Abstract

The invention relates to the field of aircraft design, in particular to an aircraft flap fixing device. The purpose of this device is to fix the cover of the aircraft, to ensure that the cover does not come off, to prevent swaying with the wind, and to damage the surface coating of the airframe structure. The device includes a first fixed base, a rocker arm, a plug and a second fixed base; the first fixed base is fixed on the aircraft hatch; one end of the rocker arm is installed on the first fixed base, and the rocker arm can rotate around the first fixed base The plug is installed on the other end of the rocker arm and can rotate with the rocker arm, and the plug is provided with a tongue; the second fixed base is fixed on the cover frame of the body structure, and the second fixed base is provided with a socket for connecting the tongue Fixing hole. The space occupied by the device can be reduced through the arrangement of the rotatable rocker arm, and the aircraft hatch can be fully opened and firmly fixed.

Description

technical field [0001] The invention relates to the field of aircraft design, in particular to an aircraft flap fixing device. Background technique [0002] Due to the limited number of carrier-based aircraft in the aircraft carrier hangar, many carrier-based aircraft are usually parked on the deck. There are a large number and complex types of aircraft onboard aircraft carriers, and there are various types of maintenance equipment and parts. With the improvement of the maintenance requirements of carrier-based aircraft on the ship surface, it is necessary to carry out non-detachable design of detachable parts such as mouth covers to prevent the loss of parts and Wrong outfit. Traditional flaps usually use hinges or ropes to keep the flap from coming off. Due to the existence of deck wind, the flap usually sways with the wind, causing the flap to collide with the paint layer on the body surface, especially for the coating of stealth aircraft, which will cause serious damag...
