Description

The Phase I Reliability Test was successfully conducted on the RFC/NDE Inspection System in November, 1985, at Systems Research Laboratories, Inc. The objective of the test was to ensure the RFC/NDE Inspection System’s ability to reliably inspect the crack-critical geometric features on representative F100 engine parts. Three types of EC reliability specimens (representing gas turbine engine disk geometries) were inspected: flat plates (web/bore surface); 0.316-inch diameter boltholes (with 45° chamfers on both sides of the specimen holes); and 0.177-inch diameter rivet holes. Thirty specimens of each type were used, with each containing either a number of fatigue cracks at various orientations and locations, or no cracks at all, as illustrated in Figure 1. The specimens were fabricated to satisfy the crack depth category requirements shown in Table 1.
