Tie electromechanical tether cable for RUWS employs a Kevlar strength member andsingle coaxial electrical member. Power and comnand/control signals to the vehicle and the

____wide bandwidth video and sensor data from the vehicle are simultaneouslv transmitted oi thetether cable through use of time and frequency multiplexing techniques.

Hydraulically-powered systems wer- selected to perform the RUWS mechanical func-tions because of their tolerance to high ambient pressures and their inherent versatility throughsimple variable-speed controls. Hydraulic systems are compact and offer a low weight-to- Apower ratio. Weight is significant because of the high cost of syntactic foam that is needed toprovide vehicle buoyancy at deptls to 6.100 metres (9,000 psi).

Another lmiajoi factor for selecting electrohydraulic propulsion systems over electricpropulsion systems was that controllable electric drive motors would cause a varying electricalload which would produce large line voltage variations at the vehicle due to the IR (current

X cable resistance) loss in the cable. The RUWS system uses a 8.315-metre (24,000-foot)coaxial electromechanical cable that transmits up to 45 kVA of 60-Hz. 3000-volt power tothe PCT and vehicle. Tie electrical control and inforniation signals ,re time-division multi-plexed onto the coaxiai power cable. Tie sensitivity of the multiplexing circuitry requires afairly constant voltage level. Large voltage regulators with their attendant high heat loadwould be required for large line voltage variations. By operating a fixed-displacement hydrau-lic pump at a constant speed and throttling excess oil flow through a relief valve the electricpump-drive motor is under constant load. thereby minimizing the electrical current variation.

Hydraulic propulsion systems. howvever. tend to produce more noise than electric pra-pulsion systems. Components in a hydraulic system considered to be major noise producersare pumps. motors and valves.

Tie objective of this program was to select several commercially available hydraulicpumps, motors and valves as condidate components for the RUWS electrohydraulic propul-sion system, perform acoustic tests on the components, and select the quietest componentsthat would fit the requirements for the RUWS hydraulic system.

SYSTEM OPERATING REQUIREMENTS

= The components in RUWS sulbmersibles requiring electrohydraulic power consist ofthe thruster drives, vehicle tether winch and traction drives, and the vehicle's work suit (mani-pulators. camera gimbal. and special tool drives). Figure 2 depicts the RUWS vehicle, itsthrusters and work suit. The thruster arrangement provides four degrees of propulsive control:vertical, transverse, fore and aft, and yaw.

The vehicle work suit (reference 1) consists of a seven-function manipulator, a four-function grabber. a TV-camera pan and tilt gimbal, and various work tools. Tie work suit iselectronically controlled and hydraulically powered. To meet the design pefornance goalsfor the work suit. 1000 psi was needed for the hydraulic supply pressure. and therefore 1000psi was selected for the RUWS vehicle system pressure. Candidate hydraulic componentsselected for use on the vehicle were tested at 1000-psi differential pressure for the acousticcompatibility evaluation.

The electric motors were necessar, for test purposes to drive the pumps. Their noise outputswere very low and did not significantly ctntribute to the results of the piump tests (graphsA-101 and A-102 in appendix A).

COMPONENT EVALUATION

The facilities and procedures used in evaluating the candidate components are des-cribed in the following paragraphs.

TEST FACILITIES

The initial tests were conducted at Ku Tree Reservoir (figure 5) in central Oahu. Th@issite was desirable because- of its large water volume and its bottom profile. which minimizedreverberation at the hydrophone. Because of logistics problems encountered at remotelest site, however, the tests were continued in a Doughboy swimming pool. 28 feet in diameterby 4 feet deep (figure 6). The reverberation off the walls and bottom of the pool produced an

CONCLUSIONS

There are sever.l m.Jnisms ol noise g~eneration in hb draulic si'stems. The malormechanisnis are cavitation, machinery and Iflid f'low.

In hydraulic compo cuts and systems of' which noise was not a design consideration.cavitation could be thle most serious noise source. Cavitation occurs when, at sOlle point illthe system, the local pressure is less than tile vapor pressure or the hydrauilic fluid and bubbles-ire formed. This can occur in areas of high~ velocity flow and intese turbulence. Then, at a1

- point downstream, thle pressure rises above the vapor pressure and thie bubble collapses(implodes) producing broad banld noise extendig from the audible into the inaudible fre-

By maintaining thle pressure throuighout thle s'ysteml at a level hgh enlough that even inareas of' intense turbulence the local preisure dtoes not drop below the vapor pressure of thlefluid, cavit'ation would be eliminated, The components tested1 showed a reduction in noiseoutput when return line pressuires were maintained above 450 psi. This is the condition of'suibmersible, hydraulic systems that have reservoirs compensated to amibient pressure in thedeep ocean. It may also be accomplished with a closed system with a sualed reservoir pressur-ized to 450 psi.

Hydraulic components are being dlesigned and produiced without a tendency for cavi-zt tation. Sharp-edged orifice valves are highly susceptible to cavitation because of the high fluid

velocities and turbulence onl the exit side of' the orifice. Several throttling techniquesusing" small-cross-sectionl multiple path~s are presently employed by manufacturers makingquiet throttling valves. These techiniques keep flow velocities and turbulence at levels Which(d0 not produce cavit Jion.
