Abstract
This final report concludes a research contract to investigate the unsteady aerodynamic loads to which both horizontal and vertical axis wind turbines are subject. Full details of the unsteady aerodynamic methods for both wind turbine configurations are reported. The models used, part analytical and part empirical, have been developed and proven in the fixed- and rotary-wind aircraft and turbomachinery fields. The mathematical models have been encoded to form a suite of FORTRAN computer programs for use in the design and analysis of wind turbines. The programs may be used for the prediction of unsteady aerodynamic loads on a rigid rotor blade operating within an unsteady flow environment; rigid out-of-plane blade motion may also be accommodated in the existing programs. It is intended however that the aerodynamics programs be coupled with a suitable structural dynamics code to enable the determination of total unsteady loads. The aerodynamics programs are applied to representative machines and the predictions compared to available experimental data. Recommendations are made for further development and refinements. Application of the methods to the large wind turbines planned for the U.K. is described in separate Appendices. (author).
