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.

Beyond VMEbus A New Concept

Deployability and life-cycle management of large and disparate collections of weapons, combat and C4ISR computing systems is one of the most critical challenges facing the Department of Defense today. Numerous defense programs, each defining separate, and oftentimes unique system architectures, configurations, and compositions, result in a wide range of processing and control systems that create complexity and drive excessive lifecycle costs.

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.

Surviving the Challenge of Thermal Design in Aerospace Electronics

The aerospace sector places some uniquely challenging demands on electronics designers. For a start, the environments that the electronics are exposed to are much harsher than in almost every other scenario. Moreover, the life expectancy of the products is much higher, while the accepted failure rate is easily an order of magnitude lower than typical commercial products.

New Technologies Tackle UAV Challenges

Unmanned vehicles for air, land, and water represent an increasingly-important capability for virtually all military services worldwide. Because each new generation of device technology promises capabilities and higher levels of overall performance for unmanned vehicles of all types, military customers expect these benefits in the latest UAV offerings. To meet these expectations, systems engineers must deal with increasingly difficult problems of thermal management, power budgeting, EMI emissions and susceptibility, weight, size, cabling, connectors, antenna management, and command/control functions. Several new technologies and innovative packaging concepts now provide better solutions to these issues.

Protecting Critical Data on Unmanned Underwater Platforms

Emerging mission requirements from global defense forces are driving new programs and applications for Unmanned Underwater Vehicle (UUV) platforms. Like their airborne counterparts, UUVs are ideal for deploying Intelligence, Surveillance and Reconnaissance (ISR) mission payloads. To speed the development of these autonomous vehicles, system designers are turning to small form factor (SFF) Commercial off the Shelf (COTS) technologies previously proven in Unmanned Aerial System (UAS) deployments. These low-power SFF subsystems, including miniature network switches and mission computers, are ideal for use in UUVs for which any additional weight or power consumption can have significant detrimental effects on mission distance and duration. By selecting proven rugged COTS solutions, already tested and qualified to the extreme demands of MIL-STD-810G, MIL-STD-461, MIL-STD-704 and/ or RTCA/DO-160G standards for environmental, power, and EMI compliance, UUV system developers have found that they can greatly accelerate their program integration and reduce overall risk.

Educating UGVs

Advancements in the field of artificial intelligence (AI) are accelerating as the technology matures from being research-orientated to being deployed in a wide range of products and services, such as autonomous vehicles. While Convolutional Neural Networks (CNNs) were first described in the 1950s, the technology remained an academic concept until the availability of large training data sets and powerful Graphics Processor Units (GPUs), a processor architecture ideal for the heavy math computational demands associated with neural network processing. Once scientists had low-cost and high-performance platforms, the technology exploded for many commercial uses. Military use is more challenging due to the lack of large data sets, but that is changing too as areas including thermal imagery are starting to be used.
