Lange Aviation explained the large glider-like machine on display at the 2018 Aero Expo this way: “During this year’s AERO in Friedrichshafen, a mock-up of the Antares E2 was displayed publicly for the first time by our sister company, Lange Research Aircraft GmbH. The Antares E2 is an aircraft with an extreme endurance and very high reliability, which has been designed primarily to address maritime monitoring tasks such as fishery control. In order to fulfill the design goals, a novel propulsive system using six fuel-cell systems and six over-wing propulsors has been developed.  A Large, Heavy Machine Beyond Glider Status Weighing in at a hefty 1,650 kilograms (3,630 pounds), the Lange E2 carries that weight on a 23 meter (75.45 …

Alpha Electro Achieves FAA Certification

Dean Sigler Announcements, Electric Powerplants, Sustainable Aviation 0 Comments

A Big Day in Fresno Following certification for Pipistrel’s Alpha Electro trainer in Australia, China, and Canada, the FAA presented this highly-valued acknowledgment that the aircraft meets current airworthiness standards.  After waiting for the agency to remove the restrictive word “reciprocating” from its Light Sport Aircraft regulations, electric aircraft designers have permission to field aircraft with truly modern powerplants. With FAA inspectors painstakingly perusing every part of the Electros, a formal presentation followed, enabling the Sustainable Aviation Project to move forward with plans to bring low-cost pilot training to the Fresno, California area. Officials from the four cities in which Alpha Electros will be hangared were on hand to lend encouragement during the public flight displays of the aircraft. For …

A U. S. Debut in Chicago Mary Grady, writing in AVweb, reports that “Siemens brought its prototype electric aircraft to the U.S. this week for the first time, showcasing the airplane at the company’s Innovation Day in Chicago. ‘Electric propulsion is one of the transformative technologies that will help the industry meet the goals of reduced fuel, emissions and noise,’ said Teri Hamlin, vice president of electric propulsion for Siemens. ‘By accomplishing testing on our systems on select flying testbeds in the lower power classes, we are gaining valuable experience and knowledge that accelerates and validates our other developments in hybrid-electric propulsion systems in the high power classes.’“ Testing in Waco Further testing of the technology will take place in …

Sunflyer Takes to the Air

Dean Sigler Announcements, Batteries, Electric Powerplants, Sustainable Aviation 0 Comments

Following assorted powerplant and taxi texts, the prototype Sun Flyer 2 prototype took to the air over Centennial Airport (KAPA) south of Denver, Colorado.  Further tests will expand speed, altitude, and endurance capabilities, according to Bye Aerospace. George Bye, Founder and CEO of Bye Aerospace, enthused, “We are excited about the future and the potential the Sun Flyer family of aircraft has to revolutionize general aviation, providing improved affordability and accessibility.  Lower operating costs are key to solving the student pilot drop-out rate, which is curtailing the successful attainment of badly needed airline pilots. The Sun Flyer 2’s $3 hourly operating costs are 10 times lower than traditional piston-engine flight trainers, with no carbon emissions and significantly reduced noise.” Such …

Pipistrel Alpha Electros Come to California

Dean Sigler Announcements, Electric Powerplants, Sustainable Aviation 0 Comments

News from Joseph Oldham, founder of the Sustainable Aviation Project, and Michael Coates, United States master distributor for Pipistrel Aircraft, heralds the largest delivery of electric training aircraft to date.  Four Pipistrel Alpha Electro Trainers showed up at Fresno, California’s Chandler Airport, all part of the Sustainable Aviation Project.  Described as “a public-private collaboration to reduce the cost of flight training through the use of all-electric general aviation airplanes,” the Project might become a role model for future electric flight training. On March 19, two 18-wheel trucks delivered two 40-foot shipping containers.  Each container carried two Alpha Electros, two chargers, and a pair of replacement battery packs for each airplane.  It took a mere two hours for a volunteer crew …

Join us to …

Zee?  Kitty Hawk? Cora?

Dean Sigler Announcements, Sky Taxis, Sustainable Aviation 0 Comments

Different Names, Different Configurations Zee, One of two aircraft companies funded by Google founder and CEO Larry Page, has been a highly mysterious business.  Its web pages mostly gave discrete job descriptions for those willing to sign up for a mostly undefined mission.  Occasional glimpses of patent drawings, spy shots of a multi-rotor craft in Google’s Mountain View, California parking lot came into view, and later, in-flight shots of other, different looking craft came from Hollister, California. Kitty Hawk, the other company funded by Larry Page, seems to have subsumed Zee and produced a 12-rotor, single-propeller aerial taxi about the size of a Cessna 150, but capable of vertical takeoffs and landings and seamless transitions to forward flight.  A white …

Schleicher’s Sustainable Flight for Two

Dean Sigler Announcements, Batteries, Electric Powerplants, Sustainable Aviation 0 Comments

Alexander Schleicher Segelflugzeugbau (sailplane maker) has been crafting high-performance soaring craft since its inception in 1927.  Their latest creation, a two-seat, 20-meter (65.6 feet) span motorsegler, the ASG32 El, includes a 25 kilowatt synchronous motor driving a Schleicher-designed 1.55 meter (5 feet) retractable propeller.   The motor is a “home help” device, a sustainer motor to keep the ASG 32 El aloft once it is launched by a winch or by being pulled by a towplane.  The motor does not allow for self-launching.  Its low power, coupled with the airplane’s clean design, does enable a 1.3 meter-per-second (255 feet per minute) rate of climb.  The aircraft’s battery is sufficient for 20 minutes of all-out power or 100 kilometers (62 miles) …
