The US Navy's Helicopter Integrated Diagnostics System (HIDS) Program: Power Drive Train Crack Detection Diagnostics and Prognostics Life Usage Monitoring and Damage Tolerance; Techniques, Methodologies, and Experiences
Abstract
The evolution of automated diagnostic systems for helicopter mechanical systems has been greatly advanced by the Navy, in a program of systematic testing of drive train components having known anomalies (seeded faults) while simultaneously executing a suite of diagnostic techniques to identify and classify the mechanical anomalies. This program, called the Helicopter Integrated Diagnostic System (HIDS) was carried out using both an iron bird test stand and SH-60B/F flight vehicles. The SH-60 HIDS program has been the Navy's cornerstone effort to develop, demonstrate, and justify integrated mechanical diagnostic system capabilities for its various helicopter fleets. The objectives of the original program were to: This paper will describe the HIDS program background, development, system capabilities, and accomplishments; but will also focus on the most recent demonstrated drive train crack detection diagnostic techniques; aircraft component life usage monitoring philosophies and capabilities; and damage tolerance methodologies. Data and results from both the seeded fault "iron bird" test cell rig and flight test aircraft will be presented.
