A Lighter, Zippier Tire for Electric Airplanes?

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 …

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

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 …
