It's the albatross wing that comes the closest to that of the X-66A, which is called a transonic truss-braced wing (TTBW). Its purpose is to fly in the transonic region. That is, at speeds between ...

“Transonic” tunnels (close to the speed of sound) are much more difficult. At this critical speed, very important in the study of aerodynamics, the tunnel tends to “choke.” Shock waves ...

Aviation engineers are on a never-ending mission to make the most streamlined, airworthy design possible. But one common ...

This design, known as transonic truss-braced wing (TTBW), could in theory allow the plane to generate more lift, thus reducing the amount of fuel it needs for certain portions of the flight.

The Phantom 3500 is the latest transonic aircraft in development, offering an unconventional take on modern private air travel. It swaps traditional windows for ultra-realistic high-definition ...

The aircraft—being developed with a transonic truss-braced wing—is on “pause for later consideration” after Boeing proposed to focus on a ground-based testbed, which will instead ...

Aerodynamic and structural data on the X-66 were obtained from wind tunnel tests of a 5.3%-scale model in the Transonic Unitary Plan Facility at NASA’s Ames Research Center in California.
