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.

Simulation Software Improves Pilot Training

Providing pilots with the best possible preparation for extreme situations is the goal of new simulation software. The program that combines flow mechanics and flight dynamics in real time. The numerical model is extremely flexible and does not depend on stored flow data. External conditions such as topography, global wind speeds, and aircraft type are input. During the simulation, the algorithms use that data to continuously compute the interacting flow field at the virtual aircraft’s current location.
