A Seraph in the Earthly Sphere

A Seraph is a six-winged angel in the first sphere of the celestial hierarchy, and while the earthly form in Richard Ike and Ira Munn’s vision may have fewer wings, it is no less inspired. In part, it’s inspired by biomimicry, imitating nature in its forms and even its structure.  The  airfoil-shaped profile of the fuselage “reduce[s] drag and optimize[s] aerodynamic efficiency, the blended-wing-body and lifting body (flying fuselage) maximize lift and produce minimum drag, according to Seraph’s web site. Seraph explains, “Flight with the Seraph will be made possible by two factors, lift generated by airfoil and lift generated by vortex.  The later factor is a return to a principle originally explored by Leonardo Da Vinci.”  Their site further …

Green Flight Challenge sponsored by Google to bring historic firsts to aviation Aviation’s largest ever prize to be awarded at Moffett Field October 3 during exposition hosted by NASA SANTA ROSA, CA (July 29, 2011) – The CAFE Foundation announced today that Google will sponsor the NASA Centennial Challenge flight competition known as the Green Flight Challenge (GFC). CAFE (Comparative Aircraft Flight Efficiency) will conduct the event from September 25 through October 2, 2011 at Charles M. Schulz Sonoma County Airport.  The NASA-funded prize purse of $1.65M makes this the largest ever prize for aviation.  Competing aircraft must demonstrate at least 100 mph and 200 passenger MPG on a 200 mile flight.  The aircraft in the Green Flight Challenge sponsored …

Following rigorous evaluations of all aircraft to ensure they meet all standards for the contest, Dr. Brien Seeley, President of the CAFE Foundation, announced the 13 entrants who will compete in the Green Flight Challenge at Santa Rosa, California between July 11 and 17, 2011.  This exciting event will offer the public a first view of some incredible designs and resourceful competitors.  Since the minimum performance required for consideration includes things such as the ability to fly a 200 mile course at 100 mph or better average speed, the ability to clear a 50-foot barrier on a 2,000 foot runway during both takeoff and landing, and the efficiency to attain at least 200 passenger miles per gallon during the overall flight, all aircraft are obviously the most …
