SPECIFICATION OF A CONTROL SYSTEM FOR A NEW MARINE GAS TURBINE

The decision to develop the Spey gas turbine for marine propulsion provided the opportunity to introduce new control system technology. The experience gained with the Olympus and Tyne systems over a twelve year period identified the areas needing improvement and could be coupled with recent technological advances to produce a system for the 1980's. The design of the control system has progressed to the stage where breadboard systems are in development use. The paper does not discuss the hardware employed but rather the interpretation of the customer's statement of requirements into a working specification. The subject matter concentrates on those aspects where there are a number of alternative approaches or where conflicts between requirements exist and analyses the route to the adopted solution. These aspects include the choice of system technology and its integration with proven components, the selection of parameters to provide optimum system control, the design to achieve rapid diagnosis, repair and setting to work without complex test equipment and the degree of redundancy to achieve high integrity whilst avoiding conflict with reliability requirements. The hardware designed to meet these requirements will be rigourously tested to prove that the engineering approach is justified for the SM1A project. However, the paper, in drawing to a conclusion poses some of the questions which were answered in achieving a solution leaving the reader to judge if his approach would have been similar.
