U.S. Army TARDEC Fuels and Lubricants Research

For more than 50 years, the U.S. Army TARDEC Fuels and Lubricants Research Facility (TFLRF) at Southwest Research Institute® (SwRI®) has provided state-of-the-art research, development and engineering services for the U.S. Army’s fuels and lubricants needs. The government-owned contractor-operated (GOCO) facility provides technical support services and helps to develop and maintain the Army’s specifications for fluids used in ground equipment. TFLRF functions as an extension of the U.S. Army Automotive and Armaments Command (TACOM) Petroleum and Water Business Area in Warren, Mich. Operated by the Fuels and Lubricants Research Division on the grounds of Southwest Research Institute in San Antonio, Texas, the facility reports to the U.S. Army Tank Automotive Research, Development and Engineering Center (TARDEC) in Warren, Mich.

The U.S. Army built the facility at SwRI as a stand-alone laboratory complex with capabilities for engine testing and analytical chemistry experiments. The Armed Services’ need for engineering support in fuels and lubricants for their growing fleet of military vehicles and related ground support equipment was the impetus for establishing the facility. The capabilities parallel, on a smaller scale, the commercial capabilities available at SwRI. As the partnership between the Army and SwRI evolved, the Army increasingly has depended on the Institute’s commercial facilities for the more standardized evaluations, and the TFLRF has become more focused on custom projects.


Since 1949, Southwest Research Institute has been engaged in automotive-related research and has become a recognized global leader in automotive research and development for both government and industrial clients.


The facility is a unique resource where a highly trained and experienced staff perform integrated fuels, lubricants and engine systems research and development programs involving combustion, performance characterization, engine cleanliness, vulnerability assessments and tribology. Augmented by the Institute’s diverse workforce of more than 3,300 and its facilities, which includes more than 2 million square feet of laboratories and offices on more than 1,200 acres, TFLRF’s capabilities range from fundamental investigations to field-validating testing and rapid response problem solving.

Efforts early on by the TFLRF led to changes and developments of new procedures and requirements subsequently adopted by commercial industry. Those initial results from the partnership included:

  • Identifying causes and chemistry of engine sludge and deposit formation
  • Developing a fundamental understanding of low temperature wax formation in diesel fuels
  • Analyzing engine exhaust emissions
  • Understanding diesel ignition and combustion
  • Evaluating fuel alternatives for spark ignition and diesel engines
 

For more than 50 years, the U.S. Army TARDEC Fuels and Lubricants Research Facility (TFLRF) has provided state-of-the-art research, development and engineering services for the U.S. Army’s fuels and lubricants needs.



The U.S. Army TARDEC Fuels and Lubricants Research Facility on the SwRI grounds is a government-owned, contractor-operated facility.



 

 

More recent projects include:

  • Development and fielding a fire-resistant JP-8 fuel for Army ground combat and tactical equipment that will self-extinguish, helping to save lives, reduce severe burns and minimize equipment loss by fire
  • Support for a project for the Defense Advanced Research Projects Agency to qualify jet fuels made from non-petroleum sources
  • Evaluating a variety of oil lifetime extension approaches for Army ground vehicles
  • Conducting a study to assess the feasibility of a single-specification, single-viscosity grade lubricant for military ground vehicles

Turbine Combustion Facility

TFLRF houses a unique turbine combustion capability that has been sized around the Army T-63 gas turbine engine. This facility:

  • Supports turbine combustion research focused on fuel impacts on emissions and combustion system component durability
  • Simulates the combustion section of the T-63 or other small gas turbines, or can run sectors from larger engines

In a demonstration of a potential fire-resistant fuel, following ignition, the fuel sample in a barrel located in the enclosure contained a suppressant that helped to extinguish the fire.


An outgrowth from the combustor work is a series of benchscale facilities for assessing the formation of fuel-derived deposits on turbine engine atomizers and other fuel system components. Because fuel-derived deposits are the leading cause of turbine engine overhaul, the facility has developed a number of techniques to assess the propensity of fuels to form deposits and to evaluate engine hardware for deposition tendencies. In addition to gasoline engine test stands, the TFLRF houses a number of diesel fuel injection system test stands to evaluate the impact of the following on injection system wear:

  • Low lubricity fuels
  • Fuel additives
  • Alternative fuel formulations

Lubricity and Filtration Studies on Diesel Systems

Using a number of bench-wear test devices as well as full-scale engine hardware, the laboratory is continuing to conduct research on fuel lubricity and other fuel issues affecting diesel fuel injection system durability. Fluid filtration is becoming increasingly critical to engine durability as a result of high-pressure injection systems. Filtration for both ground and aviation vehicle systems is particularly critical for military operations in high dust environments. The TFLRF facility maintains capabilities for assessing the performance of fuel filters and water separators, including an SwRI-owned facility for assessing pipeline scale filtration performance.


Turbine combustion research is focused on fuel impacts on emissions and combustion system component durability.


In the area of fluids filtration, capabilities include:

  • Fluid mechanics
  • Heat transfer
  • Sensor development
  • Liquid filtration
  • Contamination control and identification
  • Fuel and water logistics
  • Chemometric methods of analysis
  • Test methods development
