Item level serialization traceability, defined as the ability to track and trace products, items or components through the supply chain from product manufacturing all the way to the end of life service, has significant value in the aerospace industry. Many items become susceptible to counterfeiting when their origin and authenticity cannot be verified and Item level serialization and traceability fosters supply chain integrity. Data Matrix and radio-frequency identification (RFID) are two common methods that enable detailed information about the manufacturer. However, these methods are not generally compatible with fasteners due to the small size of the fasteners and the cost of these methods. Fasteners are the most commonly used parts on an aircraft and rely on lot level traceability associated with packaging to provide a level of supply chain risk management. However, the association of individual fasteners to parental lots is often lost once the fasteners are removed from packaging. We demonstrate a completely new approach to develop item level serialization traceability for aerospace fasteners. It is demonstrated that this label-free traceability can be realized…

Effect of alternative fuels on marine engine performance

Aalto University-Michal Wojcieszyk, Yuri Kroyan, Martti Larmi, Ossi Kaario, Kai Zenger
  • Technical Paper
  • 2019-01-2230
Published 2019-12-19 by SAE International in United States
Marine transportation sector is highly dependent on fossil-based energy carriers. Decarbonization of shipping can be accomplished by implementing biobunkers into an existing maritime fuel supply chain. However, there are many compatibility issues when blending new biocomponents with their fossil-based counterparts. Thus, it is of high importance to predict the effect of fuel properties on marine engine performance, especially for new fuel blends. In the given work, possible future solutions concentrated on liquid fuels are taken into account. Under consideration are such fuels as biodiesel (FAME), hydrotreated vegetable oil (HVO), straight vegetable oil (SVO), pyrolysis oil, biocrude, and methanol. Knowledge about the behavior of new fuel in an existing engine is notably important for decision makers and fuel producers. Hence, the main goal of the present work is to create a model, which can predict the engine performance from the end-user perspective. For the purpose of modeling, only the latest research on marine fuels is taken into account. In the current approach, results from a representative measurement set-up are compared in order to create a uniform…

Marking Aircraft Components

  • Magazine Article
  • TBMG-35683
Published 2019-12-01 by Tech Briefs Media Group in United States

Numbers are critical to the smooth functioning of the international aerospace industry. Regulatory authorities such as the Federal Aviation Authority (FAA) and the US Department of Defense (DoD) mandate that aero components be permanently marked to ensure authenticity and traceability throughout the supply chain and into service.

Published 2019-11-01 by SAE International in United States

The automotive industry has reached a strategic inflection point, where significant structural change is driving greater levels of instability on one hand, and opportunity (for some) on the other. That's the conclusion I'm hearing in discussions with suppliers and OEMs.

The Challenge of Replacing Hard Chrome

  • Magazine Article
  • TBMG-35359
Published 2019-10-01 by Tech Briefs Media Group in United States

The search for a suitable replacement for hard chrome on aerospace components has been a key supply chain priority for aircraft manufacturers. This is because of the documented health risks to workers and the impact on the environment from exposure to hexavalent chromium, a carcinogen that occurs during the chrome plating process and is the most toxic form of chromium.

The Future of 3D Printing: From Prototyping to Production

  • TBMG-35372
Published 2019-10-01 by Tech Briefs Media Group in United States

In today’s world of medical device manufacturing, cost pressures are very real. At the same time, cost savings can be just as real, especially when companies examine their manufacturing processes for greater efficiencies. One area that is gaining particular attention is metal stamping of previously machined, metal injection-molded, or laser-cut parts.
