The “So what” of TDS...

What started out as a government funded research project has blossomed into a commercial product unlike anything on the market. Thermal Defense Solutions,LLC is proud to partner with Oak Ridge National Laboratory (ORNL) in an exclusive licence agreement to offer you (the public) the most technologically sophisticated suppressors on the market.

“ORNL teamed with US SOCOM, US ARMY ARDEC, and Lawrence Livermore National Laboratory (LLNL) between 2008 and 2014 to develop a model-based design code to simulate the phenomenon occurring inside weapons suppressors. This allows the researchers to understand what is really happening inside suppressors, allowing better designs and more functional weapons platforms. These high fidelity codes run on high performance multi-processor computers. These computers were used to determine how the gas flows from the muzzle to the exit of the suppressor, while reducing the pressure. By manipulating the interior structure of the suppressor, and moving away from a traditional baffle design, we were able to design the system to change the rate of flow of the gas exiting the suppressor before and after the bullet. By stretching the time it takes the gas in the suppressor to vent from the initial pressurization, we minimize the acoustic signature. But by allowing a flow through system that allows the gas to move through the suppressor, we allow the suppressor to depressurize faster than a traditional baffle device, thus minimizing the time the hot gases are held in the suppressor, thus reducing temperatures by nearly half that of a traditional baffle design. In addition, this depressurization allows for a significantly reduced back pressure on the weapon, minimizing added failures typically seen, but also minimizing the combustion gases blown back in the operators face. Last, the super computers used to model the system allowed for precise placement of the venting of the gases, to allow acoustic wave sharpening, thus allowing the designer to use destructive interference of the acoustic waves to minimize sound, and produce a suppressor with enhanced acoustics, while at the same time reducing temperatures, back pressure, and flash. While other traditional baffle designs can be made to be very good in acoustics, or flash, or weight, making a suppressor that is excellent in all categories is unique, and thus these are the most advanced suppressor designs.

During the program, the team designed a suppressor for a belt fed weapon that can reduce the extreme temperatures of sustained fire situations on the Mk48 weapon platform. Several designs were shown to have significantly better acoustic report than OEM suppressors, as well as nearly zero flash and a 60% reduction in heat buildup in the device.

ORNL has transitioned technology that it developed during the SOCOM program to a company called Thermal Defense Solutions, Inc. These two designs were optimized using the 3-D model codes, and 3-D printed from Inconel 718. When compared to a standard OEM suppressor typically used by the military, the ORNL designs were superior on several fronts: 1) acoustics, 2) heat buildup, 3) back pressure, and 4) flash. In addition, the reduced backpressure results in no noticeable change in speed of the bolt carrier, thus no added stress on secondary parts. The data presented here are those tested by ORNL. Thermal Defense Solutions has tested and reported data for their optimized designs.” –James W.
