Simulation of hypersonic speed (Mach 5) While the definition of hypersonic flow can be quite vague and is generally debatable (especially because of 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.
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]
The subsonic speed range is that range of speeds within which, all of the airflow over an aircraft is less than Mach 1. The critical Mach number (Mcrit) is lowest free stream Mach number at which airflow over any part of the aircraft first reaches Mach 1. So the subsonic speed range includes all speeds that are less than Mcrit. Transonic: 0.8–1.2
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 ...
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]
Quarterhorse, the Air Force's next hypersonic aircraft, has taken an epic leap. The SR-71 Blackbird successor is a step closer to breaking the airspeed record.
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 ...
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]
