Revere Copper And Brass
The Revere Copper Company is a copper rolling mill in the United States. It operated North America's first copper rolling mill. It was started by Paul Revere in 1801 in Canton, Massachusetts, and developed a commercially viable process for manufacturing copper sheets. History Copper rolling process Copper rolling is the process of converting large blocks of copper into thin sheets by rolling them gradually down to size. These sheets of copper were used in the 18th and 19th centuries mainly to plate the bottoms of ships. This process of plating ship bottoms, referred to as “sheathing” or “coppering”, helped increase the speed and lifespan of ships. Copper was desired for this process because it reacts with seawater to create an oxide coating that prevents the build-up of barnacles, weeds, and other detritus, in addition to physically stopping shipworm, shipworms from burrowing into and degrading the wood.

Unguided Rocket
In military terminology, a rocket is a self-propelled, generally unguided, weapon-system powered by a rocket engine. Though used primarily as medium- and long-range artillery systems, historically rockets have also seen considerable use as air-to-surface weapons, some use as air-to-air weapons, and even (in a few cases) as surface-to-air devices. Examples of modern surface-to-surface rocket systems include the Soviet BM-27 Uragan and the American M270 Multiple Launch Rocket System. In military parlance, a rocket differs from a missile primarily by lacking an active guidance system; early missiles became known as "guided rockets" or "guided missiles". Some rockets were developed as unguided systems and later upgraded to guided versions, like the GMLRS, and these generally retain the term "rocket" instead of becoming "missiles". Rockets or missiles that travel underwater, like the VA-111 Shkval, are known as "torpedoes", whatever their propulsion system. Early development The ...

United States Air Force
The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control. The United States Air Force is a military service branch organized within the Department of the Air Force, one of the three military departments of the Department of Defense. The Air Force through the Department of the Air Force is headed by the civilian Secretary of the Air Force ...

Tracor
Tracor was a major North American defense electronics contractor which was acquired by Marconi Electronic Systems (MES), a subsidiary of General Electric Company plc, in 1998. Following the purchase of MES by British Aerospace in November 1999 to form BAE Systems, Tracor became BAE Systems Integrated Defense Solutions. Following a 2005 reorganisation, the company became BAE Systems Sensor Integration, part of Electronics and Integrated Solutions. History Tracor was founded in 1954 as Associated Consultants and Engineers. Tracor was the brainchild of physicist Richard N. Lane, its first president. He recruited Frank W. McBee, Dr. Chester McKinney, and Jess Stanbrough as its founders, and these four added an attorney friend, Harry Pollard, and machinist Byron Grisham, Jr. Early contracts included sales to Union Carbide and the United States Navy. The company's early focus on research and development soon expanded to the manufacture of instruments and components. In 1960 the compan ...

Electronic Countermeasures
An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile terminal homers. History The first example of electronic countermeasures being applied in a combat situation took place during ...

Rocket
A rocket (from it, rocchetto, , bobbin/spool) is a vehicle that uses jet propulsion to accelerate without using the surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. Signific ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Chaff (countermeasure)
Chaff, originally called Window by the British and ''Düppel'' by the Second World War era German Luftwaffe (from the Berlin suburb where it was first developed), is a radar countermeasure in which aircraft or other targets spread a cloud of small, thin pieces of aluminium, metallized glass fibre or plastic, which either appears as a cluster of primary targets on radar screens or swamps the screen with multiple returns, in order to confuse and distract. Modern armed forces use chaff (in naval applications, for instance, using short-range SRBOC rockets) to distract radar-guided missiles from their targets. Most military aircraft and warships have chaff dispensing systems for self-defense. An intercontinental ballistic missile may release in its midcourse phase several independent warheads as well as penetration aids such as decoy balloons and chaff. Modern radar systems can distinguish chaff from target objects by measuring the Doppler shift; chaff quickly loses speed compared ...

Cold War Rockets Of The United States
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...
