I met Mary Grady at the 2011 Sun ‘n Fun Flyin in Lakeland, Florida. After that, she and I swapped tips and leads for articles. Her work at AVweb and for Belvoir Publications was professional and polished – always. I’m using AVweb’s tribute to her, especially since it shows her many facets. She will be missed. Dean Sigler Mary Grady, one of AVweb’s longest-serving, most dedicated and respected contributing editors, died at her home in Warwick, Rhode Island, on March 12 after a long illness. Mary was one of the founding members of the internet experiment that became AVweb and continued as a key staff writer until her health challenges prompted a leave of absence earlier this year. She worked for AVweb for 20 years and wrote thousands of articles. To the best of anyone’s recollection she never missed a deadline. “Mary had a quiet strength in her professional skills, but also in the way she carried herself,” said Tim Cole, AVweb’s editorial director. “When deadlines loomed or …
Goodyear Aero Wheel Sparks Controversy
Goodyear Creates a Flying Tire Displayed this week at the Geneva Auto Show, Goodyear’s new AERO wheel is not just rolling stock, but a possible aeronautical device that could propel a “flying car” skyward. Not only could it roll along the freeway, it could navigate the vehicle and choose whether to be in highway or aerial mode. These smart tires could have some problems, though, that could negate their aerial potential, according to some critics. Goodyear’s press release extols the possible virtues of the forward-thinking product: “GENEVA, March 5, 2019 /PRNewswire/ — The Goodyear AERO concept is a two-in-one tire designed for the autonomous, flying cars of the future. This concept would work both as a tire for driving on the road and a ‘propeller’ for flying through the sky.” Chris Hensel, Goodyear’s Chief Technology Officer, explains: “For over 120 years Goodyear has obsessively pursued innovations and inventions, partnering with the pioneers driving change and discovery in transport. With mobility companies looking …
Polyplus and SK Team on Glass-Encapsulated Batteries
Polyplus, a Berkeley, California-based battery developer, has teamed with SK, Korea’s” first and largest energy and chemical company,“ to produce and test prototype cells to demonstrate increased volumetric and gravimetric energy density and cycle life relative to existing Li-ion cells.” Just reported, “The PolyPlus lithium-water battery has achieved the highest recorded energy density of 1,300 Watt-hours/kilogram, or an almost 10x improvement* over current lithium-ion batteries. Polyplus projects the energy density for commercial lithium-air batteries to be 1000 watt-hours per kilogram.” As with many recent partnerships, the alliance between Polyplus and SK provides “muscle” for the smaller partner. Polyplus, with 18 bay area employees, will benefit from the far more sizable SK’s financial and managerial expertise. Between the two firms Polyplus’ 135 issued and 40 pending patents should receive proper support. According to Green Car Congress, “SK selected PolyPlus as partner for its global consortium.” The collaboration is focused on PolyPlus’ solid-state lithium anode laminate that has the potential to double the …
Big Events and Numbers for Bye Aerospace
Bye Aerospace has four big current projects, with the Sunflyer 2 at the top of the development and sales curve. Teaming with Siemens, Bye Aerospace is now flying Sunflyer 2 with one of their 57 pound SP70D motors producing a 90 kilowatt peak rating (120 HP), and continuous power up to 70kW (94 HP). Bye anticipates that Sunflyer 2 will be, “the first FAA-certified, practical, all-electric airplane to serve the flight training and general aviation markets.” George Bye, the company’s founder and CEO has been working with Agency for several years on devising rules for electric aircraft certification. The need for 790,000 new pilots in the next few decades will drive the need for training aircraft. An aging fleet with an average age of 48 years for the Pipers and Cessnas on flight school tarmacs requires a newer, more modern series of training planes to replace them. Sunflyer’s impressive sales numbers (a recent order from the Aspen Flying Club for …
Pipistrel, Honeywell Sign MOU
The fun part of writing this blog is receiving news of hopeful aspirations and plans for a thriving future. Taja Boscarol, one of the founders of Pipistrel, shared such news this week. “It is my greatest pleasure and honor to announce that Pipistrel and Honeywell signed an MOU(Memo of Understanding) regarding collaboration on aircraft technologies for urban air mobility.” The Slovenian/American joint venture headlined its press release, “PIPISTREL AND HONEYWELL COLLABORATE ON AIRCRAFT TECHNOLOGIES FOR URBAN AIR MOBILITY,” with the multi-faceted secondary headline, “Pipistrel and Honeywell combine aerospace expertise to address the technical, regulatory and business challenges of the emerging on-demand mobility market.” eVTOL News lists over 140 electric vertical takeoff and landing aircraft on its web site. Early in the 20th century, there were thousands of automobile manufacturers. Such high-end products with their attendant development and manufacturing costs can’t be maintained by all the competitors, especially when market winners survive by growing in efficiency and productivity to make desirable …
