Key Technology Challenges of Electric Ducted Fan Propulsion Systems for eVTOL

EPR202302711/22/2023

Electrical vertical takeoff and landing (eVTOL) vehicles for urban air mobility (UAM) are garnering increased attention from both the automotive and aerospace industries, with use cases ranging from individual transportation, public service, cargo delivery, and more. Distributed electric propulsion systems are their main technical feature; they determine vehicle size and propulsion efficiency and provide distributed thrust to achieve attitude control. Considering the intended role of eVTOL vehicles, ducted-fan systems are ideal choice for the propulsor, as the duct provides a physical barrier between the rotating blades and the human, especially during the take-off and landing phases. Key Technology Challenges of Electric Ducted Fan Propulsion Systems for eVTOL introduces the main bottlenecks and key enablers of ducted-fan propulsion systems for eVTOL applications. Based on the introduction and discussion of these important issues, this report will help eVTOL engineers understand the key technical issues and inspire them to develop the ideal solutions that will enable eVTOL vehicle deployment for UAM operations.

The Adoption of Digital Twins in Integrated Vehicle Health Management

EPR202302410/26/2023

To many, a digital twin offers “functionality,” or the ability to virtually rerun events that have happened on the real system and the ability to simulate future performance. However, this requires models based on the physics of the system to be built into the digital twin, links to data from sensors on the real live system, and sophisticated algorithms incorporating artificial intelligence (AI) and machine learning (ML). All of this can be used for integrated vehicle health management (IVHM) decisions, such as determining future failure, root cause analysis, and optimized energy performance. All of these can be used to make decisions to optimize the operation of an aircraft—these may even extend into safety-based decisions. The Adoption of Digital Twins in Integrated Vehicle Health Management, however, still has a range of unsettled topics that cover technological reliability, data security and ownership, user presentation and interfaces, as well as certification of the digital twin’s system mechanics (i.e., AI, ML) for use in safety-critical applications.

Unsettled Topics Concerning Automated Driving Systems and the Development Ecosystem SAAS Demo 10-17-23

EPR20200043/17/2020

With over 100 years of operation, the current automobile industry has settled into an equilibrium with the development of methodologies, regulations, and processes for improving safety. In addition, a nearly $2-trillion market operates in the automotive ecosystem with connections into fields ranging from insurance to advertising. Enabling this ecosystem is a well-honed, tiered supply chain and an established development environment. Autonomous vehicle (AV) technology is a leap forward for the existing automotive industry; now the automobile is expected to manage perception and decision-making tasks. The safety technologies associated with these tasks were presented in an earlier SAE EDGE™ Research Report, “Unsettled Technology Areas in Autonomous Vehicle Test and Validation.” In a later SAE EDGE™ Research Report, “Unsettled Topics Concerning Automated Driving Systems and the Transportation Ecosystem,” senior executives from the automotive ecosystem explored the impact of AV technology as they faced the prospect of this disruptive technology entering their marketplace. Interestingly, stable use-models and market penetration were all gated primarily by the demonstration of AV safety. Building on these previous verification and validation (V&V)-related reports, “Unsettled Topics Concerning Automated Driving Systems and the Development Ecosystem” explores the open issues in the shift of the development and supplier environment toward a new AV-enabled future. NOTE: SAE EDGE™ Research Reports are intended to identify and illuminate key issues in emerging, but still unsettled, technologies of interest to the mobility industry. The goal of SAE EDGE™ Research Reports is to stimulate discussion and work in the hope of promoting and speeding resolution of identified issues. SAE EDGE™ Research Reports are not intended to resolve the challenges they identify or close any topic to further scrutiny.

Unsettled Issues Concerning Semi-Automated Vehicles: Safety and Human Interactions on the Road to Full Autonomy

EPR20200012/28/2020

Across the span of the SAE International-defined Levels of Driving Automation, human drivers occupy a diverse range of responsibilities and authority on the vehicle movement and the monitoring of the outside environment. From both a technological and a regulatory perspective, there is a gap that divides lower levels of automation (L1 through L3) and higher levels of automation (L4 and L5). For those vehicles that require the cooperation between a human driver and the autonomous technology, it is important to ascertain the safety consequences of such a design choice. It is also important to understand what the transition between automated driving and manual driving entails for the human driver, as well as for the surrounding traffic. This SAE EDGE™ Research Report investigates unsettled issues concerning what is commonly referred to as “semi-automation,” including an overview of the role of human drivers, the quantification of the “transition-to-manual” problem, the role played by L3 toward full automation, and regulatory and moral considerations surrounding the deployment of these vehicles. NOTE: SAE EDGE™ Research Reports are intended to identify and illuminate key issues in emerging, but still unsettled, technologies of interest to the mobility industry. The goal of SAE EDGE™ Research Reports is to stimulate discussion and work in the hope of promoting and speeding resolution of identified issues. SAE EDGE™ Research Reports are not intended to resolve the issues they identify or close any topic to further scrutiny.

A book about nothing

Example/Book: A Semiotic Journey Through Simulated Realities

EXAMPLE/BOOK5/22/2025

In Example/Book, celebrated meta-narrative theorist Ellory Venn crafts a dazzling labyrinth of story and simulation. Ostensibly a guide to writing guides, this fictional "book within a book" explores what it means to create meaning in a world increasingly defined by artificial constructs. Blending speculative fiction, surreal philosophy, and academic satire, Example/Book follows a nameless compiler as they attempt to assemble the definitive manual on manuals, only to discover that the structure of their own reality is fractal, recursive, and entirely unreliable. A postmodern meditation on authorship, identity, and the limits of language, Example/Book challenges readers to consider: what happens when the example becomes the origin, and the book begins to write itself?

McLaren: The Engine Company

R-4853/13/2020

McLaren: The Engine Company is the previously untold story of McLaren Engines, an American company founded in 1969 by Bruce McLaren and his partners to build engines for McLaren's legendary Can-Am and Indy Cars. From this base in suburban Detroit were born the mighty big-block Chevrolet V8s that powered the iconic orange cars to two of their five consecutive Cam-Am championships. McLaren's busy dyno rooms also spawned the howling turbo Offenhausers that put Mark Donohue and Johnny Rutherford in Victory Lane at Indianapolis three times between 1972 and 1976. For decades this non-descript shop was the hotbed of horsepower for factories and top independents alike. McLaren Engines developed the turbocharged Cosworth DFV Formula 1 engine that powered Indy cars for both Team McLaren and Penske Racing. It rendered BMW's turbo engine for U.S. IMSA racing that later became BMW's Formula 1 weapon. The long list of race engines developed here powered Buick Indy and IMSA cars, BMW GTP cars, Cadillac LeMans prototypes, Porsche Trans-Am 944s and David Hobbs' F5000 single seaters. There were McLaren-built big-block turbo V8s for offshore boat racing and even a Cosworth-Vega engine for American dirt tracks! Author Roger Meiners combines his life-long passion for motor racing and technology with his historian's sensibilities to make the engines, cars, and key personalities come alive within this book's pages. Ride along with Meiners as he uncovers little-known details of the company's transition from a race shop to an engineering company, developing lust-worthy performance cars such as the sensational 1987 Buick GNX, the 1989 Pontiac Grand Prix Turbo, the FR500 Ford Mustang concept, and other projects that the public never saw. Today the company, known as McLaren Engineering, is a subsidiary of Canada-based Linamar Corporation, and is sought after by global automakers for its unrivaled testing, development and manufacturing capability.
