Speaking at the first annual Sustainable Aviation Symposium at the Sofitel San Francisco Bay on May 6, 2016.  Dr. Joseph Kallo focused on hydrogen as a more than potential fuel for future flight.  He stressed that H2 fuel development was further along than one would think, and shared several examples to promote that thought. A Busy Man, a Storied Airframe Dr. Kallo is DLR (Deutsches Zentrum für Luft-und Raumfahrt – German Center for Air and SpaceTravel) Coordinator of Electrical Aviation for Germany’s equivalent of NASA, oversees work at the DLR Institute of Engineering Thermodynamics, which has worked with Pipistrel in Slovenia to convert the Green Flight Prize winning Pipistrel G4 to the hydrogen-powered HY4. He’s also Institute Director at the …

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 …

EAS VIII: Klaus Ohlmann Conquers Everest

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 0 Comments

Klaus Ohlmann says the sailplanes and solar-powered aircraft in which he has set several world records are powered by a “gravitational engine with an external fusion reactor.”  He has been on a sun-stoked roll the last few years.   His recounting of the epic journey first to fly a Stemme motorglider from Germany to Katmandu, and then to conquer Mount Everest in a sailplane, kept the eighth annual Electric Aircraft Symposium audience enthralled.  That feat alone would be enough for admiration, but his seemingly never-ending series of adventures provoke a bit of awe. He is a member of the Mountain Wave Project (MWP), a group which explores high-altitude weather systems to verify theoretical considerations.   As stated in the MWP’s web site, …

Being Led By The Nose

With speculation in CAFE circles about the use of thin, lightweight motors now available for landing and takeoff augmentation, it comes as almost now surprise that DLR, the German Aerospace Centre, and the Airbus people at EADS have announced development of an electric nose wheel that could replace airport tugs and extended ground operation for airliners’ jet engines. According to The Engineer, a British publication, a fuel cell-powered system delivers electrical energy capable of powering the nose wheel of a 70-ton aircraft.  “Commercial aircraft could cut their on-ground emissions by one quarter with a new hydrogen fuel-cell propulsion system, according to its creators. “For short-haul aircraft that often take off and land seven times a day, this could save between 200 …

ENFICA-FC – A Speed Record for Hydrogen

Dean Sigler Electric Powerplants, Sustainable Aviation 3 Comments

Professor Guilio Romeo of the Politecnico de Torino, Italy is a man of many firsts.  Last year, his team fielded Skyspark, a Pioneer 300 powered with an electric motor fed by batteries.  This year, in a totally new development, Professor Romeo coordinated the activities leading to a successful hydrogen-powered electric aircraft, and set a world speed record to top off that accomplishment. The Skyleader 150 Zero CO2 light sport aircraft, built by JIHLAVAN airplanes, Ltd. in the Czech Republic, was fitted with Intelligent Energy proton exchange membrane (PEM) fuel cells from the United Kingdom, an inverter and power management system by Italy’s Mavel Elletronica, and a motor at least partially designed by the University of Pisa, Italy.  Tanks and a high-pressure fuel …
