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).
