Faster power switches for aircraft safety: Going from milliseconds to microseconds - Blog

September 28, 2018
In a few milliseconds, electrical arcing in aircraft wiring can release thousands of joules of energy. This is enough to ignite wire insulation, pierce hydraulic lines, and compromise critical flight-control subsystems.

Helicopters and the kill web - Blog

September 28, 2018
WARFARE EVOLUTION BLOG: Helicopters will have a role in the kill web as they have in the kill chain dating back to their first uses in warfare. Starting with the Korean War, and later in Vietnam, the helicopter became the cavalry. Anyone serving in the Army during the 1960s and 1970s knows about the 1st Cavalry Division (Airmobile) in Vietnam. You could hear their UH-1 Iroquois helicopters (nickname: Huey) coming from miles away. These aircraft carried troops into battle and provided fire support for ground forces in a fight.

Ground combat vehicles, tanks, and the kill web - Blog

August 31, 2018
WARFARE EVOLUTION BLOG. When I started researching ground combat vehicles (GCV) and tanks, I suspected it was going to be messy from the start. I was not disappointed. There's a plethora of research reports and articles containing hundreds of pages on this topic.

Long-range bombers and the kill web - Blog

July 30, 2018
WARFARE EVOLUTION BLOG: In our last article, we examined how U.S. fighter planes fit into the kill web, along with a review of European Union (EU), Russian, and Chinese fighters. And, we looked at some of their flight characteristics and design parameters. Now, it?s time to explore long range heavy bomber aircraft.

Fighter jets and the kill web - Blog

June 28, 2018
WARFARE EVOLUTION BLOG: In the previous article, we explored the transition from the static kill chain to the dynamic kill web in future warfare scenarios. Now, let?s look at how fighter jets fit into this new model. That requires a review of the fighters being flown by the U.S. and our allies today. We also need to consider what the Russians and the Chinese are doing with their fighter jets.

Expand your imagination with the surprising versatility of MIL-DTL-38999 circular connectors - Blog

May 30, 2018
Introduced in the 1970s and still widely used today, MIL-DTL-38999 circular crimp connectors are sometimes taken for granted. Their long history and general popularity make it easy to overlook the ability of the broad 38999-connector family to help engineers solve contemporary size, weight, and power (SWaP) challenges. In fact, the 38999-connector family continues to adapt new composite materials and form factors to meet demanding weight and size requirements, while design derivatives have evolved to support higher speeds and higher frequencies in this surprisingly versatile I/O connector family.

Transitioning from the kill chain to the kill web - Blog

May 30, 2018
WARFARE EVOLUTION BLOG: My last post outlined the strategic reviews and national defense priorities that sit on top of the kill chain. Defense planners at the Defense Advanced Research Projects Agency (DARPA) are now looking at transitioning to a concept they've dubbed the kill web.

Integrating warfare models with the kill chain - Blog

April 27, 2018
WARFARE EVOLUTION BLOG: My previous article covered what sits on top of the kill chain from a strategic perspective. Now, it?s time to integrate the other models: RMAs (revolutions in military affairs), warfare domains (land, sea, air, space, cyberspace, electromagnetic (EM) spectrum), strategic offsets, generations of warfare (1GW through 8GW), and the OODA loop (Observe, Orient, Decide, and Act).

Higher-density RF is on your radar with VITA 67.3 standard - Blog

March 29, 2018
These days, multifunction radars handle functions from surveillance to jamming to fire control, and can track multiple targets in both short- and long-range threats. That means one thing for your active electronically scanned array (AESA) radar design--you need a lot more signal processing power.

VPX power supplies and EMI filters - Blog

March 22, 2018
Electro-magnetic interference (EMI) filters are critical components in any electrical design, especially in support of military systems requiring partial or complete qualification to MIL-STD-461. EMI filters are designed to reduce high frequency conducted and radiated electronic noise which may create interference with other electrical devices. Embedding EMI filters into the power supply, a potential signal source, is a key feature in any power supply design.

MIL-STD-1553: Do we know too much - or too little? - Blog

February 28, 2018
MIL-STD-1553 is a very tried and true, well known, serial interface for the space and aviation industry that was originally developed for critical avionics interfaces that were required to solve the problem of connecting the many sensors and controls around an aircraft and relaying information between them and the crew. Key requirements are that information is transmitted reliably and in a timely manner.

Mezzanine modules benefits & comparisons - Blog

February 27, 2018
Open architecture embedded systems for military/aerospace applications have always relied on mezzanine or daughter cards to provide flexibility and modularity because they are very effective in handling the large variety of I/O functions required. Thanks to widespread adoption of industry standards defining these mezzanine products, carrier boards are able to accept mezzanine boards from a wide range of vendors, each specializing in niche technologies and interfaces.
