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).
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 Boom XB-1 "Baby Boom" is a one-third-scale trijet supersonic demonstrator designed by Boom Technology as part of the development of the Boom Overture supersonic transport airliner. Powered by three General Electric J85 engines, [ 2 ] it is designed to maintain a speed of Mach 2.2, with over 1,000 nautical miles (1,900 km; 1,200 mi) of range.
Manned by Boom Supersonic's chief test pilot Tristan "Geppetto" Brandenburg, the XB-1 launched in the early hours of Tuesday, reaching an altitude of 35,290 feet and accelerating to speed Mach 1. ...
(Reuters) - About 35,000 feet (10,670 meters) over the Mojave Desert, northwest of Los Angeles, Boom Supersonic's XB-1 became the first privately funded airplane to break the sound barrier during ...
The preliminary design review was originally planned to be completed by June 2017. [5] While NASA received three inquiries for its August 2017 request for proposals, Lockheed was the sole bidder. [6] On April 2, 2018, NASA awarded Lockheed Martin a $247.5 million contract to design, build and deliver in late 2021 the Low-Boom X-plane.
Entering limited production from 2001, the Block I was designed to provide 360-degree coverage against airborne threats up to supersonic speed. The Block I was reportedly the first Vertical Launch System Infrared surface-to-air missile to be developed anywhere in the world, also being the first to operate a lock-on after launch mode.
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. [9] 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. [ 9 ]
