When and how to use Inertia Relief

Hello everyone,

 

I've been looking for Inertia Relief information because I have a feeling I need this for an aeromodel I'm designing.

Google Searches haven't been fruitful, so I came here to try and get some info.

 

The first thing I'd like to ask is: What is Inertia Relief and why do flying airplane simulations use them? How hard is it to get to know Inertia Relief?

 

My second question is: Where can I get some material to start looking into this matter? 

 

Thanks in advance!

    Hi

    as i understand:

    1) - ordinary structure is fixed!   K.u = F  => can find u = inv(K).F

    2) - special structure (rocket, airplane, submarin, floating parts) is not fixed => cannot invert K to find u

    Overcome? - Optistruct will add inertia forces to balance with F and make SUPORT somewhere to fix floating structure

    I am not sure about SUPORT, someone explained in this forum, please search the thread.
