Gas turbines can be further developed by the use of higher temperatures, which can, in the case of ships and hovercraft, result in a more compact engine and decreased specific fuel consumption. In this optimisation study, in which the temperature in the hot section was limited to 1,200 degrees K for economic reasons, the Author (of the Technical University, Munich) shows that, where high gas-temperatures are employed, cooling the hollow turbine-blades with liquid metal (e.g., sodium) is much superior to cooling them with air in the usual way. It is also shown how, in a generally-improved gas-turbine, a balance can be achieved between specific consumption (expressed in terms of ship range) and specific power (on a basis of construction volume).
