Turbine propulsion for heavy armored vehicles

Duffy, R.J. / Hower, G.K.

Propulsion system selection for armored tracked vehicles is driven by considerations of low volume, high fuel efficiency and affordable life cycle cost. In this context, a turbine powered propulsion system offers significant advantages for future heavy armored vehicles. Because of its high power density, an advanced technology turbine engine, in an integrated propulsion system, offers significant volume reduction over today's turbine and diesel propulsion systems. Improvements in turbine component design and cycle temperature capability provide high fuel economy. An aggressive Design-to-Cost Program and careful attention to RAM-D during development allow acquisition and Life Cycle Cost goals to be achieved. This paper details an approach to design selection and demonstration of an advanced technology recuperated turbine engine for a heavy armored tracked vehicle. Also included is a description of innovative design features to achieve cost and performance goals. Examples of payoff from Design-to-Cost/RAM-D efforts applied during the demonstrator effort are also included. The current status of the demonstration effort is presented.
