Numerical Evaluation of the 3-D Harmonic Kernel.
Abstract
In the current method of numerically evaluating the kernel function of unsteady lifting surface theory, a set of constants due to Laschka is used in a manner whereby much of the accuracy and reliability of the original Laschka results is lost. The cause of this loss is discussed, and a new set of constants is presented which is (a) somewhat simpler than the Laschka set, (b) restores the lost accuracy to well within the practically required degree in the range of small values of u, and (c) extends the range of acceptable accuracy to larger values of u. Non-planar lifting surfaces are included in the discussion.
