Abstract

An approximate analytical large deformation method, based on the Nadai deformation theory, for calculating the burst speed of aeroengine disks, is presented in this paper. The basic equations are developed and the calculation procedures are illustrated. The burst speeds are calculated for some tested disks, and the calculation results are compared with the test results; the differences between two results are shown to be less than 8 percent. This shows that the new method is both simple and convenient. Therefore, it could be employed in the development of aeroengine disks.
