Evolaris – aerobatics with an electric motor

Imagine turning pirouettes in a stunt plane in the sky with no noise or emissions! The stunt plane with an electric motor first saw the light of day as two students’ bachelor’s thesis, and is now being developed by the BFH spin-off Evolaris.

The Project

The idea of developing an all-electric drive for powered aerobatics had been buzzing around in the minds of the founding members of evolaris for quite some time. The two students from Bern University of Applied Sciences were finally able to put their idea into practice in the form of a bachelor’s thesis.

This led to the founding of evolaris aviation in spring 2015 as a spin-off from Bern University of Applied Sciences. The purpose of the evolaris association is to develop and build an electrically powered aerobatic plane. They are aiming to provide general aviation with a new propulsion system to replace conventional combustion engines. They also want to reduce noise and exhaust emissions for the benefit of both people and the environment.

evolaris aviation has set itself the goal of developing and commercialising high-tech electric propulsion systems for single-engine aircraft. The development of a high-performance electric motor and electrical system plus a battery and charger are the first steps in this direction.

The model VOTEC EVOLARIS from MSW Aviation proved to be a suitable aircraft for the first application. With the new evo220 high-performance electric motor, the aircraft is propelled by a veritable power-pack. Besides noise and exhaust emissions being significantly reduced, the VOTEC EVOLARIS is also impressive for its markedly lower energy and running costs. The energy for the new aircraft is supplied by the charger developed by evolaris, the 44kW Supercharger, with a maximum charging capacity of 44kW. The device can be operated with simple, standard adapters with CEE 16A, 32A and 63A current from a regular electrical socket. Besides the VOTEC EVOLARIS aircraft, it can be used to charge any electric car with a CCS connection.

Going forward, evolaris also hopes to be able to offer electric aircraft engines in the power range from 80hp to 400hp – for new aircraft designs, but also for conversions of combustion-engine powered planes.
