PROTOTYPE NONDESTRUCTIVE INSPECTION EQUIPMENT FOR DETECTING FATIGUE DAMAGE IN DRIVEN GEAR OF SH-3A HELICOPTER TRANSMISSION.

Abstract

A prototype equipment was developed for the detection of fatigue damage in helicopter gears using the magnetic perturbation method. A description of the magnetic perturbation technique is presented, along with a summary of experimental results obtained from prior work. Fundamental design considerations and laboratory design experiments are discussed. Photographs of the laboratory setup and the prototype equipment are shown, and features of the prototype are presented. Tests and evaluations conducted during development of the prototype are described, and typical data recorded during laboratory evaluation of the prototype are presented. (Author)
