al93535 Posted September 2, 2006 Share Posted September 2, 2006 1 lb Rocket with 8 grams flash. I was testing an engine, so I put a lil flash on top. And again I forgot the prefire pic...

rocket Posted September 2, 2006 Share Posted September 2, 2006 Is it me or did that rocket have a longer flight duration than the others you’ve made? Link to comment Share on other sites More sharing options...
al93535 Posted September 2, 2006 Author Share Posted September 2, 2006 I did add a little bit of extra delay. But more importantly, the rocket was not weighed down by a heavy header. Speed of sound in air at 20degrees C = 1124 feet per second. Time delay from the light to boom, - 1.15 seconds. Distance of rocket from me 1292 feet.

itwasntme Posted September 2, 2006 Share Posted September 2, 2006 Whats a !Lb rocket ? http://www.pyrotooling.com/glossary_of_terms.htmThere you go ozzy. I think it comes from how heavy a cannon ball can be to fire from a specific size tube, so that would be a 1lb for a 3/4 in ID tube. Link to comment Share on other sites More sharing options...
shadopyro Posted September 2, 2006 Share Posted September 2, 2006 Very nice!!Just out of curiosity Al, what do you use for your delay? and which method? (-as in do you actually use an ejection charge or leave it just as a delay leading to the header? meaning that the payload goes off with the engine still attached) Link to comment Share on other sites More sharing options...
