Atlas was a liquid propellant rocket burning RP-1 kerosene fuel with liquid oxygen in three engines configured in an unusual "stage-and-a-half" or "parallel staging" design: two outboard booster engines were jettisoned along with supporting structures during ascent, while the center sustainer engine, propellant tanks and other structural ...

The 1-1/2 Stage USSRC NASA Atlas. The boat tail and outboard booster engines are jettisoned after the initial boost phase, leaving the sustainer and verniers to run for the remainder of the boost. Rocketdyne introduced five key innovations when developing the Navaho Phase II and III propulsion systems, which led to Atlas/Jupiter/Thor propulsion.
Jan 1, 2021 · Atlas missiles used five Rocketdyne engines; two LR89 boosters, a single LR105 sustainer engine, and two LR101 vernier engines that provided roll control and fine targeting. Bossart realized that much of the risk in multi-stage liquid-fuel rockets involved starting the upper-stage engines in flight, and employed an innovative approach to ...
Aug 21, 2002 · The one-engine Centaur can produce a thrust of 22,290 pounds. The two-engine Centaur can produce a thrust of 41,592 pounds. There are a number of variants of the Atlas V, based upon the size of the payload fairing, the number of solid rocket boosters and the second stage Centaur configuration.

Atlas V [a] is an expendable launch system and the fifth major version in the Atlas launch vehicle family. It was originally designed by Lockheed Martin, now being operated by United Launch Alliance (ULA), a joint venture between Lockheed Martin and Boeing. It is used for DoD, NASA, and Commercial payloads.

4 days ago · The Atlas III, introduced in 2000, was the last to use the “stage and a half” design. It also used in its first stage a Russian-produced rocket engine, the RD-180, the design of which was based on the RD-170 developed for the Soviet Energia and Zenit launch vehicles.
The Atlas V booster uses the RD-180 engine first used on the Atlas III. The rocket family features a stretched Centaur stage (right) allowing increased performance over previous versions. The new Centaur second stage can have either one or two RL-10A-4-2 rocket engines, allowing performance to better match payload.
