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 ...
Supersonic speed is the speed of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately 343.2 m/s (1,126 ft/s; 768 mph; 667.1 kn; 1,236 km/h). Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic.
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 ...
Mach number. Ratio of speed of an object moving through fluid and local speed of sound. The Mach number (M or Ma), often only Mach, (/ mɑːk /; German: [max]) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. [1][2] It is named after the Austrian physicist and ...
Starship flight test 4 was the fourth flight test of the SpaceX Starship launch vehicle. The prototype vehicles flown were the Starship Ship 29 upper-stage and Super Heavy Booster 11. [ 4 ][ 5 ] SpaceX performed the flight test on June 6, 2024. The main test objectives of this flight, both of which were accomplished, were for the Super Heavy ...
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 ...
The X-15 was built by two manufacturers: North American Aviation was contracted for the airframe in November 1955, and Reaction Motors was contracted for building the engines in 1956. Like many X-series aircraft, the X-15 was designed to be carried aloft and drop launched from under the wing of a B-52 mother ship.
