The further development of the gasturbine in the direction of gas temperaturs in excess of those of present day military aircraft is worth the effort, because the volumetric poser density, as well as the power density in relation to the mass, can be considerably increased. The compact construction, together with the decrease of the specific fuel consumption, permits even greater ranges for fast ships and for all types of heavy-duty vehicles. Cooling the gasturbine with liquid metal is, for high gas temperatures, considerably superior to the 'classic' air-cooling method. Combined systems, for example with liquid metal cooling in the high pressure turbine and air-cooling in the lower stages, are of course possible, but were not investigated here. Because full load operation is usually only for short periods of time, the cooling channels should be partially or totally blocked during partial load operation. An optimization study shows, within the frame of a generally improved gasturbine, how power density and range can be balanced. (DePo)
