An air speed record is the highest airspeed attained by an ... which "achieved a speed of 494m.p.h. at 28,500ft during ... the highest speed ever recorded for a ...
It is highly dependent on technological advantages generating the speed of the craft, vessel or vehicle. [3] Term Overall Speed Record is also used to compare the highest momentary speed achieved by a vehicle, vessel or craft in the highest land speed, water speed or air speed contest. [4]
The X-15's highest speed, 4,520 miles per hour (7,274 km/h; 2,021 m/s), [1] was achieved on 3 October 1967, [2] when William J. Knight flew at Mach 6.7 at an altitude of 102,100 feet (31,120 m), or 19.34 miles. This set the official world record for the highest speed ever recorded by a crewed, powered aircraft, which remains unbroken. [3] [4]
ThrustSSC, driven by Royal Air Force pilot Andy Green, holds the current land speed record at 1,227.986 km/h (763.035 mph) set October 15, 1997.. The land speed record (LSR) or absolute land speed record is the highest speed achieved by a person using a vehicle on land.
Some publications cite the F1's timed top speed as 240.1 mph (386.4 km/h). This speed was achieved by a modified F1 with the rev limiter raised from 7500 rpm to 8300 rpm, not a production car. [20] The F1 in an unmodified state is gear limited at 221 mph (356 km/h). 1993 Dauer 962 Le Mans: 404.6 km/h (251.4 mph) [21]
Scramjets only operate at speeds in the range of Mach 4.5 or higher, so rockets or other jet engines are required to initially boost scramjet-powered aircraft to this base velocity. In the case of the X-43A, the aircraft was accelerated to high speed with a Pegasus rocket launched from a converted Boeing B-52 Stratofortress bomber. The combined ...
An L0 Series trainset, holding the non-conventional train world speed record of 603 km/h (375 mph) TGV 4402 (operation V150) reaching 574.8 km/h (357 mph). The world record for a conventional wheeled passenger train is held by a modified French TGV high-speed (with standard equipment) code named V150, set in 2007 when it reached 574.8 km/h (357.2 mph) on a 140 km (87 mi) section of track.
