It seems so much different than what I am used to seeing. I was thinking that it was probably red fuming nitric acid for the oxidiser and something like hydrazine for the fuel. American Titan rockets used the same mix, or white fuming nitric acid instead, 'cause it's hypergolic (the two items ignite on contact) and so doesn't need specialised ignition systems, and the storage requirements are much lower than that required for LOX/LH or LOX/JP4. http://en.wikipedia.org/wiki/Titan_(rocket_family) Here's a pic of a Titan lifting, using white fuming nitric as the oxidiser: http://en.wikipedia.org/wiki/File:Last_Titan_Rocket-Vanderburg_AFB.jpg Of course, it's _nitric acid_ and _hydrazine_, so staying upwind is a Really Good Idea. |
