ABSTRACT:
An open circuit liquid cooled gas turbine in which a coolant passes through the turbine blades and is expelled at the tips thereof. The coolant is recaptured by providing ports in the turbine casing in radial alignment with the turbine blades whereby fluid expelled radially is received by the ports. A trough is provided in the turbine casing axially displaced downstream from the turbine blades to recapture coolant that is blown by the ports due to the differential pressure in the turbine.
