Turbine Engine Loads Simulator (TELS) Radiographic Systems Requirements Study
Abstract
An analytical program was conducted to define the radiographic requirements necessary for the implementation of a radiographic system in a Turbine Engine Loads Simulator (TELS) facility. Data from the TELS studies provided the flight conditions which were used to determine the rotor case deflections of the engine under load. Source positioning and areas to be radiographed were located by analyzing the gyroscopic moments acting on the engine during centrifuge operation. An X-radiation source to measure internal clearances was selected after relationships between radiographic requirements and source parameters were established. Two-radiographic system concepts, on- centrifuge and off-centrifuge, were evaluated for integration into the TELS system. The on-centrifuge concept was selected because of its potential in offering more flexibility in source positioning. This concept locates as many of the critical components as possible near the center of rotation of the centrifuge and utilizes a linear accelerator with RF power. To implement the on- centrifuge concept in the TELS facility, preliminary design requirements were identified and recommendations for further study made.
