Two computer methods for the design of radial out-flow turning vanes are described. The key requirement was for vanes with simple shapes that could be machined easily and inexpensively in-house. Two design approaches, one using circular arcs for both suction and pressure sides and one for wedge-arc shaped sections were developed. Requirements for the general design procedure arose in two exploratory projects, a Rotary Detonative Wave Engine RDWE and a high speed Centrifugal Diffuser Test Device CDTD. The RDWE was analyzed first and found to be potentially inefficient in its original configuration. Preliminary design for a high speed CDTD flow generator was completed, incorporating wedge-arc radial outflow vanes. An attempt to analyze the flow through the geometry using the Eidelman-Godnov Euler was initiated. Keywords include Radial outflow vanes Transonic swirl generation Wedge-arc blading.
