HISTORY OF TECHNOLOGY, TECHNOLOGY, OBJECTS AROUND US
Jet car TRUST SSC. History of invention and production
Directory / The history of technology, technology, objects around us On August 21, 1991, El Teague drove a car of his own design, the Speed-O-Motive Spirit of 76, to 684,322 kilometers per hour across the Bonneville Salt Flats (Utah, USA). This is the current speed record for wheel-driven vehicles. Until now, some people believe that the wheel drive has not exhausted itself and he will still have the last word, and in general there is no limit to perfection. But, in any case, we must admit: they cannot be compared in speed with jet cars.
By itself, jet ground transport is potentially quite safe, but ... depending on what speed. According to theory, any object that exceeds the speed of 330 meters per second (1188 kilometers per hour) under standard conditions (that is, at sea level at room temperature and normal atmospheric pressure) generates powerful mechanical vibrations. The latter, of course, reach the ground under the car, then the waves of variable pressure reflected from it hit its bottom ... In 1979, Stan Barrett raced his Budweiser Rocket at near-sonic speeds across the Edwards Air Force Base. According to the official report, the rear wheels literally bounced off the ground and Barrett was thrown out of his seat well before the end of the run. The new generation of supersonic vehicles is more like a squadron of small fighter planes. The aforementioned mechanical vibration is damped by the tubular fuselage, and the ailerons keep the vehicle from leaving the ground. In 1983, Englishman Richard Noble officially set the land speed world record in a Trust II jet: 1019,26 kilometers per hour. From the cherished limit - the speed of sound - it was separated by some 169 kilometers per hour! But fifteen years passed, when at last the dream of many racers came true and the sound barrier was broken. In the struggle to overcome the "supersonic" was attended by several famous racers and firms. Art Arfons became famous for 26 (!) models of racing cars with aircraft engines. The entire series was designed by designer John Dear Green, therefore it was called Green Monster. The first "monster", built at home in 1965 and equipped with a "General Electric J79-GE-15A" turbojet engine, brought Arfons his first victory - no less, 923,2 kilometers per hour! In November 1966 - another world record: 976 kilometers per hour! To overcome the new frontier, Arfons prepared a nice, swift and rather compact creation of only 8 meters in length with a small jet engine with a capacity of 9000 horsepower. The frame is made of chrome-molybdenum tubes wrapped in Kevlar and fiberglass. Two front wheels without Alcoa forged aluminum alloy tires are arranged in tandem. The rear wheels were put overboard, each on a rigid support. This mini-monster was painted, of course, in an American way - in red, white and blue. The famous company "McLaren" in the framework of the McLaren Advanced Vehicle program has prepared the project "Maverick". The car is a giant with a length of 14, a width of 8,1 and a height of 3,3 meters, weighing a good 2,5 tons, of which a third falls on the Rolls-Royce engine with a capacity of 36000 horsepower. According to the calculations of engineers, the gas turbine was supposed to accelerate the car to 40 kilometers per hour in 1360 seconds. The body of the car was made from Kevlar and carbon fiber. The driver, like a fighter pilot, is strapped into an ejector seat programmed to eject in an emergency. Unlike most other supersonic cars that use a profiled suspension, the McLaren one was equipped with a computerized active one, like the famous Formula 1 car of the same company. Engineers convinced: with such "weapons" "McLaren" will easily overshoot the coveted bar of speed. Craig Breedlove is a truly great racer, the first to break 600, 800, and then 900 kilometers per hour. From 1963 to 1970, he became world champion five times, his name became a household name. Then he retired from big sport for a long time and lived in California, gradually getting richer in real estate transactions. But closer to sixty, the "brave Breedlove" was again on everyone's lips, having invested six million dollars in the construction of the super-fast car "Spirit of America". The ex-champion hired eight employees of his own small shop in the small provincial town of Rio Vista. The monster he created was 13,7 meters long, 2,5 meters wide and weighing 4 tons. It has a central fuselage and two tail wings. The frames of the fuselage, wings and fairings were welded from steel pipes. The bulkheads and decking were made from Alcoa's proprietary aluminum alloy. The nose ahead of the cockpit was sharpened and provided with two air intakes feeding a 48000 horsepower jet engine. The F-4 Phantom fighter flies on the same. Breedlove's pride was tires made of graphite-based composite material, equipped with a cord belt and specially designed for speeds of the order of 1350 kilometers per hour ... However, success did not come to Craig Breedlove, McLaren or Art Arfons. The Englishman Noble could not allow someone else to break his record. Noble developed a new model, the Trust SSC (super-sonic car), a traction supersonic car. It was made supersonic by two "Rolls-Royce" jet engines "Spey 205" with a total capacity of 110000 horsepower. The driver's seat was located between them, the aircraft-type steering was placed in the tail. The front wheels are on the sides of the engines, the four rear (steering) wheels are staggered under the tail. The body is made of Kevlar and carbon fiber. True, Noble himself did not sit at the helm of the car - he generously gave way to the pilot of the English Royal Air Fleet Andrew Green, taking on the functions of coordinator-observer. A 21-kilometer path was marked at the bottom of a dry lake in Nevada (USA). The race car weighing ten tons was delivered to Nevada on a Russian transport plane. And, finally, for the first time, a ground vehicle - a jet car - broke the sound barrier. Green on Trust SSC developed a speed of 15 kilometers per hour on October 1997, 1227,985. The rolling thump from the sound barrier was heard in the town about 20 kilometers from the place of arrival, and the walls trembled in the houses. Now fighter pilot Andy Green appears as "the fastest man on Earth." He tells the story of his record this way: “One morning my friend Jane was reading the Sunday Telegraph in bed. It told about Richard Noble, who wanted to break the supersonic barrier in a car. He was looking for someone who would agree to pilot it. “He is crazy - I thought, and then suddenly decided: - If they are going to use Rolls-Royce Spey 202 jet engines and want to reach speeds of 1200 kilometers per hour, then I will sit behind the wheel of such a car. "After six months of testing, I got a place. On October 1997, 0, I was at the Black Rock Desert in Nevada, crammed into the cockpit of a Trust SSC, hands on the steering wheel, right foot ready to press the gas pedal. In front of me was the largest tachometer with a scale from 1000 to 0 miles per hour (1600-320 kilometers per hour). When the engine started, I realized that it was not so easy to keep a ten-ton monster that flies at the speed of a rocket on a straight line. My butt was ten centimeters off the ground, and it was a terrible feeling. The car went with crazy acceleration, increasing the speed from 960 to 900 kilometers per hour in less than twenty seconds. At around XNUMX kilometers per hour, the car became even worse and became almost uncontrollable. I remember the eerie howl of air waves forming over the cockpit, I remember the ground rushing under me at incredible speed. I drove a kilometer in three seconds. It was the most wonderful adventure of my life." Author: Musskiy S.A.
