This thesis examines the application of computer-aided design techniques to the field of turbomachinery. Specifically, the process of designing low- to medium-speed, axial-flow fans and blowers is discussed, and a Fortran program called FANJD is introduced. The first purpose of F AN3D is to perform the aerodynamic and mechanical calculations needed to establish the basic geometry of an axial-flow fan blade. Next, geometric modeling techniques are used to model the curves and surfaces of the blade, thereby completing the geometric description of the blade. Finally, FAN3D uses the CADCD component of the CADAM (CADAM, Inc.) Geometry Interface to automatically enter the three-dimensional blade model in the CADAM database.
