yeah, way to encourage people there. most people aren't too fond of loosing their limbs and when the dangers are pointed out will take steps to prevent harm. rather than just saying in effect "how dare you even think about it" perhaps take a minute longer and actually give the person some information about the whole scheme of things and help them to understand something about the type of project they are getting them selves into and what is required to be successful in the endeavour. (hell von braun was just out of high school himself when he was making and flying liquid bi-props I think)
I wouldn't think that a simple peroxide rocket would be beyond the scope of a really dedicated year 11 person however peroxide is really a pretty nasty chemical and some of the engine componentry isn't exactly cheap or easy to come by. I'd suggest for your first rocket motor looking at say a candy motor, some of which can be quite easy to make http://www.nakka-rocketry.net/ but being a solid fuel motor you can run into some fairly difficult legal hurdles. If that's not an option perhaps a hybrid motor I don't know too much about them personally but there are members on this list that do. Also of note is the article "small liquid fuelled rocket motors" (I think the title is) if you want I'll send that over to you, it has simplified calculations and theory for building kerosene/GOX (gaseous oxygen) motors with a worked through calculation, its a good intro to some of the more technical aspects of building these things without assuming PhD's in maths and physics. Whatever path you choose rocket making isn't something that you rush into, its probably a good idea to find somewhere other than the school oval to do testing ;-> (as nice as it would be to proudly stand there and show off as you bring your motor up to full thrust it may be frowned upon by some other, less.... adventurous members of the school community ;->) and generally hang around on the list etc. people here will generally answer any safety questions you have but first I'd recommend doing some reading see if you can get your school to buy Sutton (always nice when they do that) and have a look at all the people doing similar things online. With this stuff you always gotta rember you only have one set of arms/legs/eyes and that you are playing with things that can remove or damage said appendages in a split second. ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Saturday, January 11, 2003 4:12 PM Subject: Re: [ERPS] Help > Matt, > > With all due respect, people such as yourself and your 'teacher' are the > reason that we don't give out advice on making peroxide rocket engines. > It is *extremely* dangerous, and may well get yourself and others > killed in the attempt.
