First Claim
1. A pressure relief assembly (24) comprising:
- an aircraft engine cowl (26) including radially outer and inner skins (28,30) having an opening therethrough;
a door frame (32) fixedly joined around the perimeter of said opening and extending laterally therefrom to define a door seat (34) surrounding a central portal (36) and facing radially outwardly;
a pressure relief door (38) pivotally joined to said cowl (26) for being deployed outwardly from a stowed closed position covering said portal (36) to a deployed open position uncovering said portal (36);
said door (38) having radially opposite inner and outer surfaces (40,42) terminating in a perimeter rim (44), with said inner surface of said rim (44) overlapping said door seat (34) to define a primary seal (46) in said door stowed position; and

Abstract
A pressure relief assembly (24) includes an aircraft engine cowl (26) having radially outer and inner skins (28,30) having an opening. A door frame (32) is joined around the perimeter of the opening and defines a door seat (34) surrounding a central portal (36). A pressure relief door (38) is joined to the cowl (26) to cover the portal (36). The door (38) has inner and outer surfaces (40,42) terminating in a perimeter rim (44), with the inner surface (40) of the rim (44) overlapping the door seat (34) to define a primary seal (46) with the door stowed closed. A fireproof secondary seal (48) bridges the door inner surface (40) and frame (32) around the inner perimeter of the primary seal (46) to pre-seal flow to the primary seal (46).
