Aluminum-lithium alloys are extensively used across various industries due to their exceptional strength-to-weight ratio, excellent fatigue/corrosion resistance and good thermal stability. These attributes, combined with improved weldability and ease of fabrication, make them ideal for lightweight engineering applications in sectors such as aerospace, automotive, and defense. Additive manufacturing (AM) offers unique opportunities to fully leverage the potential of aluminum-lithium alloys by enabling the fabrication of complex geometries, minimizing material waste, and supporting on-demand production. This paper explores the significance of lightweight materials, traces the evolution of aluminum-lithium alloys and provides a comprehensive overview of their AM. It discusses the properties and real-world applications of these alloys and examines various AM techniques employed in their processing. Key advancements in the AM of aluminum-lithium alloys are reviewed, including novel alloy

Accurate defect quantification is crucial for ensuring the serviceability of aircraft engine parts. Traditional inspection methods, such as profile projectors and replicating compounds, suffer from inconsistencies, operator dependency, and ergonomic challenges. To address these limitations, the 4D InSpec® handheld 3D scanner was introduced as an advanced solution for defect measurement and analysis. This article evaluates the effectiveness of the 4D InSpec scanner through multiple statistical methods, including Gage Repeatability and Reproducibility (Gage R&R), Isoplot®, Youden plots, and Bland–Altman plots. A new concept of Probability of accurate Measurement (PoaM)© was introduced to capture the accuracy of the defect quantification based on their size. The results demonstrate a significant reduction in measurement variability, with Gage R&R improving from 39.9% (profile projector) to 8.5% (3D scanner), thus meeting the AS13100 Aerospace Quality Standard. Additionally, the 4D InSpec

This information report identifies and evaluates isolation building blocks applicable to TA sandboxing within a HPSE. These building blocks can be used to support SAE J3101 TA requirements for sandboxing of TAs and secure communication between TAs. TAs must execute within their own trust domain to prevent compromise of the HPSE and other TAs. TA trust domain isolation strength may vary depending on the risk profile of the TA deployed, hence the requirement for isolation building blocks to match the risk profile. A multitenancy TA HPSE has a higher risk profile than multiple TAs from the same source (e.g., OEM). TA multitenancy must not compromise the security properties of the HPSE (the secure integration and execution of trusted multi-vendor code). In this report, we provide information on the following: HPSE TA use cases and risk profiles HPSE TA isolation building blocks for manufacturers Threat analysis to determine the effectiveness of isolation security models As the ECU E/E

Achieving compression ignition (CI) with ethanol, a renewable fuel, comes with challenges because of its much lower cetane number compared to diesel. Additionally, ethanol’s high cooling potential and high volatility compared to diesel also offer challenges and opportunities to achieving robust, high-efficiency CI. Increasing the compression ratio (CR) and expanding the injection strategy beyond a conventional close-coupled pilot-main diesel injection strategy can help overcome these challenges. This work experimentally tested ethanol CI with several different injection strategies with CRs ranging from 16.3 to 22.3. The results showed that in homogeneous charge CI (HCCI), increasing the CR improved thermal efficiency but incurred a combustion efficiency penalty. In any CI concept, increasing the CR lowered the required intake temperature to achieve ignition. Using close-coupled pilot injections is an effective way to achieve ethanol CI, but it was also shown that HCCI-like intake

Automotive wooden interiors are increasingly popular among consumers for their excellent appearance and texture. However, low light transmittance limits their application in automotive interior smart surfaces. This study explores light transmission technology for wood veneer in automotive interiors, proposing two solutions based on the properties of wood veneer: the light-transmitting veneer solution and the laser-engraved beacon solution. Both solutions were tested through production experiments to evaluate the light transmission effects and process feasibility. Experimental results show that the light-transmitting veneer solution significantly improves the light transmittance of wood veneers through material modification, but instability in structure and materials leads to the difficulty of presenting a better light transmission effect. In contrast, the laser-engraved beacon solution achieves clear and stable light transmission effects by directly processing light-transmitting
