Thanks Joe. What an exciting concept. Having got really enthusiastic, I thought I would roughly calculate how high one of these little rockets could raise the orbit. Given that one rocket reload pack has 40 Newtons of thrust and lasts for about one second We have 40 Newton seconds of specific impulse. The mass flow rate is 18.6g in one second or 0.0168kg/s So.....the ISP (a bit vague here) is around 219 seconds (ave thrust / mass flow rate / 9.81ms^2) Which should get a 3.7kg satellite's apogee about..... 40km higher. So...Not enough for P3E then Oh well, not so exciting after all. Time for a beer. 73 David G0MRF In a message dated 17/01/2012 03:56:37 GMT Standard Time, rhyol...@nettally.com writes:
Has anyone seen this. I am surprised a shuttle mission permitted this type of booster. From what I believed, safety concerns prevented most types of boosters. http://www.rocketryplanet.com/content/view/3706/30/#axzz1jgQ85qx1 -- Joe Leikhim Leikhim and Associates Communications Consultants Oviedo, Florida www.Leikhim.com jleik...@leikhim.com 407-982-0446 Note to GMail Account users.
