GTR-18 Smokey Sam
The GTR-18A, commonly known as the Smokey Sam, is a small unguided rocket developed by Naval Air Warfare Center Weapons Division (NAWCWD) in China Lake, California as a threat simulator for use during military exercises. Widely used in training, the Smokey Sam remains in operational service with the United States military. Design and development The GTR-18 was conceived in the late 1970s by Robert A. McLellan, a Weapons Range Scientist working with Exercise Red Flag at Nellis Air Force Base. He first searched for a commercially available system that would perform as he envisioned. It quickly became apparent that no commercial product would perform adequately, so the development of the GTR-18 was undertaken by the Naval Weapons Center (NWC) during the early 1980s, with the intent of developing Mr. McLellan's idea of a simple and inexpensive rocket for visually simulating the launch of surface-to-air missiles (SAMs) during training exercises.Parsch 2002 The design of the GTR-18A r ...

United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americ ...

Phenolic Paper
Phenolic paper is a material often used to make printed circuit board substrates (the flat board to which the components and traces are attached). It is a very tough board made of wood fibre and phenolic polymers. It is most commonly brown in colour, and is a fibre reinforced plastic. These PCB materials are known as FR-1 and FR-2 FR-2 (Flame Resistant 2) is a NEMA designation for synthetic resin bonded paper, a composite material made of paper impregnated with a plasticized phenol formaldehyde resin, used in the manufacture of printed circuit boards. Its main properties ar ... – FR-2 is rated to 130°C, FR-1 is rated to 105°C. By R.G.

Rocket Weapons Of The United States
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. Significant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface-to-air Missiles Of The United States
A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground to destroy aircraft or other missiles. It is one type of anti-aircraft system; in modern armed forces, missiles have replaced most other forms of dedicated anti-aircraft weapons, with anti-aircraft guns pushed into specialized roles. The first attempt at SAM development took place during World War II, but no operational systems were introduced. Further development in the 1940s and 1950s led to operational systems being introduced by most major forces during the second half of the 1950s. Smaller systems, suitable for close-range work, evolved through the 1960s and 1970s, to modern systems that are man-portable. Shipborne systems followed the evolution of land-based models, starting with long-range weapons and steadily evolving toward smaller designs to provide a layered defence.

Model Rocket
A model rocket are small rockets designed to reach low altitudes (e.g., for model) and be recovered by a variety of means. According to the United States National Association of Rocketry (NAR) Safety Code, model rockets are constructed of paper, wood, plastic and other lightweight materials. The code also provides guidelines for motor use, launch site selection, launch methods, launcher placement, recovery system design and deployment and more. Since the early 1960s, a copy of the Model Rocket Safety Code has been provided with most model rocket kits and motors. Despite its inherent association with extremely flammable substances and objects with a pointed tip traveling at high speeds, model rocketry historically has proven to be a very safe hobby and has been credited as a significant source of inspiration for children who eventually become scientists and engineers. History of model rocketry While there were many small rockets produced after years of research and experime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Styrofoam
Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam (XPS), commonly called "Blue Board", manufactured as foam continuous building insulation board used in walls, roofs, and foundations as thermal insulation and water barrier. This material is light blue in color and is owned and manufactured by DuPont DuPont de Nemours, Inc., commonly shortened to DuPont, is an American multinational chemical company first formed in 1802 by French-American chemist and industrialist Éleuthère Irénée du Pont de Nemours. The company played a major role in .... DuPont also has produced a line of green and white foam shapes for use in crafts and floral arrangements. ''Styrofoam'' is colloquially used worldwide to refer to another material that is usually white in color and made of expanded (not extruded) polystyrene foam ( EPS). It is often used in food containers, coffee cups, and as cushioning material in packaging. The Generic trademark, trademarked term is used g ...

Nellis Air Force Base
Nellis Air Force Base ("Nellis" colloq.) is a United States Air Force installation in southern Nevada. Nellis hosts air combat exercises such as Exercise Red Flag and close air support exercises such as Green Flag-West flown in " Military Operations Area (MOA) airspace", associated with the nearby Nevada Test and Training Range (NTTR). The base also has the Combined Air and Space Operations Center-Nellis. History After World War I, Nevada and other western inland states were surveyed by Capt. Lowell H. Smith and Sgt. William B. Whitefield for landing sites, and by "mid-1925 the Air Service possessed information on nearly thirty-five hundred landing places, including more than twenty-eight hundred emergency landing areas, in the United States." The 1929 airfield (dirt runway, water well, and small operations shack) north of Las Vegas—operated by the 1925 Western Air Express for Contract Air Mail (CAM) Route #4, Los Angeles, LA-to-Salt Lake City, SLC—was used by the ...

Exercise Red Flag
Exercise Red Flag (also Red Flag – Nellis) is a two-week advanced aerial combat training exercise held several times a year by the United States Air Force. It aims to offer realistic air-combat training for military pilots and other flight crew members from the United States and allied countries. Each year, four to six Red Flag exercises are held at Nellis Air Force Base, Nevada, while up to four more, dubbed Red Flag – Alaska, are held at Eielson Air Force Base, Alaska. First held on 29 November 1975, Red Flag exercises bring together aircrews from the United States Air Force (USAF), United States Navy (USN), United States Marine Corps (USMC), United States Army (USA) and numerous NATO and allied nations' air forces. Red Flag exercises are conducted under the control of the United States Air Force Warfare Center (USAFWC) at Nellis. They are run by the 414th Combat Training Squadron (414 CTS) of the 57th Wing (57 WG). They use "enemy" hardware and live ammunition for b ...
