Book Synopsis Power Efficient Hydraulic Systems. Volume 2. Hardware Demonstration Phase by : Richard V. Hupp
Download or read book Power Efficient Hydraulic Systems. Volume 2. Hardware Demonstration Phase written by Richard V. Hupp and published by . This book was released on 1988 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy saving concepts for aircraft hydraulic systems were studied in a two-phase program. Task I was an investigation of methods and techniques to reduce overall hydraulic system power requirements by lowering system demands and increasing component efficiencies. Task II involved hardware demonstration tests on selected concepts. Task I: Study phase. A baseline hydraulic system for an advanced aircraft design was established. Twenty energy saving techniques were studied as candidates for application to the baseline vehicle. A global systems analysis approach was employed. The candidates were compared on the basis of total fuel consumption and six qualitative factors. Task II: Hardware demonstration phase. Two techniques demonstrated for energy savings were control valves with overlap and dual pressure level systems. Tests were conducted on control valves, a servo actuator, dual pressure pumps, and a lightweight hydraulic system simulator. Valves with 0.002 in. overlap reduced system energy consumption 18% compared to using valves with zero lap. Operation at 4000 psi reduced system energy consumption 53% compared to operation at 8000 psi. Pressure level switching was accomplished with excellent results. Keywords: Aircraft hydraulic systems.

Task II involved hardware demonstration test on selected concepts. Task I: Study Phase. A baseline hydraulic system for an advanced aircraft design was established. Twenty energy saving techniques were studied as candidates for application to the baseline vehicle. A global systems analysis approach was employed. The candidates were compared on the basis of total fuel consumption and six qualitative factors. Nine of the most promising techniques were applied to a Target System . The target system had a 28% reduction in energy consumption and an 868 lb weight reduction over the baseline aircraft. (jes).
