WebbA simple method of estimating the pitch-damping coefficients for axisymmetric flight bodies has been developed. The method is suitable for preliminary design and parametric studies. The procedure is based on concepts from slender body theory, but the method significantly improves the accuracy of the results through the use of correlation functions.
