Cooling Your Embedded System: What Can Your Open Standard Architecture Handle?

Embedded computing systems for Mil/Aero applications are often conduction-cooled in an ATR or nonstandard chassis. However, there are many designs that require 19" rackmount systems with forced-air cooling. As more processing performance is packed into tight spaces, enclosures that provide advanced cooling options are increasingly common.

Evaluating Key Certification Aspects of Multicore Platforms for Safety Critical Avionics Applications

High performance, low power consumption and small footprint requirements imposed by the embedded market on the processor industry is causing a definite move away from single-core processors to multicore processors. Multicore processors have been deemed as the future of Size, Weight, and Power (SWaP) constrained applications like military and avionics. They provide higher performance (MHz/W) at lower power. They also allow consolidation of multiple functions/ applications onto a single platform.

Simulating and Analyzing Flow for an Air-to-Air Refueling System

Long-range bombers may have missions halfway around the world. Fighter jets may have to stay in the air longer than their relatively small fuel tanks will allow, or may find they have exhausted their fuel unexpectedly, such as during supersonic flight or evasive maneuvers. In these situations, large tanker aircraft are deployed that carry sufficient fuel to refill several smaller aircraft in a single mission (Figure 1). The task of injecting volatile jet fuel from one aircraft to another while both are moving at high speed and altitude is fraught with risk.

The Ins and Outs of Spaceflight Passive Components and Assemblies

RF and microwave components deployed in spaceflight applications can experience hundreds of degrees of temperature variation, massive amounts of radiation, and can be expected to operate at an elevated level, sometimes for decades. The demands of operating in a space environment bring unique challenges and unforgiving reliability requirements. Designing passive components to meet these rigorous operation criteria necessitates a high level of design expertise, qualifications/certifications, and testing capability.

Army Demonstrates Hoverbike Prototype

A JTARV Model P-200 is demonstrated. (U.S. Army photo: Jhi Scott) The US Army demonstrated the flying capabilities of a unique rectangular-shaped quadcopter. The Joint Tactical Aerial Resupply Vehicle (JTARV), also known as a hoverbike, may one day make it possible for soldiers on the battlefield to order resupply and then receive those supplies rapidly.
