In this paper, an integrated torque converter design process is described which improves converter performance while reduces the design cycle time and number of hardware iterations. The process utilizes a suite of tools to achieve the objectives. For quick and flexible geometry layout, the TORUS DESIGN TOOL is employed to create the underlying 2D-torus geometry with given packaging constraints. The BLADE DESIGN TOOL is subsequently used to generate 3D sheet-metal type profiles for the impeller, turbine, and reactor blades. The tool is equipped with a parametric capability for blade curvature and blade angle control to meet the performance requirements. The AIRFOIL DESIGN TOOL utilizes a sophisticated, parameterized algorithm to generate the desired airfoil shape around the reactor camber-line for improved performance.
