External field aircraft canopy organic glass broken hole damage repairing method

Abstract

The invention relates to the technical field of aviation organic glass repairing, in particular to an external field aircraft canopy organic glass broken hole damage repairing method which comprises the steps that a hole damage area is determined through visual inspection and a crazing detector, a marking pen is used for marking the damage repairing area, and the positions of all reference lines are drawn on seat canopy glass; a step-by-step grinding method is adopted, the damaged hole is ground into a specified circular hole, and then the hole is ground into a specified tapered wedge cone size; manufacturing an inlaying patch to ensure that the inlaying patch is attached to the inlaying hole; a reinforcing patch is manufactured, and it is guaranteed that the reinforcing patch is attached to a damaged cementing area in canopy organic glass; mounting an inlaid patch; mounting a reinforcing patch; carrying out post-treatment; and closing the canopy, and filling nitrogen according to the specified requirements to verify the sealing performance and strength of the repair patch. According to the invention, external field rapid and effective repair is realized, the aircraft maintenance cost is reduced, and the repair quality is ensured. And the process method is simple and easy to operate, the repair period is shortened, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of aviation plexiglass repair, in particular to a method for repairing damage to plexiglass holes in an outfield aircraft canopy cover. Background technique [0002] Based on the advantages of excellent light transmittance, low density and good strength, and the rapid development of modern aviation manufacturing technology, plexiglass has been widely used in aircraft cockpit covers to meet the needs of pilots to observe the outside world. At the same time, as a structural part of the aircraft body, its structure is complete It is closely related to the living environment of the pilot and directly affects the flight safety and mission completion. It is a key component of the aircraft. It is composed of the metal frame of the cockpit cover and the aviation plexiglass of the cockpit cover. It integrates various functions and requires high structural strength. , Light weight and good optical performance, wide fi...

AI Technical Summary

Problems solved by technology

The plexiglass of the canopy is at the front of the aircraft, and it is vulnerable to perforation and damage by foreign objects (birds, sand, etc.) during takeoff and landing. For such damage, the current method is to replace the entire canopy or send the entire canopy back to the repair base for replacement The whole piece of damaged glass is repaired by returning it to the aircraft for installation. This type of method has problems such as long order cycle for canopy (canopy glass) parts, high replacement cost, long repair time, and low aircraft operation rate, which are difficult to meet the needs of the users. The need for rapid repair in the field requires research and adoption of new repair methods to solve this problem
