Bringing RF into the Embedded World: It's Time

Embedded systems have been almost entirely digital throughout their long history, while RF and microwave technologies were separate subsystems with no effective interface between the two. For many reasons, this “RF/digital divide” should finally be connected.

Fundamental Aspects of Single Molecule and Zeptomole Electroanalysis

The objective of this research program was to provide the fundamental understanding required for using the principles of electroanalytical chemistry to detect target molecules at very low concentration, including single molecules, with high specificity, simplicity, and low power.

General Atomics Aeronautical Systems, Inc. (GA-ASI) is using an integrated fuel tank structure to maximize fuel offload for the proposed MQ-25 unmanned aerial refueling aircraft for the U.S. Navy. GA-ASI applied its knowledge of advanced composite aircraft structures to develop integrated fuel tanks in a large-scale wing box test article and a full-scale wing skin pre-production validation article.

New Products: October 2018 Aerospace & Defense Technology

Microstepping Motor Driver

US Digital (Vancouver, WA) announced the release of the MD3 Programmable Microstepping Motor Driver, capable of driving motors from NEMA size 14 to 42. The MD3 accepts 9-50 VDC power inputs and is rated for currents up to 7A continuous duty. In addition to digital input controls, the MD3 can be configured and controlled using the open MODBUS RTU protocol over a RS485 bus. A GUI application is supplied that allows many settings to be changed including the number of microsteps per full step, acceleration/deceleration rates, speed and current cutback. The design supports multiple MD3 units on the same RS485 bus and allows for programmable motion profiles. In addition, the MD3 has a brushed DC motor speed control mode.

Preventing Premature Part Failures with Electropolishing

Design engineers in the aerospace industry are constantly challenged to improve fit and function of components used in commercial and military aircraft. Parts used in these aircraft must withstand high-stress, corrosive conditions with long-term use. They also must meet highly demanding cycle life specifications.

3 Key Benefits: Better Corrosion Resistance, Fatigue Life, Part Integrity

Electropolishing has become a common metal finishing process used in the aerospace industry to help improve the overall quality of metal components. These components come in many forms including high-performance fasteners, fittings, nozzles, housings, and welded assemblies. In order to maintain reliable performance, these components must be precisely manufactured and have an impeccable surface finish that is free of burrs and other contaminants.

Advantages of Electropolishing for Penetrant Testing

It’s common, especially in the aerospace industry, for parts that are fracture critical to be Liquid Penetrant Inspected (LPI) prior to installation. Also known as Dye Penetrant Inspection (DPI) or simply Penetrant Testing (PT), this method is used to detect micro-cracks or other defects that could serve as an initiation site for failure. In order to properly execute a penetrant test, the surface of a metal part must be thoroughly clean of any debris, smeared metal, or any amorphous layer that may be hiding a hairline crack, thus yielding a false reading.

3D-Printed Turbine Extends Drone Power

A cooled, radial gas turbine was developed that provides thousands of hours of electricity to an unmanned aerial vehicle (UAV), a significant improvement to current UAV turbines that only operate a few hundred hours before wearing out.

To create the small, intricate design with internal air passages, engineers used selective laser melting, which builds metal parts layer by layer.

De-Icing Without Power or Chemicals

A buildup of ice on an airplane wing can cause catastrophic failure. But preventing that buildup usually requires energy-intensive heating systems or chemical sprays that are environmentally harmful. A new system, based on a three-layered material, collects solar radiation, converts it to heat, and spreads that heat around so that the melting is not just confined to the areas exposed directly to the sunlight.

Once applied, it requires no further action or power source. It can even do its de-icing work at night using artificial lighting. The three layers, all made of inexpensive commercially available material, are bonded together, and then bonded to the surface that needs to be protected.

NASA and Alaska Airlines Test Fuel-Saving Software

The Traffic Aware Strategic Aircrew Requests (TASAR) project, a partnership between NASA and Alaska Airlines, is testing NASA’s Traffic Aware Planner (TAP) software that merges and evaluates an unprecedented combination of real-time flight data to provide pilots with optimized flight path options.

Route optimization through TASAR offers a number of benefits, such as saving fuel and flight time, and helping pilots make better, more informed route requests to air traffic controllers. On five of its first six flights with Alaska Airlines, TAP software made reroute recommendations that reduced flight time or saved fuel, and more often than not, both.
