The design features of the FT12 gas turbine are described. The development background of the gas turbine is reviewed along with service-experience background which, with appropriate marinizing treatments, prompted evaluating the gas turbine in a sea-borne environment. The program conducted in an LCM-8 landing craft, its highlights and results are discussed.

The design features of the FT12 gas turbine are described. The development back-ground of the gas turbine is reviewed along with service-experience background which, with appropriate marinizing treatments, prompted evaluating the gas turbine in a seaborne environment. The program conducted in an LCM-8 landing craft, its highlights and results are discussed.

The major design features of the FT4A gas-turbine engine for marine and industrial applications are described, the development-test history of the engine is reviewed, and the field experience with this and similar engine concepts is discussed. In addition, the particular characteristics of the FT4A power plant which make the latter attractive for various applications are mentioned.

This paper is a continuation of a previously presented paper, which described the over-all design of the major components of a mobile power unit. The present paper is concerned with the main power equipment only and offers a detailed description of the design features which were developed for this project and also provide the flexibility necessary to make this gas turbine suitable for other applications.

The impact of potential aviation gas turbine fuels available in the near to midterm, is reviewed with particular reference to the small aviation gas turbine engine. The future course of gas turbine combustion R&D, and the probable need for compromise in fuels and engine technology, is also discussed. Operating experience to date on Pratt & Whitney Aircraft of Canada PT6 engines, with fuels not currently considered of aviation quality, is reported.

This paper discusses the use of 570/571-KF engine in patrol boat propulsion applications. The text is composed of two basic sections — 1. The Engine, and 2. The Applications: The engine section includes a brief review of the background and development of this free turbine engine, as well as a description of the main components and design features. The performance characteristics and fuel consumption rates are discussed relative to patrol missions. In the applications section a comparison is made of the current 570 installations (both civil and military), along with a survey of the planned applications. Finally a review of proposed uses of these engines in other naval vessels is included to show the adaptability of this size engine in FPB and PB missions, and demonstrate the feasibility of retrofitting other turbine or diesel powered patrol boats with 570/571-KF engines. The conclusion is drawn that for patrol boats with conventional or modified hull forms, the Allison 570/571 engines are well suited due to their excellent performance and power density ratios.

The S.S.S. (Synchro-Self-Shifting) overrunning clutch with its pawl actuated helical sliding motion is well known, particularly in the gas turbine field. This paper reviews briefly the clutch operating principle, then outlines some of the service experience since 1958 in naval main propulsion drives in COSOS, COSAG, CODOG, CODAG and COGOG plant. Extra features are then described such as a lock-out control as is usually necessary for turbine applications to permit turbine testing, e.g., when in harbor; also a lock-in control as is essential when the clutch has to transmit power in both directions of rotation. Various clutch mounting respective advantages. The paper concludes with information regarding reliability during many years of service experience.
