Waukesha T400 Turbine Powers Hovercraft FIRST FOR THE NEW YEAR: The first meeting of the 1973-74 year of the San Diego Section of The Society of Naval Architects and Marine Engineers was held at the Hilton Inn in Mission Valley on September 19, 1973. Following the social hour and enjoyable dinner, R.J. Ziobro, manager of marine engineering at Aqua-Chem, Inc., Water Tech- nologies Division, Milwaukee, Wis., gave a very interesting talk on shipboard distilling plants. Current shipboard distilling plants can be broadly classified as being of the flash- type and nonflash-type, and variations within these classifications were defined. Ad- vantages and disadvantages of each type were discussed and were related to interfacing with steam, gas and propulsion systems. Shown above at the Hilton Inn meeting are, left to right: R.E. Nichols, papers chairman, San Diego Section; Joe Busch, chairman, Northern California Section; Mel Good, chairman, San Diego Section; Mr. Ziobro, speak- er; R.P. Nolan Jr., secretary-treasurer, San Diego Section, and David Krepchin, vice chairman, San Diego Section.

The particular application is the installation of twin T400 turbines in a large commercial hovercraft being constructed in England by Enfield Marine. The 40-foot by 20-foot power craft is designed to carry a 3j^-ton payload at 45 knots, and will be used between ports in England and Erance. Use of the freight hover- craft will enable cargo to be loaded directly from the warehouse, moved to and over the water, and delivered to the other port for unloading. This concept eliminates the need for docks, as well as the use of multi-carrier transportation. The twin Waukesha T400s used in the vessel are the marine ver- sions of the rugged standard indus- trial power plants that have found wide application in the petroleum and power generating fields. The T400 engine provides broad application capability through the use of a unique fixed/free shaft ar- rangement. This provides the ex- cellent response of a fixed shaft turbine for power generation, yet provides the necessary high torque characteristics of a free shaft tur- bine for variable speed applications. An over running clutch provides both the variable speed characteris- tics of a two-shaft turbine and the constant speed advantages of a single-shaft configuration, required for power generation. In addition, the T400 low exhaust emission levels easily meet the pro- posed EPA 1975 standards. The T400 is rated at 400 hp con- tinuous with a maximum rating of 485 hp with multi-fuel capabilities.
