Abstract
The spreading of a fire outside of an aircraft body into the cabin through the windows is retarded by a fire retardant slide member that is movable into a window covering position guided by guide rails or the like. Both, the sliding member and the guide rails are made of fire retarding material such as thermosetting material, preferably glass fiber reinforced thermosetting materials. A thermoplastic locking element that holds the sliding cover member in a recessed position releases the cover member when the locking element melts at elevated temperatures to cover the window automatically, e.g. with the aid of gravity or with the aid of one or more biasing springs.
Claims20
A device for retarding the spread of an external fire into an aircraft cabin through a cabin window in an aircraft body wall, comprising a window area covering slide member made at least partly of fire retardant material, a guide arranged along sides of said window for guiding a movement of said slide member between a removed position and a window covering position, said guide also being made substantially of fire retardant material and an automatic release member for operating said fire retardant slide member into a fire retarding, window area covering position.
A device for retarding the spread of an external fire into an aircraft cabin through a cabin window in an aircraft body wall, comprising a window area covering slide member made at least partly of fire retardant material constructed as a layered structure, a guide arranged along sides of said window for guiding a movement of said slide member between a removed position and a window covering position, said guide also being made substantially of fire retardant material, a mechanism for operating said fire retardant slide member into a fire retarding, window area covering position, wherein said layered structure of said slide member comprises two cover layers made of glass fiber reinforced phenolic resin and a central core layer made as a honeycomb structure with core elements having a hexagonal cross-section.
