CG located on fuselage?
Hi gentlemen, I found a CG calc tool that used the dimensions of the wing, tail, and distance between the wing leading edge and the elev leading edge. I have used this before with some success. For grins and giggles I played with changing the distance between the two leading edges. The recommended CG kept moving rearward. I went as far as to extend the distance enough where the airplane would probably not fly but I was trying to see where the CG would end .Well I got one spec that put the CG in the middle of the fuselage between the wing and the tail. I am trying to understand the physic behind this. I assume that the center of lift would always be somewhere on the wing. Would this work with the cg that far off the wing. If anyone can explain why the tail distance from the wing affects cg. I understand that the longer the arm the smoother the reaction etc. but how does this affect cg? anyone help/And thanks.
