Modifications to ARL Computer Programs Used for Design of Axial Compressor Airfoils.
Abstract
This report describes modifications to two previously published ARL computer programs used for the aerodynamic design and mechanical definition of axial compressor airfoils. A few of these modifications involve minor corrections to the referenced programs. The others are related to two features added to each program to increase its capability. The first of these allows each program to define 'splitter vanes' in addition to the primary blades. The splitter vanes defined are partial blades matching a selectable fraction of the aft portion of the principal blade camber line. The second feature added permits each program to punch appropriate data on cards matching the input requirements of the NASTRAN finite element stress analysis program. This is to facilitate the subsequent analysis of static stresses and deflections resulting from rotation and aerodynamic loads and the determination of blade natural frequencies and mode shapes.
