TAG – You’re Down!

Dean Sigler Electric Aircraft Components, Electric Powerplants, Sustainable Aviation Leave a Comment

Nailing the landing is a big test for gymnasts, birds, and in the near future – for electric commuter aircraft.  Landing in an impossibly short distance seemed like a mission only for helicopters until recently.  Fixed-wing machines seem at a disadvantage here, rotary-wing craft having the edge in being able to set down almost anywhere, and on the proverbial dime.  Brien Seeley’s TAG may make it possible for fixed-wing craft to emulate birds. Fixed-wing craft have the advantage in point-to-point speed – a big selling point for commuter craft.  High cruising speeds and short ground runs seem mutually exclusive, although new designs and inspired amateurs are showing the way to combining the best of both worlds. First, it’s apparent from the demonstrations of the Valdez STOL (Short Takeoff and Landing) aircraft at Oshkosh’s Airventure that simple, light aircraft can come close to single-plane-length ground rolls coming and going.  It’s a skill bush pilots have worked on for years, and with …

Designing Airplanes That Shape Shift to Fly Electrically

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

Dr. Brien Seeley has a dream, often repeated in this blog, of bringing pocket airparks into our neighborhoods.  But the ideal of commuting by small two-seat aircraft and alleviating the crushing gridlock on our highways can only be realized with aircraft that are quiet, able to land and take off within a football field (much like ultralights), and yet cruise at up to 200 miles per hour (much like high-performance lightplanes).  This amalgamation of Quicksilver and Lancair might seem unlikely, but Dan Raymer showed attendees at this year’s Electric Aircraft Symposium a possible solution to the dichotomy. Raymer, head of Conceptual Research Corporation and author of Aircraft Design: A Conceptual Approach, and Dan Raymer’s Simplified Aircraft Design for Homebuilders, is an internationally-recognized expert in RDS, or robust design strategies.  RDS is defined as a systematic approach to finding optimum values of design factors which result in economical designs with low variability.  As a recognized expert in this area, Raymer brought his …

Aviation Week Recognizes CAFE Foundation’s Efforts

As noted in this blog. Dr. Brien Seeley, President of the CAFE Foundation, has been actively promoting the idea of a short to intermediate range Sky Taxi, a two-seat aerial vehicle that would carry its passengers safely from 420-foot runway “pocket airports” to other such runways at other urban and suburban settings, or even pockets situated within major airports.  The safety and utility promised by these electrically-powered aircraft would provide convenient, inexpensive trips for commuters who would enjoy TSA-free travel up to 500 miles at point-to-point speeds exceeding even private LearJets. Aviation Week recently noted efforts by John Langford, CEO of UAV specialist Aurora Flight Sciences, to achieve part of Dr. Seeley’s far-reaching goals with today’s technology.  As Graham Warwick reports in the magazine, “Five years after DayJet’s on-demand air service using very light jets ceased operations, the dream of air taxis remains alive. But industry is looking at unmanned aircraft technology as a way to reduce or eliminate the …

5th Annual CAFE Electric Aircraft Symposium Launches New Age of Flight

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 1 Comment

Dr. Brien Seeley, founder and President of the CAFE Foundation, shares this important news. SANTA ROSA, CA.—On April 29-30, 2011, an outstanding faculty from NASA, industry and academia will present the technologies necessary to inaugurate the Age of Electric Flight.  The 5th Annual CAFE Electric Aircraft Symposium (EAS V) will reveal how safe, emission-free, 2-4 seat electric aircraft could soon make a doorstep-to-doorstep round trip from San Francisco to Los Angeles on a single battery charge at nearly twice the overall trip speed of airline travel.  The latest breakthroughs in energy storage, motors, quiet propulsion, powered lift, electronic pilot assistance, autonomous flight and aerodynamics will be presented along with proposals for how they can transform transportation. EAS V will again network its faculty with the attendees, including venture capitalists, leaders of the aircraft industry, government researchers and aviation enthusiasts in the highly successful evening Theme Dinners in the Grand Ballroom of the Flamingo Resort and Spa in Santa Rosa, California.  As …
