Manufacturing process and raw materials of bearing windshield

Abstract

The windshield is an important part of the aircraft structure. In addition to providing a clear driving vision for the driver, it also needs to have certain strength and stiffness performance to meet the pressurization static load and impact dynamic load. At the same time, the windshield glass also needs to have a certain function of heating, anti-icing, and defogging. According to the application scenarios, the windshield can be divided into two types: bearing windshield and non-bearing windshield. Due to the requirement of weight, appearance, and security of the bearing windshield, it will become the mainstream design trend in the future. However, bearing windshield is composed of a wide variety of raw materials with different performances, the manufacturing process is complex, and the research and development verification tests are difficult. This paper introduces and summarizes the main difficulties and index requirements of the bearing windshield in terms of structural design, manufacturing process, and raw materials, and provides guidance and support for the subsequent airworthiness compliance verification of the bearing windshield.
