COMBUSTION CHAMBER

摘要

A combustion chamber comprises an outer wall and an inner wall. The outer wall has mounting apertures extending there-though and the inner wall has threaded studs extending there-from. The threaded studs extend through the mounting apertures in the outer wall. Cooperating nuts locate on the studs. Walls are positioned between the outer wall and the inner wall. Each wall is spaced from and extends around a respective fastener to form a chamber around the respective fastener. Apertures extend through the outer wall. Each aperture is spaced from a respective mounting aperture. Each aperture allows a flow of coolant into the associated chamber and around the associated fastener to cool the fastener. Each wall has an opening at a position diametrically opposite to associated aperture to allow the flow of coolant out of the chamber to a space between the outer wall and the inner wall.

1. A combustion chamber comprising an outer wall and an inner wall spaced from the outer wall,
the outer wall having at least one mounting aperture extending there-through, the inner wall having at least one fastener extending there-from, the at least one fastener on the inner wall extending through a corresponding mounting aperture in the outer wall, a cooperating fastener locating on the at least one fastener extending through the corresponding mounting aperture, at least one wall being positioned between the outer wall and the inner wall, a corresponding wall being spaced from and extending around the at least one fastener to form a chamber around the at least one fastener, at least one inlet opening to allow a flow of coolant into the chamber and at least one outlet opening to allow a flow of coolant from the chamber, wherein the at least one inlet opening and the at least one outlet opening being circumferentially spaced apart with respect to an axis of the at least one fastener and/or the corresponding mounting aperture to allow a flow of coolant circumferentially around the at least one fastener.
