The dangers of the sound barrier were well-known: when airplanes approached the speed of sound, in the so-called "transonic" zone — pilots found they became hard to fly. Sometimes control could ...

The US firm's XB-1 prototype reached a transonic speed of Mach 0.95 during Test Flight 11 on January 10, 2025. The test took place over the Mojave Desert in California. Boom Supersonic was founded ...

Up to now the best results have been obtained with PSP in transonic speed ranges because of the high absolute pressure differences. The main challenge to get acceptable PSP results on one hand is the ...

The transonic cascade wind tunnel (TGK) is installed at the Institute of Propulsion ... is also unique due to its extremely stable test conditions, especially at the speed of sound. Among other things ...

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 ...

In 2019, the concept was redesigned to cruise at the edge of transonic speed, around Mach 0.8 (593 mph, 955 km/h), and whether because of the added speed or simply from a better understanding of ...

Putting the aircraft under this strain at transonic speed, just below the speed of sound, demonstrates the robust quality of its airframe and proves it will remain controllable at higher speeds.
