Application verification method of multi-series thermal shrinkage sealing protection materials for helicopter

Abstract

The invention belongs to the technical field of helicopter sealing protection materials, and particularly relates to an application verification method of a multi-series thermal shrinkage sealing protection material for a helicopter. The method is characterized by comprising the following steps: S1, designing a typical test piece; s2, manufacturing a typical test piece; s3, carrying out initial performance detection; s4, determining an acceleration test environment spectrum and a test program; s5, implementing an environment test; and S6, carrying out performance detection and verification. The complete application verification method for the multi-series heat-shrinkable sealing protection materials for the helicopters is created, the blank in the prior art is filled, and application verification of the multi-series heat-shrinkable sealing protection materials for the helicopters is achieved.

Description

technical field [0001] The invention belongs to the technical field of sealing and protecting materials for helicopters, and in particular relates to a method for verifying the application of multi-series heat-shrinkable sealing and protecting materials for helicopters. Background technique [0002] Wires and cables are widely used in aviation equipment, especially helicopters. The wires and cables used in the whole aircraft are a systematic project. Once there is a problem, it will affect the realization of the normal functions of the helicopter and the electromagnetic compatibility of each system and even the whole aircraft. In order to achieve the functional requirements of the whole machine wire and cable system for protection against complex environments such as wear resistance, insulation, corrosion resistance, and medium resistance, it is necessary to use it in the aspects of wire labeling, wire end processing, plug seat assembly, cable production, and cable installati...

AI Technical Summary

Problems solved by technology

[0003] The rational application verification of multi-series heat-shrinkable sealing materials in helicopter equipment is crucial. At present, there is a lack of application evaluation methods, data and comprehensive assessment data in China, and it is difficult to accurately and quantitatively compare and study various heat-shrinkable sealing materials in the helicopter service environment. performance

At present, the application verification of multi-series heat-shrinkable sealing and protective materials for helicopters is still in a blank stage.
