OpenRocket Bug:
When the launch site altitude is 0, OR and RAS agree. However, when the launch
site altitude is non-zero, OR deviates significantly.
Example numbers for one of my test cases:
OR launch site 0 -> altitude 90K
RAS launch site 0 -> altitude 90K
OR launch site 5000 -> altitude 100K
RAS launch site 5000 -> altitude 120K
But here's the conundrum with the 5000 ft launch site:
At burnout: OR and RAS Altitude and velocity are identical
During coast: CDs identical, Drag force(lbf) identical,
Weirdness: Coast velocity very different, Max altitude very different
It seems if OR had a bug in the base simulator or atmosphere models, the 0
altitude sims wouldn't work either.
Taking suggestions. :-)
