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] Reentry vehicle (RV) after an 8,000 ...
The Arrow 3 or Hetz 3 (Hebrew: חֵץ 3, pronounced [ˈχet͡s] or pronounced [ˈħet͡s]) is an exoatmospheric hypersonic anti-ballistic missile, jointly funded, developed and produced by Israel and the United States. Undertaken by Israel Aerospace Industries (IAI) and Boeing, it is overseen by the Israeli Ministry of Defense's " Homa ...
The Whitcomb area rule, named after NACA engineer Richard Whitcomb and also called the transonic area rule, is a design procedure used to reduce an aircraft 's drag at transonic speeds which occur between about Mach 0.75 and 1.2. For supersonic speeds a different procedure called the supersonic area rule, developed by NACA aerodynamicist Robert ...
A hypersonic weapon is a weapon capable of travelling at hypersonic speed, defined as between 5 and 25 times the speed of sound or about 1 to 5 miles per second (1.6 to 8.0 km/s). [ 1 ] Below such speeds, weapons would be characterized as subsonic or supersonic , while above such speeds, the molecules of the atmosphere disassociate into a ...
NASA Langley's Hypersonic Facilities Complex, 1969. A hypersonic wind tunnel is designed to generate a hypersonic flow field in the working section, thus simulating the typical flow features of this flow regime - including compression shocks and pronounced boundary layer effects, entropy layer and viscous interaction zones and most importantly high total temperatures of the flow.
Hypersonic glide vehicle. Chinese DF-ZF hypersonic glide vehicle mounted on the DF-17 ballistic missile. A hypersonic glide vehicle (HGV) is a type of warhead for ballistic missiles that can maneuver and glide at hypersonic speed. It is used in conjunction with ballistic missiles to significantly change their trajectories after launch.
Technology developed for the HAWC demonstrator was used to influence the design of the HACM, a U.S. Air Force Program of Record to create a scramjet-powered hypersonic missile it could deploy as an operational weapon. [8] In December 2021, Raytheon Technologies was awarded a $985 million contract to continue its HACM development. [9]
