摘      要：An interactive computer aided preliminary design system has been developed mainly for gas turbine engine rotors. The design system covers three parts: disks, shafts and rotor dynamics. A nu- merical optimization package called MPOP is used to minimize the weight of disks, shafts and optimize the arrangement or stiffness of bearings for rigid or flexible rotors subjected to certain constraints of sizes, shapes, stresses, deflections, stiffness and frequencies. Various forms of disks, shafts, rotors and structure-analysing result curves are displayed on the screen. Designer may select, inspect or modi- fy the results interactively. The integrated design of structure, optimization, strength and rotor dynamics has improved design quality and reduced turnaround time during preliminary design phase of gas turbine engine develop- ment. As an example, a real preliminary design of an aeroengine turbine rotor is described.
