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 ...
A BGM-109 Tomahawk flying in November 2002. A cruise missile is an unmanned self-propelled guided vehicle that sustains flight through aerodynamic lift for most of its flight path and whose primary mission is to place an ordnance or special payload on a target. [1] Cruise missiles are designed to deliver a large warhead over long distances with ...
Contents. Avangard (hypersonic glide vehicle) The Avangard (Russian: Авангард, "Vanguard"; previously known as Objekt 4202, Yu-71 and Yu-74) is a Russian hypersonic glide vehicle (HGV) that can be carried as an MIRV payload by the UR-100UTTKh, [ 9 ][ 10 ] R-36M2 and RS-28 Sarmat heavy ICBMs. It can deliver both nuclear and conventional ...
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 ...
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.
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 ...
The DARPA FALCON Project (Force Application and Launch from Continental United States) was a two-part joint project between the Defense Advanced Research Projects Agency (DARPA) and the United States Air Force (USAF) and is part of Prompt Global Strike. [1] The first part of the project aimed to develop a Small Launch System (SLS) capable of ...
