Design Features of Small Brayton Cycles for Autonomous Underwater Vehicles.

Abstract

Several alternative power systems are being considered for small autonomous submersibles to meet long duration and high speed operations. The closed cycle Brayton engine using lithium sulfur hexafluoride as the energy source is one of the more promising systems. A small closed cycle Brayton engine has been evaluated utilizing components which have been tested for space applications. Modifications were made to optimize the unit for the undersea vehicle. Computer programs were developed to facilitate this process. It was concluded that a 2 kilowatt Brayton cycle engine would occupy 50 inches of length in a 21 inch diameter space and 36 inches in a 25 inch diameter space.
