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.
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]
A director at the Center for Strategic and International Studies said that Oreshnik's warheads, even inert, can cause "a lot of damage" because of the kinetic energy created by their hypersonic speed. [11] Satellite images later revealed minimal damage to the roofs of Pivdenmash buildings and to the nearby private sector. [12] [13] [14]
Hypersonic missiles typically launch a warhead that travels at more than five times the speed of sound or about 6,200 km per hour (3,850 mph), often manoeuvring at rel ...
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.
Strictly speaking, hypersonic weapons are those that equal or exceed speeds equivalent to five times the speed of sound. But in modern usage, the term usually refers to two specific kinds of weapon.
A hypersonic weapon is a weapon capable of travelling at hypersonic speed, defined as between 5 and 25 times the speed of sound. [ 1 ] Below such speeds, weapons would be characterized as subsonic or supersonic , while above such speeds, the molecules of the atmosphere disassociate into a plasma which makes control and communication difficult.
The term “hypersonic” is often used to refer to what are called hypersonic glide vehicles and hypersonic cruise missiles, highly advanced weapons that can maneuver at hypersonic speed inside ...
