Fixed-wing flight

The Challenge: Fixed-wing flight requires an efficient airfoil, such as a wing that’s curved on top and flat on the bottom. As the airfoil moves forward, air streams faster over its top than underneath it, creating a difference in pressure. When the pressure below the craft overcomes the pressure above it, there is a net upward force. Most planes use engines to get enough forward motion, but people can’t propel a vehicle nearly as fast. The Solution: In general, the longer the wings, the more lift. In the early ’60s, Southampton University undergraduates built a 130-pound craft with an 80-foot-wingspan and a bicycle-style transmission connected to a propeller. It flew a third of a mile but had significant steering problems. In 1977, engineer Paul MacCready designed the Gossamer Condor, a 70-pound aluminum and plastic craft with a canard—an airfoil on a boom in front of the fuselage. It was more maneuverable than its predecessors and flew in a figure eight around markers a half-mile apart, winning the Royal Aeronautical Society’s prize for the first controlled and sustained human-powered flight. There’s still room for improvement. For example, engineers have refurbished the ’90s Airglow with bent wingtips and curvier wings—improvements that stabilize it during turns.
