A Reexamination of the Gas Turbine - Torque Converter Power Transmission Unit

The combination of the free turbine gas turbine engine and the hydraulic torque converter was reexamined. A non-dimensional matching procedure is proposed and non-dimensional results are presented; both of which facilitate comparative analyses. The effects on system specific fuel consumption and heat rejection are discussed. An optimum power unit combination is suggested.

The Appendix illustrates how non-dimensional matching may be performed.
