The article presents the results of study conducted on a microturbogenerator with nominal power 1 kWe. One primary objectives was to determine maximum for several preset and constant flow rates HFE-7100 working medium. During tests, variable parameters were heat source electrical load microturbine generator. Such methodological approach made it possible experimental mechanical characteristics high-speed microturbogenerator, which are practically absent in subject literature at present. shows that, medium rate, there exists an optimum level microturbogenerator's output is maximum. It determined that also depends value At minimum tested rate 30 g/s, approx. 210 We obtained 12 kWt resistive 6.4 Ω. On other hand, same 14 kWt, approximately 205 W. 60 625 W achieved 18 kWt. found current generator had major influence microturbogenerator.
