Studies on Fire Protection Scheme for Engine Bulkhead of HANSA-3 Prototype Aircraft


The firewall used in Hansa - 3 Prototype I1 is a stainless steel of 0.4 mm thickness. JARVLA requirement on the firewall is that a stainless steel be atleast of 0.38mm thickness. Behind this firewall there is an engine bulkhead made of plywood of 8mm thickness and of fire resistant quality, covered on either side by 2 layers of bidirectional glass cloth with epoxy resin system of aircrafk quality.
