ROTOR BURST PROTECTION PROGRAM.

Abstract : The NASA-sponsored Rotor Burst Protection Program reports its continuing study into the kinetics of intentionally failed rotors within fragment control systems and the influence of certain important system parameters on the containment/control process. High-speed photographs have recorded the complex action of bladed rotors which more closely approximate realistic turbomachinery operating conditions than did the earlier RBPP testing. The test observations should assist the containment design engineer. A survey of uncontained failures occurring in U. S. Commercial and Naval aviation experience is reported. A detailed study of commercial and military specifications regarding rotor integrity substantiation and containment criteria is presented. (Author)
