Paper Abstract

For years the development and testing of aero gas turbine engines has been hampered by the inability of engineers to penetrate the opaque casing walls and see and measure the growths, flexures and movements of the metal components and the fluid dynamic movements within lubrication systems in gas turbine engines. High Energy X-ray imaging has been developed to visualise and measure the movements of metal components and 'cold' neutron imaging to visualise and measure lubrication system dynamics. 'Direct' and 'Indirect' type intensifiers have been used and the research, development and application work is described. The radiation sources are described for x-rays and cold neutrons together with Oude Delft 'Delcalix' isocon based and Westinghouse Ebsicon based Indirect Imagers. Thomson CSF Direct Imagers for Low and High Energy X-ray and Neutron radiation are described together with a special Multispectral Imaging System for high Speed X-ray cine. Finally the application of the Kodak Spin Physics SP2000 with a Thomson tube for x-ray Imaging at 1000 pictures per second is described.
