A wall structure for a gas turbine engine combustor has an inner wall and an outer wall defining a duct. The duct diverges as it extends in the general direction of fluid flow within the combustor. Cooling air is fed into the duct through angled cooling holes which provide a film of fluid over the outer wall of the combustor should the inner wall be eroded because of the high temperatures in the combustor. |
