The computation of the time‐varying air loads of rotor blades is considered with the view of improving the treatment of unsteady aerodynamic effects in currently available programs without unduly increasing the required computational time. A computational model is proposed for accomplishing this objective and is evaluated by applying it to the two‐dimensional oscillating airfoil problem for which the exact solution is available.
