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 efficiency of power transmission due to decreased switching losses. Developing “common building blocks” solutions also for different aircraft configurations, enabling the proliferation of powertrain modules between various aircraft. Gathering, analyzing and comparing in-flight performance and emission data in order to …
