Shape-Shifting Origami Could Help Antenna Systems Adapt On-the-Fly

Conventional reconfigurable electrical and radio frequency (RF) structures commonly used in applications involving real-time reconfigurability in response to fast varying operational scenarios require specialized substrates or complex electrical circuits. Origami-based RF reconfigurable components and modules offer a solution with unique properties. First, they enable re-configurability over continuous-state ranges (as opposed to discrete states). Second, they do not require specialized mechanical support for multilayer frequency-selective surface structures. Moreover, deployable origami-based RF structures can achieve large surface re-configurability ratios from folded to unfolded states. Finally, these structures allow for independent control of multiple figures of merit: bandwidth, frequency of operation, and angle of incidence.

Operational Considerations for High-Reliability Interconnects in Military and Aerospace Applications

In the recent past, military acquisition has shifted from being locked into large long-term contracts to developing complex systems in discrete increments that can be further optimized in future design cycles. These shorter design cycles allow for equipment to be deployed more rapidly, thereby mitigating the risk of subsystems going obsolete as increasing proportions of budget dollars go towards operation and support (O&S). This transition to evolutionary acquisition (EA) leaves a major opportunity for vendors to develop commercial off-the-shelf (COTS) components that are military-compliant.

Critical Communications Break Out of the Analog Mold

Once firmly rooted in its analog origins, critical communications is now steadily evolving to provide enhanced situational awareness. The latest public safety and military communications (MilCom) radios are more versatile and reliable, supporting ad-hoc networks to improve or enable connectivity. With higher-data-rate capabilities, critical communications solutions can send and receive high-resolution images, videos, and other types of data-intensive content. At the same time, they provide higher-quality voice communications while maintaining security. To ensure communications and interoperability, they still can support analog communications as a failsafe. These myriad capabilities are possible through the ongoing adoption of new technologies, ranging from digital public safety standards and modulation formats, to technologies like wireless local area networking (WLAN) and Long Term Evolution (LTE).

Mine Roller

Rostec State Corporation
Moscow, Russia
+7 (495) 287-25-25
https://rostec.ru/en/

Chelyabinsk Tractor Plant, part of UralVagonZavod Group belonging to Rostec State Corporation, has developed a mine roller to be installed on "ironclads” — models B10M2S and B12S armored tractors. The B10M2S is an armored bulldozer designed and built by Company Uralvagonzavod (UVZ), a subsidiary of Rostec State Corporation. The bulldozer, which has a maximum weight of 22,800 kg (50,265 lbs), is powered by a 190 hp YaMZ-236 diesel engine, giving it a top speed of 11 km/h (6.8 mph). Tractors with a mine roller are more maneuverable than mine-clearing tanks and have a longer service life, which makes them optimal for humanitarian demining. Production of a prototype mine-clearing tank was scheduled to begin in the first quarter of 2019.
