Newbie here so forgive me if I miss what may otherwise be obvious to the experienced.
I am trying to design a rocket for TARC using OpenRocket and no matter what I do as far as parachute, I can't slow down the decent rate. Plus when I use a larger parachute, oddly, the overall flight time decreases and the ground hit velocity increases.
I've tried to stick with parachutes from the list in the database. So, for example:
Estes 82426-30 24in. nylon = 32s flight time and 9.29m/s ground hit velocity
Estes 82426-30 12in. nylon = 34.2s flight time and 8.79m/s ground hit velocity
TARC requirement this year for flight duration is 41-43s. so I need to add about 10seconds, which seems like a lot to me. Maybe something is off with my environment settings in the sim?
I'm confused.
