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.

Validation of Ubiquitous 2D Radar

Seastema SpA, a company owned by Fincantieri (Genova, Italy), designs, develops, and supplies integrated automation systems for different areas of the marine industry. The company established an Innovation Division in Rome to verify the feasibility of an unconventional radar system by means of a demonstrator built as much as possible with commercial off-the-shelf (COTS) devices.

New Pulse Analysis Techniques for Radar and EW

Pulsed signals are widespread in radar and other electronic warfare (EW) applications, and they must be accurately measured for manufacturing, design of countermeasures, and threat assessment; however, pulse measurements are an especially challenging area for signal analysis due to these factors:

How Additive Manufacturing is Changing the Aerospace Industry

Additive manufacturing was invented more than 30 years ago and, from small beginnings in prototyping, has developed and grown into a $6 billion industry. While additive manufacturing for aerospace and defense has seen slower adoption than some other industries, the velocity is now visibly increasing. This has been enabled by the ongoing development of additive technologies that apply more increasingly to aerospace and defense -namely better plastics materials, faster 3D printing technologies, focused development of metals materials, and resulting technologies and processes that are increasingly easier to get qualified.
