At Mach 0.65, u is 65% of the speed of sound (subsonic), and, at Mach 1.35, u is 35% faster than the speed of sound (supersonic). An F/A-18 Hornet creating a vapor cone at transonic speed just before reaching the speed of sound. The local speed of sound, and hence the Mach number, depends on the temperature of the surrounding gas.
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. All commercial aircraft — Transonic [0.8–1.2) 614–921 mph (988–1,482 km/h; 274–412 m/s)
Oreshnik (Russian: Орешник, lit. 'Hazel tree'), [2] is a Russian intermediate-range ballistic missile (IRBM) characterized by its reported speed exceeding Mach 10 (12,300 km/h; 7,610 mph; 3.40 km/s), according to the Ukrainian military.
The Pegasus rocket booster separated from its B-52 carrier at 40,000 feet and its solid rocket took the combination to Mach 10 at 110,000 feet. [8] The X-43A split away at Mach 9.8 and the engine was started at Mach 9.65 for 10–12 seconds with thrust approximately equal to drag, and then glided to the Pacific Ocean after 14 minutes. [8]
As the RV would be traveling at about 5 miles per second (8,047 m/s; 26,400 ft/s; Mach 24), Sprint needed to have phenomenal performance to achieve an interception in the few seconds before the RV reached its target. Sprint accelerated at 100 g, reaching a speed of Mach 10 (12,000 km/h; 7,600 mph) in 5 seconds. Such a high velocity at ...
The DF-ZF is thought to reach speeds between Mach 5 (3,836 mph (6,173 km/h; 1,715 m/s)) and Mach 10 (7,680 mph (12,360 km/h; 3,430 m/s)). [5] The glider could be used for nuclear weapons delivery but could also be used to perform precision-strike conventional missions (for example, next-generation anti-ship ballistic missiles), which could penetrate "the layered air defenses of a U.S. carrier ...
Mach 10 or variation, may refer to: Mach number for ten times the speed of sound Hypersonic speed of 10 times the speed of sound; Mach 10 Training Systems, a coaching consultancy of James McCallum (cyclist) "Mach 10" (song), a 2007 song by Dub Pistols off the album Speakers and Tweeters; MachTen, a Unix-like operating system based on BSD and ...
[4] [5] It has an estimated range of 460–480 km (290–300 mi) [6] and a reported top speed of Mach 10. [3] [6] It can carry either conventional or nuclear warheads [7] and can be launched by Tu-22M3 bombers, MiG-31K interceptors, or modified Su-34 fighter-bombers. It is the first hypersonic weapon used in combat. [8]
