The main goal of Phase II is to validate the Phase I prototype and develop an integrated design and analysis tool for assessing large damage and blends for compressor IBRs on gas turbine engines and other blade systems. This tool will have at its core the automated analytical modeling of as-measured or as-expected airfoil blends for the structural and aero response to the shape change due to blends using the University of Michigan?s MAX method and Optimal Solutions Software?s Sculptor. The resulting technology will help expand the existing library
