Hey R2K. Nice site, you're in my bookmarks. I'm a once real rocket guy (okay, payload guy, but I've been inside a Titan IV extended fairing) who's now into the home made kind. We had a commercial shot go bad once, with two of our satellites on board. Rocket went ass over teakettle at about 50K feet and the RSO blew it up. One of the satellite program managers jumped up and yelled, "I can see my bird!" as the thing disintegrated. Weird how people react, but you can't get too upset when your job consists of strapping fifty million dollars worth of radio to a million pound bomb.Keep up the good vids.Jimmitude
Thanks for the comment, and yes please visit us often here. We would love to have an expert give some input when he can. It is always sad when a rocket has to be blown up, but I personally say let it fly a bit more than 50k. I mean just see it if does something cool first like skim across the ocean! :)
Just for fun, count the delay between the big flash of the explosion and the sound. The spectators are VERY close (far closer than US range safety would allow, that's for sure).For perspective, the Soyuz Fregat contains about 160 tonnes of fuel and oxidizer at launch, which is roughly equivalent to the explosive payload of 6 fully loaded B-52 bombers.
Yes, what fuel is being used in there? I expect something like rp1 and o2 right? That would make some heavy fumes, add to that any hydrazine or irfna or any other nasty bits that might be in there in small amounts. They are lucky, even with a small difference in burn, the rocket would have landed on top of them and they all would have been burned alive like those poor Russians.
Yup, it's almost entirely LOX/Kerosene. The uppermost stage (the Fregat in Soyuz Fregat) uses N2O4/UDMH, but it only contains ~4 tonnes of propellants.
