    Abstract
  • To meet the design requirements of high thrust-weight ratio engine, the topology optimization was carried out with the evolutionary structural optimization algorithm based on the conventional turbine disk, and the shape of twin-web turbine disk was determined. A work of the twin-web turbine disk including finite element analysis and size optimization was provided according to the results of topology optimization. And the mass of the twin-web turbine disk reduces by 23.6% compared with the conventional turbine disk at the same stress level. A rotating three-dimensional photoelastic test was carried out, verifying the rationality of the design and the accuracy of the calculation results.
