RESEARCH INVESTIGATION OF HYDRAULIC PULSATION CONCEPTS.
Abstract
This final report covers a program during which Republic made a research investigation of the technical feasibility of the transmission and utilization of hydraulic power through the use of pulsating pressure or pulsating flow concepts. It was concluded that the pulsating flow means were suitable for power transmission, whereas pulsating might be adapted for signal transmission. The type of system currently in greatest use in aerospace vehicles is the constant pressure flow demand system that utilizes a pressure-compensated variable delivery pump. Republic believes that an adaptation of this system to the requirements of a pulsating system will produce the most desirable means of control from the standpoints of efficiency, simplicity, and reliability. Our major efforts have therefore been concerned with the design of such an adaptation. The research investigation was carried on by two methods: (1) the design effort, and (2) the analytical method. The laboratory effort was limited to relatively simple experiments intended to verify or facilitate analytic results. The system analysis was augmented and verified by data derived from a miniaturized pulsating hydraulic system. As a result of its research investigation. Republic recommends that the effort be continued and that a representative operating pulsating system be investigated to confirm the analytic data and that further investigations be made into the applicability of pulsating hydraulic concepts for vehicular use.
