Some may already be familiar with the sonic boom that accompanies a break to the sound barrier, but when and why would ...

Strong jet streams across the Atlantic are seeing passenger airplanes knock more than an hour off their flight times, as they hit speeds of 761 mph – the speed of sound. However, they’re not ...

India has tested a game-changing hypersonic missile that could join the ranks of elite nations. What makes it a strategic ...

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

High temperatures aren’t the only challenge to high-speed travel. In some cases, the boundary layer doesn’t transition evenly, which means that one half of the vehicle could be impacted by the smooth, ...

And on Earth, the speed of sound varies depending on the temperature of the air an aircraft is traveling through. Breaking the so-called sound barrier in 1947 made Chuck Yeager famous.

Hypersonic weapons, which fly at speeds in excess of Mach 5, or five times the speed of sound, could pose crucial challenges to missile-defense systems because of their speed and maneuverability.

The team calculated sound speed and attenuation at different points of time in the planet's year (which is about 687 Earth days) and in various spots across the Martian landscape, ...
