Havacılık Uygulamaları için Termal Yalıtım Malzemesinin Geliştirilmesi

Öz

Hava araçlarında, uygun operasyonel koşulların sağlanması, yapısal bütünlüğün korunması, enerji tasarrufu ve maliyet konularında kazanım sağlanması için termal yalıtım isterlerinin sağlanması son derece önemlidir. Özellikle, sıcak gaz veya sıvıların geçtiği boru hatlarının dış yüzey sıcaklığının belirli bir seviyede tutulması ve böylece hava aracının optimum sıcaklık şartlarında faaliyet göstermesi kritiktir. Bu isteri sağlamak için sıklıkla kullanılan silika bazlı aerojeller yüksek performanslı ısı yalıtım malzemeleridir. Bu çalışmada, aerojel kullanarak elde edilen kompozit bir yalıtım battaniyesinin deneysel ve nümerik olarak çalışma performansı incelenip havacılığa elverişliliği irdelenmiştir.

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

Öz

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.
