device is characterized by comprising a device for fixing rotation of the helicopter and a chain mechanism for stabilizing the body of the helicopter, wherein the fixing device is arranged between the end part of a main rotor of the helicopter and a landing gear; one end of the chain mechanism is arranged on the body of the helicopter, and the other end of the chain mechanism is fixed on the ground; and the root part of the main rotor of the helicopter is also provided with a spacing device for preventing each blade of the main rotor of the helicopter from independent rotation. The device has the effect of preventing the main rotor of the helicopter from swinging up and down, and also has the effect of stably landing the helicopter on the ground; and the possibility of rolling over the body of the helicopter is effectively prevented.

Description

【Technical field】 [0001] The invention relates to a windproof device, in particular to a typhoon-resistant fixing device for a helicopter. 【Background technique】 [0002] Helicopters are often stationed at coastal airports during course training. Due to the poor conditions of coastal airports, helicopters can only be parked in the open air. The main rotor of a more flexible helicopter is only pulled by a cloth belt. On the fixed point of the aircraft fuselage, when a strong typhoon strikes, the following problems will occur: first, the main rotor of the helicopter will swing downwards, and then rebound upwards in an instant. Second, the helicopter is prone to rollover. [0003] In order to avoid the above-mentioned accidents and ensure the normal training of the troops, there is an urgent need for a fixing device that can limit the main rotor of the helicopter from swinging up and down, preventing the main rotor of the helicopter from breaking; There are reliable fixes to ...
