Researchers at Universidad Carlos III de Madrid and AXTER Aerospace have created an electric aircraft engine that can be installed in conventionally powered light aircraft. This engine is designed to both increase power and also expand range, crucial in the event of an engine failure.
The electric engine can be coupled to the conventional engine via a conventional drive system. An automatic electronic control system allows for the electric drive motor to be automatically adjusted depending on the plane's needs. So if there's an issue with the primary engine, the electric engine kicks into gear.
While compact, single-engine aircraft are the mainstay of recreational flying, the fact of the matter is that a single malfunction can lead to dire consequences. This auxiliary electric propulsion aircraft engine makes them both safer and more enjoyable.
