High Energy 8 MeV x-rays are used to determine metal component movements for engine performance improvements and integrity confirmation, using film. Real time video is used for transient events. Low energy x-rays with high speed cine fluoroscopy have been used to analyse molten metal flows in the turbine blade casting process. Cold neutrons and low energy x-rays have been used to analyse two phase flows and oil distribution in the Gem engine oil scavenge system. Positron emitting isotope techniques are being developed to determine fuel and lubrication system dynamics. The images captured by these systems are then processed by digital techniques and pattern recognition and crosscorrelation is carried out. Measurements are made from the film and video images using two and three dimensional photogrammetric methods.
