RAMBHA-LP (Radio Anatomy of Moon Bound Hypersensitive Ionosphere and Atmosphere - Langmuir Probe) is one of the key scientific payloads onboard the Indian Space Research Organization’s (ISRO) Chandrayaan-3 mission. Its objectives were to estimate the plasma density and its variations on the near lunar surface. The probe was initially kept in a stowed condition attached to the lander. A mechanism was designed and realized to meet the functional requirement of deploying the probe at a distance of 1 meter, equivalent to the Debye length of the probe in the moon’s plasma environment. The probe deployment mechanism consists of the Titanium alloy spherical probe with a Titanium Nitride coating on its surface to achieve a constant work function, a long carbon-fiber-reinforced polymer boom, a double torsion spring, a dust-protection box, and a shape-memory alloy-based Frangibolt actuator for low-shock separation. The entire mechanism weighed less than 1.5 kilograms.
Compared with urban areas, the road surface in mountainous areas generally has a larger slope, larger curvature and narrower width, and the vehicle may roll over and other dangers on such a road. In the case of limited driver information, if the two cars on the mountain road approach fast, it is very likely to occur road blockage or even collision. Multi-vehicle cooperative control technology can integrate the driving data of nearby vehicles, expand the perception range of vehicles, assist driving through multi-objective optimization algorithm, and improve the driving safety and traffic system reliability. Most existing studies on cooperative optimization control of multiple vehicles is mainly focused on urban areas with stable environment, while ignoring complex conditions in mountainous areas and the influence of driver status. In this study, a digital twin based multi-vehicle cooperative warning system was proposed to improve the safety of multiple vehicles on mountain roads.
Due to the high center of gravity of light-duty vehicles, rollover accidents can easily occur during high-speed cornering and lane changes. In order to prevent the deformation of the body structure, which would restrict the survival space and cause compression injuries to occupants, it is necessary to investigate methods for mitigating these incidents. This paper establishes a numerical model of right-side rollover for a commercial light-duty vehicle and occupant living space in accordance with ECE R66 regulations. By applying an initial rotation speed and gravitational acceleration field to the vehicle, the body was turned to the right side, and the accuracy of the model is verified by experiment. According to the results, the material and size parameters of the key components of the right side pillar are selected as design variables.
When the aircraft towing operation is carried out in the narrow areas such as the hangar or parking apron, it has a high safety risk for aircraft that the wingtips may collide with the surrounding aircraft or the airport facility. A real-time trajectory prediction method for the towbarless aircraft taxiing system (TLATS) is proposed to evaluate the collision risk based on image recognition. An improved Long Short-Term Memory (LSTM) encoder-decoder model is established to recognize the targets and extracts the corresponding features by using the recurrent neural networks. The spatial configuration information of the aircraft's wings as well as the fixed facility or moving obstacles in the narrow area are obtained to predict the future motion trends. Further, a video dataset featuring various aircraft in real towing scenarios is constructed for training and testing purposes.

Purpose: This award celebrates the successes of women in the engineering profession and recognizes their leadership and technical contributions in the aerospace, automotive and commercial vehicle sectors. It serves to broaden the awareness of the reach and impact of women working in mobility engineering, and opening doors for young girls interested in science, technology, engineering, and mathematics (STEM) who wish to pursue engineering careers. Rodica Baranescu, Ph.D. made a generous gift in 2011 to establish this award. Dr. Baranescu is Past President of SAE International, an SAE Fellow and a member of the National Academy of Engineering. As a mechanical engineer, she began her professional and academic career in her native country, Romania, before immigrating to the United States in 1980 and was later the first woman elected President of SAE International in 2000.
This AIR provides a detailed example of the aircraft and systems development for a function of a hypothetical S18 aircraft. In order to present a clear picture, an aircraft function was broken down into a single system. A function was chosen which had sufficient complexity to allow use of all the methodologies, yet was simple enough to present a clear picture of the flow through the process. This function/system was analyzed using the methods and tools described in ARP4754A/ED-79A. The aircraft level function is “Decelerate Aircraft On Ground” and the system is the braking system. The interaction of the braking system functions with the aircraft are identified with the relative importance based on implied aircraft interactions and system availabilities at the aircraft level. This example does not include validation and verification of the aircraft level hazards and interactions with the braking system.
Purpose: This award recognizes those who make a valuable contribution of time and leadership in support of the SAE standards and technical committees through research, test methods and procedures, development of standards and/or external representation of the Society for similar works. The SAE International ESC Outstanding Achievement Award was established to honor the 1945 SAE International President James M. Crawford. Criteria: Extraordinary leadership in the activities of a committee. Outstanding contributions in the form of research, test methods and procedures. Advancing SAE image as the premier international standards developer. Exceptional effort related to document production. Outstanding commitment to technical committee(s). Eligibility: The top awardee will receive the SAE International Cooperative Engineering Medal honoring Arch T. Colwell. Members of the Selection Committee are not eligible for the award while serving on the committee.
Purpose: This award honors the best innovation and/or implementation of new ideas in boosting systems by an individual or a team that has positively impacted the industry. This award was established in 2019 through the generous support of IHI Corporation. Criteria: New ideas not just in the area of performance, but also in the areas of fuel economy, emissions, cost, quality, and reliability that generate a positive impact within the automotive industry will be considered. Eligibility: Members of the Selection Committee are not eligible for this award while serving on the committee. Two years must pass before former members of the Selection Committee are eligible to receive the award. Recognition: This includes an honorarium and an award that is presented at an SAE Event.
Purpose: This award provides funding to a Formula SAE® (FSAE) team to assist with the development of their vehicle design. Established in 2004, this award honors William R. "Bill" Adam's contribution to FSAE and his lifelong dedication to mentoring young engineers. Bill was a longtime SAE member and was an accomplished automotive industry engineer who helped develop the integrated Manifold-Muffler-Catalyst design.

Purpose: To recognize students who demonstrate outstanding technical expertise through the presentation of a technical paper or engineering project in association with a major SAE meeting, event or student competition. The late Dr. Phil Myers and his wife Jean were lifelong devotees to students and SAE International. Myers was a renowned expert on internal combustion engines, and before his retirement, a professor at the University of Wisconsin-Madison. Together with his wife, they set a high standard for excellence, concern for students, and involvement with SAE. In their honor, an award was established in 1997, to annually recognize the best technical writing by a student. Criteria: The writings must be based on work done by the author(s) while an undergraduate or graduate student and presented at a major SAE event.
