Red Bull Does Give You Wings

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

Red Bull, worldwide distributor of energy drinks, is good at putting on a show.  From their dramatic Hangar 7 museum, art gallery and five culinary outlets in Salzburg, Austria to their extravagant displays of derring-do, Red Bull lives large.  Their largesse is doled out in an incredible museum, gourmet feasts, and stunning acts of aerial derring-do. Hangar 7 houses pristine restorations of historic aircraft and Formula 1 race cars, an ever-changing selection of artworks, and restaurants, a bar, and cafes, all within a light-filled, glass-walled edifice.  Entrances to the Hangar remind your editor of depictions of wing lift curves seen in aerodynamic textbooks. And this video doesn’t even include the Museum’s magnificent Lockheed Constellation, or a glimpse of the five restaurants and cafe’s on site.  One of the best parts of visiting Hanger 7 is that parking and admission are free.  This is a true gift for fans of aviation history and Formula 1 racers, and enables one to enjoy …

XPrize for Drones Spotting and Fighting Fires

Dean Sigler Announcements, Autonomous Aircraft, Electric Aircraft Components, Electric Powerplants, Sustainable Aviation Leave a Comment

A Firefighting Competition Like No Other Xprize has given us budget space travel, hyper-economical cars, and attempts to replicate the medical functions of Star Trek’s Tricorder.  Now, the XPrize folks have turned their attentions to spotting and controlling wildfires by drones.  This fits well with the Sustainable Aviation Foundation (underwriting this blog) and its concerns about spotting and controlling wildfires at the earliest opportunity. To counter this, XPrize has launched an $11 million comptetiton to, “Protect lives, forests, and the climate: Create breakthrough technologies that detect and extinguish destructive wildfires, enabling a future where people and healthy fire can safely coexist.”  This challenge, promoting autonomous flight vehicles and the ability rapidly identify and extinguish incipient wildfires, initially drew 338 teams.  These have been culled to 15 semifinalist groups. The Semifinalists This worldwide problem drew worldwide interest.  The 15 teams are: Aerowatch of Barcelona, Spain Agni  part of TRID Systems in Dresden, Germany Anduril, in Costa Mesa, California Crossfire, College Park, Maryland (see …

Pulitzer Trophy Race 2025 Results

Dean Sigler Batteries, Electric Powerplants, Sky Taxis, Sustainable Aviation Leave a Comment

For the first time in 100 years, the Pulitzer Trophy was awarded to a flight team, and for the first time to a team flying an electric aircraft. Since the Air Race itself was spread over a 50 mile course, spectators could only view the participating aircraft when they departed, passed overhead at the end of one lap of the course, and landed at the end of the race.  This is similar to a longer run for Green Flight Challenge aircraft in 2011.  Spectotors at the Pulitzer Trophy Race would have seen the aircraft a similar number of times, allowing for time to visit the static displays, which included an Opener Blackfly (now called a Pivotal Helix) and a Beta Alia. The event seen in this video was bigger than the small crowd shown, with different groups competing a worldwide series of simulated flights on personal computers.  Middle and high school students, “along with aviation-focused youth organizations,” participated, using X-Plane  …

YASA’s Second Output Record This Year

Dean Sigler Announcements, Electric Powerplants, Sustainable Aviation 2 Comments

Mercedes-Benz, with its YASA (Yokeless and Segmented Armature) motor, has achieved a second world record this year for power density.  Pulling 1,000 horsepower from a 12 kilogram (xx pound) motor seems a bit incredible, but Mercedes has dynomometer tests to prove it. This efffort will be in production cars within a year, according to Mercedes, and the aircraft version, produced by a division called Evolito, will probably follow shortly thereafter. Even while under development at Oxford University, the motor showed great promise, as well as great torque.   This blog included the video below in 2010, with a Lotus 7 copy being flung about handily with two 40 kilowatt (53.6 horsepower) YASAs driving the rear wheels.  At that time, power was limited to 75 kilowatts (100.5 hp.), although designers believed 150 kW (201 hp.) was possible.   That early motor weighed 11 kilograms, or 23.2 pounds, one pound per three limited horsepower, one pound per six horsepower at the design limit.  As …

Dean Sigler Announcements, Electric Powerplants, Sky Taxis, Sustainable Aviation Leave a Comment

