Abstract:

A Hydrofluidic Stability Augmentation System HYSAS developed in a previous program was modified to extend its operating temperature range. Baseline performance data, parametric test data, and a detailed analysis of the selected compensation approaches are presented. The compensated system was tested with MIL-H-5606 oil, and its gain remained within a or - 20-percent band over the temperature range from 50 to 180 F. Author
