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.
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 ...
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 ...
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.
Classification. In 1990, air historian Richard P. Hallion proposed a classification of jet fighters into six generations up to that time. These may be broadly described as subsonic, transonic, supersonic, Mach 2, multi-mission, and high-manoeuverability. [ 2 ] Other schemes comprising five generations up to around the same period have since ...
The Lockheed Martin X-59 Quesst ("Quiet SuperSonic Technology"), sometimes styled QueSST, is an American experimental supersonic aircraft under development by Skunk Works for NASA 's Low- Boom Flight Demonstrator project. [ 1 ] Preliminary design started in February 2016, with the X-59 planned to begin flight testing in 2021.
ThrustSSC, Thrust SSC or Thrust SuperSonic Car is a British jet car developed by Richard Noble, Glynne Bowsher, Ron Ayers, and Jeremy Bliss. [1] Thrust SSC holds the world land speed record , set on 15 October 1997, and driven by Andy Green , when it achieved a speed of 1,228 km/h (763 mph) and it became the first and only land vehicle to ...
The Rockwell B-1 Lancer[b]is a supersonic variable-sweep wing, heavy bomberused by the United States Air Force. It has been nicknamed the "Bone" (from "B-One"). [2][3]As of 2024[update], it is one of the United States Air Force's three strategic bombers, along with the B-2 Spiritand the B-52 Stratofortress. Its 75,000-pound (34,000 kg) payload ...
