Abstract

In an aircraft, engine firewalls refer to the structural components which isolate engine hot section and accessories section from plenum chamber and cowling refer to the outer skin of nacelle. As per the federal aviation regulation (FAR) requirement, the firewalls should be “fire proof” and the engine cowling should be “fire resistant”. This can be achieved by selecting proper material and suitable surface protection. The present work deals with design and development of a fire protection external coating scheme for a light transport aircraft (LTA) fire wall and cowling, its validation through acceptance tests and simulation (using FE software) of stiffness variation of structure due to variation of temperature-thus estimating the residual strength and integrity of structure.
