Pipistrel, itself flying pure electric and hybrid aircraft, has announced its participation in MAHEPA, a Modular Approach to Hybrid-Electric Propulsion Architecture.  MAHEPA aims to,” reduce the gap between research and the production of low-emission propulsion technologies that would enable the achievement of environmental objectives in the field of aviation by 2050.”  Mahepa’s first meeting, held May 15 and 16 at Pipistrel’s headquarters at Ajdovscina (Slovenia), helped define the direction for a major academic/industry project. Led by the aircraft manufacturer, in cooperation with Compact Dynamics, DLR (Germany’s equivalent of NASA), the University of Ulm, H2Fly, Politecnico di Milano, TU Delft and University of Maribor, project goals are impressive. – “To boost research in the field of low emission propulsion technology to …

HY4 Makes First Public Flight – Your Editor Rides EAA’s Ford Trimotor

A day after Pipistrel, the DLR and associates flew the first public demonstration of their four-seat hydrogen-powered HY4, your editor and a friend took a brief hop around the Aurora State Airport in Oregon in EAA’s Ford Trimotor, the first certified airliner in America.  The two events, roughly equal in duration, if not in historicity, demonstrate a readily observable progress in aeronautics. A quickening of design and technology 14 years after the Ford 5AT first flew on a scheduled route that took 51 hours total time to cross the United States (and split transport duties with trains), your editor’s father was whisked nonstop by Army Air Corps C-54 across the Atlantic to Shannon, Ireland, and then to Bobbington and Newquay, England …

G4 to HY4 – Swapping Batteries for Fuel Cells

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 0 Comments

The University of Stuttgart and Pipistrel started down similar paths around 2007, with the Stuttgarters attempting a hydrogen-powered two-seat aircraft, the Hydrogenius; and Pipistrel developing a self-launching craft with either two-stroke power or an equivalent electric motor. The two groups came to rely on one another, with hydrogenius using the forward fuselage and wings of the Taurus G2 with hydrogen tanks in the fuselage and a Sineton motor on the tail.   On February 27, 2008, Professor Rudolf Voit-Nitschmann, the father of the solar powered aircraft Icare 2 and the unofficial World Record holder for distance flown in a solar powered aircraft, along with dipl. ing. Steffen Geinitz and dipl. ing. Len Schumann met with Pipistrel leaders, including CEO Ivo Boscarol and …
