Talk:Common Core Booster

What is "Common" used as?

Hello all. I would like to know what "common core" in the title is used as. Is it used as "shared" core or "standard" / "general" core ? Because in the picture there are two nozzles out of one booster body. Thanks in advanced. --Guyver (talk) 11:05, 6 November 2015 (UTC)

The common core booster is so named because it is the "standard" component that makes up the core of all Atlas V launch vehicles. The Atlas V design is modular and the common core booster can have solid rocket boosters (or even more common cores) attached to it depending on the configuration. The booster has two nozzles because the RD-180 is a single engine that has two combustion chambers. 146.126.51.51 (talk) 20:03, 26 March 2018 (UTC)

Construction - structure

The tanks walls are made from 4 curved isogrid aluminum alloy panels friction stir welded length ways (like a banana peel) - per barrel (2 barrels for LOX, 1 for RP). [1] Tank domes are spun formed. - ... Atlas V user guide p375 says it uses Aluminium alloy 2014. - Rod57 (talk) 20:17, 17 August 2021 (UTC)
