Hypersonic flight is flight through the atmosphere below altitudes of about 90 km (56 mi) at speeds greater than Mach 5, a speed where dissociation of air begins to become significant and high heat loads exist. Speeds over Mach 25 have been achieved below the thermosphere as of 2020. [citation needed]
While reusable hypersonic flight was first proven in the 1960s, both Russia and China have advanced hypersonic flight to the next level by developing weapons that not only fly fast but also at low ...
Hypersonic missiles, like the Kinzhal rockets deployed by the Russian Air Force, are thought to represent the next generation of arms because they can move at such exceptionally high velocities.
A young team of Chinese scientists say a hypersonic missile could fly further and longer by bouncing bounce off the Earth's atmosphere. Chinese scientists say they've found a way to make ...
Comparison of Ballistic Missile and Hypersonic Glide Vehicle (C-HGB) Flight Trajectories for the LRHW Program Scramjet-powered hypersonic cruise missile. A hypersonic weapon is a weapon capable of travelling at hypersonic speed, defined as above Mach 5, or above 5 times the speed of sound.
This latest flight was a culmination of a three-year, three-flight program to successfully demonstrate the feasibility of using ground-launched sounding rockets as a low-cost approach to hypersonic flight testing, and represents the world's first flight test of an air-breathing, scramjet-powered vehicle using hydrocarbon fuel.
The U.S. has so far spent roughly $10 billion to develop hypersonic weaponry over the past three years, Russia and China are aggressively testing them, and another nine countries are pursuing them ...
Simulation of hypersonic speed (Mach 5) While the definition of hypersonic flow can be quite vague and is generally debatable (especially due to the absence of discontinuity between supersonic and hypersonic flows), a hypersonic flow may be characterized by certain physical phenomena that can no longer be analytically discounted as in supersonic flow.
