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 to Sicily on April 23, 1988 – 72.44 miles in less than four hours.) This experience with extreme pedal power probably helped inspire his work on the Negative Mass two-piece crankset, reputedly the world’s lightest and stiffest bicycle crankset.  His …

52 Years of Human-Powered Flight

This year’s Icarus Cup, a human-powered flight competition, was held at Sywell Aerodrome, about 75 miles and nearly two hours north of London.  The Royal Aeronautical Society hosted the first Icarus Cup last year, and explains its origins and purpose.  “In 2011, we commemorated the 50th anniversary of the first flight by a human powered aircraft. The origins of human powered flight begin in 1959, when the Royal Aeronautical Society Human Powered Aircraft Specialist group was formed. Two years later, November 1961 marked the first human powered flight by Derek Piggott. Since then, human powered aircraft enthusiasts have been competing for the Society’s Kremer Prizes . “One of the Human Powered Aircraft Group’s objectives is to promote human powered flight as a sport and encourage wider participation, perhaps one day appearing at the Olympics. The idea of the Icarus Cup was conceived as a way to inspire more people to design, build and fly aircraft themselves and provide an environment for them to …

The Icarus Cup – As Green As It Gets

Dreams of human-powered flight go back at least to the myth of Daedelus and Icarus attempting to flee their Cretan prison by fashioning wings from feathers and wax.  Your editor doesn’t know why we continue to name festivals of flight for Icarus, since he was the young, foolish soul who flew too close to the sun and melted his wings.  His older, wiser father heeded his own advice and made the trip safely because he was not so bold.  Maybe we use Icarus’ name out of respect for his sacrifice. In the spirit of the two mythical aviators and Leonardo daVinci, Italian designer Enea Bossi and builder Vittorio Bonomi oversaw several bungee-launched flights in 1936 with their spruce, balsa wood and light fabric covered Pedaliante.  A 17-meter (55 feet) wingspan, twin propeller airplane, the 220-pound vehicle made as many as 40 flights, but the records are apparently hazy on their duration and distance under human power. World War II intervened …
