Pin Fin Heat Sinks

Advanced Thermal Solutions, Inc. (ATS) (Norwood, MA) has a family of Pin Fin heat sinks designed as cost-effective solutions for systems with adequate airflow. The high aspect ratio design enables ATS Pin Fin heat sinks to provide low thermal resistance from base to fins in systems where the airflow measures 200-plus LFM (linear feet per minute). The cross-cut design also allows the Pin Fin heat sinks to be effective in systems where airflow is ambiguous.

High-Performance Computing for the Next-Generation Combat Vehicle

The development of the Next-Generation Combat Vehicle (NGCV) will require technological advancements in many areas, including lethality, protection, autonomy, human–agent teaming, and electromagnetic capabilities. What ties all of these future capabilities together is the need for vast computational resources to support the artificial intelligence (AI) implicit in bringing these advancements to the battlefield. The operating environment of the NGCV will be such that communications will be severely limited, if available at all; systems will be under constant cyber-attack; and adversarial AI may be actively attempting to deceive all sensors — all occurring under severe size, weight, power, and time-available constraints. These factors, and more, are the motivation for developing a strategy of mobile High-Performance Computing (HPC) for the NGCV.

Using Thermoplastics in Aerospace Applications

In August 2017, Qantas Airlines laid down the challenge to both Boeing and Airbus to offer an aircraft that can cross one of aviation's “last frontiers.” That “last frontier” was an aircraft capable of flying an economical passenger load non-stop for over 20 hours. This would allow Qantas to offer direct service from Sydney to London or New York. Weight reduction through the use of thermoplastics and other technologies would be the key to any chance of success in this endeavor.

Taming the Thermal Behavior of Solid-State Military Lasers

Laser diodes and laser diode arrays (LDAs) are widely used throughout military systems, for sighting and range finding, but also at high power levels as offensive and defensive weapons. In companion with much higher-power chemical lasers, these high-power optical sources can generate kilowatts of optical power (as arrays) for use in neutralizing incoming missiles, rockets, and armaments and for long-distance offensive strikes. But laser diodes are also still inefficient, and a great deal of the energy supplied to a laser diode or an LDA is converted into heat, which must be safely dissipated to ensure a long operating lifetime for the solid-state devices.
