Design Criteria for an Inspection and Diagnostic System for the UH-1D helicopter

Abstract

The objective of the program is to accumulate sufficient vibration and temperature data to establish base-line operating levels and to determine maximum limits for use in the development of an automatic diagnostic and inspection system for the UH-1 series helicopter. Samples of data were taken from 12 instrumented helicopters at controlled times by three automatic self- calibrating data collection systems which were moved between the aircraft twice each day. The relevant data were processed by a high-speed digital computer through a number of passes to produce edited calibrated printouts and magnetic tape records of each acceptable data sample. Maintenance records on the instrumented helicopters were reviewed, summarized, and correlated with measured changes in temperature and acceleration level during the same period.
