Prashan_punk Posted March 31, 2006 Share Posted March 31, 2006 Hello everyone I am new in here I have some problems in making the solid fueled small rockets I cant find the proper chemical like KNO3......Can i use the burning material of a matchstick??? And whatelse can i do to make it???? Link to comment Share on other sites More sharing options...
woelen Posted March 31, 2006 Share Posted March 31, 2006 If you really want to do rocketry, then first do some more research and try to understand what is important. Just putting some stuff in a tube and hoping it will work as a rocket is not a wise thing to do. Also, perform a search on this forum, there already is quite some info about this subject.

YT2095 Posted March 31, 2006 Share Posted March 31, 2006 Can i use the burning material of a matchstick??? NO you CAN`T!!!!! that particular composition has a very low Critical Diameter, and will Detonate! your rocket will fail! Link to comment Share on other sites More sharing options...
insane_alien Posted March 31, 2006 Share Posted March 31, 2006 you could always buy the standard rocket motors in the hobby shops. i mean i'm going to take it your not really a professional rocketeer and building a huge ass rocket thats supposed to go 30 odd miles up the way.

akcapr Posted March 31, 2006 Share Posted March 31, 2006 you can PM me if you have questions i have some experience with homemade rocket motors. Link to comment Share on other sites More sharing options...
blike Posted March 31, 2006 Share Posted March 31, 2006 There are other sources of KNO3 which are readily available. However, buying a premade engine is way safer than making your own. Although I completely understand the thrill of building it from the propellant up, there is a lot of things to consider and a lot of safety precautions to take when making your own. I ended up not doing it because I was concerned about my inexperience in the field of mixing up explosives. Link to comment Share on other sites More sharing options...
insane_alien Posted March 31, 2006 Share Posted March 31, 2006 i just bought the premade ones to launch my r/c plane since i don't have a suitable runway for take off and i can't throw it fast enough. i could use a slingshot of sorts or try making a steam catapult like on aircraft carriers, but... fire. they are more than adequate just shove 4 under the wings and another one just under the tail and it can get it up to 45 mph in about 5.5 m Link to comment Share on other sites More sharing options...
YT2095 Posted April 1, 2006 Share Posted April 1, 2006 the best ones are the solid fuel types made with black powder and dextrin (as used by Estes), the have a reliable and reasonably constant burn rate, and being a solid grain (made under lots of pressure) have a good mechanical stability almost inherant in such a design. I actualy have home trials of this on video, and of about 30 rockets only 2 were succesful! you either get it right or you`ve made a great road flare or something that goes Bang in the long run, it works out cheaper to just Buy them Link to comment Share on other sites More sharing options...
Prashan_punk Posted April 1, 2006 Author Share Posted April 1, 2006 ..... Thanx guys but I want to try it...in the battery cover... Would it explode if it fails.............. Link to comment Share on other sites More sharing options...
chemfreak Posted April 3, 2006 Share Posted April 3, 2006 google 5 cent sugar rockets or just sugar rockets. the thing that i haVE NEEDS SUGAR, SALT PETER and , SUGAR Link to comment Share on other sites More sharing options...
KFC Posted April 6, 2006 Share Posted April 6, 2006 Witch Oxidizers Would Be Better Rocket Propellent: Ammonium Dichromate Ammonium Nitrate Ammonium Perchlorate Copper Nitrate Iron Oxide (black) Potassium Chlorate Potassium Nitrate Potassium Perchlorate Potassium Permanganate Link to comment Share on other sites More sharing options...
akcapr Posted April 6, 2006 Share Posted April 6, 2006 Depends on the motor you want to create, Ammonium Perchlorate is the most powerful oxidizer and is used in the large expert motors. If youre a beginner you should go with KNO3. Most of the other oxidizers are very/pretty impractical. Link to comment Share on other sites More sharing options...
[w00t] Posted April 6, 2006 Share Posted April 6, 2006 Ammonium Nitrate, Copper Nitrate, Ammonium Dichromate, Iron Oxide would definetly not work Link to comment Share on other sites More sharing options...
YT2095 Posted April 6, 2006 Share Posted April 6, 2006 any of the (per)Chlorates will work providing a suitable Reducer is used that`s mechanicaly stable. the potassium Nitrate also works and needs the same considerations, but is also less active as an oxidiser.
