Bench tests of an electric engine-propeller group, as the first stage in the creation of a hybrid power plant

The article discusses a stand for testing an electric propulsion system and its components. The test bench was developed for the first stage of practical research on the creation of a hybrid parallel- circuit power plant based on a piston and electric motors. The engine-propeller group was created for light aircraft with an engine power of 10…20 kW. The article presents conclusions about the conducted bench tests and the operation of the stand. Further developments of an electric motor-generator set for a hybrid power plant made on the basis of bench experiments of the electric engine-propeller combination are shown.
