Dieselmax
The JCB Dieselmax is a streamliner car designed for the purpose of breaking the land speed record for a Diesel engine, diesel-engined vehicle. The car was built for J. C. Bamford, JCB, a British multinational equipment company. As of 2018, the car holds the world diesel-powered land speed record, having been driven to over by Wing Commander Andy Green (RAF officer), Andy Green in 2006. Design The car is powered by two specially-tuned versions of the production JCB444 powerplant, developing up to each (over five times the power output of the production version with 90 psi (6 bar) of boost) and featuring four cylinders and 5 litres of displacement, accompanied by Twin-turbo, two stage turbochargers, intercooler and aftercooler. One of the dual engines drives the front wheels while the other drives the rear. Each engine is rev-limited to 3800 rpm. As the size of the car prohibited meaningful wind tunnel testing, the streamliner, streamlined shape of the car was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ron Ayers
Ronald Frederick Ayers (11 April 1932 – 29 May 2024) was an English engineer who was responsible for the aerodynamics of the land speed record-holding vehicles, ThrustSSC and JCB Dieselmax, and was Chief Aerodynamicist for the Bloodhound SSC. Background Born in Westminster, London, England, on 11 April 1932, Ayers developed an interest during the Blitz. Ayers obtained a BSc in aeronautical engineering from the University of London and an MSc in aerodynamics from Cranfield University before starting his working career as an apprentice at Handley Page Ltd, eventually working his way up to helping design prototypes of the Handley Page Victor bomber aircraft. After that he was employed by the British Aircraft Corporation (BAC) in their Guided Weapons Division, initially as Chief Aerodynamicist and then later Head of Operational Research and Deputy Head of Management Services. Much of his time at BAC was devoted to the development of the Bloodhound surface-to-air missile. Aye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intercooler
An intercooler is a heat exchanger used to cool a gas after compression. Often found in turbocharged engines, intercoolers are also used in air compressors, air conditioners, refrigeration and gas turbines. Internal combustion engines Most commonly used with turbocharged engines, an intercooler is used to counteract the heat of compression and heat soak in the pressurised intake air. By reducing the temperature of the intake air, the air becomes denser (allowing more fuel to be injected, resulting in increased power) and less likely to suffer from pre-ignition or knocking. Additional cooling can be provided by externally spraying a fine mist onto the intercooler surface, or even into the intake air itself, to further reduce intake charge temperature through evaporative cooling. Intercoolers can vary dramatically in size, shape and design, depending on the performance and space requirements of the system. Many passenger cars use either front-mounted intercoolers locat ...

Speed Week
Bonneville Speedway (also known as the Bonneville Salt Flats Race Track) is an area of the Bonneville Salt Flats northeast of Wendover, Utah, that is marked out for motor sports. It is particularly noted as the venue for numerous land speed records. The Bonneville Salt Flats Race Track is listed on the National Register of Historic Places. The salt flats were first used for motor sports in 1912, but did not become truly popular until the 1930s when Ab Jenkins and Sir Malcolm Campbell competed to set land speed records. A reduction of available racing surface and salt thickness has led to the cancellation of events at Bonneville, such as Speed Week in 2014 and 2015. Available racing surface is much reduced with just available instead of the courses traditionally used for Speed Week. Track layouts Historically, the speedway was marked out by the Utah Department of Transportation at the start of each summer. Originally, two tracks were prepared; a long straightaway for speed t ...

JCB Fastrac
The JCB Fastrac is a high-speed agricultural tractor series manufactured by JCB Landpower, part of the JCB group. Production began in 1991, with continual development to the present day. Generally the maximum speed of most models is , but slower (40 km/h) and faster (80 km/h) versions are produced. Design Engine All models have six-cylinder diesel engines. Initially supplied by Perkins Engines then Cummins, the current supplier is AGCO SISU Power. Gearbox Three different gearboxes have been fitted to the Fastrac in production. * The first type has evolved over several years. # On introduction of the Fastrac this style of gearbox had 18 forward gears (6×3) and 6 reverse (6×1). These were organised as 6 manual gears in each of 3 ranges (Low, Medium and High). The range box also selected reverse giving 6 reverse gears with speeds similar to medium in forwards. All gear changes were made with the use of a dry clutch. # This gearbox then had a 2-speed powershift ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Vehicle Speed Records
The following is a list of speed records for various types of vehicles. This list only presents the single greatest speed achieved in each broad record category; for more information on records under variations of test conditions, see the specific article for each record category. As with many world records, there may be some dispute over the criteria for a record-setting event, the authority of the organization certifying the record, and the actual speed achieved.

Streamliner
A streamliner is a vehicle incorporating streamlining in a shape providing reduced air resistance. The term is applied to high-speed railway trainsets of the 1930s to 1950s, and to their successor " bullet trains". Less commonly, the term is applied to fully faired upright and recumbent bicycles. As part of the Streamline Moderne trend, the term was applied to passenger cars, trucks, and other types of light-, medium-, or heavy-duty vehicles, but now vehicle streamlining is so prevalent that it is not an outstanding characteristic. In land speed racing, it is a term applied to the long, slender, custom built, high-speed vehicles with enclosed wheels. Trains Before World War II Europe * Germany, 1930: The first high-speed streamliner in Germany was the '' Schienenzeppelin'', an experimental propeller-driven single car, built in 1930. On 21 June 1931, the car set a speed record of on a run between Berlin and Hamburg. In 1932 the propeller was removed and a h ...

Footnotes
In publishing, a note is a brief text in which the author comments on the subject and themes of the book and names supporting citations. In the editorial production of books and documents, typographically, a note is usually several lines of text at the bottom of the page, at the end of a chapter, at the end of a volume, or a house-style typographic usage throughout the text. Notes are usually identified with superscript numbers or a symbol.''The Oxford Companion to the English Language'' (1992) p. 709. Footnotes are informational notes located at the foot of the thematically relevant page, whilst endnotes are informational notes published at the end of a chapter, the end of a volume, or the conclusion of a multi-volume book. Unlike footnotes, which require manipulating the page design (text-block and page layouts) to accommodate the additional text, endnotes are advantageous to editorial production because the textual inclusion does not alter the design of the publication.

Bonneville Salt Flats
The Bonneville Salt Flats are a densely packed salt pan in Tooele County in northwestern Utah, United States. A remnant of the Pleistocene Lake Bonneville, it is the largest of many salt flats west of the Great Salt Lake. It is public land managed by the Bureau of Land Management and is known for land speed records at the Bonneville Speedway. The Flats is open to the public. The Flats are about 12 miles (19 km) long and 5 miles (8 km) wide, with a crust almost 5 ft (1.5m) thick at the center and less than one inch (2.5 cm) towards the edges. It is estimated to hold 147 million tons of salt, about 90% of which is common table salt. History Geologist Grove Karl Gilbert named the area after Benjamin Bonneville, a U.S. Army officer who explored the Intermountain West in the 1830s. In 1907, Bill Rishel and two local businessmen tested the suitability of the salt for driving by taking a Pierce-Arrow onto its surface. A railway line across the Flats was comp ...
