Abstract : The integrated intensity and the angular position of a Bragg diffraction peak are both related to temperature. A multiphase test program, specifically designed to explore nuclear methods, has determined that strains and temperatures in the static and rotating components of a gas turbine engine can be measured nonintrusively using neutron diffraction techniques. In parallel with these efforts, a study concluded that there are several 'portable' neutron sources that are suitable for the neutron radioscopic examination of an operating gas turbine engine.
