This paper presents the design and experimental research of a scaled-size prototype of the high-temperature starter-generator for more electric aircrafts. A computer model of the prototype with a high accuracy and good convergence with the experimental results was designed. In addition, the cooling efficiency evaluation was carried out; the losses in starter-generator active parts were estimated. Based on the results of experimental research and computer simulation, the full-size starter-generator was designed. It is important to notice that the full-size starter-generator was less loaded in terms of electromagnetic and thermal loads. This shows the proposed method efficiency. The obtained mass properties of the full-sized starter-generator is less than the 10 kg Thales’ starter-generator. This proves the efficiency of the researched variant.
