Abstract
In this article, the process of electric machine development for aircraft with hybrid propulsion system is considered at all development stages: From the formation of technical task to the bench tests. Electric generator power of 400 kW and rotational speed of 12 000 r/min intended for aircraft with hybrid propulsion system passenger capacity of 9–19 seats was used as an example. The most problematic places and possible solutions are identified. The problems that can be revealed from each design part are considered and its influence on the entire development process is analyzed. We analyzed the influence of technological parameters in the prototyping on the accuracy of computer simulation. We also described the accident that occurred during the testing of the experimental sample, analyzed the causes of its occurrence and identified the consequences.
