摘要：

Signals from case mounted sensors are analyzed on-line to give integral and non-integral order blade vibrational stresses. Descriptions of the measurement technique, system hardware, data outputs, and performance criteria are presented. Calibration techniques for blade tip displacement to stress conversion and comparisons with conventional strain gage data are discussed along with planned improvements for a next generation system.
