Aircraft turbine rotor failure is characteristized by the release of high energy fragments capable of penetrating the engine casing. The fragments could cause fires, loss of aircraft control, hull damage, and occupant injury. Lightweight armor material technology has been proposed as a potential alternative to traditional steel containment technology. The materials investigated were: fiberglass/polyester, fiberglass/phenolic, Kevlar/phenolic, fiberglass/polyester-steel, fiberglas/phenolic-steel, Kevlar/phenolic-titanium, and titanium. These materials were evaluated in a rotor spin-pit facility using the second stage power turbine rotor from the Avco-Lycoming T53 turboshaft engine. Spin-pit testing has indicated that these materials were all successful in containing the high energy fragments produced by the failed turbine rotor.
