January 2012 www.sname.org/sname/mt River. Nuclear power plant construction came to a stop after ree Mile Island, changing the market, and the company has closed their Memphis facility. As a cost-saving alternative, CBI oered to build the LCC in place on-site, and operate it at their now-closed Memphis facility, which had the size to house it. Dr. Bob Etter, of NSWC Carderock, has been with the LCC since its inception as chief engineer of the project oce responsible for design, construction, and initial operation of the facility. ?e 40-ft. long test section is 10 feet by 10 feet in cross section,? says Etter, ?big enough to mount a 36-ft. long model of a DDG 51 hull?weighing 5 tons fully rigged? suspended from the test section ceiling.? ese models are similar in size to those used in the largest tow tank at Carderock. ?But whereas you may be able to get data from a 30- or 40-second run in the tow tank, the LCC allows you to observe and gather data for hours uninterrupted,? adds Etter. e water ow can operate at a veloc- ity up to 35 knots, thanks to a custom-made 14,000 hp. variable RPM motor, built by GEC of the United Kingdom, with a 100-ft. long, 4-ft. diameter shaft turning an 18-ft. diameter axial ow pump, designed by Allis Chalmers (now Voith Seimens Hydro Power) in York, Pennsylvania. Pressure can be var- ied from 2 to 60 psia, which covers the range from a high vacuum to a high over pressure. Changing the pressure is important when examining cavitation at dierent depths and simulating conditions at much higher speeds up to 100 knots or more, Etter says. The overhead bridge cranes in the building, inherited from the CBI plant, are each capable of lifting 500 tons and can be ganged to lift 1,000 tons. Out by the water- front, a large 1,250-ton crane was used by CBI for heavy lifts on and o barges, and enabled the test section fabrication and the big electric motor to be lifted o the barges used to bring them to the site. e waterfront crane is still one of the larg- est on the Mississippi. Ownership of the crane was officially transferred to the Memphis and Shelby County Port Commission in August 2000 and is designated as part of the Memphis Heavy Lift Terminal. A contractor, Barnhart Crane, operates the heavy lift capa- bility for the Port Commission. ?In exchange for the crane, the Navy acquired a restrictive NAME RECOG þÿ nNITIO þÿ nNþÿ TThe Large þÿ CCavitation þÿ CChannel is named for Dr. William B. þÿ MMorgan, who was the head of the Hydrodynamics Directorate at David þÿ TTaylor þÿ MModel Basin for 22 years before retiring in 2001. þÿ AAccording to Bob þÿ EEtter, þÿ MMorgan worked at the þÿ MModel Basin for nearly 50 years. He was born in þÿ IIowa and educated at the University of þÿ IIowa and the University of þÿ CCalifornia, Berkeley. ?His main technical area was propellers and propulsion,? says þÿ EEtter. ?He published numerous reports and technical papers, some of which were of lasting signicance. He was a leader in the development and use of highly skewed propellers that improved acoustic and vibration performance of naval ships. He received several awards in his career including election to the National þÿ AAcademy of þÿ EEngineering in 1992.? ?Bill þÿ MMorgan hired me as þÿ CChief þÿ EEngineer of the L þÿ C CCC Project in 1984,? says þÿ EEtter. ?He was relentless in pushing for the L þÿ C CCC acquisition and viewed it as essential to the hydrodynamic and hydroacous- tic capability of the U.S. Navy. He was a lifelong leader in several engineering soci- eties and continues to participate in those organizations to this day.? þÿ TThere is also a campus road at þÿ CCarderock named Bill þÿ MMorgan Road in his honor, þÿ EEtter says. ? þÿ TThis kind of recognition is extremely rare in the Navy, testifying to the high regard the organization and his co-workers held for Bill.? 42_48_Lundquistfeature_SNAME_Jan12_P3.indd 4512/22/11 3:42 PM
