2019-08-26
CURRENT
ARINC680
This document describes the technical requirements, architectural options, and recommended interface standards to support an Autonomous Distress Tracking (ADT) System intended to meet global regulatory requirements for locating aircraft in distress situations and after an accident. This document is prepared in response to International Civil Aviation Organization (ICAO) and individual Civil Aviation Authorities (CAAs) initiatives.

Comparing Dolly Rollover Testing to Steer-Induced Rollover Events for an Enhanced Understanding of Off-Road Rollover Dynamics

2011-11-01
The field of motor vehicle rollover research and testing has been one of multiple and varied approaches, dating back to at least the 1930's. The approach has been as simple as tipping a vehicle over at the top of a steep hill ( Wilson et al., 1972 ), to as complex as releasing a vehicle from an elevated roll spit mounted to the rear of a moving tractor and trailer ( Cooper et al., 2001 and Carter et al., 2002 ).

Using Programming and Simulation to Develop Optimized Processes for Automated Fiber Placement (AFP) CNC Machines

2012-03-21
Many manufacturing companies want to apply AFP technology to complex high-curvature part shapes. As new AFP machine technologies are developed to specifically apply material over complex shapes, new and innovative NC programming approaches are needed to successfully, reliably, and accurately apply material with good consolidation, while meeting the fiber direction and coverage requirements. A big issue with AFP is the production rate vs. part complexity. Most complex shapes can be created with a single .125? wide strip (tow) of material. But the production time would be impractically long. So machine builders create 6, 8, 16, even 32 tow AFP heads, and use the widest tow possible for the highest laydown rates. But then wide compaction rollers on these systems have difficulty consolidating material over curved surfaces, and the minimum steering radius of wider tows challenge the software?s ability to meet the layup requirements.

Spotlight on Design: 3D Printing in the Automotive Industry

2015-12-22
“Spotlight on Design” features video interviews and case studies, focusing on technology breakthroughs, hands-on testimonials, and the importance of fundamentals. Viewers are virtually taken to industry labs and research centers to learn how design engineers solve real-life problems. These challenges include enhancing product performance, reducing costs, improving quality and safety, while decreasing environmental impact, and achieving regulatory compliance. In the episode “Additive Manufacturing: 3D Printing in the Automotive Industry” (20:00), engineers from Fiat Chrysler Corporation (FCA) explain the importance of using 3D printing to test multiple design scenarios and develop solutions that can be quickly evaluated on test tracks. And Local Motors shows how it builds a vehicle from the ground up with a 3D printer, and without a traditional assembly line.
