Union County, Tennessee
Union County is a county located in the U.S. state of Tennessee. As of the 2010 census, its population was 19,109. Its county seat is Maynardville. Union County is included in the Knoxville metropolitan statistical area. History Union County was formed in 1850 from portions of Grainger, Claiborne, Campbell, Anderson, and Knox Counties. At least two theories are given on the source of its name. The name may commemorate the "union" of sections of five counties, or it may reflect East Tennessee's support for the preservation of the Union in the years before and during the Civil War. The enabling legislation was initially passed January 3, 1850, but due to legal challenges and complications, the county was not formally created until January 23, 1856. The county seat was originally named "Liberty", but renamed "Maynardville" in honor of attorney and congressman Horace Maynard, who had defended the county in a court case that sought to block its formation. In the 1930s, the dam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norfolk Navy Yard
The Norfolk Naval Shipyard, often called the Norfolk Navy Yard and abbreviated as NNSY, is a U.S. Navy facility in Portsmouth, Virginia, for building, remodeling and repairing the Navy's ships. It is the oldest and largest industrial facility that belongs to the U.S. Navy as well as the most comprehensive. Located on the Elizabeth River, the yard is just a short distance upriver from its mouth at Hampton Roads. It was established as Gosport Shipyard in 1767. Destroyed during the American Revolutionary War, it was rebuilt and became home to the first operational drydock in the United States in the 1830s. Changing hands during the American Civil War, it served the Confederate States Navy until it was again destroyed in 1862, when it was given its current name. The shipyard was again rebuilt, and has continued operation through the present day. History British control The Gosport Shipyard was founded on November 1, 1767 by Andrew Sprowle on the western shore of the Elizabeth Rive ...

Type C2 Ship
Type C2 ships were designed by the United States Maritime Commission (MARCOM) in 1937–38. They were all-purpose cargo ships with five holds, and U.S. shipyards built 328 of them from 1939 to 1945. Compared to ships built before 1939, the C2s were remarkable for their speed and fuel economy. Their design speed was , but some could make on occasion. The first C2s were long, broad, and deep, with a draft. Later ships varied somewhat in size. Some, intended for specific trade routes, were built with significant modifications in length and capacity. In 1937, MARCOM distributed tentative designs for criticism by shipbuilders, ship owners, and naval architects. The final designs incorporated many changes suggested by these constituencies. The ships were to be reasonably fast but economical cargo ships which, with some government subsidies to operators, could compete with vessels of other nations. Building costs were to be minimized by standardization of design and equipment, and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oerlikon 20 Mm Cannon
The Oerlikon 20 mm cannon is a series of autocannons, based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II. Many versions of the cannon are still used today. Blowback-operated models History Origins During World War I, the German industrialist Reinhold Becker developed a 20 mm caliber cannon, known now as the 20 mm Becker using the advanced primer ignition blowback (API blowback) method of operation. This used a 20×70mmRB cartridge and had a cyclic rate of fire of 300 rpm. It was used on a limited scale as an aircraft gun on ''Luftstreitkräfte'' warplanes, and an anti-aircraft gun towards the end of that war. Because the Treaty of Versailles banned further production of such weapons in Germany, the patents and design works were transferred in 1919 to the Swiss firm SEMAG (''Seeba ...

Bofors 40 Mm Automatic Gun L/60
The Bofors 40 mm Automatic Gun L/60 (often referred to simply as the "Bofors 40 mm gun", the "Bofors gun" and the like, see name) is an anti-aircraft autocannon, designed in the 1930s by the Swedish arms manufacturer AB Bofors. The gun was designed as an intermediate anti-aircraft gun, filling the gap between fast firing close-range small calibre anti-aircraft guns and slower firing long-range high calibre anti-aircraft guns, a role which previously was filled by older outdated guns. The Bofors 40 mm L/60 was for its time perfectly suited for this role and outperformed competing designs in the years leading up to World War II in both effectiveness and reliability. It entered the export market around 1932 and was in service with 18 countries by 1939. Throughout World War II it became one of the most popular and widespread medium-weight anti-aircraft guns. It was used by the majority of the western Allies and some Axis powers such as Nazi Germany and Hungary. In the pos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
5"/38 Caliber Gun
The Mark 12 5"/38 caliber gun was a United States dual-purpose naval gun, but also installed in single-purpose mounts on a handful of ships. The 38 caliber barrel was a mid-length compromise between the previous United States standard 5"/51 low-angle gun and 5"/25 anti-aircraft gun. United States naval gun terminology indicates the gun fired a projectile in diameter, and the barrel was 38 calibers long. The increased barrel length provided greatly improved performance in both anti-aircraft and anti-surface roles compared to the 5"/25 gun. However, except for the barrel length and the use of semi-fixed ammunition, the 5"/38 gun was derived from the 5"/25 gun. Both weapons had power ramming, which enabled rapid fire at high angles against aircraft. The 5"/38 entered service on , commissioned in 1934, the first new destroyer design since the last ''Clemson'' was built in 1922. The base ring mount, which improved the effective rate of fire, entered service on , commissioned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbine
A turbine ( or ) (from the Greek , ''tyrbē'', or Latin ''turbo'', meaning vortex) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator.Munson, Bruce Roy, T. H. Okiishi, and Wade W. Huebsch. "Turbomachines." Fundamentals of Fluid Mechanics. 6th ed. Hoboken, NJ: J. Wiley & Sons, 2009. Print. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and waterwheels. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Credit for invention of the steam turbine is given both to Anglo-Irish engineer Sir Charles Parsons (1854–1931) for invention of the reaction turbine, and to ...
