초록

A buffer zone disposed between the TOBI (tangential on-board injector) discharge cavity and the forward rotor cavity of a gas turbine engine serves to maintain the TOBI air relatively pollutant free by judiciously controlling the flow to maintain the pressure of the buffer cavity below the adjacent cavities. The buffer cavity air and the forward rotor cavity air are bled to the dead rim area of the turbine rotor disk through tangentially oriented discharge ports formed in the circumferentially spaced plenums formed in the stator support. Plates on the bo...
