Helios Horizon Aims for New Highs

Dean Sigler Announcements, Batteries, Electric Powerplants, Sustainable Aviation Leave a Comment

Altitude records are tricky.  Aiming for new heights requires careful definition of one’s launch points, means of elevating oneself, and apparently adherence to a tightly defined set of rules.  Helios Horizon set some new altitude records last year, and hopes to reach even higher soon.  Its eventual goal is to fly “into earth’s stratosphere”– in an electric aircraft. Records at Altitude – and Speed This might seem like a bit of a step down for Miguel Iturmendi, the founder and test pilot for the Helios Horizon project.  He’s already been to 65.605 feet (19.9 kilometers) in Perlan II, on August 28, 2018.  As the Saratoga Times notes, the flight hit “The fastest known speed of Mach 0.48—roughly half the speed of sound—in a glider over El Calafate, Argentina, which earned him and his team the Society of Flight Test Engineers’ James S. McDonnell Award, as well as a Triple Lennie Pin (an aviation award for soaring named for the lenticular clouds …

A Pulitzer Written in the Sky

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 Air and Space Museum will be engraved with its first new name in 97 years in 2022, following completion of a 1,000-nautical-mile cross-country race by up to 25 electric aircraft.” Ralph Pulitzer was son of Joseph Pulitzer, whose prizes for …

Firefly Flies with New Motor and Who Knows What Else?

Jean-Luc Soullier and Roman Marcinowski forge ahead on two fronts to set electric flight records.  Longer term, we hope to see first flights of their motorized Windward Performance Duckhawk, modified for long-distance flights and a crossing of the Atlantic Ocean – perhaps as early as next year. In the meantime, they are putting the finishing touches on their already record-setting Colomban MC-30 Luciole (Firefly), now with its third motor, significantly larger and more powerful than previous powerplants.  Making an initial test flight on October 30, Jean-Luc managed an impressive climb rate, even at partial power. Last year, the team stated their hoped-for records to come. Our next targets are : Spring/Summer 2014 New FAI world records : – Speed : minimum 200 Km/h (124 mph) – Distance : minimum 2,000Km ( 1,250 miles )  (This will probably be accomplished with the Duckhawk.) – Altitude : minimum 10,000 meters ( 32,800 Ft ) (Again, probably with the Duckhawk, although Roman says, “let’s see what …

Chip Yates’ Records Ratified by FAI

With recognition this week of five electric airplane records set by Chip Yates in flights last year, the Fédération Aéronautique Internationale (FAI) and the National Aeronautic Association (NAA) ratified performance numbers that top those of most single-engine high-performance gasoline-powered aircraft from established manufacturers, according to Yates.  Your editor was on hand for the California Capital Airshow last October to see Chip take his Long-ESA to 500 meters (1,640 feet) from a standing start in only 62.58 seconds, 17 seconds faster than the previous record set by a fossil-fuel burner. The new records were really set last year between September and November and have just been ratified. They include an altitude of 4,481 meters (14,701 feet), a time to climb to 3,000 meters (9,840 feet) of five minutes, 32 seconds, and maintaining an altitude of 4,439 meters (14,564 feet) in horizontal flight.  Chip achieved two speed records, reaching an average of 324.02 kilometers per hour (201 mph) in four passes over …

An Electric Altitude Record in Short Sleeves

Dean Sigler Electric Powerplants, Sustainable Aviation 1 Comment

Gary Davis of Greenville, South Carolina set a world altitude record for electric trikes, about the simplest of powered flying machines.  His flight to 4,790 feet above mean sea level (under 4,000 feet above ground level) exceeded his hope to reach at least 1,000 meters (3,280 feet) and puts him and power system provider Randall Fishman in the record books, at least when the Federation Aeronautique Internationale (FAI) ratifies the numbers. Davis, a managing director in Nachman Norwood & Parrot Wealth Management Consultancy in Greenville, has that affiliation discreetly emblazoned on his North Wing Stratus wing.  The company, possibly because of Davis’s interest, has 25 kilowatts of solar panels helping power its offices, and Davis and wife Deborah Meadows both drive electric cars.  In a telephone interview, he pointed toward Greenville as the home of Prottera electric buses, a point of local pride. He explained the simple flight profile he maintained, a quick takeoff, steep climb and circling in thermals …
