Abstract

The paper summarizes current state-of-the-art equipment and techniques for the monitoring of loads during military aircraft operation. Monitoring systems are discussed which record strain, center-of-gravity motions, and control deflections, or the occurrence of selected load conditions. The raw data are reduced to sequences of stress peaks and troughs or to tabulations of peaks and coincident values of the recorded parameters. Finally, monitoring system cost estimates are provided for typical applications to individual aircraft tracking and loads and environmental spectra survey problems.
