What aerial technique was developed by US engineer Francis Rogallo
in the 1940s?
The triangular wings are known to aeronautical engineers as Rogallo wings, with their origins going back to the late 1940s.
That was when Francis Rogallo, an engineer with the American National Advisory Committee on Aeronautics, NACA, first devised an ultra-light wing with the first models cut up from a kitchen curtain.
Rogallo himself retired from Nasa in 1970, bringing the story of flight full circle to settle in Kitty Hawk, North Carolina, where the Wright brothers had made their first powered flights back in 1903.
What aerial technique was perfected by US engineer Francis Rogallo
in the 1970s?
Among the aircraft he flew was a Rogallo
paraglider, which was used to study the possibility of using an inflatable wing for landing spacecraft, and wingless ``lifting-body'' aircraft.
Of special interest is the Rogallo
Wing proposed for Gemini space capsule recovery in the early 1960s.
The modern ultralight movement was born when NASA invented the Rogallo
wing in the mid-1960s.
Peterson's career at what is now NASA's Dryden Flight Research Center at Edwards included flight testing the Rogallo
paraglider aircraft, which was used to study the feasibility of using an inflatable wing for landing spacecraft, and ``lifting-body'' aircraft - wingless aircraft that contributed to the space shuttle program and to today's research for a new manned spacecraft.
