Designing Configurable Air Transport Racks

High-powered embedded computing equipment utilizing the Air Transport Rack (ATR) form factor is playing an ever-larger role in extreme, mission-critical applications in air, land, and sea environments. This compact, rugged, and light form factor has been around for nearly 70 years. Its small size meets the tight space constraints of the current generation of military grade equipment, and its flexibility, coupled with the proliferation of commercial off-the-shelf (COTS) components, allows ATR-based systems to meet cost and upgradeability goals for both legacy and emerging systems.

Designing COTS Computers for Harsh Environments

The need for commercial off the shelf (COTS) single board computer (SBC) products continues to grow as higher processing, smaller footprints and lower power requirements become more critical. For design engineers in medical, military, industrial, aeronautics and other fields, the desire for reduced size and heat also parallels an additional requirement for fanless operation. In this environment, engineers are constantly faced with the challenge of trading off various aspects of functionality to stay within a particular form factor. Finding COTS products that have all the desired characteristics and are also rated to perform in extreme harsh environments creates an additional challenge. However, there are a number of industrial grade SBC manufacturers who have been successful in designing and manufacturing COTS products specifically for use in harsh environments.

Performing Failure Mode and Effect Analysis

Failure Mode and Effect Analysis (FMEA) is a methodology for analyzing potential problems early in the product development cycle where it is easier to take action to overcome potential issues, thereby enhancing reliability through design. The tool is used to identify relationships between process and product requirements and the potential for unacceptable outputs and their effects.
