Problems solved by technology

[0003] The existing landing gear handle sign board is installed on the cockpit instrument panel. Since the sign plate is made of aluminum lettering and does not have the ability to illuminate at night, it is difficult for the driver to identify the position of the landing gear handle when the helicopter retracts and retracts the landing gear at night. In addition, due to the influence of the installation position of the landing gear handle, the subtitles of the signboard are partially blocked, which affects the normal operability of landing gear retraction.
In addition, the installation method of the signboard is riveted, which will cause inconvenience to the subsequent maintenance of the helicopter

Abstract

The invention relates to a sign board for a landing gear handle and an installation method thereof. The invention belongs to the field of aviation cockpit indicating equipment, and specifically relates to a signboard of an aviation landing gear handle. The sign plate of the landing gear handle of the present invention adopts the design concept of light guide plate + LED light emission, and according to the structural characteristics of the landing gear handle, a brand new design of the lettering layout of the sign plate. The installation form is innovatively designed, using four-point screw connection installation, and the installation hole has aesthetic requirements and the ability to tighten to reduce stress. In actual use, it has good night recognition and avoids the problem of partial occlusion of lettering and subtitles.

Description

technical field [0001] The invention belongs to the field of aviation cockpit indicating equipment, and in particular relates to an aircraft landing gear handle label. Background technique [0002] The landing gear handle label and its installation method in the similar existing helicopter landing gear retractable control system are as follows: figure 1 As shown, the landing gear handle signboard (hereinafter referred to as the signboard) is installed near the landing gear handle (1) in the cockpit. The signboard (2) is made of aluminum (material code 2A12T4) with a thickness of 0.5mm. Its lettering (from Drop frame, retractable, put down) is made by corrosion method, the signboard (2) is white on a black background, the font is in accordance with GB4457.3-84, and the surface is painted with white alkyd enamel, the signboard (2) is installed by rivets (3) Riveted for fastening. When the driver needs to perform retraction and retraction of the landing gear, he should pull t...
