The present paper utilizes an earlier analytical wake model, which essentially applies to helicopter load analysis, to determine the performance of horizontal axis wind turbines. The advantage of this method is that it makes use of an integrated version of the Biot-Savart law for each part of the wake and thereby avoids some of the numerical difficulties present in the Biot-Savart law. Numerical computations were performed for a number of two-bladed rotor geometries and operating conditions. Results were compared with experimental data as well as with predictions of a full free wake method. Good overall agreement with both was observed.
