A Season on the Mat
Unbeaten through his years of high school wrestling in Waterloo, Iowa, and almost all the way through Iowa State University, Dan Gable went on to coach at the University of Iowa for twenty-one years, winning the Big 10 every year and the NCAA championship fifteen times.
Electric Charging Intended Functionality, Availability, and Equity Inclusion
As unprecedented growth in EV sales is expected, and the number of public charging stations must be planned accordingly as charger up-time and functionality (i.e., availability) is the number one factor for users once the charging system is installed. Electric Vehicle Intended Functionality, Availability, and Equity Inclusion informs current customers and potential purchasers of functionality, availability, and equity inclusion issues with EV charging systems currently in production and in use across North America and Europe. Note that if shortages of available chargers are recognized and exposed across the US, this could then have a negative impact on future potential EV customers from making the “leap” from traditional ICE vehicles to EVs.

Emerging Automotive Battery Chemistries
There is an urgent need to decarbonize various industry sectors, including transportation; however, this is difficult to achieve when relying solely on today’s lithium-ion (Li-ion) battery technology. A lack of sufficient supply of critical materials—including lithium, nickel, and cobalt—is a major driving force behind research, development, and commercialization of new battery chemistries that can support this energy transition. Many emerging chemistries do not face the same supply, safety, and often durability challenges associated with Li-ion technology, yet these solutions are still very immature and require significant development effort to be commercialized. Emerging Automotive B...
Deployment of Parallel Kinematic Machines in Manufacturing
The field of parallel kinematics was viewed as being potentially transformational in manufacturing, having multiple potential advantages over conventional serial machine tools and robots. However, the technology never quite achieved market penetration or broad success envisaged. Yet, many of the inherent advantages still exist in terms of stiffness, force capability, and flexibility when compared to more conventional machine structures. Deployment of Parallel Kinematic Machines in Manufacturing examines why parallel kinematic machines have not lived up to original excitement and market interest and what needs to be done to rekindle that interest. A number of key questions and issues need to be explored to advance the technology further. Click here to access the full SAE EDGETM Research Report portfolio. https://doi.org/10.4271/EPR2022010
Unsettled Topics on the Feasibility and Desirability of Using Additive Manufacturing in the Mobility Industry
Depending on the industry and application, views on additive manufacturing (AM), or “3D printing,” range from something that will transform an industry to it being another overhyped technology that will only find niche applications. Most views fall somewhere in between, with the most common one being that it depends on the application and technology. Because of the ability to directly produce parts from a digital file, views often include dependence on when and where the part is needed. This introduces the crux of the matter, which is how to determine when the use of AM is feasible and desirable, which is made all the more complicated by the fact that not only is AM technology in general...
Pitfalls of Designing, Developing, and Maintaining Modular Avionics Systems in the Name of Sustainability
Sustainability is both an ethical responsibility and business concern for the aerospace industry. Military and commercial avionics developers have pushed toward a common standard for interfaces, computing platforms, and software in hopes of having “reusability” and reducing weight with backplane computing architectures which, in theory, would support commonality across aircraft systems. The integrated modular avionics (IMA) and military Future Airborne Capability Environment (FACE) standards are two such examples. They emerged to support common computing architectures for reuse and sustainability concepts, from the beginning of aircraft development to the sundown or mortality phase. Pitf...
Micromobility and the Next Infrastructure Wave
US transportation infrastructure is dominated by the automobile form factor. Alternative modalities of movement, such as bikes, golf carts, and other micromobility options, have existed but are decidedly at a lower tier of importance. Even pedestrian access ways are not overly emphasized in the US transportation system. This lack of prioritization matches the reality that the vast majority of people and commerce moves through the motor vehicle infrastructure, with micromobility sitting in the periphery. Additionally, given the current lack of commercial applications, there are limited direct fee-based funding mechanisms connected to micromobility form factors. Micromobility and the Next Infr...
Unsettled Domains Concerning Electric Propulsion Technology for Commercial Aircraft
According to some, electric propulsion is already on its way down the “trough of disillusionment.” This report argues that while there are some concerns with associated technologies, such pessimism is unwarranted. Yes, battery systems can be more energy dense; charging standards are late in being developed; it is not clear what technologies and architectures will win out for which sectors; we still have to figure out how to deal with thermal management issues at all levels in future designs; and what might be the certification standards for electric aircraft. But that does not mean that these issues will not be addressed. Yes, these unsettled questions may take a little longer to solve t...
Unsettled Topics Concerning Autonomous Public Transportation Systems
With billions of dollars of investment and events like DARPA’s Grand Challenges automated driving technology has been making its way toward commercialization. While the enabling technology for SAE Level 4 and 5 automated vehicles (AV) has not yet matured, specific restricted-use models such as “robo-taxis” and automated truck convoying show great promise. Now, cities are across the world are looking to AVs to solve their public transportation issues. With low speeds and fixed route, public transportation is an ideal application for AVs. From a business angle, AVs could leverage existing public transport models and infrastructure while providing superior quality of service for disadvant...
Unsettled Issues Regarding the Use of eVTOL Aircraft during Natural Disasters
Recent advancements of electric vertical takeoff and landing (eVTOL) aircraft have generated significant interest within and beyond the traditional aviation industry, and many new and novel applications have been identified and are under development. One promising application is rapid response during natural disasters, which can complement current capabilities to help save lives and enhance post-disaster recoveries. The Use of eVTOL Aircraft During Natural Disasters presents issues that need to be addressed before eVTOL aircraft are integrated into natural disaster response operations: eVTOL vehicle development Detect-and-avoid capabilities in complex and challenging operating environments Autonomous and remote operations Charging system compatibility and availability Operator and controller training Dynamic air space management Vehicle/fleet logistics and support Acceptance from stakeholders and the public Click here to access the full SAE EDGETM Research Report portfolio. https://doi.org/10.4271/EPR2022001