Flieger magazine reports, “Piper Deutschland AG has announced a strategic investment in MD Aircraft GmbH . The goal of the collaboration is to advance the development and production of the all-electric regional aircraft MDA1 eViator.” (Note: based on later reporting, the power bays may be incorporated into the lower part of the fuselage.  The blog will attempt to gain verification of this.) Signed on September 19, 2025, the agreement “is intended to mark the start of a new chapter in aviation for Piper – with a focus on innovation and environmental sustainabilit,” according to Flieger. Providing MD the financial stability of Piper’s funding and for Piper the planned design for a twin-motored commuter liner in the size and performance range familiar to established Piper customers, the compact should be beneficial to both companies. The MDA1 Aircraft An “all-electric short-haul aircraft with a range of up to 400 kilometers (248 miles),” The MDA1 should suit the needs of most regional commuter lines internationally. We wrote …

1Comet Debuts at Electrifly-in 2025

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

1Comet, a high-performance, laminar-flow ultralight sailplane, debuted at Electrifly-in 2025 in Bern, Switzerland.  Though looking somewhat like the Ruppert Archeopteryz, there are significant differences. Both 1Comet and Archaeopteryx come in foot-launch and electric-powered versions.  Both fall into the microlight category and are capable of flying in microlift conditions. 1Comet, though, has a broader weight range, from a foot-launched glider with fixed landing gear weighing a total of 165 kilograms (364 pounds) to an electric-powered, retractable gear machine toppin out at 350 kilograms (771 pounds). Archaeopteryx has a removable electric motor behind the pilot, cleverly strapped in with Velcro fasteners.  1Comet has a fixed-position Front Electric Sustainer motor in the nose. The 1Comet web site makes the following claims for the electric-powered version.  “The low weight also makes it the ideal platform for electric flight. With only 30 kg of batteries, you can stay in the air for over 2 hours or climb more than 4000 meters. “The electric glider version …

An Aerial Pulitzer Prize

Win a Pulitzer Without Writing a Word There hasn’t been a Pulitzer Air Race or Prize (Trophy) for 100 years, the last competition taking place in 1925.  The revived Pulitzer Trophy Races will differ considerably from the original events.  Those races were all flown with military aircraft flown by experienced military pilots.  Differing greatly in engines, the earlier contestants all burned fossil fuels: the current competitors will fly on electricity. The Original Pulitzer Air Races The Pulitzer Trophy Races ran only five years, and were also knonw as the National Air Races.  Winners during those five years included: 1920: Corliss Champion Moseley, flying a Verville-Packard 600, 156.54 mph, Nov. 25, Mitchel Field, N.Y. 1921: Bert Acosta, flying a Curtiss, 176.76 mph, Nov. 3, Omaha, Neb. 1922: Russell L. Maughan, flying a Curtiss, 205.80 mph, Oct. 14, Detroit, Mich. 1923: Alford J. Williams, flying a Curtiss R2C1, 243.68 mph, Oct. 6, St. Louis, Mo. 1924: H.H.

Jean-Baptiste’s Disruptive Electrifly-in Win

Dean Sigler Batteries, Electric Aircraft Components, Electric Powerplants, Hybrid Aircraft, Solar Power, Sustainable Aviation Leave a Comment

Jean-Baptiste Loiselet is a disruptive force seemingly immune to conventional thinking.  Funding what he calls a “hybrid” aircraft from his life savings, he has flown his solar sailplane around France, set a world altitude record for electric microlight aircraft, demonstrated its airworthiness at the 2024 Paris Air Show, and recently won his third Electrifly-in award at Bern, Switzerland. The term “disruptive” is one of esteem in high-tech America, but translated into French, the hashtag “rupture” leads to Jean-Baptiste’s LinkedIn site or even to his Des Ailes pour la Planète (Wings for the Planet) website.  The following, a translation of the original French, shows how words can be misapprehended. “⚡️ Rupture or not rupture?  (disruption or not disruption?  Your editor’s interpretation.) “🏆 For the third year in a row, I’m at the top of the podium in Electrifly-In Switzerland for the sole reason that I’m the only one in my category: hybrid. “🌱 Hybrid because the Sol.Ex. is a bit of …
