THE problem of calculating the motion of a helicopter blade presents many difficulties. Probably the most serious is the lack of knowledge of the aerodynamic forces acting on a blade, but a second major difficulty arises when the equations of motion have to be solved. The first and second harmonics may be readily obtained, but the higher harmonics can only be calculated at the expense of considerable effort. This is especially true if the effects of elasticity and varying tip-speed ratio are taken into account.
