German Empire
The German Empire (), Herbert Tuttle wrote in September 1881 that the term "Reich" does not literally connote an empire as has been commonly assumed by English-speaking people. The term literally denotes an empire – particularly a hereditary empire led by an emperor, although has been used in German to denote the Roman Empire because it had a weak hereditary tradition. In the case of the German Empire, the official name was , which is properly translated as "German Empire" because the official position of head of state in the constitution of the German Empire was officially a " presidency" of a confederation of German states led by the King of Prussia who would assume "the title of German Emperor" as referring to the German people, but was not emperor of Germany as in an emperor of a state. –The German Empire" ''Harper's New Monthly Magazine''. vol. 63, issue 376, pp. 591–603; here p. 593. also referred to as Imperial Germany, the Second Reich, as well as simply Germa ...

Ceremonial Ship Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow (ship), bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widel ...

Varna, Bulgaria
Varna ( bg, Варна, ) is the third-largest city in Bulgaria and the largest city and seaside resort on the Bulgarian Black Sea Coast and in the Northern Bulgaria region. Situated strategically in the Gulf of Varna, the city has been a major economic, social and cultural centre for almost three millennia. Historically known as ''Odessos'' ( grc, Ὀδησσός), Varna developed from a Thracian seaside settlement to a major seaport on the Black Sea. Varna is an important centre for business, transportation, education, tourism, entertainment and healthcare. The city is referred to as the maritime capital of Bulgaria and has the headquarters of the Bulgarian Navy and merchant marine. In 2008, Varna was designated as the seat of the Black Sea Euroregion by the Council of Europe. In 2014, Varna was awarded the title of European Youth Capital 2017.

NMS Smeul
NMS ''Smeul'' was a torpedo boat of the Royal Romanian Navy. She was commissioned in 1920, after initially serving as ''Tb 83 F'' in the Austro-Hungarian Navy during World War I. She and six more sister ships were awarded to Romania as reparations after the war ended. Construction and specifications A vessel of the F-group of the 250t-class, ''Smeul'' was built by Ganz & Danubius at Fiume and nearby Porto Re, along with the rest of her group, between October 1913 and December 1916. Under the designation ''83 F'', she was laid down in 1913, launched in 1914 and completed in 1915. She had a waterline length of , a beam of , and a normal draught of . While her designed displacement was , she displaced about fully loaded. The crew consisted of 38 officers and enlisted men. Her AEG-Curtiss turbines were rated at with a maximum output of , enabling her to reach a top speed of . She carried of coal and of fuel oil, which gave her a range of at .

Sulina
Sulina () is a town and free port in Tulcea County, Northern Dobruja, Romania, at the mouth of the Sulina branch of the Danube. It is the easternmost point of Romania. History During the mid-Byzantine period, Sulina was a small cove, and in the 14th century, a Genoese port inhabited by a handful of sailors, pirates and fishermen. In the 18th century, the Ottomans built a lighthouse there in order to facilitate communication between Constantinople (Istanbul) and the Danubian Principalities, the main breadbaskets for the Ottoman capital. Thanks to the signing of the Treaty of Adrianoupolis (Edirne) on September 2, 1829, that unfettered the Danube grain trade, Sulina, by then under Russian control, became an important port. Great sailing boats could not sail fully loaded to Brăila and Galați, which were the main export centres of Wallachia and Moldavia, because of the shallow waters of the river; therefore, they had to tranship at least part of their cargoes to smaller riv ...

Constantinople Flotilla
The Constantinople Flotilla (german: U-Flottille Konstantinopel) was an Imperial German Navy formation set up during World War I to prosecute the U-boat campaign against Allied shipping in the Mediterranean and the Black Sea in support of Germany's ally, the Ottoman Empire. Despite its official name, the "U-boats of the Mediterranean Division in Constantinople" (''U-Boote der Mittelmeerdivision in Konstantinopel''), it saw little service there, operating mostly against Russian shipping in the Black Sea. The Constantinople Flotilla had a maximum strength of 11 U–boats but due to the unfavorable conditions for commerce raiding in the Black Sea saw little success during its three years of operations. In three years of operation, the force sank ships totaling 117,093 GRT. 15 U-boats served in the Constantinople Flotilla; 7 were lost operationally: 5 in the Black Sea and 2 in the Mediterranean. One U-boat was sold to Bulgaria. Two more U-boats were assigned to the Flotilla but we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propeller Shaft
A drive shaft, driveshaft, driving shaft, tailshaft (Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power and torque and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, while avoiding too much additional weight as that would in turn increase their inertia. To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings, or rag joints, and sometimes a splined joint or prismatic joint. History The term ''driveshaft'' first appeared during the mid-19th centu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benz Söhne
Carl Friedrich Benz (; 25 November 1844 – 4 April 1929), sometimes also Karl Friedrich Benz, was a German engine designer and automotive engineer. His Benz Patent Motorcar from 1885 is considered the first practical modern automobile and first car put into series production. He received a patent for the motorcar in 1886. His company Benz & Cie., based in Mannheim, was the world's first automobile plant and largest of its day. In 1926 it merged with Daimler Motoren Gesellschaft to form Daimler-Benz which produces the Mercedes-Benz among other brands. Benz is widely regarded as "the father of the car" and "father of the automobile industry". Early life Carl Benz was born Karl Friedrich Michael Vaillant, on 25 November 1844 in Mühlburg, now a borough of Karlsruhe, Baden-Württemberg, which is part of modern Germany. His parents were Josephine Vaillant and a locomotive driver, Johann Georg Benz, whom she married a few months later. According to German law, the child acquir ...

Draught (ship)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam (ship)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a co ...
