Abstract:

In this work a method for constructing wave propagation paths on aircraft modeled with nonuniform rational bi-cubic splines has been proposed and investigated. Procedures for dealing with artificial discontinuities due to geometric mis-matches of spline patches have been developed and implemented in numerical codes.
