Constraint set for accelerating aircraft?
Constraint set for accelerating aircraft?
(OP)
I'm trying to wrap my head around what a reasonable constraint set would be for an accelerating body. I have a helicopter that will be accelerating upwards, and the acceleration load will be applied to the entire body. I'm struggling with the idea that I would just apply a typical 3-2-1 constraint like a body in equilibrium, or clamping it at some reaction point. Just doesn't seem that realistic, and I'd get huge artificial constraint forces in either case. Is there a more accurate way of doing this kind of analysis?

1) you restain only 6 dof, and
2) the structure around your constraints is stiff enough to effectively transfer the constraint into the bulk of the model.
