Editorial Autonomy's data binge is more like a 5-course meal. Big Data, Big Challenges Cloud services and multiple partnerships are issues the mobility industry grapples with as data implications expand outside the vehicle. Reinventing the Automobile's Design The convergence of electric propulsion, Level 5 autonomy, and the advent of car-free urban zones, is driving new approaches to vehicle design and engineering. When Steering Isn't Steering Anymore High-level autonomy requires new thinking for even basic vehicle controls. Steer-by-wire technology eases some of the complexities automated driving presents-and offers desirable new possibilities. Autonomy and Electrification: A Perfect Match? Combining SAE Level 4/5 functionality and EV platforms brings chal-lenges-and opportunities for cost reduction and systems optimization. Who's Ahead in the Automated-Driving Race? The 2018 Navigant Research Leaderboard study brings interesting insights on the industry's progress.
Inside the cell walls The high cost of lithium-ion batteries is a prison that has largely kept electric vehicles off the street; the keys to their release are more effective—but not more expensive—cell chemistries.

HPD: HPM II Design Tool SAE Part#EA-3HPD The H-Point design tool is a set of data used during design in conjunction with the H-Point machine. In an IGES file format the HPM II is positioned in 1 neutral position and the 4 pre-defined postures. The file is uploaded into the resident CAD system and the user must add constraints and parametrics. The HPD is referenced in J 826_2002 as a critical component to the design applications of the HPM II.
Voted one of the top ten new design books, this lavishly illustrated book is a colorful account of Le Corbusier's love affair with the automobile, his vision of the ideal vehicle, and his tireless promotion of a design that industry never embraced. Le Corbusier, who famously called a house "a machine for living," was fascinated-even obsessed-by another kind of machine, the automobile. His writings were strewn with references to autos: "If houses were built industrially, mass-produced like chassis, an aesthetic would be formed with surprising precision," he wrote in Toward an Architecture (1923). In his "white phase" of the twenties and thirties, he insisted that his buildings be photographed with a modern automobile in the foreground. Le Corbusier moved beyond the theoretical in 1936, entering (with his cousin Pierre Jeanneret) an automobile design competition, submitting plans for "a minimalist vehicle for maximum functionality," the Voiture Minimum.

This method describes a gravimetric procedure for the determination of solid particle contamination in packaged aircraft turbine lubricants and related fluids. This method is Federal Test Method 791, Method 3010 used in Aerospace Standard 5780.
This specification will establish the critical controls and requirements for the production of reliable, repeatable, reproducible aerospace parts by Laser Sintering fabrication but is not limited to such application. This procedure will establish guidelines that users shall follow to approve new machines, processes, and materials. Specifically, this specification covers the configuration of the machine, operating software, machine calibration, machine and build parameters, and testing methodology required to create high performance aerospace parts. This specification also outlines the user’s responsibility for following the established guidelines and documentation requirements
This specification will establish the minimum requirements for Laser Sintering feedstock to be used in conjunction with the Laser Sintering process specification for fabricating LS parts. The Laser Sintering part (with/without subsequent processing) may be used for, but not limited to, aerospace applications. This specification outlines the minimum technical and documentation requirements for Laser Sintering materials.
The scope of this document is to clearly lay out the path for an organization to implement a CBM approach to maintenance. The practices will include both CBM in design and in the support phase for fielded equipment.
This document will address techniques or methods that have been used within the industry to address the problem of engine stability margin accounting when combinations of distortion types exist in an aircraft installation. Its focus is combining temperature, planar wave, and swirl distortion with time-variant spatial total pressure distortion. Example methodologies will be presented along with example cases where co-existing distortions have been evaluated. It will also address the areas where the industries' knowledge base is lacking (experimental data or computational methods) and the future work that is needed for methodology development in these areas. This document is viewed to be updated every five years as more information (data either experimentally or analytically) becomes available.

This method is used for determining the compatibility of a candidate lubricant with specific reference lubricants. The reference lubricants will typically be mandated by the product specification against which the candidate lubricant is being compared. This method is based on Federal Standard 791 method 3403 and Defence Standard 05-50 (Part 61) method 24, incorporating the modifications called for in SAE AS5780.
THE HIGH-TEMPERATURE DEPOSITION TEST (HTDT) METHOD IS DESIGNED TO EVALUATE THE DEPOSITION AND DEGRADATION CHARACTERISTICS OF TURBINE LUBRICANTS WHEN STRESSED UNDER MIXED-PHASE FLOW CONDITIONS FOUND IN CERTAIN PARTS OF AVIATION GAS TURBINE ENGINES.

"Spotlight on Design: Insight" features an in-depth look at the latest technology breakthroughs impacting mobility. Viewers are virtually taken to labs and research centers to learn how design engineers are enhancing product performance/reliability, reducing cost, improving quality, safety or environmental impact, and achieving regulatory compliance. As global concerns about the negative consequences of greenhouse gases on the environment increase, regulatory agencies around the world are taking serious steps to address the issue of tailpipe emissions In the episode "Fuel Efficiency: Fuel Economy Testing" (12:01), engineers at the EPA’s National Vehicle and Fuel Emissions Laboratory demonstrate how different vehicles are tested for emissions, and AVL’s technical team shows how accurate tailpipe emissions can be measured and reported.

Shape memory materials undergo temperature-induced martensitic phase transformations that involve reversible dimensional changes. In performing these changes in shape, the shape-memory material is able to do work against external constraints, and this is the basis for shape-memory low-temperature heat engines. The transformation temperatures on heating and cooling are often not very different (little hysteresis) and are well defined and reproducible. Furthermore, these temperatures can be adjusted by varying the composition of the shape memory alloy. Internal combustion engines dissipate approximately two-thirds of the fuel energy as heat to the exhaust and coolant systems. A low-temperature heat engine could convert a fraction of this heat energy to useful work. This paper discusses the conceptual basis for the application of shape memory heat engines to internal combustion engine powered vehicles. Metallurgical and thermodynamic factors are discussed, as well as engine efficiency.
