Dear Mohamed,

Yes, the blade root is located a distance of HubRad from the apex along the pitch axis, so ( HubRad + BldCg(K) ) is the distance from the apex to the blade center of mass. The -BldMass(K)*BldCg(K)^2 term is included so as not to double count the inertia effect already accounted for in SecondMom(K).

I hope that helps.

Best regards,
