Analytical method, which can be used for performance, stress, and vibration studies of helicopters and VTOL aircraft; applications are given for helicopter in flight regime from 80 to 160 knots; sample problem is carried out at 150 knots; rapidly convergent iterative procedure, which takes into account blade stall, is used to put rotor in trim; blade elemental lifts and drags are computed using wind tunnel airfoil data; rotor blade dynamics are determined using set of complex equations based upon extension of N.O.Myklestad's analysis for rotating beams.
