Nice, you guys pretty much answered all of my questions, thank you so much. I've been buggin 'bout those for a darn long time.
Okay ,now I got another question; same topic but different category. With regards to the simple picture I made up below (which means is may be too general).
In a ramjet's combustion chamber, the air is compressed but going subsonic in the chamber and I would assume fuel would combust with the in-coming air like any turbojet engine would at that point. What about scramjets? Their combustion process occurs entirely supersonic, so wouldn't there be shockwaves everywhere? If so, would it not interfere with the mixing of fuel? (I donno about the Hyper-X's engine specifics other than NASA being a bit jumpy w.r.t X-43's combuster.)
For example, in the pix, I drew in th red shock lines coming off the intake spike and spreading about the combustion chamber. Could anybody give me an idea as how the fuel (I assume atomized) mixes at all with such a high speed flow of air?
Thank you and good night.
