Turbojet Train
A turbojet train is a train powered by turbojet engines. Like a jet aircraft, but unlike a gas turbine locomotive, the train is propelled by the jet thrust of the engines, rather than by its wheels. Only a handful of jet-powered trains have been built, for experimental research in high-speed rail. Turbojet engines have been built with the engine incorporated into a railcar combining both propulsion and passenger accommodation rather than as separate locomotives hauling passenger coaches. As turbojet engines are most efficient at high speeds, the experimental research has focused in applications for high-speed passenger services, rather than the heavier trains (with more frequent stops) used for freight services. M-497 The first attempt to use turbojet engines on a railroad was made in 1966 by the New York Central Railroad (NYCR), a company with operations throughout the Great Lakes region. They streamlined a Budd Rail Diesel Car, added two General Electric J47-19 jet engin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Linear Induction Motor
A linear induction motor (LIM) is an alternating current (AC), asynchronous linear motor that works by the same general principles as other induction motors but is typically designed to directly produce motion in a straight line. Characteristically, linear induction motors have a finite primary or secondary length, which generates end-effects, whereas a conventional induction motor is arranged in an endless loop. Despite their name, not all linear induction motors produce linear motion; some linear induction motors are employed for generating rotations of large diameters where the use of a continuous primary would be very expensive. As with rotary motors, linear motors frequently run on a three-phase power supply and can support very high speeds. However, there are end-effects that reduce the motor's force, and it is often not possible to fit a gearbox to trade off force and speed. Linear induction motors are thus frequently less energy efficient than normal rotary motors for an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railcars Of Russia
A railcar (not to be confused with the generic term railroad car or railway car) is a self-propelled railway vehicle designed to transport passengers. The term "railcar" is usually used in reference to a train consisting of a single coach (or carriage, car, unit), with a driver's cab at one or both ends. In its simplest form, a "railcar" may also be little more than a motorized railway handcar, draisine or railbus. Some railway companies, such as the Great Western, termed such vehicles "railmotors" (or "rail motors"). Self-powered railcars were once common in North America; and termed Doodlebugs. Self-propelled passenger vehicles also capable of hauling a train are, in technical rail usage, more usually called "rail motor coaches" or "motor cars" (not to be confused with the motor cars, otherwise known as automobiles, that operate on roads). Alternative use In Australia, the term is sometimes also used as an alternative name for the small types of multiple unit whi ...

Jet Engines
A jet engine is a type of reaction engine, discharging a fast-moving jet (fluid), jet of heated gas (usually air) that generates thrust by jet propulsion. While this broad definition may include Rocket engine, rocket, Pump-jet, water jet, and hybrid propulsion, the term typically refers to an internal combustion airbreathing jet engine, air-breathing jet engine such as a turbojet, turbofan, ramjet, pulse jet engine, pulse jet, or scramjet. In general, jet engines are internal combustion engines. Air-breathing jet engines typically feature a Axial compressor, rotating air compressor powered by a turbine, with the leftover power providing thrust through the propelling nozzle—this process is known as the Brayton cycle, Brayton thermodynamic cycle. Jet aircraft use such engines for long-distance travel. Early jet aircraft used turbojet engines that were relatively inefficient for subsonic flight. Most modern subsonic jet aircraft use more complex High-bypass turbofan, high-bypas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Turbine Multiple Units
Gas is a state of matter that has neither a fixed volume nor a fixed shape and is a compressibility, compressible fluid. A ''pure gas'' is made up of individual atoms (e.g. a noble gas like neon) or molecules of either a single type of atom (chemical element, elements such as oxygen) or from different atoms (chemical compound, compounds such as carbon dioxide). A ''gas mixture'', such as air, contains a variety of pure gases. What distinguishes gases from liquids and solids is the vast separation of the individual gas particles. This separation can make some gases invisible to the human observer. The gaseous state of matter occurs between the liquid and plasma states, the latter of which provides the upper-temperature boundary for gases. Bounding the lower end of the temperature scale lie degenerative quantum gases which are gaining increasing attention. High-density atomic gases super-cooled to very low temperatures are classified by their statistical behavior as either Bose ga ...

Turboshaft
A turboshaft engine is a form of gas turbine that is optimized to produce shaft horsepower rather than jet thrust. In concept, turboshaft engines are very similar to turbojets, with additional turbine expansion to extract heat energy from the exhaust and convert it into output shaft power. They are even more similar to turboprops, with only minor differences, and a single engine is often sold in both forms. Turboshaft engines are commonly used in applications that require a sustained high power output, high reliability, small size, and light weight. These include helicopters, auxiliary power units, boats and ships, tanks, hovercraft, and stationary equipment. Overview A turboshaft engine may be made up of two major parts assemblies: the 'gas generator' and the 'power section'. The gas generator consists of the Gas compressor, compressor, combustion chambers with ignitors and fuel nozzles, and one or more stages of turbine. The power section consists of additional stages of turbi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schienenzeppelin
The () or rail zeppelin was an experimental railcar which resembled a Zeppelin airship in appearance. It was designed and developed by the German aircraft engineer Franz Kruckenberg in 1929. Propulsion was by means of a pusher propeller located at the rear: it accelerated the railcar to setting the land speed record for a petrol powered rail vehicle. Only a single example was ever built, which due to safety concerns remained out of service and was finally dismantled in 1939. History Anticipating the design of the Schienenzeppelin, the earlier Aerowagon, an experimental Russian high-speed railcar, was also equipped with an aircraft engine and a propeller. The railcar was built at the beginning of 1930 in the Hannover-Leinhausen works of the German Imperial Railway Company (''Deutsche Reichsbahn''). The work was completed by autumn of the same year. The vehicle was long and had just two axles, with a wheelbase of . The height was . As originally built it had two conjoin ...

Aerowagon
The Aerowagon or Aeromotowagon () was an experimental high-speed railcar fitted with an aircraft engine and propeller traction invented by Valerian Abakovsky, a Soviet engineer from Latvia. It produced speeds of up to . The Aerowagon was originally intended for the express transportation of important documents and to carry Soviet officials on government business. Crash incident On 24 July 1921, a group of delegates to the First Congress of the Profintern,The Communist International, organ of the Executive Committee of the Communist International, no.19, 921/ref> led by Fyodor Sergeyev, took the Aerowagon from Moscow to the Tula collieries to meet with local miners and to visit an arms factory. Abakovsky was also on board. Although they successfully arrived in Tula, on the return route to Moscow the Aerowagon derailed at high speed near Serpukhov, killing six of the 22 people on board. A seventh man ( Paul Freeman) later died of his injuries.Letters from Tom Mann to Elsie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aérotrain
The Aérotrain was an experimental Tracked Air Cushion Vehicle (TACV), or hovertrain, developed in France from 1965 to 1977 under the engineering leadership of Jean Bertin (1917–1975) – and intended to bring the French rail network to the cutting edge of land-based public transportation. Though similar to a maglev design, which levitates a train car over a complex electromagnetic track to eliminate all resistance other than aerodynamic drag, the Aérotrain – also a "train without wheels" – rode on an air cushion over a simple reinforced concrete track or ''guideway'' and could travel at the speed of a maglev train, without the further technical complexity and expense of its track. In many respects, the entire concept resembled a product of the aircraft rather than rail industry. History In 1969, a U.S. company, Rohr Industries, licensed the Aérotrain technology to build the hovertrains in the United States. That same year the Aérotrain established the world rec ...
