T-stage Knowpia

T-stage is a British term for a compressor used in a particular concept for a variable cycle combat engine. The T-stage is part of the HP rotor in this concept.^[1]

A US concept for a variable cycle combat engine also uses a similar compressor arrangement as part of the HP rotor. It is called a core driven fan stage (CDFS) by General Electric Aviation in their Variable Cycle Engine (VCE) which ran in 1981.^[2]

Alternative concepts including an LP driven stage are shown in the US patent "Variable Cycle Gas Turbine Engines" filed in 1975.^[3]
