Is their a fuel that can be used for rocket fuel and ramjet fuel?

[KDOG]

ALso, do you know where I can find out how a ramjet/scramjet engine is shaped?

 

[HombrePequeno]

I know most rockets use either methane, kerosene, or hydrogen mixed with o2. I don't really know what sc/ramjets use though. I'll do a search for it.

Edit: Here's a good site on ramjets: Ramjet and its kin

Just refine and refine and refine....

you mean liquid fuel rockets? those are a pain, solid fuel is a lot easier to make...
