A device for crack monitoring and repairing of wing components and a method for crack monitoring and repair of wing components

Abstract

The invention relates to a device for crack monitoring and repairing of wing components and a method for crack monitoring and repair of wing components, belonging to the technical field of aircraft component performance safety monitoring equipment. The invention aims to form a crack monitoring and repairing device for wing components by electrode sheets, single-chip microcomputers, batteries, filters, thermal imaging detectors, and galvanometers; The metal fatigue accumulated by vibration will cause different degrees of cracks, and the crack monitoring is realized by using the surface current generated by the electrode sheet and the ammeter monitoring current, and the electrode sheet passes a strong current to the cracked area to make the metal at the crack close to the melting point to automatically repair the crack; The filter eliminates interference waves to ensure the normal crack monitoring; the thermal imaging detector monitors the temperature of small metal pieces when cracks are repaired; the single-chip microcomputer integrates monitoring information and control devices to complete crack repair; the battery provides weak and strong currents required for crack monitoring and repair. The device can detect and eliminate safety hazards formed by metal cracks in wing components.

Description

technical field [0001] The invention relates to a device for crack monitoring and repairing of wing components and a method for crack monitoring and repairing of wing components, belonging to the technical field of aircraft component performance safety monitoring equipment. Background technique [0002] In recent years, my country's aircraft industry has achieved rapid development, and series of aircraft such as C919 have come out one after another. An aircraft is a combination of a whole set of systems, any system or structure failure may cause an accident. The most common cause of failure is metal fatigue. The aircraft will vibrate at various frequencies during flight, plus the pressurization / decompression cycle of each takeoff and landing. If any part is not checked and fatigue fracture occurs, it will cause an accident. In the Amsterdam Air Disaster in 1992, the pins of the engine rack were fatigued and fractured. Two engines fell at the same time and fell into a resid...

AI Technical Summary

Problems solved by technology

As the most important structure for generating lift, the wing is affected by forces in different directions during flight, coupled with the vibration of various frequencies of the aircraft itself during flight, the main components such as the main frame and skin are prone to metal fatigue. As a result, cracks are generated, which poses a great hidden danger to the safety of the aircraft.
