testAlphaIIIStructure
Three fins in finset, so Ixx and Iyy are reduced by a factor of 3
Ixx reduced from 5.2771946530250825E-5 to 1.7590648843416942E-5
Iyy reduced from 1.3580770106050167E-4 to 4.526923368683389E-5
Total rocket MOI changed to Ir=1.8763734635622462E-5 and
It=2.1238394331365588E-4
testFalcon9HComponentMOI
Three fins in finset, so
finset rotational MOI changed from 0.00413298 to 0.001377661595723823
finset longitudinal MOI changed from 0.01215133 to 0.004050443797127646
testFalcon9HeavyBoosterLaunchMOIs
Two finsets, each three fins. Each finset's MOI are reduced as in
testFalcon9HComponentMOI, resulting in change to totals
Ir=0.013480523485489424, It=0.07017476021288252

OpenRocket
Overview
OpenRocket is a free, fully featured model rocket simulator that allows you to design and simulate your rockets before actually building and flying them.
The main features include:
- Six-degree-of-freedom flight simulation
- Automatic design optimization
- Realtime simulated altitude, velocity and acceleration display
- Staging and clustering support
- Cross-platform (Java-based)
