[Jsbsim-devel] Slaved FDM

[David C. <dav...@co...>]

Happy New Year!

I was visiting the openAE website and the image of Virgin Galactic's launcher/spaceship duo reminded me of earlier dicussions here concerning running JSBSim in a slaved mode.  To be clear, by "slaved mode" I mean running the FDM for the carried object, in this case the spaceship, in a mode which looks to an outside application for position and orientation.  In this case the slaved object would run the EOM backwards to keep the velocity and acceleration values populated with meaningful values, so that at the time of release (when the object is un-slaved) the EOM can then be run normally with proper initial values all along the EOM chain.

Would this be a good time to renew discussion?

Note:
In this scenario I see the launcher as an AI object only, not as a JSBSim-powered object.
