NASA and Boeing jointly develop a winged wing aircraft

Specialists controlled by Boeing and NASA project Spanwise Adaptive Wing have developed a special alloy, with which you can make lightweight folding wings.

The idea of ​​creating a flexible wing is not new, but all the developers who tried to do something like that before inevitably encountered difficulties - the hydraulic mechanisms used to bend the wings were cumbersome, heavy and therefore the aircraft equipped with them had more flaws than advantages.
The new drives developed by NASA together with Boeing and several research centers are lighter than the old prototypes by 80%. They are made of alloys with a "shape memory", and even they can be used even in supersonic aircraft.

Recently, NASA conducted tests controlled remotely prototype, whose wings can bend up and down from 0 to 70 degrees. The prototype made three flights with wings in the "zero" position, with a 70 degree curve upward and down the same number.

Engineers came to the conclusion that the use of the new alloy is justified, because the prototype produced excellent performance throughout the three flights. The material from which the wings are made, also showed itself very well, remaining stable throughout all three flights, which could not be said about other materials that tried to apply for similar purposes earlier.
