Cranfield, England and its local university are hubs for electric aircraft development.  Dr. Guy Gratton is test flying The Light Aircraft Company’s eKub on 48-Volt battery power, ZeroAvia is crafting a Dornier 228 to run on hydrogen, and now Cranfied Aerospace Solutions (CAeS) is readying a Britten-Norman Islander for H2-powered flight in 2023. The Islander Living up to its name, Britten-Norman’s Islander seems to be busy worldwide island hopping.  The twin-engine plane ever makes the world’s shortest scheduled flights, including this between Juist to Norden across the Wadden See.  The 74-second flight is less than the time spent taxiing at the beginning and end of the hop. Designed and developed in the 1960s, 750 Islanders of the 1,280 built are …

A (Partially) Steam Engine in the Sky?  Pratt & Whitney announces that it, “Has been selected by the U.S. Department of Energy (DoE) to develop novel, high-efficiency hydrogen-fueled propulsion technology for commercial aviation, as part of DoE’s Advanced Research Projects Agency-Energy (ARPA-E).” Their press release continues, “The Hydrogen Steam Injected, Inter‐Cooled Turbine Engine (HySIITE) project will use liquid hydrogen combustion and water vapor recovery to achieve zero in-flight CO2 emissions, while reducing nitrogen-oxide (NOx) emissions by up to 80 percent and reducing fuel consumption by up to 35 percent for next generation single-aisle aircraft.” P&W claims their HySIITE engine’s steam injection will “dramatically reduce” nitrogen oxide emissions, a greenhouse gas.  “The semi-closed system architecture is claimed to have thermal efficiency …

Eviation’s Alice and MagniX’s motors got a visit from the Governor of Washington State and the Mayor of Arlington where the nine-seat airliner is being prepared for its first flight.  Electric aircraft, so far, don’t command that big a portion of the daily press, so it’s heartening to see TV cameras and news reporters turn out. Eviation shared its take on Facebook.  “We enjoyed hosting @GovInslee and @barbtolbert today for an intimate look as Alice prepares for first flight later this year. They saw first-hand how our growing teams are working to make #electricaviation a reality.” Governor Jay Inslee was already aware of the work motor company MagniX was doing when he acknowledged the May 28, 2020 flight of a …
