The Development of a 2D Ultrasonic Array Inspection for Single Crystal Turbine BladesThis thesis describes the development of a new technique to solve an important industrial inspection requirement for a high value jet engine component. The work and the story told in the thesis stretches all the way from the fundamentals of wave propagation in anisotropic material and ultrasonic array imaging through to device production and site trials. The book includes a description of a new method to determine crystallographic orientation from 2D
