Integral refilmer lip for floatwall panels

摘要

A refilmer for the combustion/dilution air hole of a floatwall panel of the combustor of a gas turbine engine carries a 180 DEG lip extending in, the hot gas stream of the combustor having a projection projecting in the combustion/dilution air hole to divert a portion of the air stream to form the film on the inner surface of the segmented panel. The refilmer is formed integrally with the segmented panel and carries a shoulder bearing against the inner surface of the shell defining a spacer. Forming the combustion/dilution air hole integrally with the segmented panel allows the air hole to be located in any efficacious location for effectuating optimum combustion.
