The Icarus Cup — A Human Powered Aircraft Competition

January 23, 2014 7:09 am

After just two years, the Icarus Cup has become the world’s most elaborate human-powered aircraft competition. The contest, which is held north of London in the English countryside, pits the innovative pedal-powered aircrafts of engineers, pilots and flying enthusiasts against each other in a series of rigorous aerial competitions that test the limits of speed, endurance and maneuverability. Last summer, Popular Mechanics sent me to cover one of the competing teams led by David Barford, a blue-collar machinist who spent eight years and £8000 ($12,500) building an 88-pound aircraft called the Betterfly in his suburban home. Barford’s design took home the 2013 cup.

Next time you’re at the newsstand pick up a copy of the February issue of Popular Mechanics. Below are some images from the story, but the essay written by Jeff Wise is a must read as well.

Peter & Jo White have volunteered as marshals for both years at the Icarus Cup. They participate out of pure interest and their love for aviation. Marshals keep note of time, windspeed and make sure everyone stays safe during the festivities.

Human powered aircraft gather at the end of the 2013 Icarus Cup. Of the four planes that competed, only two flew more than 1 minute. Organizers hope to turn this obscure hobby into a sport.

    I really enjoyed the picture show you have here. Is everyone in your organization an engineer or craftsman up for a challenge? I myself am trying to figure out how you guys design and test parts from the prop to the wings, to avoiding the use of a gearbox to power the prop. Plus I never had any luck with epoxy and cloth on the blue foam. It almost always bubbled or came off when the surface got hot or you bumped it hard. Vacu-bagging didn’t seem to help, but I suspected my pump was maybe to weak. I’d love to correspond with you in email if you have the time.
