Aerotech I195J motor data is inconsistent and I would like to understand why (if possible).
This is the thrust curve from ThrustCurve.org:
Note the average thrust line is at 175N (not 195N as listed above the curve in the table of motor specifications).
This is what the thrust curve(s) look like in OpenRocket:
Compensating for the different Thrust axis scale, the yellow OR curve matches what is in ThrustCurve.org but OR uses the blue curve in simulations. Also, the "Show Details" tab in OR lists the Average thrust at 263N (different from 195 and 176 as above)
..and then over at RockSim it is this:
Can anyone explain what is going on here?
