I'm attempting some RasAero simulations. The simulation asks for a nozzle diameter. For the nozzle on the 6" rocket below, is the answer 0 inches, 6 inches or 4-ish inches?
I'd say it's 4 inches by the looks of it. I'm pretty sure RASAero is looking for the nozzle exit diameter to aid in calculating base-drag of the rocket when the motor is producing thrust and when it is not... I think the exhaust jet acts kind of like a boattail... All of this is what I think. I may be wrong or may have misinterpreted the question or just don't know what I'm talking about, so feel free to correct me!
Indeed. Rogers is looking for the exit dia, so 4" presumably. I'm watching, Jim!:wink:
