A Lighter, Zippier Tire for Electric Airplanes?

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 0 Comments

Tires are not usually the first thing that comes to mind when thinking of airplane design.  On most aircraft, the landing gear is an awkward necessity, something to help one get airborne and settle on after committing aviation.  Our future electric aircraft might have power-driven wheels to shorten takeoff and landing distances, making them less inconvenient and more beneficial. Conventional rubber tires and wheels are heavy, though, and reducing their avoirdupois would enable better performance from a lighter airplane, or allow more batteries for longer range or better performance.  Dr. Brien Seeley, founder and President of the CAFE Foundation, wants to visit the best of all possible tire worlds by exploring the potential of polyurethane tires, reducing the need for …

The Man Who Made This Blog Possible

Your editor received this sad announcement yesterday from Andy Kecskes, editor of the Sailplane Builder newsletter, forwarded from Murry Rozansky, President of the Experimental Soaring Association. “Bruce Carmichael passed peacefully with his family by his side on Tues. I am glad that our and the other soaring organizations honored his contributions before this sad event. Bruce was 91+years old, an accomplishment in itself.  There will be a celebration of Bruce’s life on Sat. Aug. 15th at 10:30 am at Palisade’s Methodist Church, 27002 Camino de Estrella, Capistrano Beach, CA.  Reception to follow services.”  Please RSVP to; georgianatives@yahoo.com.” Bruce was a pioneer in low-Reynolds number aerodynamics, and had been influential in the design of many record-breaking and visionary aircraft.  He is listed …

13th Annual Personal Aircraft Design Academy Meeting Honors Popov

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

At the Experimental Aircraft Association’s AirVenture, a week of grand aviation events comes to a close with the annual Personal Aircraft Design Academy meeting.  Each year, an individual or group who has contributed significantly to the progress of personal aviation receives a trophy in recognition of that contribution.  Your editor could not be there this year, but CAFE President Brien Seeley officiated and shares this report. “The Personal Aircraft Design Academy (PADA) convened its 13th annual meeting on July 24 at 7:30 p. m. in the EAA Vette Theatre. After nominations and voting by members of the PADA Board, the group presented the perpetual PADA Trophy to Boris Popov for his career-long achievements in bringing forth ballistic recovery systems for aircraft. Boris …

Good News and a Bright Future from EAS IX

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 1 Comment

Sitting next to your editor for the first day of CAFE’s ninth annual Electric Aircraft Symposium, Paul Bertorelli from AVweb, took copious notes, made sound recordings, and during coffee and lunch breaks and in after-hours sessions, interviewed the accomplished faculty at the Symposium.  His thorough and far-reaching reports appear in his last several days’ postings to AVweb.  Having stressed mightily while attempting to take understandable notes from each speaker’s talk, your editor can only be impressed by Paul’s super reportorial abilities, and his communicating the scope and importance of what took place at EAS IX. From your editor’s perspective, several significant things took place this year.  Senior leadership from Airbus and Siemens presented talks affirming their companies’ commitment to making …

Adam and Jamie are Paying Attention

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Dr. Seeley alerted your editor this morning that Adam Savage and Jamie Hyneman’s web site, Tested.com, featured an entry on electric aircraft, “Fuel-Free Flight: the State of Electric Airplanes,” by Terry Dunn.  Dunn does a good job of covering history and advantages of electric aircraft – complete with a quote from Dr. Seeley about the good neighbor aspect of quiet electric airplanes. He also discusses the barriers to electric aircraft development beyond current motor gliders and light aircraft – mainly the question of obtaining batteries that have much better energy densities than those currently available. “The batteries currently available are adequate to provide suitable range for some flyers. As the pool of available batteries improves, so will the range of …

PADA Lectures Highlight Innovation

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

The 2014 Personal Aircraft Design Academy (PADA) dinner and awards ceremony, the latter held in the Vette Theater at the Experimental Aircraft Association’s Museum, highlighted design innovation and the possible commercial exploitation of new technology.  Dr. Brien Seeley, Founder and President of the CAFE Foundation, hosted the evening and introduced your CAFE blog editor, who gave an overview of innovations in aircraft, avionics and powerplants he’d encountered on his daily hikes around Wittman Field. Dr. Seeley had the honor of presenting this year’s PADA trophy to John O’Leary, Vice President and General Manager of Airbus Americas Engineering (AAE), for the parent company’s development of the E-Fan, a twin-motored personal airplane that has been a highlight of the Paris and Farnborough …

EAS VIII: Bruno Mombrinie and Dr. Brien Seeley – Economies and Practical Considerations for Sky Taxis

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 0 Comments

Bruno Mombrinie, a director for the CAFE Foundation, and Dr. Brien Seeley, founder and President of the organization, gave a one-two presentation on pocket airports and Sky Taxis that examined the practical and operational facets of such a program, first described in detail in a joint NASA/CAFE Foundation document.  According to Bruno’s CAFE biography, “As a freshman, he helped build MIT’s Chrysalis human powered airplane. Later that summer he got to fly the plane several times. ‘The feeling of being so, so high (39ft)…to fly under my own power was beyond…I just wanted to burst…actually I was so out of breath from the effort, I could hardly mouth ‘yippee!’”  (The Chrysalis, and other MIT designs led to Daedalus, the HPA that flew from Crete …

EAS VIII: Making Small Airplanes Ride Smoothly

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Dr. C. P. (Case) van Dam of the University of California at Davis provided some counter-intuitive pointers on making small airplanes ride more smoothly to participants at the eighth annual Electric Aircraft Symposium in late April.  His solutions for ride quality enhancement in small airplanes are an essential ingredient in making electric Sky Taxis a plausible reality.  Because at least initially many electric aircraft are constrained to long wing spans and light wing loadings, they are subject to “perturbations of significant magnitude to be unacceptable.”  These disruptions of the intended altitude and direction of the aircraft can be more upsetting to passengers than to the aircraft itself, but van Dam had several suggestions to alleviate the vertical and lateral accelerations …
