Abstract:

A new generation of propellers with eight to ten blades operating at transonic flight speeds is now under development. These propeller blades are typically highly swept and twisted with small aspect ratios and supersonic tip speeds. A three-dimensional finite-volume computational code that accounts for cascade effects, hub-induced flow and nonlinear transonic effects is highly desirable. An effort to develop such a code has been undertaken by the author the results will be reported elsewhere. The present paper discusses the authors experience in mesh generation for this complex configuration. What is reported here is not new methodology but some practical considerations for a specific problem. However, the experience gained here is valuable to the developers of basic methodologies in generalizing their methods to accommodate these practical considerations, particularly for three-dimensional geometries.
