Designing Airplanes That Shape Shift to Fly Electrically

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 …

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 90 feet (home plate to first base), able to climb at an angle that would clear the 150-foot Matterhorn at Disneyland by the time it reaches the end of a 420-foot runway, and being nearly inaudible as it crosses the …
