    Tens of thousands of USD is blown up in the air and converted into a couple of movies which can be shown on Slashdot so that we can make insightful comments like this?

    I guess it'd be an improvement over strapping someone to a rocket then hoping they survived the landing so they could tell you about it.

  3. Isn't that just the way... by djupedal · · Score: 4, Funny

    So I build this nice, trim little single stage rocket (solid fuel), and my brother talks me into strapping another zero delay motor onto the bottom....it went fine until the tagged on motor lit the main motor....the rocket tumbled just for an instant, and when the main motor fired, the rocket was horizontal...it quickly made it to a nearby freeway and took out an aged Mustang. We figured since lunch was almost over we'd just as soon head back to the lab and quietly call it a day. A camera on that one would have shown one ticked off Mustang owner, I'm sure.

    Don't know if I have the nerve to sacrifice a DV camera...but maybe someone else's camera would be ok :)

      The tumbling is due to the fact that the full thrust us taking too much time to come. By the time full thurst came, the initial thrust had already lifted of the rocket and naturally due to that newton guy this thing would start tumbling, and when thrust was enough to pull it with speed it was horizontal.

      The solution would be to have a pipe around the rocket, by the time the rocket exits the pipe full thrust would be generated, and before that the pipe would keep it more or less straigt. Or if you can have such a motor design which can go to full thurst in minimal time it would be great, but that is expensive.

      If you want a safer demo of this you can try this. Take the ordinary fireworks rocket, the small one with the long stick which you put in a bottle and then ignote the fuse. You will see that the rocket goes quite save. Next take a smaller bottle and place the rocket so that the bottom of the stick is very near to top of botle. you will see that the initial thrust will have the rocket out of the bottle, but since the thrust is not enough yet the rocket will begin to fall sideways and by the time it falls power is max and you have a SSM!

      What you need to do is to read this web page on how to design a stable rocket before you build one. Basically it all comes down to the last paragraph on the web page, which tells you to make sure you have the center of gravity closer to the nose than the center of pressure.

      What you probably needed was to have more weight in the nose of the rocket and/or to use larger fins on the rocket. More weight in the nose would move the center of gravity toward the nose, larger fins would move the center of pressure toward the motor. If you had done this then the drag on the rocket from the air passing over it would have kept it straight up until it lost all upward velocity. Thus it would have not wobbled during the small delay between the first motor ending and the second motor getting up to speed.

    You mean a cheap thrill and valuable research data that may be used to make space travel cheaper, safer, and more efficient? Have you ever heard of a man named Werner Von Braun? You know, the man who contributed more working knowledge to the US space program than any other single person (granted, knowledge gained mostly from the German V2 rocket program, but we won't go there because it involved nasty things like slave labor and the US government deciding that his expertise was more important than justice) - he got his start making small liquid-fueled rockets about the size of the solid-fueled rockets shown in the referenced site. Who knows, maybe one of these hobbyists will end up working for NASA one day and inventing an O-ring that won't get brittle at low temperatures, or some other rocket safety improvement - thus preventing the Challenger thing from happening again.

    BTW, if you had actually RTFA or watched the videos, you would know that they recover the rockets using parachutes - which keeps the camcorders from breaking apart when the rockets reacquaint themselves with terra firma.

    If you really believe your own bullshit, what are you doing with a computer and an internet connection? For what you spend every month on your internet connection alone you could feed a starving child in Uganda for a year! I mean, really! Shame on you (and me)!

  13. How did they keep that thing balanced? by nounderscores · · Score: 5, Interesting

    With the camera sticking out of the side? Many, many rockets have been totally destroyed from just losing one fin. This series of rockets had a whole fairing bigger than a grapefruit protruding from it and it never tumbled. (except the one which had a parachute failure.)

    1. Re:How did they keep that thing balanced? by Anonymous Coward · · Score: 5, Informative

      You counterweight inside the rocket and streamline the bulge to minimize drag. At 200 lb weight, a 10 oz camera sticking 2" out isn't going to cause enough thrust to overcome the resultant stabilization forces from the fins. Also, these motors are producing upwards of 1000 lb (not precise number) of thrust distributed across the cross sectional area of the rocket. Once again, 10 oz vs 1000 lb, it's not much.

    I realize having Bill even reply to a Slashdot missive is far, far out into fantasyland, but here's what I've always been interested in.

    Bill went from being a (perhaps upper-) middle-class Harvard student to the richest person on the planet in the space of fifteen years or so. That *had* to involve a large lifestyle change. While I'm not at all interested in his present personal affairs, I am interested in how he handled the transition from college drop-out to industry icon. I'd like to ask:

    -How did you handle the transition from handling your own personal affairs (going down to the dealer to by a car, buying your own Pepsi and Fritos at the grocery, etc.) to having assistants and minions perform all these functions for you? When did this transition occur? At the time, did you view the transition positively or negatively (i.e., as one of the benefits of success, or one of the banes)?

    -When was the last time you drove yourself to work on public roads, or flew on a commercial airline flight? When the transition to limousines and personal aircraft occurred, what was the rationalization (e.g., more time available for work, increased prestige, etc.) for their use?

    -When did you first feel the need for 24x7 personal security? How did having people around you constantly affect your lifestyle? (Personally, I'd find it pretty creepy to have people monitoring me all the time--but even more creepy to realize that they were needed.)

    -You were single a relatively long time, then married a woman who worked at your office. As the richest bachelor on the continent, I can imagine that the competition among the single women at MS for your attentions must have made Machiavelli look like a Sunday-school teacher. Were you aware of this? If so, how did you address the resulting problems with office politics? Did you suffer from the insecurity, so common among the wealthy and powerful, that everyone that meets you is more interested in your money and power than in you?
