Abstract:

The fundamental objective of this program is to establish the technical feasibility of the transmission of hydraulic power through the use of pulsating flow andor pulsating pressure concepts. In this reporting period, the final portion of the component design program is presented. A method is shown for fluid volume control signalling, using a diaphragmtype transformer. A diaphragm-following sensor is used so that no physical connection to the diaphragm is necessary. In the area of analytical studies, a comparison has been made of the effects of a reciprocating cylinder-type source of pulsating energy versus the conversion of continuous flow to pulsating flow by means of an alternator valve. Also studied were the effects of system components on the dynamic response of the system. An analog computer setup has been completed data is being taken to supplement and confirm the data obtained from the miniaturized pulsating system. A study of the usability of a wave form of pressure pulsation indicated that it would be unsuitable for power transmission. Author
