Abstract

See full text

A trip strip having a saw-tooth configuration that has application for cooling flow channels in a blade of a gas turbine engine. The saw-tooth configuration is defined by trip strip sections positioned end-to-end, where a leading edge of a trip strip section has a lower height than a trailing end of the trip strip section, and where the next trip strip section having the lower height leading edge disrupts the vortex created by the preceding trip strip section so that its size is reduced.
