The HYPSTAIR project deals with components design of a serial hybrid propulsion system for a small aircraft. A serial hybrid aircraft concept currently presents the best efficiency versus range compromise in the light aviation segment. It can be considered as an electrically powered aircraft, with an on board generator used for extending the range when necessary.

The project will involve conceptual design of the hybrid propulsion system components, namely the generator, motor, inverter, batteries and control unit. The components will be sized and designed considering the performance and energy efficiency of the complete airframe-propulsion system, and will be tested in a laboratory environment. Designed dedicated human-machine interface will allow simple operation of a complex hybrid system. Together with the reliability of electric motors and the use of dual energy sources, safety of flying as provided by a system built upon these components will be improved.

All the components will be designed in a way that they will meet the relevant safety and certification standards. As there currently exist no regulations for aviation hybrid drive systems, defining these in collaboration with the authorities will be an important contribution of the project, paving the way for hybrid and electric technologies to be introduced to the market. These efforts will help to create a competitive supply chain for hybrid drive components and reduce the time to market of such innovations.
