Abstract

A combustion chamber (15) comprises an outer wall (50) and an inner wall (52). The outer wall (50) has mounting apertures (70) extending there-though and the inner wall (52) has threaded studs (72) extending there-from. The threaded studs (72) extend through the mounting apertures (70) in the outer wall (50). Cooperating nuts (74) locate on the studs (72). Walls (90) are positioned between the outer wall (50) and the inner wall (52). Each wall (90) is spaced from and extends around a respective fastener (72) to form a chamber (92) around the respective fastener (72). Apertures (94) extend through the outer wall (50). Each aperture (94) is spaced from a respective mounting aperture (70). Each aperture (94) allows a flow of coolant (G) into the associated chamber (92) and around the associated fastener (72) to cool the fastener (72). Each wall (90) has an opening (96) at a position diametrically opposite to associated aperture (94) to allow the flow of coolant (G) out of the chamber (90) to a space between the outer wall (50) and the inner wall (52).
