Book Description
This paper presents an overview of current research efforts aimed at improving turbine engine structural instrumentation capabilities. Emphasis is placed on non-intrusive concepts which will be applicable to the advanced engines currently being designed for initial operational testing around the turn of the century. Technologies to be described include; blade tip deflection sensors to determine dynamic stress, thermographic phosphors to measure metal temperature, fiber optics to measure both temperature and steady-state strain while embedded in composites, and neutron diagnostic techniques. Advantages of the various systems, potential problems and limitations, as well as, an assessment as to when the various technologies are likely to be ready for actual engine test usage are discussed.
