A 17-year-old Canadian has earned first place at Intel's 2015 International Science and Engineering Fair, which the company claims is the biggest high school science competition in the world. Raymond Wang's system to improve air quality in airplane cabins scooped the US$75,000 top prize ahead of a low-cost HIV testing device and a new containment enclosure for undersea oil wells.
In seeking a compromise between helicopters and fixed-wing aircraft, engineers in recent years have opted for tilt rotors, but NASA has dusted off and improved on a tilt wing aircraft design that takes off and lands like a helicopter and flies like an airplane. Called the Greased Lightning, or GL-10, the unmanned prototype made a successful vertical takeoff and transition to horizontal flight at Fort A.P. Hill, not far from NASA's Langley Research Center in Hampton, Virginia.
