Sprint Experimental Rocket Launched 6/12/1999 and 7/10/1999
The first and second launches of John Cipolla's nearly finless Sprint ABM experimental rocket were successful. The Sprint high power rocket was powered by the RMS 54/1280 rocket motor with a J415-6W reload having a maximum thrust of 100 pounds and burn time of 3.59 seconds. AeroDRAG, VisualCFD and AeroCFD were used to correctly predicted the vehicle reached 1,076 feet at apogee with a maximum velocity of 226.15 ft/sec at burnout. Dual timers recovered the main booster and the nose cone on separate parachutes in perfect condition. These two launches provided the database required to validate AeroRocket's computational fluid dynamics programs and flight analysis programs. Also, see photographs of the successful AeroRocket Sprint ABM exact scale model rocket.
