Explorations of Automotive Design: The fastest vehicle on the land

By Ryan

Supersonic seems only belongs to planes, but not many people know that cars can break sonic barrier as well.

In 1983 Richard Noble had broken the world land speed record 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

The car was driven by Royal Air Force fighter pilot Wing Commander Andy Green in the Black Rock Desert in the state of Nevada. It was powered by two afterburning 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 liters/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 5,500 l/100 km (0.05 mpg-imp; 0.04 mpg-US).

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 (located in Ma'an Governorate) in 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.
