The Vosper Electric system for coordination of controls in CODOG and COGOG sets has the following functions-cruise and boost engine throttle, boost engine SSS clutch engagement and disenagagement, propeller pitch control providing continuous matching to power demanded from engines with astern pitch facility, and actuation of fluid coupling scoop. The system does this by the positioning of a single lever for each shaft, duplicated in the machinery control room and on the bridge, and an associated rotary engine select switch. The system is based on the use of synchros to transmit information as to control position with associated servomotors actuating the various machinery controls to bring them into conformity with the position of the control lever. This means that the connections between bridge, machinery control room and engine rooms are purely electrical. The system is completed by the comprehensive relay logic and interlocks which prevent damage to the power plant through errors of control handling, and monitor the systems operation. Some details are given for major features of the system and typical applications.
