A university in Poland has conceived, built and tested – but not flown, the AOS-H2, a hydrogen-powered motor glider. In 2013, the blog covered the test flights of a battery-powered electric two-seat motorglider designed at the Warsaw (Poland) University of Technology. Now, a similar design, the AOS-H2 has been crafted to fly on power generated by a hydrogen fuel cell. Early tests in 2020, “Confirmed that all units work correctly.” The “Hybrid Propulsion System Based on Hydrogen Fuel Cells in a Light Aircraft” is funded under the “Applied Research III” Program by the National Centre for Research and Development. Professor Marek Orkisz Ph.D., D. Sc., Eng. Of the Rzeszów University of Technology is Program Manager. As noted in the University’s announcement of the new airplane in 2020, “The last completed project was the AOS-71 motor glider fitted with an electric-powered propulsion system integrated in the fuselage and powered by lithium-polymer batteries in the wings.” At that time, Mike Friend, former …
