Hard Mobile Launcher
The Hard Mobile Launcher (HML) is a mobile radiation-hardened truck transporter erector launcher designed to facilitate the transport and launching of the MGM-134 Midgetman missile. Overview It can travel at speeds of up to 55 mph on the road and it also has off-road capabilities. The vehicle also has a trailer mounted plow which can be used to dig the launcher into the earth in order to help protect it were it within the vicinity of a nuclear detonation. The vehicle weighs a total of 108,400 kg (239,000 pounds), with a length of over 33.5m (110 feet) and it has the capability to transport objects weighing up to 36,300 kg (80,000 pounds). It is powered by a Rolls-Royce Perkins diesel engine which produces 1200 hp and controls all 8 wheels using an electro-hydraulic transmission. Design and testing Two teams were assigned to develop a vehicle. Caterpillar developed a tracked tractor (Mobil-Trac System) while Martin Marietta was the system integrator and ...

Radiation Hardening
Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation ( particle radiation and high-energy electromagnetic radiation), especially for environments in outer space (especially beyond the low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear warfare. Most semiconductor electronic components are susceptible to radiation damage, and radiation-hardened (rad-hard) components are based on their non-hardened equivalents, with some design and manufacturing variations that reduce the susceptibility to radiation damage. Due to the extensive development and testing required to produce a radiation-tolerant design of a microelectronic chip, the technology of radiation-hardened chips tends to lag behind the most recent developments. Radiation-hardened products are typically tested to one or more resultant-effects tests, including tot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martin Marietta
The Martin Marietta Corporation was an American company founded in 1961 through the merger of Glenn L. Martin Company and American-Marietta Corporation. In 1995, it merged with Lockheed Corporation to form Lockheed Martin. History Martin Marietta formed in 1961 by the merger of the Glenn L. Martin Company and American-Marietta Corporation. Martin, based in Baltimore, was primarily an aerospace concern with a recent focus on missiles, namely its Titan program. American-Marietta was headquartered in Chicago and produced paints, dyes, metallurgical products, construction materials, and other goods. In 1982, Martin Marietta was subject to a hostile takeover bid by the Bendix Corporation, headed by William Agee. Bendix bought the majority of Martin Marietta shares and in effect owned the company. However, Martin Marietta's management used the short time separating ownership and control to sell non-core businesses and launch its own hostile takeover of Bendix (known as the Pac ...

Missile Launchers
A rocket launcher is a weapon that launches an unguided, rocket-propelled projectile. History The earliest rocket launchers documented in imperial China consisted of arrows modified by the attachment of a rocket motor to the shaft a few inches behind the arrowhead. The rocket was propelled by the burning of the black powder in the motor; these should not be confused with early fire arrows, which were conventional arrows carrying small tubes of black powder as an incendiary that ignited only after the arrow hit its target. The rocket launchers were constructed of wood, basketry, and bamboo tubes. The launchers divided the rockets with frames meant to keep them separated, and the launchers were capable of firing multiple rockets at once. Textual evidence and illustrations of various early rocket launchers are found in the 1510 edition of the ''Wujing Zongyao'' translated by Needham and others at Princeton University. (The original ''Wujing Zongyao'' was compiled between 104 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Goodyear Aerospace
Goodyear Aerospace Corporation (GAC) was the aerospace and defense subsidiary of the Goodyear Tire and Rubber Company. The company was originally operated as a division within Goodyear as the Goodyear Zeppelin Corporation, part of a joint project with Luftschiffbau Zeppelin, leading to the development of rigid airships in the United States. As part of the failing relationship between the US and Germany in the era prior to World War II, the division was spun off as Goodyear Aircraft Company in 1939. The company opened a new factory in Arizona in 1941 which produced subassemblies, including subcontracted airframe construction and the design of the Goodyear F2G Corsair and Goodyear Duck. In the post-war era, the division began to diversify and made major contributions to the development of synthetic aperture radar. In 1963 they became Goodyear Aerospace, with major product lines in radar, aircraft canopies, bulletproof glass, a number of spacecraft related products, and the unique ...

Transporter Erector Launcher
A transporter erector launcher (TEL) is a missile vehicle with an integrated tractor unit that can carry, elevate to firing position and launch one or more missiles. History Such vehicles exist for both surface-to-air missiles and surface-to-surface missiles. Early on, such missiles were launched from fixed sites and had to be loaded onto trucks for transport, making them more vulnerable to attack, since once they were spotted by the enemy they could not easily be relocated, and if they were it often took hours or even days to prepare them for launch once they reached their new site. Usually a number of TELs and TELARs are linked to one command post vehicle (CP or CPV). They may use target information from target acquisition, designation and guidance radar (TADAGR or TAR). Transporter erector launcher and radar A transporter erector launcher and radar (TELAR) is a type of TEL that also incorporates part or all of the radar system necessary for firing the surface-to-air miss ...

Electrohydraulic Manual Transmission
The automated manual transmission (AMT) is a type of transmission for motor vehicles. It is essentially a conventional manual transmission but uses automatic actuation to operate the clutch and/or shift between gears. Many early versions of these transmissions that are semi-automatic in operation, such as '' Autostick'', which automatically control only the clutch — often using various forms of clutch actuation, such as electro-mechanical, hydraulic, pneumatic, or vacuum actuationhttp://hudsonterraplane.com/tech/other/DrivemasterServiceInformation.pdf — but still require the driver's manual input and full control to initiate gear changes by hand. These systems that require manual shifting are also referred to as clutchless manual systems. Modern versions of these systems that are fully automatic in operation, such as '' Selespeed'' and '' Easytronic'', can control both the clutch operation and the gear shifts automatically, by means of an ECU, therefore requiring no ma ...
