Advanced low heat rejection (lhr) engine life expectancy has been limited almost entirely by performance of the liquid lubricant component of the tribology system. the advanced integrated propulsion system (aips) diesel engine is a leading candidate for the army's block iii engine, to be used in the… More

Maintenance of Air Force turbine engines is hampered by threaded fasteners which have seized and cannot be removed, particularly in high-temperature turbine sections. Removal of these fasteners for routine maintenance often results in galled, seized or broken parts, with accompanying damage to the… More

Improvements in liquid lubricant performacne and life are required for the AIPS advanced military diesel engine. At the 340 degree F oil sump temperature of this engine, the antiwear/anti-oxidant additives in most AIPS candidate lubricants are rapidly decomposed. Several additive functions are thus… More

The objective of this program is to develop an integrated tribology system for advanced low heat rejection (LHR) diesel engines. The system will consist of a substantially improved high-temperature liquid lubricant, for long life under severe conditions; improved compatible engine tribomaterials;… More

The objective of this program is to develop an advanced tribology system for the next generation of high-output, low heat rejection (LHR) diesel engines. Engines for the U.S. Army Future Combat System will operate at significantly higher temperatures than today's prototype LHR engines. Surfaces… More

The objective of this program is to develop an extreme-temperature lubricant for the U.S. Army Future Combat System (FCS) propulsion system. The system will operate at significantly higher temperatures for longer durations than today's prototype low heatrejection (LHR) diesel engines. The lubricant… More

"Surfaces Research is developing multigrade (15W40) extreme-temperature engine oils that provide superior performance and single-fluid logistic advantages for the U.S.Army Future Combat System (FCS) engine.The FCS engine operates at significantly higher temperatures for longer times than previous… More

Surfaces Research proposes development of an innovative new extreme-temperature engine lubricant. We propose a high-temperature multicylinder engine test of the lubricant in a Surfaces Research engine operating at Future Combat System (FCS) conditions. Thenew lubricant has exceedingly long useful… More

Surfaces Research proposes optimization and engine endurance demonstration of an innovative tribology system for Future Combat System (FCS) diesel engines. Our new extreme-temperature engine lubricant and self-lubricating cylinder liner coatings will be evaluated in NATO-cycle endurance testing. … More

The team of Surfaces Research and the University of Florida proposes to study novel ionic liquids as lubricants for space mechanisms, MEMS devices, and electrical contacts. Ionic liquids offer unique properties of great interest to the U.S. Air Force, including ultra-low vapor pressures, extremely… More

Army vehicles require aggressive protection from rust and corrosion during long-term storage. MIL-PRF-21260 specifies a preservative/break-in oil to preserve a vehicle engine for an indefinite storage period, then drive it into service. MIL-PRF-2104 specifies a separate engine oil for in-service… More

Surfaces Research proposes development of a highly durable solid lubricant coating to eliminate wear and vibration problems in liquid hydrogen turbopump gears. The cryogenic turbopumps are used in rocket engines for Air Force expendable launch vehicles. Our new coating will exceed the cryopump… More

The U.S. Navy is seeking innovative concepts to substantially improve life of grease-packed hanger bearings on the tilt-rotor V-22 Osprey aircraft. Hanger bearings are especially maintenance-intensive and short-lived. Extending maintenance intervals and increasing bearing life several-fold are goals… More

Surfaces Research proposes a Phase II STTR program to conduct further research with ionic liquid lubricants based upon our successful Phase I research. We have assembled a team for fundamental surface science and chemistry, tribology, microtribology, and molecular modeling to conduct this research.… More

Surfaces Research is developing a top-treat to enhance MIL-PRF-2104 diesel engine oil with additional preservative properties of MIL-PRF-21260E. There are many logistic and economical advantages to the Army with this single oil approach. Our lubricant effectively eliminates preservative oil… More

The U.S. Navy is pursuing innovative concepts to substantially improve life of grease-packed hanger bearings on the tilt-rotor V-22 Osprey aircraft. In our successful Phase I program, we developed and demonstrated greases with performance far superior to current MIL-PRF-81322 grease over a wide… More
