Nano-Lubricant/Fluid for Improved Weapons System

More efficient heat removal from ground-based and airborne Army vehicles can (i) enhance the performance of these systems, particularly in hot climates; (ii) reduce the heat signature, and (iii) help reduce the weight of thermal control systems such as radiators. Building upon NEI’s nanoscale materials technologies, we propose to develop a new class of heat transfer fluid that is based on particle additives with a unique surface morphology. The Phase I program is aimed at producing stable particle-containing fluids, and demonstrating that the heat transfer properties of these fluids are significantly better than the currently used fluids (e.g. oil and grease). It is anticipated that the Nanofluid will improve power transfer and heat rejection. Specifically, a series of particle-containing fluids will be produced and tested for thermal conductivity, viscosity, and heat transfer rate. Additionally, several gallons of Nanofluids will be supplied to the Army by the end of Phase I base program. Once the proof-of-concept is demonstrated in Phase I, the technology will be implemented on a commercial scale in Phase II by meeting the performance requirements criteria specified by the Army.
