Shown at the E-Flight Expo at Friedrichshafen’s Aero 2015, Stuttgart University’s e-Genius had an aerodynamic-looking pod next to one wing, containing an ENGIRO range extender consisting of a Wankel-type engine and a generator.  The unit could, as its name implies, help e-Genius go for new records to add to its already significant collection. Bill Lofton at EV Hangar has detailed the extender, now associated with the e-Genius and in a larger variant on the Equator P2 amphibian being built in Norway by Tomas Broedreskift. Equator’s web site describes its power system: “The hybrid propulsion system being developed by Equator is called EHPS (Equator Hybrid Propulsion System). The engine specific project is being co-funded by Transnova and the company doing the development work …

A Hybrid Motorized Ultralight Sailplane

Dr. Paul Robertson of the University of Cambridge has been sorting out the necessary components and relationships to make hybrid-electric-gasoline aircraft a practical reality for the last several years.  His Photonics and Sensors group at the University researches many areas of optics and electronics, including holography and “nano-photonic structures,” with hybrid flight last on the long list of studies.  The blog has been reporting on his aeronautical activities since 2009, including what turned out to be the second and third electric aircraft flights in England, and the first flight of an electric-gas hybrid in a modified Alatus motorglider. The current aircraft uses larger power components and is a bit more sophisticated.  In fact, an external view would not give away …
