Experimental and Numerical Investigation of Aerogel Based Insulation Material for Aerospace Applications

It is extremely important to meet thermal insulation requirements in aircraft to ensure appropriate operational conditions, maintain structural integrity, and achieve energy savings and cost savings. In particular, it is critical to keep the external surface temperature of the pipelines through which hot gases or liquids pass at a certain level so that the aircraft operates under optimum temperature conditions. Silica-based aerogels, which are frequently used to provide this requirement, are high-performance thermal insulation materials. In this study, the operational performance and suitability for aviation of a composite insulation blanket containing aerogel was examined by using experimental and numerical methods.
