The first supersonic land speed record was set by Andy Green in Thrust SCC (United Kingdom) on On 15 October 1997, exactly 50 years and 1 day afterChuck Yeager first broke the sound barrier in the Earth’s atmosphere. ThrustSSC, Thrust SSC, or Thrust supersonic car, is a British jet-propelled cardeveloped by Richard Noble, Glynne Bowsher, Ron Ayers and Jeremy Bliss. Thrust SSC holds the World Land Speed Record, set on 15 October 1997, when it achieved a speed of 1,228 km/h (763 mph) and became the first car to officially break the sound barrier.
The car was driven by Royal Air Force fighter pilot Wing Commander Andy Green in the Black Rock Desert in Nevada, United States. It was powered by twoafterburning Rolls-Royce Spey turbofan engines, as used in the British version of the F-4 Phantom II jet fighter. The car was 16.5 m (54 ft) long, 3.7 m (12 ft) wide and weighed 10.5 tons (10.7 t), and the twin engines developed a net thrust of 223 kN (50,000 lbf), a power output of 110,000 bhp (82MW), burning around 18 litres per second (4.0 Imperial gallons/s or 4.8 US gallons/s). Transformed into the usual terms for car mileages based on its maximum speed, the fuel consumption was about 55 L/km (0.05 mpg-imp; 0.04 mpg-US). By comparison, the Concorde burned about 0.8 gallons/sec (10500 kg/h, 2885 gallons/hr) at full power, with typical 17 miles per U.S. gallon (14 L/100 km; 20 mpg-imp) per passenger (100 passengers were maximum capacity). The record run in October 1997 was preceded by extensive test runs of the vehicle in Autumn 1996 and Spring 1997 in the Al-Jafr desert, Jordan, a location unknown before for its capabilities as a test range for high speed land vehicles, with numerous advantages compared to the salt deserts of the Western United States
Richard Noble broke the world land speed record in 1983 with his earlier car Thrust2, which reached a speed of 1,018 km/h (633 mph). The date of Andy Green’s record came exactly a half century and one day after Chuck Yeager broke the sound barrier in Earth’s atmosphere, with the Bell X-1 research rocket plane on 14 October 1947. Both Thrust SSC and Thrust2 are displayed at the Coventry Transport Museum in Coventry, England. Thrust SSC is housed in a barrel-roofed hall. Visitors can board the pit trailer from which Thrust SSC runs were controlled, and can ride a motion simulator depicting a computer-generated animation of the record-breaking run from the perspective of Green.Several teams are competing to break the record, including Richard Noble’s Bloodhound SSC project and the North American Eagle project. I was lucky enough to see the Bloodhound SSC At this years Cosford Air Show.
