COOLING EFFECT OF DIFFERENT TYPES OF MATERIALS IN AN AVIONICS SYSTEM

Abstract

Equipment used in the aviation industry heats up over time depending on working conditions. It is possible to preserve the properties of equipment affected by heat by either cooling the system and returning it to initial conditions or by producing the system from materials that are not affected by heat much. One of the areas where nanocomposite materials will be used is avionic systems in the aviation and space industry. These systems are structures in which elements such as sensors, cabling and processors, which form the basis of the electronic structure of flight, are brought together in very small volumes. It is important that the material used in these structures is light and has high strength and has electromagnetic properties selected accordingly. In this study, the thermal analysis of Vapor Grown Carbon Fiber (VGCF) nanocomposite materials produced by adding them to the epoxy matrix in terms of the thermal performance of avionic boxes was carried out by comparing them with the thermal properties of the aluminum material. As a result of the findings obtained from thermal analysis studies carried out in four stages for this purpose; It was observed that by using VGCF composite instead of aluminum material, approximately 23% improvement in temperature output and 17% improvement in thermal load was achieved. Thus, it is anticipated that energy efficiency will be increased with the use of lightweight and high-strength nanocomposite materials, which is considered one of the most important goals of the aviation industry.
