Chinese researchers claim to have increased the safe-speed threshold for flying-wing platforms by more than 60%, a breakthrough that could be applied to the H-20 stealth bomber.

Boom Supersonic is one step closer to launching the spiritual heir to the Concorde. The US firm's XB-1 prototype reached a transonic speed of Mach 0.95 during Test Flight 11 on January 10, 2025. The ...

Commercial supersonic flight sped closer to returning as the Boom Supersonic XB-1 prototype reached a transonic speed of Mach 0.95 during Test Flight 11 on January 10, 2025, in the skies over the ...

NASA's Sustainable Flight Demonstrator full-scale single-aisle research plane designed to explore net-zero aviation emissions and faster, more economical passenger flight near the speed of sound has ...

Nothing did more to accelerate the development of aviation in the 20th century than World War II. By the time the conflict was over in 1945, the fighters that first tangled five years previously were ...

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 ...

CC0 Usage Conditions ApplyClick for more information. The Bell X-1 was an experimental aircraft designed to gather data on transonic speed: speeds close to the speed of sound. Find out how research ...

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.
