Abstract:
1. A fire protection apparatus for an aircraft engine air-cooled heat exchanger located in a compartment, the heat exchanger having an air-entry inlet facing the compartment and a flammable fluid contained therein, the fluid being pressurized during engine operation, the fire protection apparatus comprising: a cover mounted adjacent the heat exchanger and moveable between at least an open position and a closed position wherein the cover substantially covers the air-entry inlet and thereby adapted to at least partially block flames in the compartment from directly impinging the heat exchanger; and a cover-moving assembly adapted to move the cover between the open and closed positions, the cover-moving assembly communicating with pressure of said fluid inside the heat exchanger, said pressure providing a primary moving force to the cover-moving assembly.
