ABSTRACT:
A turbine (18) of a gas turbine engine includes erosion energy dissipaters (44) which comprise of a plurality of inlet orifices (46) and a large diameter outlet orifice (48). The erosion energy dissipater reduces erosion of associated structure due to impingement of particulates entrained in airstreams. Various construction details are described to provide cooling air containing entrained particulates to the high pressure turbine case of a gas turbine engine without eroding the case.
