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 total i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
