Talk:Expander cycle

Citation needed for RL60 reference
http://www.spaceref.com/news/viewpr.html?pid=11883 refers to the RL60 using the expander cycle. If I can figure out how to make a footnote, I will do it. I hope someone will start a wikipedia article for the RL60, too. —Preceding unsigned comment added by 131.252.217.51 (talk) 13:03, 9 November 2008 (UTC)

DC-X as SSTO
I corrected the DC-X reference, as that vehicle was not intended to be more then a Demonstrator for key Single Stage To Orbit Technologies. --Patbahn (talk) 20:13, 27 January 2011 (UTC)

Square-cube law
A better explanation of the square-cube law would be desirable. It's hard to see why fuel consumption would increase with the cube of nozzle diameter when the injector plate area increases only with the square and is proportional to the total nozzle area.Danwoodard (talk) 02:49, 1 April 2013 (UTC)

figures
In the figures Heat Exanger should be Heat Exchanger. Also note that the numbers in the table for the RL-10 are for an early version; current versions (RL-10B-2 & RL-10C-1) are quite different. 69.72.92.195 (talk) 22:32, 25 April 2017 (UTC)
