Hydrofluidic Flight Controls 700793

This paper describes the application of hydrofluidics to stability augmentation systems. Criteria for selecting fluidics for a specific application are presented. A typical hydrofluidic system is presented to show principles of operation, transfer functions, and component performance. A brief description of the power supply system shows how this system is integrated into existing aircraft without extensive modifications to the hydraulic power supply. Major problem areas of noise, leakage, and contamination are discussed.
