Book Description
Presented are the results of exploratory experimentation that was conducted in NAPTC Rotor Spin Facility to provide criteria for the design of turbomachine rotor burst fragment containment rings. High-speed photography was used to study containment processes involving freely supported rings of different materials and a variety of rotor and flat disk fragments.

Book Description
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).

Book Description
The program objective is to develop guidelines for the design of optimum weight containment rings for turbine engine rotor fragments. Rotor/disk and blade containment experiments were conducted using strain gage instrumented containment rings. The tests were conducted to study, by means of high-speed photography and strain measurements, the interaction that takes place between the rotor fragments and containment ring during the containment process. The recorded information was supplied for use in the TEJ-2 or CIVM JET-4B computer programs which are being developed for use in the optimum design of containment/deflection devices. The characterization of blade and rotor fragment behavior and containment ring response was made possible by photographing blades and rotors intentionally modified to fail at their design operating speed.

Book Description
The NASA sponsored Rotor Burst Protection program has produced the first high speed photographic sequence of an intentionally failed rotor within a containment device. This technical achievement has provided a means to study the fragment-containment system kinematics and material performance associated with disk and blade failures. The results of the first twenty-one tests provide data that can assist in establishing basic guidelines for the design of containment systems. Experiments providing information relative to the complex motion of disk and blade fragments for a failed rotor, and the effects of radial clearance, stress concentration, and material properties are reported. The theoretical derivation and related curves for the energy distribution of fragments from a rotating flat disk provide the total, translational, and rotational kinetic energy per fragment for combinations of fragment included angle and radius ratio are presented. A survey of uncontained failures occurring in U.S. Commercial and Naval aviation experience is reported. Test equipment and techniques are discussed. (Author).

Book Description
Results of experimentation to determine design guidelines for turbine rotor fragment containment rings are presented in this report. The project consisted of two tasks. Task 1 was an investigation of the containment characteristics of cloth rings. Task 2 determined the engine casing thickness required for single and triple blade containment. This effort was conducted as part of the overall Rotor Fragment Protection Program. Rotors; Fragment protection; Blade containment; Rotor failures; Containment rings. (mjm).
