tentacles Posted June 11, 2008 Share Posted June 11, 2008 While I was visiting FrankRizzo, we made a few rockets (that mostly failed in hilarious ways) including a MnO2 - Al rocket. Basic construction was... MnO2 and 325 bright flake Al pressed using BP core burner tooling. At the very top of the core was 1/2 increment of strobe mix to light it up (it is a thermite after all). Above the core was some BP. 75-15-10 meal I think (pressed in). I think you'll like it... Check it out frame by frame if you have a good player. And we were worried the 325 flake was too slow! The rocket had more thump than the 10g flash header (+10 Ti). http://www.apcforum.net/files/MnO2-325flake-sound.avi Link to comment Share on other sites More sharing options...
fizeau Posted June 11, 2008 Share Posted June 11, 2008 I really like unusual rocket fuels! And the CATO was very nice. Is there any chance to slow down the burn rate for a short flight? Think I´ll do some experiments with MnO2...and not for thermite Link to comment Share on other sites More sharing options...
TheSidewinder Posted June 11, 2008 Share Posted June 11, 2008 Nice "bomb on a stick" there! Did you have any that worked as you hoped? If so.... video? Link to comment Share on other sites More sharing options...
Bonny Posted June 11, 2008 Share Posted June 11, 2008 if you could get it into the air it would make a nice looking shell! Link to comment Share on other sites More sharing options...
tentacles Posted June 11, 2008 Author Share Posted June 11, 2008 TS: The others were BP (cored) and whistle (on fountain tooling in the rain). Here's a link to the other 6 vids I got (total 8 rockets, didn't get one on vid). Keep in mind that we pressed these rockets in the rain. The whistle rockets are K benz based. http://picasaweb.google.com/EdwinGuy/BrianSPhotosAndJunk Just ignore the pictures of my argon tank, and admire my hops. The larger plant with 2 stalks has overnight started wrapping the nearer stalk around that wooden marker pole. I've put up a piece of string for the other to climb up that trellis.

TheSidewinder Posted June 11, 2008 Share Posted June 11, 2008 Rockets pressed in the rain.... yeah, I see that was a problem. Even the whistles. On a brighter note, the hops look damn fine! Link to comment Share on other sites More sharing options...

On a brighter note, the hops look damn fine!HAHA...nice video man! So, I dessicated a sample of that BP we used for those end-burners...~12% moisture. oops. I guess I forgot to fully dry that powder before storing it away last fall. I'm sure the rain didn't help much either. Using the fountain tooling to press those whistle rockets probably wasn't a performance enhancing endeavor either. A 1/2" core is maybe a bit small. We had fun..that's all that matters.

psyco_1322 Posted June 12, 2008 Share Posted June 12, 2008 Yah that may not work to well for whistles. You could have make hybrid 1s though. Link to comment Share on other sites More sharing options...
