SDR Interface for the NeXtRAD Multistatic Radar System

Aerospace & Defense Technology: December 2019

  • Magazine Article
  • 19AERP12_06
Published 2019-12-01 by SAE International in United States

NeXtRAD is a dual-band, dual-polarization, multistatic radar system under development at the University of Cape Town (UCT) in col lab oration with University College London (UCL). The primary mission of the system is to collect multistatic data of small radar cross-section maritime targets embedded in sea clutter.

Experimental and Numerical Investigations of the Early Flame Development Produced by a Corona Igniter

Università degli Studi di Perugia-Federico Ricci, Jacopo Zembi, Michele Battistoni, Carlo Grimaldi, Gabriele Discepoli, Luca Petrucci
Published 2019-10-07 by SAE International in United States
In order to reduce engine emissions and fuel consumption, extensive research efforts are being devoted to develop innovative ignition devices, able to extend the stable engine operating range towards increasing lean conditions. Among these, radio frequency corona ignition systems, which produce a strong electric field at a frequency of about 1 MHz, can create discharges characterized by simultaneous thermal and kinetic effects. These devices can considerably increase the early flame growth speed, initiating the combustion process in a wide region, as opposed to the local ignition generated by traditional sparks. To explore the corona ignition behavior, experimental campaigns were carried out to investigate different operating conditions, in a constant volume calorimeter designed to measure the deposited thermal energy. The present work compares the combustion development generated by a traditional spark and the corona igniter through computational fluid dynamics simulations. First, simulations are carried out to reproduce the experimental results in the calorimeter, comparing the measured and predicted pressure traces in an inert environment. The validated approach is then applied in a second step to the…

General Requirements for Powered Drive Units (PDUs) in Aircraft Cargo Systems

AGE-2 Air Cargo
  • Aerospace Standard
  • AIR4165B
  • Current
Published 2019-10-02 by SAE International in United States
This SAE Aerospace Information Report (AIR) is intended to assist the user (aircraft manufacturer/airline) in the following areas: a In the decision of whether or not to plan for the installation of a powered drive system in the cargo loading system (CLS) during the definition of the aircraft on-board cargo loading system. b If a powered drive system is decided upon, to provide general requirements to be considered during the preparation of component specifications for the powered drive units (PDUs) to be used. This provides a selection of criteria in order to obtain an optimum PDU for the application considered.

Wireless Transceiver Quadruples Speed of 5G

  • Magazine Article
  • TBMG-35268
Published 2019-10-01 by Tech Briefs Media Group in United States

A new wireless transceiver was developed that boosts radio frequencies into 100-gigahertz territory, which is quadruple the speed of the upcoming 5G, or fifth-generation, wireless communications standard. The end-to-end transmitter-receiver is a 4.4-millimeter-square silicon chip capable of processing digital signals significantly faster and more energy-efficiently because of its digital-analog architecture. Having transmitters and receivers that can handle high-frequency data communications is vital for Internet of Things devices, autonomous vehicles, and vastly expanded broadband for streaming of high-definition video content and more.

Technique Locates Robots and Humans in GPS-Challenged Environments

  • Magazine Article
  • TBMG-35278
Published 2019-10-01 by Tech Briefs Media Group in United States

An algorithm enables localization of humans and robots in areas where GPS is unavailable. The Army needs to be able to localize agents operating in physically complex, unknown, and infrastructure-poor environments. This capability is critical to help find dismounted soldiers and for humans and robotic agents to team together effectively.

Solid-State Microwave Power Module

  • Magazine Article
  • TBMG-35350
Published 2019-10-01 by Tech Briefs Media Group in United States

Historically, the term microwave power module (MPM) has been associated with a small, fully integrated, self-contained radio frequency (RF) amplifier that combines both solid-state and microwave vacuum electronics technologies. Typically, the output power of these MPMs is on the order of about 100 Watts CW over an octave bandwidth. Because of their smaller size and lower mass compared to conventional traveling-wave tube amplifiers, these MPMs may have applications in electronic warfare systems.
