T2 Tanker
The T2 tanker, or T2, was a class of oil tanker constructed and produced in large quantities in the United States during World War II. Only the T3 tankers were larger "navy oilers" of the period. Some 533 T2s were built between 1940 and the end of 1945. They were used to transport fuel oil, diesel fuel, gasoline and sometimes black oil-crude oil. Post war many T2s remained in use; like other hastily built World War II ships pressed into peacetime service, there were safety concerns. As was found during the war, the United States Coast Guard Marine Board of Investigation in 1952 stated that in cold weather the ships were prone to metal fatigue cracking, so were "belted" with steel straps. This occurred after two T2s, and , split in two off Cape Cod within hours of each other. ''Pendleton''s sinking is memorialized in '' The Finest Hours''. Engineering inquiries into the problem suggested the cause was poor welding techniques. It was found the steel (that had been successfully use ...

Alabama Drydock And Shipbuilding Company
The Alabama Drydock and Shipbuilding Company (ADDSCO) located in Mobile, Alabama, was one of the largest marine production facilities in the United States of America during the 20th century. It began operation in 1917, and expanded dramatically during World War II; with 30,000 workers, including numerous African Americans and women, it became the largest employer in the southern part of the state. During the defense buildup, which included other shipyards, Mobile became the second-largest city in the state, after Birmingham. Shipbuilding declined in the United States in the later 20th century, and ADDSCO closed its yard in the mid-1970s. It later re-opened. ADDSCO is now owned by BAE Systems, which purchased the yard from Atlantic Marine in May 2010. World War II During and after World War II, ADDSCO became the largest employer in southern Alabama, building Liberty ships, tankers and other vessels from the keel up, often at rapid speeds during the stateside war effort.

Range (vehicle)
The maximal total range is the maximum distance an aircraft can fly between takeoff and landing. Powered aircraft range is limited by the aviation fuel energy storage capacity (chemical or electrical) considering both weight and volume limits. Unpowered aircraft range depends on factors such as cross-country speed and environmental conditions. The range can be seen as the cross-country ground speed multiplied by the maximum time in the air. The fuel time limit for powered aircraft is fixed by the available fuel (considering reserve fuel requirements) and rate of consumption. Some aircraft can gain energy while airborne through the environment (e.g. collecting solar energy or through rising air currents from mechanical or thermal lifting) or from in-flight refueling. These aircraft could theoretically have an infinite range. Ferry range means the maximum range that an aircraft engaged in ferry flying can achieve. This usually means maximum fuel load, optionally with extra fuel tan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thrust
Thrust is a reaction force described quantitatively by Newton's third law. When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction to be applied to that system. The force applied on a surface in a direction perpendicular or normal to the surface is also called thrust. Force, and thus thrust, is measured using the International System of Units (SI) in newtons (symbol: N), and represents the amount needed to accelerate 1 kilogram of mass at the rate of 1 meter per second per second. In mechanical engineering, force orthogonal to the main load (such as in parallel helical gears) is referred to as static thrust. Examples A fixed-wing aircraft propulsion system generates forward thrust when air is pushed in the direction opposite to flight. This can be done by different means such as the spinning blades of a propeller, the propelling jet of a jet engine, or by ejecting hot gases from a rocket ...

Turbo-electric Transmission
A turbo-electric transmission uses electric generators to convert the mechanical energy of a turbine (steam or gas) into electric energy, which then powers electric motors and converts back into mechanical energy that power the driveshafts. Turbo-electric drives are used in some rail locomotives (gas turbines, ''e.g.'' with the first TGV) and ships (steam and more recently gas turbines). An advantage of turbo-electric transmission is that it allows the adaptation of high-speed turbines to slow turning propellers or wheels without a heavy and complex gearbox. It has the advantage of being able to provide electricity for the ship or train's other electrical systems, such as lighting, computers, radar, and communications equipment. Other advantages for ships include greater watertight subdivision, quieter operations, and safety (via instant thrust reversal by changing engine direct current polarity) for submarines.Friedman, 1994, pp 136, 147–149 Ships with turbo-electric drive ...

Standard Oil Company
Standard Oil Company, Inc., was an American oil production, transportation, refining, and marketing company that operated from 1870 to 1911. At its height, Standard Oil was the largest petroleum company in the world, and its success made its co-founder and chairman, John D. Rockefeller, who is among the wealthiest Americans of all time and among the richest people in modern history. Its history as one of the world's first and largest multinational corporations ended in 1911, when the U.S. Supreme Court ruled that it was an illegal monopoly. The company was founded in 1863 by Rockefeller and Henry Flagler, and was incorporated in 1870. Standard Oil dominated the oil products market initially through horizontal integration in the refining sector, then, in later years vertical integration; the company was an innovator in the development of the business trust. The Standard Oil trust streamlined production and logistics, lowered costs, and undercut competitors. "Trust-busting" cri ...

Attack On Pearl Harbor
The attack on Pearl HarborAlso known as the Battle of Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service upon the United States against the naval base at Pearl Harbor in Honolulu, Territory of Hawaii, just before 8:00a.m. (local time) on Sunday, December 7, 1941. The United States was a neutral country at the time; the attack led to its formal entry into World War II the next day. The Japanese military leadership referred to the attack as the Hawaii Operation and Operation AI, and as Operation Z during its planning. Japan intended the attack as a preventive action. Its aim was to prevent the United States Pacific Fleet from interfering with its planned military actions in Southeast Asia against overseas territories of the United Kingdom, the Netherlands, and those of the United States. Over the course of seven hours there were coordinated Japanese attacks on the US-held Philippines, Guam, and Wake Island and on the British Empire ...

Maryland
Maryland ( ) is a state in the Mid-Atlantic region of the United States. It shares borders with Virginia, West Virginia, and the District of Columbia to its south and west; Pennsylvania to its north; and Delaware and the Atlantic Ocean to its east. Baltimore is the largest city in the state, and the capital is Annapolis. Among its occasional nicknames are '' Old Line State'', the ''Free State'', and the '' Chesapeake Bay State''. It is named after Henrietta Maria, the French-born queen of England, Scotland, and Ireland, who was known then in England as Mary. Before its coastline was explored by Europeans in the 16th century, Maryland was inhabited by several groups of Native Americans – mostly by Algonquian peoples and, to a lesser degree, Iroquoian and Siouan. As one of the original Thirteen Colonies of England, Maryland was founded by George Calvert, 1st Baron Baltimore, a Catholic convert"George Calvert and Cecilius Calvert, Barons Baltimore" William Hand Browne, ...
