Dryden Flight Research Center -- If an airplane's wings could twist like the wings of a bird, structures for maneuvering could be streamlined and simplified.
The Wright brothers understood this, and incorporated twisting, or wing-warping, into the very first airplane in 1903 to enable the craft to bank for turns.
NASA has returned to the Wright's century-old concept with a new twist: a supersonic jet aircraft at NASA's Dryden Flight Research Center on Edwards Air Force Base, Calif., has been flown with wings that deflect when special leading and trailing edge control surfaces are activated.
The aircraft is the Active Aeroelastic Wing (AAW) F/A-18. The flexible wing provides roll, or bank, comparable to that achieved by a standard stiff-wing F/A-18, while the experimental jet does it with less need for coordinated tail surface inputs to complete a turning maneuver.
Researchers hope this will lead to a revolutionary new rationale for aircraft design.
Stiff wings and heavy control surfaces that use hinges were necessary as 20th century aircraft mechanically coped with the need for faster speeds and larger sizes.
While the AAW airplane still relies on hinges to prove its point, the availability of strong, flexible composite structures and miniaturized computers and motors point the way toward seamless wings that will one day bend to achieve flight control as effortlessly as a bird does.
The results can include greater fuel efficiency in several ways.
Seamless wings create less drag; seamless control surfaces can weigh less than conventional control surfaces; and, a "smart" airplane with seamless wings could one day use computers to sense its most efficient flight configuration, and change its shape to match.
Passengers may one day enjoy smoother flights in bumpy air with computer-operated seamless wings, and the military sees smooth, seamless control surfaces as a way to enhance radar-defeating stealth qualities.
NASA is working with Boeing and the U.S. Air Force on the AAW project.
The quest for a morphing aircraft that changes its shape in flight to meet requirements is ongoing at several NASA aeronautical centers.

A Russian Soyuz-FG booster rocket with the European Space Agency's Mars Express space vehicle is shown on a launchpad in the Baikonur Cosmodrome in the former Soviet republic of Kazakhstan on Friday, May 30 2003. The spacecraft, to be launched on Monday, is set to reach Mars' orbit in half a year and drop its British built Beagle-2 lander.

Lockheed XFV-1 POGO STICK Interceptor
In the Later 1940s, the US Air Force and US Navy became interested in fighters that could take off and land vertically, and therefore do without the long runways of vulnerably land base and expensive aircraft carriers. Turboprop engines, driving contra rotating propeller units seemed to make such types feasible, and in 1951 the navy contracted for a XFO-1 (soon XFV-1) prototype based on the model 081 design. This had a substantial fuselage, mid set wings, and a cruciform tail unit whose four surface each carried a small wheel on its trailing edge. The selected engine was the 7,100-shp YT40-A-14, in which two T-38 turbines each drove a three blade propeller, providing a 1.2/1 thrust/weight ratio. Only the lower rate AT40-A-6 was available for trials, so it was decided to fit the XFV-1 with a temporary fixed landing gear that would allow conventional take off and landing with this engine, Which was not cleared for vertical operation. An unofficial hop was made in December 1953!
during taxiing trials, but the first true flight came only in June 1954. The definitive engine was never made available, and the program was canceled in June 1955.

'Glacier Girl', a World War II P-38 combat plane that was recovered from a glacier in Greenland, takes off from the Middlesboro Airport in Middlesboro, Ky. on Saturday, Oct. 26, 2002. The plane, along with seven others, crash landed in Greenland during a flight from Maine to England in 1942 and was restored over a 10-year period. The plane is now housed at the Middlesboro Airport where the public can view it.

Boeing unveils Bird of Prey stealth aircraft
ST. LOUIS -- Boeing Co. on Friday took the wraps off its top-secret "Bird of Prey" - a futuristic aircraft that's been used the past 10 years to demonstrate stealth technology.
Air Force Secretary James Roche and Chief of Staff Gen. John Jumper were at the unveiling in St. Louis, where the company's fighter planes are built.
The $67 million project, which was fully funded by Boeing, ran in secrecy from 1992 to 1999. Boeing said it decided to reveal the Bird of Prey because the technology capabilities it developed have now become industry standards.
The subsonic single-seat aircraft was developed by the Boeing Phantom Works here and first flew in 1996. Boeing said the aircraft was one of the first to use single-piece composite structures, disposable tooling and 3-D virtual reality design.
