Wilhelm Swarovski, son of the original founder, was born in 1918. In 1935, with the help of his father, he developed a prism fabrication and grinding process that he used in the design of his first 6×30 binocular. [2] In 1949 he founded SWAROVSKI OPTIK KG in Absam, Tyrol, to produce the Habicht 7×42 that it continues producing today.
EN 1063, or CEN 1063, is a security glazing standard created by the European Committee for Standardization for measuring the protective strength of bullet-resistant glass.
AN/GSG-10 TACFIRE. The Battery Computer System (BCS) AN/GYK-29 was a computer used by the United States Army for computing artillery fire mission data. It replaced the FADAC and was small enough to fit into the HMMWV combat vehicle. The AN/GSG-10 TACFIRE (Tactical Fire) direction system automated field artillery command and control functions. [8]
Intercept: Most systems can be used in different phases of ballistic missile flight, i.e., boost [73] (where surface or air-launched anti-aircraft missiles might also be effective because the ballistic missile is moving relatively slowly at low altitude), requiring proximity to the launch site and immediate response, mid-course/exo-atmospheric ...
The ballistic coefficient of an atmospheric reentry vehicle has a significant effect on its behavior. A very high ballistic coefficient vehicle would lose velocity very slowly and would impact the Earth's surface at higher speeds. In contrast, a low ballistic coefficient vehicle would reach subsonic speeds before reaching the ground. [75]
That is, if CEP is n metres, 50% of shots land within n metres of the mean impact, 43.7% between n and 2n, and 6.1% between 2n and 3n metres, and the proportion of shots that land farther than three times the CEP from the mean is only 0.2%. CEP is not a good measure of accuracy when this distribution behavior is not met.
The advantage of the ballistic parachute over a conventional parachute is that it ejects the parachute canopy (oftentimes via a small rocket), causing it to open rapidly, thus making it ideal for attaching to light aircraft, hang gliders and microlights, where an emergency may occur in close proximity to the ground. In such a situation, a ...
Photo series showing a Cirrus SR20 deploying the Cirrus Airframe Parachute System (CAPS) during inflight testing in 1998. The Cirrus Airframe Parachute System (CAPS) is a whole-plane ballistic parachute recovery system designed specifically for Cirrus Aircraft's line of general aviation light aircraft including the SR20, SR22 and SF50.
