This paper aims to describe very briefly the Rolls-Royce 18 MW SM1C Marine Spey gas turbine, 1, and then to show how intercooling and regeneration could be added to increase its power to about 22 MW, with an associated increase in thermal efficiency to about 43%. As the SM1C based ''ICR'' unit is still very much in the infancy of its design, this paper does not discuss the design in detail; indeed, the details are certainly not all within the Rolls-Royce design sphere, as the Allison Gas Turbine Division of General Motors Corporation and Garrett AiResearch are partners of Rolls-Royce Limited and Rolls-Royce Inc. in the project. The broad principles of the improved cycle are described and then the effects of the use of such a unit on the operational characteristics of warships are discussed, comparing them with those of warships using simple cycle Spey SM1C units in different installation configurations.
