Microturbine Propulsion for UAVs

Seventy years ago, military aviation moved from reciprocating engines to vastly more reliable turbo jets and turboprops. Shortly after, the commercial air transport industry followed suit, enabling modern air transport. Today, virtually all large aircraft rely on turbine propulsion, yet small aircraft, both manned and unmanned, have not exploited the advantages of turbines for propulsion.

How Miniaturized Distributed Modular Architecture Advances Avionics Design

Most of today’s collision-avoidance, in-flight-entertainment (IFE), air-to-ground-communications, and other avionics systems employ electronics packaging based on the Aeronautics Radio INC (ARINC) 600 standard. Compared to the older ARINC 404 standard dating from the 1970s that defined “black box” enclosures and racks within aircraft, ARINC 600 specified a Modular Concept Unit (MCU) – the basic building block module for avionics. An ARINC 600 metal enclosure can hold up to 12 MCUs, allowing a lot of computing power to be placed in a centralized “box.” By making it possible to run numerous applications over a real-time network, ARINC 600 enabled “next generation” integrated modular avionics (IMA).

Peridynamic Modeling: An Alternative Approach to Analyzing Material Failure

A critical technology challenge for structural material applications in the aerospace and defense industries is to have a means for the reliable analysis of material damage and failure. Experimental structural assessments are typically expensive and often do not provide full information about coupled, multiscale damage processes. Computer-aided analysis has established itself as a useful tool for complementing experimental structural assessments. A comparative summary of current computer-aided approaches is presented in the accompanying table.

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).

In early 2019, the DGA (French Procurement Agency) and the French Army (STAT) organized a campaign to test the MMP land combat missile in extreme cold conditions. Performed on the Swedish state firing range at Vidsel, located near the Arctic Circle with temperatures between -15°C and -30°C, the cold weather campaign of the MMP was determined to be a complete success.
