We've been completely lobsided towards P&WR content - naturally, due to the SSMEs and such - so I'm balancing it out with news from the nice folk at Aerojet, which is time sensitive as they announced this today.

Got about 10 (not even joking) SLS articles in line for December, so while we've gone a bit EELV crazy of late, it'll all balance out too ;D

Great article Chris!  From the AJ-26 on Taurus II to the booster engine on SLS and now this new upperstage engine, Aerojet seems to be aggressively pursuing new engine contracts and thirsty for more!  This will be good for ULA, Boeing, NASA and the DoD as EELV's and potentially SLS get some much needed competition from suppliers.

As usual - great article. When do we see the specs on the engine; isp T/W etc.

Thanks! And oh yeah, I might add a line about the AJ-26. Not sure about the specs release - I'm guessing there's a lot of prop info right now.

And thanks to Pippin and Proponent on the Saturn catch :)

Chris maybe Aerojet can give some details for L2 of the AJ-26-500 ?

or for that matter, any presentations form Aerojet on the AJ-26 being utilized for Taurus II, I know someone who would find that useful  ;D

Lovely! I would really like you to have a nice, technical talk on Us engines (European, too). Can't you get an article on the Vinci, for example? Or Engilish and Germans still don't talk? :p

I wonder how it will compare to the RL-60. The EELVs have really late and fast staging points. They'd be better using a heavier upper stage with more prop and thrust, so they can get onto the more efficient vacuum engine at a lower velocity.

It's hard to argue with the logic of sizing an upper stage engine based on the answer to the question: "well, how much thrust can we get out of the expander cycle?" Because then you get a high-performance engine with relatively low cost, complexity, and mass.

Cf. http://forum.nasaspaceflight.com/index.php?topic=23029.0

Highest-grade ore for public domain development engine information is to search for papers at the AIAA web site.
If I like something on NSF, it's probably because I know it to be accurate.  Every once in a while, it's just something I agree with.  Facts generally receive the former.
