Franz Kruckenberg
Franz Friedrich Kruckenberg (born on the 21st of August 1882 in Uetersen, Germany; died on the 19th of June 1965 in Heidelberg) was an engineer and pioneer of high speed railway systems. He designed several high speed trains. His most famous design was the Schienenzeppelin. Kruckenberg was born into an old-established Hamburg merchant family. From 1904 to 1907 he studied mechanical engineering at the Technische Hochschule Charlottenburg in Berlin, graduating in naval engineering. Before World War I he designed aircraft and airships. Even then he already criticised airships because of their explosive hydrogen filling; and the civil use of aircraft because of their high fuel- and maintenance costs. The revolutionary Schienenzeppelin After the first World War he opened an engineering consultancy in Heidelberg. Initially he worked on a hanging monorail concept, but could not get the financing for a prototype. Later together with Hermann Föttinger he founded the Flugbahn-Gesel ...

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 conjoined ...

Maintenance, Repair And Operations
The technical meaning of maintenance involves functional checks, servicing, repairing or replacing of necessary devices, equipment, machinery, building infrastructure, and supporting utilities in industrial, business, and residential installations. Over time, this has come to include multiple wordings that describe various cost-effective practices to keep equipment operational; these activities occur either before or after a failure. Definitions Maintenance functions can defined as maintenance, repair and overhaul (MRO), and MRO is also used for maintenance, repair and operations. Over time, the terminology of maintenance and MRO has begun to become standardized. The United States Department of Defense uses the following definitions:Federal Standard 1037C and from MIL-STD-188 and from the Department of Defense Dictionary of Military and Associated Terms * Any activity—such as tests, measurements, replacements, adjustments, and repairs—intended to retain or restore a fun ...

Streamliner
A streamliner is a vehicle incorporating wikt:streamline, 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 "High-speed rail, bullet trains". Less commonly, the term is applied to fully Bicycle fairing, 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 record, 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 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerodynamic
Aerodynamics, from grc, ἀήρ ''aero'' (air) + grc, δυναμική (dynamics), is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simulations has formed a rational basis for ...

Hydraulic
Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow, dam design, fluidics and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. Free surface hydraulics is the branch of hydraulics dealing with free surface flow, such as occurring in rivers, canals, lakes, estuar ...

Wittenberge
Wittenberge () is a town of eighteen thousand people on the middle Elbe in the district of Prignitz, Brandenburg, Germany. Geography Wittenberge is situated at the right (north-eastern) bank of the middle Elbe at its confluence with the Stepenitz and Karthane in the German district of Prignitz. Within the same district, the town borders the '' Ämter'' Lenzen-Elbtalaue and Bad Wilsnack/Weisen as well as the district capital Perleberg.

Ludwigslust
Ludwigslust () is a central castle town of Mecklenburg-Vorpommern, Germany, 40 km south of Schwerin. Since 2011 it has been part of the Ludwigslust-Parchim district. Ludwigslust is part of the Hamburg Metropolitan Region. The former royal residential town is known for its rich heritage, especially the famed Ludwigslust Palace, known as ''Versailles of the North''. History In 1724 Prince Ludwig, the son of Frederick, Duke of Mecklenburg, decided to build a hunting lodge near a small hamlet called Klenow. Later, after his succession to the Dukedom, this became his favourite residence and he named it accordingly ''Ludwigslust'' ("Ludwig's pleasure/desire"). In 1765 Ludwigslust became the capital of the duchy in place of Schwerin. The town was enlarged by a residential palace (the castle). This situation continued until 1837, when Grand Duke Paul Friedrich returned the capital status to Schwerin. The Wöbbelin concentration camp—sometimes referred to as ''Ludwigslust c ...
