RASAero II Example Run

Full Metal Jacket - Flight 3

 

Presented below is a RASAero II software example run for the Full Metal Jacket - Flight 3 rocket, an O10000 powered high power rocket which was optically tracked to 37,981 ft.

The rocket geometry, rocket motor used, launch site and launch angle data, and the rocket weight are presented below. The Full Metal Jacket - Flight 3 configuration rocket was tower launched, and thus had no rail guides, launch lugs, or launch shoes.

The RASAero II rocket file for this rocket (Full Metal Jacket1.CDX1) is included in the RASAero II software download.
