The blade tip speed limit of a propeller plane's propeller can determine the plane's top speed for reasons relating to design ...

Transonic buffet is an aerodynamic instability encountered in the transonic flight regime. Manifesting as self-sustained oscillations of shock waves on the wing surfaces, this phenomenon leads to ...

A Gripen D fighter jet pierces through the clouds above southern Sweden and is soon cruising at nearly the speed of sound.

Transonic shock analysis occupies a central role in understanding fluid dynamics where flows transition between supersonic and subsonic regimes within Euler systems. In these scenarios, a shock ...

Meet the X-66A, NASA's Sustainable Flight Demonstrator full-scale single-aisle research plane, featuring transonic truss-braced wings and designed to explore net-zero aviation emissions and more ...

Supersonic wind tunnels are rather simple (though very expensive) to build. When their air moves well above the speed of sound, it passes through the experimental chamber in a smooth, even stream.

Boeing is developing the Transonic Truss-Braced Wing configuration through the Sustainable Flight National Partnership, a NASA initiative to make aviation more environmentally friendly.

The images are both stunning and a visual physics lesson on shockwaves created by a jet moving through thick air at high speed.

Boeing is pausing development of the X-66 transonic truss-braced wing aircraft with NASA and reallocating resources to get the 737-7, 737-10 and 777X certified.

Boeing is pumping the brakes on its experimental X-66 flight demonstrator. The aircraft—being developed with a transonic truss-braced wing—is on “pause for later consideration” after ...
