| Abstract: | The stressed state and stress concentration in sloping cooling circuits of the rim part of a disk of a gas-turbine engine are studied by using a three-dimensional finite-element model. It is shown that the numerical values of the stress concentration factors do not exceed their designed values. Translated from Problemy Prochnosti, No. 3, pp. 78–82, May–June, 1998. |
