Abstract: Flame arrestor to cover aircraft engines made up of one ventilation wire grid (6), one upper metallic plate (9) where wire grid sits (6) on the edges of a circular hole (10) and a wall (25) which is located next to a chamfer (26) placed at the edge of a central hole (5) existing in the platform (3). On the lower side of the thin composite wall (25) there is a flange cylinder formed by a disc (15) a cylindrical ring (14) coinciding in height with the chamfer (26), creating an interior cavity (27) where gases are conducted and accumulated. All these elements are joined together by some bolts (22) that go through them and finish with a lower metallic plate (12) and an octagonal shaped part (19) separated by a specific distance established by the appropriate elements like bushing or spacer.

Abstract: Flame arrestor to cover aircraft engines made up of one ventilation wire mesh (6), one upper metallic plate (9) where wire mesh sits (6) on the edges of a circular hole (10) and a wall (25) which is located next to a chamfer (26) placed at the edge of a central hole (5) existing in the platform (3). On the lower side of the thin composite wall (25) there is a ring (16) with outer flange whose width coincides with that of the wall, and another flanged ring (14) coinciding in height with the chamfer (26), creating an interior cavity (27) where gases are conducted and accumulated. All these elements are joined together by some bolts (22) that go through them and finish with a lower metallic plate (12) and an octagonal shaped part (19) separated by a specific distance established by the appropriate elements.
