Speaking of rocket fuel (re: onion atricle), can anyone hazard a guess at the propellant used in katyusha rockets? The reason I ask is because it seems like it is a fairly long burning engine with "moderate"* levels of thrust - just what one would want for a rocket glider. Of course core design has something to do with performance to. These seem like awfully smokey rockets, so I don't think a nitrocellulose-based propellant is used (but of course I could be wrong).
*having only seen videos on TV, the rockets don't appear to really jump into the air the way some do that I *know* have a high thrust engine. This is all guesswork though.- posted
