T2 Tanker
The T2 tanker, or T2, was a class of oil tanker constructed and produced in large numbers 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 Petroleum, black oil-crude oil. After the war, many T2s remained in use, and as with other hastily-built World War II ships later converted to peacetime uses, there were safety concerns. The United States Coast Guard Marine Board of Investigation in 1952 found that in cold weather the ships were prone to metal fatigue (material), fatigue cracking; in response to this finding, surviving ships 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 2016 film ''The Finest Hours (2016 film), The Finest Hours''.

Mobil
Mobil Oil Corporation, now known as just Mobil, is a petroleum brand owned and operated by American oil and gas corporation ExxonMobil, formerly known as Exxon, which took its current name after history of ExxonMobil#merger, it and Mobil merged in 1999. A direct descendant of Standard Oil, Mobil was originally known as the Standard Oil Company of New York (shortened to Socony) after Standard Oil was Standard Oil Co. of New Jersey v. United States, split into 43 different entities in a 1911 Supreme Court decision. Socony merged with Vacuum Oil Company, from which the Mobil name first originated, in 1931 and subsequently renamed itself to "Socony-Vacuum Oil Company". Over time, Mobil became the company's primary identity, which prompted a renaming in 1955 to the "Socony Mobil Oil Company", and then in 1966 to the "Mobil Oil Corporation". Mobil credits itself with being the first company to introduce Pay at the pump, paying at the pump at its gas stations, the first company to pro ...

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 ... [...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 f ...

Standard Oil Company
Standard Oil Company was a corporate trust in the petroleum industry that existed from 1882 to 1911. The origins of the trust lay in the operations of the Standard Oil Company (Ohio), which had been founded in 1870 by John D. Rockefeller. The trust was born on January 2, 1882, when a group of 41 investors signed the Standard Oil Trust Agreement, which pooled their securities of 40 companies into a single holding agency managed by nine trustees. The original trust was valued at $70 million. On March 21, 1892, the Standard Oil Trust was dissolved and its holdings were reorganized into 20 independent companies that formed an unofficial union referred to as "Standard Oil Interests." In 1899, the Standard Oil Company (New Jersey) acquired the shares of the other 19 companies and became the holding company for the trust. Jersey Standard operated a near monopoly in the American oil industry from 1899 until 1911 and was the largest corporation in the United States. In 1911, the landma ...

Sun Shipbuilding & Drydock
Sun Shipbuilding & Drydock Company (1917–1982) was a major shipbuilding company in Chester, Pennsylvania on the Delaware River. Its primary product was tankers, but the company built many types of ships over its 70-year history. During World War II, it participated in the U.S. Government's Emergency Shipbuilding Program. The company was also part of the U.S. aerospace industry during the Cold War; it built various propulsion research & development structures, including the largest U.S. rocket test chamber, for Aerojet General in 1963. History The company was developed by Sun Oil Company, and launched its first ship in 1917, just as the United States was entering World War I. Under the direction of its president, John Glenn Pew, the company experienced tremendous success over the following decades. In the 1920s, it had become a large shipyard that built tankers for the Standard Oil Company. In 1936, the Pew family offered John J. McClure and his Republican political machi ...

Propeller (marine)
A propeller (often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from stern sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the water at the effective angl ...
