I'm in an aerodynamics class, and I have this canard configuration I'm trying to figure out for a final exam.(adsbygoogle = window.adsbygoogle || []).push({});

I need to find the sum of the moment about the center of gravity.

I may cannot be helped without the drawing being posted.

So far this is what i have:

Mcg = Mac - (lcg + lw)Lw + (lc-lcg)Lc

CMcg=-aw*alpha(hn-hcg) + Cmo

Each letter after the first letter (ie Mcg) is a subscript. So cg would be the subscript. I just dont know how to do that on here.

Anyway, my remaining equations which I can't seem to figure out is to derive expressions for hn and Cmo

Can anyone possibly help me with this or is more info needed?
