Air-Ground Communications System Aims to Make Flying Safer

Reliance on old-fashioned radio contact by pilots and vulnerable tracking systems is still high, but satellites are set to change sky safety, thanks to international collaboration. The European Space Agency’s Iris program is looking to satellites to make aviation safer through modern communications. Worldwide digital data links via satellite, offering much higher capacity, will become the standard for cockpit crews, with voice communications kept as backup.

COTS Rugged Systems

North Atlantic Industries
Bohemia, NY
631-567-1100
www.naii.com

North Atlantic Industries (NAI) recently received an initial contract from L-3 Maritime Systems for Custom-on-Standard Architecture™ (COSA™) COTS rugged systems for the Ship to Shore Connector (SSC) Data Acquisition Unit. The advanced, rugged intelligent I/O and communications subsystem delivers significant advantages for data acquisition and control solutions for the U.S. Navy’s new SSC program. The SSC is the successor to the Navy’s versatile Landing Craft Air Cushion (LCAC) vehicle, which is nearing its expected service life. Prime contractor for the detail design and construction of the Ship to Shore Connector, awarded under Naval Sea Systems Command (NAVSEA) Contract N00024-12-C-2401, is Textron Systems.

Fabricating Transparent and Stretchable Supercapacitors Based on Wrinkled Graphene Electrodes

Stretchable electronic devices, including solar cells, light-emitting diodes, batteries, and textile supercapacitors, have been developed to retain their functions even when under large strains (up to 40%). Some transparent solar cells, batteries, and supercapacitors have also been developed. However, most of the currently developed electrodes and the associated supercapacitor cells cannot be both transparent and stretchable.

Modular Exhaust Design and Manufacturing Techniques for Build-to-Order Muffler Systems

Managing the acoustic signature of military vehicles can play a critical role in the safety of soldiers. Low-frequency sounds propagate through the atmosphere, resulting in unacceptable acoustic vehicle detection ranges, requiring relatively large silencer structures to mitigate. Currently, these requirements are met by using a custom muffler that is hand-assembled using low-volume prototyping manufacturing techniques. This method results in significant engineering and manufacturing time.

Silicon Microsphere Fabrication

The efficiency and methodology of coupling light into microcavities has improved exponentially in the last decade. One such advancement is coupling light onto silicon microspheres. The material, size, and shape of a silicon microsphere are ideal for optical devices. Silicon microspheres are not the primary material used to fabricate microspheres for optical coupling because current methods used for microsphere fabrication cannot produce single-crystal silicon in the 16-μm scale, which is best for current optical technology.

Designing and Fabricating a Multiple-Decade Battery

There is a great need for energy sources that can power unattended sensors for more than a decade. Unattended sensors can be located in harsh and remote locations that are often dangerous for personnel maintenance and power source replacement. The power source must last the lifetime of the sensor. Unlike chemical batteries, the higher energy densities of radioisotopes allow the sensors to operate for infrastructure lifetimes (~150 years). Isotope batteries (iBATs) have the potential to become reliable, robust, and maintenance-free power sources for remote, long-term, low-power sensors. iBATs are different from chemical batteries because they are self-contained energy sources using radioisotope decay.
