Abbreviated Test Language for All Systems (ATLAS) is a specialized programming language for use with automatic test equipment (ATE). It is a compiled high-level computer language and can be used on any computer whose supporting software can translate it into the appropriate low-level instructions .
The Operational Silo Test Facility (OSTF) is a former United States Air Force intercontinental ballistic missile launch facility at Vandenberg Space Force Base, California, United States. It was a developmental launch site for the silo-based Titan and Atlas missile series. [1] The site was originally constructed for Titan I tests. On 12 ...
Atlas, test number 449, Air Force Missile Test Center. The Convair X-11 / SM-65A Atlas / Atlas A was the first full-scale prototype of the Atlas missile, first flying on 11 June 1957. [ 21 ] It was a test model designed to verify the structure and propulsion system, and had no sustainer engine or separable stages.
The B series test program took a considerable amount of delays and frustration, not in the least because the Atlas B was far more complicated than the prototype Atlas A, in fact the first launch would feature all hardware systems found on an operational Atlas, including the sustainer engine, separable booster section, guidance computer, Azusa tracking system, detachable nose cone, and more.
The fully operational D-series Atlas was similar to the R&D model Atlas B and C, but incorporated a number of design changes implemented as a result of lessons learned during test flights. In addition, the D-series had the full-up Rocketdyne MA-2 propulsion system with 360,000 pounds-force (1,600 kN) of thrust versus the 250,000 pounds-force ...
The first successful test launch of an SM-65 Atlas missile was on 17 December 1957. [1] Approximately 350 Atlas missiles were built. [4] The Atlas boosters would collapse under their own weight if not kept pressurized with nitrogen gas in the tanks when devoid of propellants. The Atlas booster was unusual in its use of "balloon" tanks.
