    This invention proposes an improved geometric configuration of impellers in heavy duty gas turbines. In the proposed configuration alternative impellers are extended until the gun hole inlet radius thereby reducing entry loss of flow into gun holes inlet by reducing free vortexing before the gun hole inlet. The flow...
