MAHEPA (Modular Aproach to Hybrid-Electric Propulsion Architecture) is a European Union project to build emission-free aircraft.  A public flight of Pipistrel’s HY4 hydrogen-powered, four-seat aircraft was the latest demonstration of the group’s progress. Challenging Objectives Overall, MAHEPA hopes to accomplish five objectives: Advancing the fuel-driven serial hybrid-electric Powertrain which uses a lightweight internal combustion engine (ICE), capable of running multiple fuels as the power generation module. Advancing the reliability of zero-emission serial hybrid-electric powertrain which uses a Proton Exchange Membrane (PEM) Hydrogen Fuel Cell (FC) as the power generation module. Advancing new airborne qualified, lightweight, high-power density components such as a 200 kW+ electric motor, a 100 kW+ generator and improved power electronics using Silicon Carbide (SiC) technology to increase …

G4 to HY4 – Swapping Batteries for Fuel Cells

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 …
