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.
The first manufactured object to achieve hypersonic flight was the two-stage Bumper rocket, consisting of a WAC Corporal second stage set on top of a V-2 first stage. In February 1949, at White Sands, the rocket reached a speed of 8,290 km/h (5,150 mph), or about Mach 6.7. [2]
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. [1] Below Mach 1, weapons would be characterized as subsonic, and above Mach 1, as supersonic. Typical Low Earth Orbit atmospheric re-entry speed is Mach 25. [2]
Capable of flying in excess of Mach 3.2 (around 2,200 mph), the SR-71 has been the pinnacle of aviation speed for nearly half a century, but the Atlanta-based aviation company Hermeus thinks it ...
It is the first hypersonic weapon compatible with a fifth-generation fighter. The missile was unveiled in April 2024 at the Navy League’s Sea Air Space exposition in Maryland, with Lockheed Martin pitching it to both the U.S. Navy and Air Force. It has also been considered for deployment on submarines and surface warships. [1]
North Korea first tested a hypersonic missile on September 28, 2021, followed by two further tests in early January 2022. But Sunday’s test showed a jump in North Korean technology, according to ...
An ICBM is a ballistic missile that is generally considered to have a range of over 3,400 miles. It is fired into space from silos or road-mobile transporter erector launchers.
The X-15 set speed and altitude records in the 1960s, crossing the edge of outer space and returning with valuable data used in aircraft and spacecraft design. The X-15's highest speed, 4,520 miles per hour (7,274 km/h; 2,021 m/s), [ 1 ] was achieved on 3 October 1967, [ 2 ] when William J. Knight flew at Mach 6.7 at an altitude of 102,100 feet ...
