Atlas IIIA. Atlas V. Atlas is a family of US missiles and space launch vehicles that originated with the SM-65 Atlas. The Atlas intercontinental ballistic missile (ICBM) program was initiated in the late 1950s under the Convair Division of General Dynamics. [2] Atlas was a liquid propellant rocket burning RP-1 kerosene fuel with liquid oxygen ...
Jan 1, 2021 · The two booster engines shared a turbopump and gas generator. The verniers received propellants from the sustainer. This configuration was used on Atlas B and C test missiles. MA-2, produced from 1958 through 1962, consisted of two XLR89-5 booster engines, an LR105-5 sustainer, and two LR101 vernier engines. The two booster engines each had its ...

Rocketdyne objected, because JP-4 production and purity standards were too loose to permit its use as a rocket fuel. Finally, a highly-refined version of JP-4 known as RP-1 (Rocket Propellant 1) was developed. LOX was retained as the oxidizer. This combination became the basis for a number of rocket engines.
The vernier engines, a trademark of Atlas vehicles, were designed to control the roll of the missile and trim its final flight velocity. The booster and vernier engines were all fed by liquid oxygen/RP-1 (kerosene) liquid propellant, and all engines were ignited at liftoff.
use of an Atlas 541 indicated that the satellite would likely be heavier than any previously launched by the U.S. to a Molniya orbit. A previous launch of a "Trumpet"-type sigint to 1,120 x 37,600 km x 63.56 deg Molniya orbit used a less-capable Atlas 5-411 with only one strap-on solid motor. The AV-051 Atlas was the first equipped with an RL10C-1

May 7, 2024 · The Atlas-Centaur rocket combined an Atlas first stage, which burned kerosene fuel, with a Centaur second stage, fueled with liquid hydrogen; it was the first rocket to use liquid hydrogen as fuel. Further versions of the Atlas included the SLV-3, a standardized launch vehicle designed for both military and civilian use that operated in various ...
Feb 13, 2006 · Scientists measure the efficiency of rocket propellants by what is termed vehicle specific impulse. This measures the impulse, or change in momentum, per unit of propellant expended.
