Proposal for diesel electric propulsion scheme based on a-c system, working in conjunction with controllable pitch propeller, has been submitted to White Fish Authority, Hull, by Siemens (United Kingdom) Ltd; it involves three diesel alternators supplying two pole-changing squirrel-cage motors geared to single shaft and is offered at first cost stated to be less than that of comparable d-c installation; two propeller motors have output of 2000 hp at 1480 rpm while on four-pole operation with reduction to 1200 hp at 980 rpm when based on six poles; schematic diagram shows layout.
