ALFA-X
The , branded "ALFA-X", is a ten-car experimental Shinkansen train operated by East Japan Railway Company (JR East) in Japan to test technology to be incorporated into future trains operating at speeds of up to . The name is an acronym for "Advanced Labs for Frontline Activity in rail eXperimentation". The first train was unveiled on May 9, 2019. The Plarail (series of toy trains) "Ippai Tsunago" Shinkansen Test Train ALFA-X began to be sold on December 26, 2019. Its test run is mainly performed in sections between Sendai and Shin-Aomori of the Tohoku Shinkansen line, and, in some cases, on the Hokkaido Shinkansen line. Design The experimental trainset is being tested at speeds of up to around to evaluate new technologies to be incorporated into new trains to operate in revenue service at speeds of up to . These technologies include dampers to reduce vibration and the likelihood of derailment in major earthquakes. It also tests body designs that reduce snow adherence. The ...

Shinkansen Train Series
The , colloquially known in English as the bullet train, is a network of high-speed railway lines in Japan. Initially, it was built to connect distant Japanese regions with Tokyo, the capital, to aid economic growth and development. Beyond long-distance travel, some sections around the largest metropolitan areas are used as a commuter rail network. It is operated by five Japan Railways Group companies. Over the Shinkansen's 50-plus-year history, carrying over 10 billion passengers, there has been not a single passenger fatality or injury on board due to derailments or collisions. Starting with the Tokaido Shinkansen () in 1964, the network has expanded to currently consist of of lines with maximum speeds of , of Mini-Shinkansen lines with a maximum speed of , and of spur lines with Shinkansen services. The network presently links most major cities on the islands of Honshu and Kyushu, and Hakodate on northern island of Hokkaido, with an extension to Sapporo under ...

A total of 59 10-car sets are on order, with three sets in service in time for the start of new ''Hayabusa'' services to Shin-Aomori in March 2011. The H5 series, a cold-weather derivative of the E5 series, is operated by Hokkaido Railway Company (JR Hokkaido); it has been in use on Tohoku and Hokkaido Shinkansen services since 26 March 2016. Ordered in February 2014, a total of four 10-car sets were built by Hitachi and Kawasaki Heavy Industries at a cost of approximately . The first two sets were delivered in October 2014. Design Technology incorporated in these trains is derived from the experimental Fastech 360S train tested by JR East. The initial maximum speed in servi ...

Experimental And Prototype High-speed Trains
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experimental studies. A child may carry out basic experiments to understand how things fall to the ground, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and informal natural comparisons (e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Air Brake (aeronautics)
In aeronautics, air brakes or speed brakes are a type of flight control surface used on an aircraft to increase the drag on the aircraft. Air brakes differ from spoilers in that air brakes are designed to increase drag while making little change to lift, whereas spoilers reduce the lift-to-drag ratio and require a higher angle of attack to maintain lift, resulting in a higher stall speed. Introduction An air brake is a part of an aircraft. When extended into the airstream, it causes an increase in the drag on the aircraft. When not in use, it conforms to the local streamlined profile of the aircraft in order to help minimise the drag. History In the early decades of powered flight, air brakes were flaps mounted on the wings. They were manually controlled by a lever in the cockpit, and mechanical linkages to the air brake. An early type of air brake, developed in 1931, was fitted to the aircraft wing support struts. In 1936, Hans Jacobs, who headed Nazi Germany's ' ...

Eddy Current Brake
An eddy current brake, also known as an induction brake, electric brake or electric retarder, is a device used to slow or stop a moving object by generating eddy currents and thus dissipating its kinetic energy as heat. Unlike friction brakes, where the drag force that stops the moving object is provided by friction between two surfaces pressed together, the drag force in an eddy current brake is an electromagnetic force between a magnet and a nearby conductive object in relative motion, due to eddy currents induced in the conductor through electromagnetic induction. A conductive surface moving past a stationary magnet develops circular electric currents called eddy currents induced in it by the magnetic field, as described by Faraday's law of induction. By Lenz's law, the circulating currents create their own magnetic field that opposes the field of the magnet. Thus the moving conductor experiences a drag force from the magnet that opposes its motion, proportional to its v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
