ABSTRACT:
A system for protecting the strut and wing structure of an airplane from high temperatures proximate the exhaust nozzle end of a jet engine employs a set of outer spring metal fingers attached to the exhaust nozzle outer sleeve and which bear against the strut structure, and a second set of inner spring metal fingers, interleaved with the first, which close off interfinger slots in the first or outer set whereby to maintain firewall integrity. Hot gases are thereby prevented from passing forwardly into the strut structure and wing area so as to protect the same in the event of an engine fire.
