Talk:YF-50t

I believe that this engine doesn't exists or it is the YF-75D.
I've been reading a Chinese presentation at the IAC 2013 regarding the history of hydrogen/oxygen rocket engines in China and I have found no mention of the YF-50t. Neither did I found it in any modern Long March 5 specification. The YF-75D is a closed cycle engine (albeit an expander) and is going to power the second stage of the Long March 5. So, may be the YF-50t was a project but the trades ended up with the YF-75D? I couldn't find any reference besides the Encyclopedia Astronautica article, which seems unsourced. — Preceding unsigned comment added by Baldusi (talk • contribs) 2015-07-09T00:36:08
