Outsourcing Plasma Treatments for Surface Modification

Aerospace & Defense Technology: February 2020

  • Magazine Article
  • 20AERP02_02
Published 2020-02-01 by SAE International in United States

In manufacturing, plasma treatments are often utilized to solve problems that cannot be resolved other ways. Whether attempting to improve adhesion of dissimilar materials; depositing coatings; cleaning surfaces; applying a protective coating that repels water, for example, or biological fluids; or enhancing surface wettability or functional coating, plasma treatments often add significant value to products.

A New Network Design for the “Internet from Space”

Aerospace & Defense Technology: February 2020

  • Magazine Article
  • 20AERP02_06
Published 2020-02-01 by SAE International in United States

Satellites do not yet play a major role in the world's Internet infrastructure; however, this may soon change. Within the next decade, a new generation of satellites could lay the foundations for an “Internet from space,” according to Ankit Singla, a professor at ETH Zurich's Network Design & Architecture Lab. His team is investigating how to improve the performance of large-scale computer networks including the Internet.

Implementing an Aerospace Factory OF THE FUTURE

Aerospace & Defense Technology: February 2020

  • Magazine Article
  • 20AERP02_04
Published 2020-02-01 by SAE International in United States

Companies across a wide range of segments are introducing Industry 4.0 (i4.0) technology at a rapid pace, turning the next-generation vision of manufacturing - the Factory of the Future - into reality. Many of the advances in this transformation have been in highly automated industries such as vehicle manufacturing. Conversely, the aerospace industry, with its staged approach to assembling aircraft, satellites and other products, has only begun to investigate how i4.0 technologies can improve operations, throughput, quality control and cost challenges.

Heterogeneous Integration Technology

Aerospace & Defense Technology: February 2020

  • Magazine Article
  • 20AERP02_08
Published 2020-02-01 by SAE International in United States

Integrating different types of devices and materials could increase their functional density, improving the performance of electro-optic systems for sensor applications.

By definition, “heterogeneous integration” (HI) refers to the integration of dissimilar components on a common platform. The term is extensively used in very diverse applications to encompass efforts to make previously separate functions operate together by an intimate fusion of components. It can mean a seamless integration of previously incompatible software, database, drugs or machine parts. The particular definition that applies here is the integration of dissimilar sensor components onto a common substrate to make new compact components that provide enhanced characteristics.

Evaluation of the Effects of Hydrogen Peroxide on Common Aircraft Electrical Materials

Aerospace & Defense Technology: February 2020

  • Magazine Article
  • 20AERP02_13
Published 2020-02-01 by SAE International in United States

Study aims to find a suitable decontaminant/disinfectant/sanitizer that can be used successfully in complex transportation vehicles with no negative impact on sensitive electronic equipment.

Among all of the large-scale disinfection and/or decontamination technologies available, vaporized hydrogen peroxide (VHP®) is of particular interest due to its rapid sterilization, easy usage, intrinsic environmental friendliness (i.e. simple by-products composed of only water and oxygen), and compatibility with many materials and systems.

Weyl Semimetals (WSM) for Electronics Applications

Aerospace & Defense Technology: February 2020

  • Magazine Article
  • 20AERP02_11
Published 2020-02-01 by SAE International in United States

New synthesized materials open the way to govern the density of helicity, axial charge, and its flow, axial current.

The major factor determining transport properties of solids is the number of electron states in a vicinity of Fermi level. In equilibrium, no macroscopic flow of electrons exists and, therefore, in order to create such flow, electrons must be excited over their equilibrium distribution. However, electrons with energies well below the Fermi level (compared to the characteristic energy scale kBT, where kB is the Boltzmann constant and T is the temperature), cannot acquire small excitation energy. Indeed, in this case, they would have energy corresponding to already occupied states, which is prohibited by the Pauli principle. In turn, well above the Fermi level, where excitation of electrons is not constrained by the Pauli principle, the electron states are not populated, thus making their contribution to the response negligible.

RAD-HARD Microelectronics for Space Applications

Aerospace & Defense Technology: February 2020

  • Magazine Article
  • 20AERP02_01
Published 2020-02-01 by SAE International in United States

For orbiting satellites, design requirements are extensive as a result of the extreme environment in space, including wide-ranging and rapidly changing temperatures, satellite body charging effects and high-energy particle bombardment and radiation. These dynamics drive the need for high-reliability engineering concepts for all system components. In the case of microelectronics, this takes a unique form and drives innovation for techniques to overcome these damaging effects.

Published 2020-02-01 by SAE International in United States

Today's intelligence, surveillance, and reconnaissance (ISR) platforms integrate state-of-the-art technologies and subsystems into airborne platforms intended to observe, detect, identify, and neutralize threats. Full motion video (FMV) sensors are essential assets and are routinely used on fixed-wing, rotary-wing, and manned and unmanned platforms to provide real-time situational awareness with minimal latency.
