Abstract : In a recent paper, Jones and Moore have developed a simple numerical lifting surface technique for calculating the aerodynamic coefficients on oscillating wings in subsonic flight. The method is based on the use of the full lifting surface theory and is not restricted in any way as to frequency, mode of oscillation or aspect ratio when M less than 1. In this study, this simple but general method of predicting airloads is applied to helicopter rotor blades on a full three-dimensional basis. (Modified author abstract)