Volocopters to Fly Doctors
Helena Treeck of Volocopter alerted your editor of an exciting development for the multicopter manufacturer. ADAC Luftrettung (ADAC Air Rescue) wants to use volocopter’s capabilities to take doctors or other qualified medical personnel to points of need – and rapidly. ADAC’s slogan, “Against time and for life,” sums their mission, and Volocopters seem apt choices to help fulfill it. Rotary-wing aircraft have a well-established reputation for rescues in treacherous locales and circumstances. An outstanding job of flying earlier this year on Mt. Hood, Oregon highlights this. Electric vertical take off and landing craft may be even better at this than fossil-fuel powered ones. They don’t run out of oxygen at altitude – the rescue on Mt. Hood took place near the summit at 11,000 feet, adding to the plentiful hazards. As noted in Helena’s dispatch, “ADAC Luftrettung is the first air rescue organization in the world to test the use of manned multicopters in emergency medical services – both in …
David Ullman Receives Patent on IDEAL Airplane
David Ullman a Professor Emeritus at Oregon State University, has used his expertise in mechanical engineering to design his IDEAL airplane. That stands for Integrated Distributed Electric-Augmented Lift, and like all good projects with good acronyms, almost explains itself. Recently, the U. S Patent office thought the IDEAL is worthy of being patented. It might be helpful to read the full patent, filed with working partner and neighbor Vincent Homer, because the ideal looks simple, but has years of development behind it. The two live in Independence, Oregon, on an airport that includes hangars on every house and taxiways linking them to the main runway. Both their hangars are filled with evidence of their skilled handiwork. Vincent’s houses giant models and evidence of aeronautical investigations. David’s shelters a very large wind tunnel, used to help verify his computations about blowing air over the wing and augmenting the lift while providing thrust. On one wall hangs the twisted wing strut that …
MIT’s Ionic Flyer – Solid State All the Way
This week, a kerfuffle tsunami has swept through the aeronautical press, with the announcement by Steven Barret of the Massachusetts Institute of Technology (MIT) that he has flown an ion-powered airplane that “doesn’t depend on fossil fuels or batteries.”* (A minor point – the airplane does have a battery that gets its output voltage ramped up by a custom power supply.) Five years ago, your editor reported on ionic thrusters, several of which were being tested by Barrett, associate professor of aeronautics and astronautics. These little devices have great promise for moving vehicles in space, where the vacuum presents no aerodynamic drag to overcome. Even a small nudge from a thruster in space will cause a vehicle to accelerate. They work fine for low-speed propulsion of small balloons here on earth, or for lightweight lifters as part of science demonstrations, but have been neglected for heavier-than-air craft until now. Comparing the development level of his ionic airplane to that of …
Volocopters to Hover Over Singapore
Helena Treeck from Volocopter sent the following message this morning: “Bruchsal/Paris/Singapore, October 2018 – Volocopter, the pioneer in urban air mobility, announced today during Autonomy – the Summit of Urban Mobility in Paris, that they will perform a next set of inner urban flight tests in Singapore. The series of test that are scheduled to take place in the second half of 2019 are supported by the Ministry of Transport (MOT), Civil Aviation Authority of Singapore (CAAS), and Economic Development Board (EDB).” Already undergoing testing in Germany and Dubai, Volocopter’s 2X appears to be the company’s flagship for continuing development. The following video (in French) intercuts a representative explaining the benefits of the Volocopter with images of its public flight testing in Dubai. There are apparently less well-publicized tests in the nearby desert and ongoing development in Germany. Ms. Treeck’s press released provides more goals. “These flight tests are designed to validate and verify the ability of Volocopter’s eVTOL vehicles …
“StratoAirNet” Prototype Completes 1st Flight
George E. Bye. CEO and founder of Bye Aerospace, is on a roll these days, selling a large number of SunFlyer 2 training aircraft, delivering Silent Falcon solar electric unmanned aerial vehicles (UAVs), partnering in the TriFan 600 project with XTI Aircraft, and overseeing the first flight of the StratoAirNet prototype. A letter from Diane Simard, Senior Vice President of Bye Aerospace, Inc., reports “the successful completion of the first flight of the solar electric technology demonstrator prototype for its “StratoAirNet” and “Solesa” families of medium-altitude aircraft systems.” Flying from the Northern Colorado Regional Airport, north of Loveland, the sailplane-based optionally-piloted vehicle has made additional flights since its maiden outing. Bye expressed happiness at the event and gave thanks to those who made it possible. “It was a great day for solar-electric aviation. My thanks to our entire team for their persistence and extra efforts to achieve this milestone. I would also like to thank the professionals at Northern Colorado …
