The Garfield Thomas Water Tunnel is the U.S. Navy's principal experimental hydrodynamic research facility and is operated by the Penn State Applied Research Laboratory.〔(【引用サイトリンク】url=https://www.arl.psu.edu/about.php )〕 The facility was completed and entered operation in 1949.〔 The facility is named after Lieutenant W. Garfield Thomas, Jr., a Penn State journalism graduate who was killed in World War II. For a long time, the Garfield Thomas Water Tunnel was the largest circulating water tunnel in the world.〔(【引用サイトリンク】url=https://www.asme.org/getmedia/a780f1aa-900b-469c-9e79-0f125cd9cc93/188-Garfield-Thomas-Water-Tunnel-brochure.aspx )〕 It has been declared a historic mechanical engineering landmark by the American Society of Mechanical Engineers.〔(【引用サイトリンク】url=https://www.asme.org/about-asme/who-we-are/engineering-history/landmarks/188-garfield-thomas-water-tunnel )〕 Today, in addition to many of its Navy projects, the facility tunnel-based research has expanded into pumps for the Space Shuttle, advanced propulsors for ships, heating and cooling systems, artificial heart valves, vacuum cleaner fans, and other pumps and propulsors related products.〔〔 ==History== After the end of WW II, the US military started investing heavily in higher education nationwide. At the same time, Harvard terminated its Underwater Sound Laboratory (USL) which invented the first acoustical homing torpedo (FIDO);〔 consequently Penn State hired Eric Walker, USL's assistant director to head its electrical engineering department, and the Navy transferred USL's torpedo division to Penn State - where it became to be the Ordnance Research Laboratory (ORL).〔(【引用サイトリンク】) Historical Marker">url=http://explorepahistory.com/hmarker.php?markerId=1-A-288 )〕 The ORL eventually became the Applied Research Laboratory. The Garfield Thomas Water Tunnel was built at Penn State in cooperation with ORL by the ARL for further torpedo research. Construction completed on October 7, 1949, and began operating six months later.〔 Since then, the facility has expanded into viscosity, sound, wave, and wind research. In 1992, the facility underwent a complete overhaul. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Garfield Thomas Water Tunnel」の詳細全文を読む スポンサード リンク
