Itching to test your electric airplane’s cross-country capabilities?  A new Pulitzer Electric Air Race of over 1,000 nautical miles (1,150.78 statute miles to be exact) between Nebraska and North Carolina will show who has the fastest electric flying machine. Jim Moore, reporting for the Aircraft Owners and Pilots Association (AOPA), shows the connection between the original Pulitzer Trophy and today’s electric competition.  “Five of the first six pilots to have their names engraved on the Pulitzer Trophy were military airmen clocked around a closed course at speeds starting at 157 mph in 1920, up to a blistering 248 mph by 1925. The trophy was created to inspire innovation, and particularly faster airplanes. That vintage trophy housed at the Smithsonian National …

Electrifly-in, formerly the Smartflyer Challenge, is on for September 11 and 12, 2021, in Grenchen, Switzerland.  The event, even held in 2020 despite the pandemic, is a compact showing of the latest in electrical aircraft and technology.  Watch as this 2019 video as a Φnix (the Greek letter phi + nix –a clever bilingual pun) takes off, circuits the area and makes a landing – all the time flying with other electric aircraft. In this flight, you can see the compact airport (including a grass landing strip) and a lovely setting for a great event.  Started as the Smartflyer Challenge* in 2016, the gathering has changed its name to be more inclusive. Last year, even with travel limitations imposed worldwide, …

Two Hydrogen-Powered Aerial Vehicles

Two very different hydrogen-powered aerial vehicles have come to our attention, each with a different mission, but both with endurance and range as primary functions.  Both use a fairly straightforward fuel cell/motor arrangement to power their flights. Vicor/DMI Fuel Cell Drones Doosan Mobility Innovation (DMI) is a major drone manufacturer, and their largest products push against the FAA’s 55-pound (24.97-kilogram) weight limit.  Their DM30, powered with a DS30 fuel cell and a 10.8 liter H2 tank weighs 21 kilograms and can carry a five kilogram (11 pound) payload.  Carrying a full payload may require using the smaller seven-liter tank. Alessandro Mascellino, writing in EE Power, describes recent combination of resources that makes long-range drone deliveries possible.  “The first machines built …
