NASA is investigating “the integration of nanoelectrofuel (NEF) flow batteries with rim-driven electric motors to produce a safe, clean and quiet propulsion system for aircraft,” according to Aviation Week. That is the promise of an early-stage rechargeable liquid battery technology under investigation by NASA. The agency is researching the integration of NEF flow batteries with rim-driven electric motors to produce a safe, clean and quiet propulsion system for aircraft.  The rim-driven motors are used on boats as thrusters, and may have applications on small unmanned aircraft, although researchers have seen disappointing results so far. Tying these motors to more promising research into” non-explosive energy storage technology” is part of NASA Armstrong Flight Research Center’s Aqueous Quick-Charging Battery Integration for Flight …

A Twin-Motored Ultralight Flying Wing – It’s the New Millennium

Richard Glassock, an Australian now living and working in Hungary, sent the links to YouTube videos of a Millennium hang glider, neatly electrified and flown at this year’s Santa Cruz Salt Flats Race.  Richard has been a speaker at the Electric Aircraft Symposium with a talk on his efforts with small hybrid electric power systems for large-scale models and small aircraft. Steve Morris, co-designer of the Millennium along with Ilan Kroo, Brian Porter, Brian Robbins, and Erik Beckman helped develop this rigid-wing hang glider to offer a lighter, more portable version of Swift.  Steve reported on his electric-powered Swift at the 2010 Electric Aircraft Symposium. Ilan Kroo reflected on the idea of practical, powered ultralight sailplanes in his American Institute …

Seattle’s Museum of Flight on Boeing Field will host a one-day event, Powering Imagination, an electric flight symposium organized by Erik Lindbergh, grandson of Charles and Anne Morrow Lindbergh. Presentations will be held in the William M. Allen Theater at the Museum, starting at 10:00 a.m. on Saturday, February 28 and ending at 5:00 p.m.   Admission is free, but RSVP to cwilcox@museumofflight.org to guarantee a seat. Topics include an update on the NASA LEAPTech aircraft being designed and built by Joby Aviation and powered by Joby motors.  This 20-motor (!) aircraft will achieve a high coefficient of lift from the motors that distribute thrust over the entire span. Eric Lindbergh will talk about the Quiet Flight Initiative, a multi-pronged approach to …

Dr. Seeley Speaks at AIAA Conference, NASA Dryden

Dr. Brien Seeley, Founder and President of the CAFE Foundation, has been giving a series of talks at the Experimental Aircraft Association’s AirVenture 2013, before a gathering of technical experts at NASA’s Dryden Flight Test Center, Edwards Air Force and at the American Institute of Aeronautics and Astronautics (AIAA) International Powered Lift Conference in Los Angeles. The International Powered Lift Conference focuses on the latest developments in Vertical or Short Takeoff and Landing (V/STOL) aircraft research, concepts, and programs, something of great interest to CAFE in its development of airplanes capable of using pocket airports. Pocket Airports will require a special type of airplane – electric, according to Dr. Seeley, and capable of taking off with a ground roll of …
