Rotor Burst Protection Program:Experimentation to Provide Guidelines for the Design of Turbine Rotor Burst Fragment Containment Rings.

摘要

Presented are the results of a program of rotor burst containment experimentation that provides guidelines for the design of optimum weight turbine rotor disk fragment containment rings. These guidelines were derived by establishing the relationships between a measure of the ring's capability to contain fragment energy with respect to it's weight (the specific contained fragment energy - SCFE - derived by dividing the rotor burst energy by the weight of ring required to contain this energy) and other significant ring and rotor variables such as the: rotor tip diameter; number of rotor fragments; and ring radial thickness and axial length. The experiments consisted mainly of bursting 14 and 31 inch diameter turbine rotors into encircling containment rings made from centrifugally cast 4130 steel. Rules are given for achieving optimum weight ring designs. (Author)
