초록

A convectively cooled turbine blade has two distinct cooling air passage systems. The first system cools the blade leading edge and emits cooling air through outlet passageways in the leading edge arranged in showerhead array. The second system includes a five-pass series flow passage comprising five cooling passage sections that extend in series through the remainder of the blade. Cooling air resupply passages inject additional cooling air into the third and fifth cooling passage sections.
