Record car Thrust SSC reaches a speed of 100 kilometers per hour literally in a split second, which is due to the colossal thrust of two aircraft turbojet engines Rolls-Royce Spey. Unlike production cars, where acceleration to the first hundred takes a few seconds, here this section of the road is covered almost instantly after starting to move. The engineering concept of the car excluded a smooth increase in speed, since the main goal was to overcome the sound barrier, and not a comfortable ride on public roads.
The power of the power plant is about 110,000 horsepower, which makes any comparisons with conventional vehicles incorrect. When the engines are running at full power, the acceleration is so great that the pilot experiences the g-forces typical of fighter jets. That's why the question of how long it takes Thrust SSC for acceleration to 100 km/h, is rather theoretical in nature, since in real races this speed is only the initial stage of acceleration before reaching maximum performance.
To control such a machine, not only the reaction of the pilot was required, but also the most complex electronics that controlled the operation of the turbines. Any wrong movement or failure in the control system could lead to catastrophic consequences due to the monstrous energy released when burning fuel. Below we will take a closer look at the technical aspects that allow this unique device to achieve such speeds.
Technical characteristics of the power plant
The basis of dynamics Thrust SSC are two gas turbine engines Rolls-Royce Spey 205, which were previously installed on F-4 Phantom II fighters. These units were not chosen by chance: they are highly reliable and capable of developing thrust sufficient to overcome air resistance at supersonic speeds. Each engine weighs about 1,800 kilograms, requiring a reinforced chassis and frame structure for the vehicle.
The car's fuel system must supply kerosene under high pressure, ensuring stable combustion in the combustion chamber even under extreme overloads. For this purpose, special pumps and nozzles are used, designed to operate in conditions of vibration and high temperatures. The total fuel reserve is about 900 liters, which allows the machine to operate at full power for only a few minutes.
The cooling system also plays a critical role as exhaust gas temperatures reach thousands of degrees. Engineers have developed special heat dissipation channels to protect the body and internal components from thermal damage. Without effective cooling, engine operation at high speed would be impossible.
- 🚀 Two Rolls-Royce Spey 205 turbojet engines provide a total thrust of over 100 kN.
- ⛽ The fuel supply system uses aviation kerosene and is designed for short-term operation at maximum.
- ❄️ A specialized cooling system protects critical components from overheating when forced.
Spey engine parts
Spey 205 engines were chosen for their affordability and proven reliability. They have a dual-circuit design, which slightly reduces fuel consumption compared to single-circuit analogues, but at the speed of sound the operating efficiency changes.
Aerodynamics and stability at high speeds
When driving at speeds approaching sound speed, aerodynamic forces become the dominant factor influencing the vehicle's behavior. Form Thrust SSC was designed to minimize drag and prevent lift that could lift the vehicle off the ground. The body has an elongated cigar-shaped shape, which is optimal for supersonic flights.
The most important element is the stabilization system, which includes vertical and horizontal keels. These elements help maintain directional stability, especially when passing through the transonic transition zone where shock waves occur. Errors in aerodynamic calculations could lead to uncontrolled rotation or capsizing of the device.
The wheels of the car are made of a special aluminum alloy and have a unique design that can withstand centrifugal forces when rotating at speeds of more than 10,000 revolutions per minute. Tires are not used because rubber tires would not withstand such loads and temperatures. Contact with the ground is carried out through all-metal discs, which requires a perfectly flat track surface.
⚠️ Attention: At speeds above 800 km/h, any obstacle on the road the size of a stone can lead to the destruction of the rim and loss of control.
The launch process and preparation for the record race
Preparation Thrust SSC the race begins long before the engines start. Engineers conduct a thorough check of all systems, including hydraulics, electronics and fuel lines. Starting jet engines is a complex process that requires sequential steps to avoid surge or overheating.
Initially, the starter is started, which spins the turbine shaft to a certain speed. After reaching the required speed, fuel is supplied and ignited by a spark. From this moment on, the engine begins to work independently and the starter is turned off. The pilot controls engine operating parameters through the on-board monitoring system.
☑️ Pre-launch preparation checklist
After the engines warm up, the car slowly moves to the starting position. Acceleration starts smoothly to avoid slipping on the loose soil of the salt marsh, but quickly moves into maximum acceleration mode. The pilot must accurately dose the thrust so as not to lose traction.
Comparison of dynamics with other record-breaking cars
To understand the scale of achievements Thrust SSC It is useful to compare his performance with other famous speed record holders. If early record-breaking cars used piston internal combustion engines, modern vehicles have switched to jet propulsion. This allowed us to radically change the dynamics of acceleration and the maximum achievable speeds.
| Car | Engine type | Record year | Max. speed (km/h) |
|---|---|---|---|
| Thrust SSC | Jet (2x) | 1997 | 1227.99 |
| Thrust2 | Jet (1x) | 1983 | 1019.47 |
| Blue Bird CN7 | Gas turbine | 1964 | 648.73 |
| Railton Mobil Special | Piston (2x) | 1947 | 634.39 |
As can be seen from the table, the transition to jet propulsion made it possible to overcome the psychological and physical barrier of 1000 km/h. Thrust2, the predecessor of the SSC, also used a jet engine, but a single turbine was not enough to break the sound barrier. Doubling power and improving aerodynamics were key success factors.
The role of the pilot and acceleration acceleration
Management Thrust SSC requires from the pilot not only driving skills, but also excellent physical fitness. During acceleration and braking, significant overloads occur that affect the human body. Pilot Andy Green, who set the record, underwent special training similar to that of astronauts.
In the cockpit, the pilot sits in a special seat with seat belts that secure the body. The steering is controlled via a joystick, as a traditional steering wheel would be ineffective at such speeds and overloads. Visual control of the track is difficult due to vibration and dust, so the pilot relies on instruments and a pre-marked track.
⚠️ Attention: Overloads during sudden maneuvering at supersonic speed can lead to loss of consciousness by the pilot, so all movements must be smooth and calculated.
The ground communication system allows engineers to monitor the machine's condition in real time and provide recommendations to the pilot. However, at the moment of passing the record zone, the pilot acts autonomously, relying on his training and intuition. Making a mistake in calculations at such a speed means a fatal outcome.
Braking and stopping the record car
After passing the one-mile measuring section, the pilot is faced with the task of stopping the car safely. Braking Thrust SSC carried out using a parachute system and aerodynamic resistance. Mechanical brakes on wheels are practically not used due to the risk of their destruction due to temperature.
Immediately after the finish line, the pilot releases drag parachutes, which sharply increase drag. This allows you to quickly reduce speed to a level where it is possible to use the wheel brakes to come to a complete stop. The braking process takes several kilometers and requires a wide and level area.
To stop, two parachutes are used with a total area of more than 60 square meters, which is equivalent to the area of a small apartment.
The effectiveness of braking depends on the condition of the salt marsh surface. If the ground is too soft, the wheels may become stuck, causing the vehicle to tip over. If it is too hard, there is a risk of damage to the discs. Therefore, route selection and surface preparation are no less important than engine tuning.
Safely stopping a 10-tonne machine at the speed of sound is no less difficult than achieving a record.
