EGR coolers are used in combustion engines to reduce NOx emissions. However, heat transfer in these coolers also results in thermophoresis-temperature-gradient driven motion of suspended particles towards cooler regions-which leads to significant soot deposition. Presenter Meisam Mehravaran

This presentation shows the SCADE System product line for systems modeling and generation based on the SysML standard and the Eclipse Papyrus open source technology. SCADE System has been developed in the framework of Listerel, a joint laboratory of Esterel Technologies, provider of the SCADE�, and CEA LIST, project leader of the Eclipse component, Papyrus. From an architecture point of view, the Esterel SCADE tools are built on top of the SCADE platform which includes both SCADE Suite�, a model-based development environment dedicated to critical software, and SCADE System enabling model-based system engineering. SCADE System includes Papyrus, an open source component (under EPL license), integrated in the modeling platform of Eclipse. Using this integrated modeling platform, both system and software teams share the same environment for system development. Furthermore, other model-based tools can be added to the environment, due to the use of Eclipse.

With the increased usage of Carbon Fiber Reinforced Plastics (CFRP) in the aircraft industry, there has been increased pressure to improve cutting tool life. Tungsten carbide tools were the first to be applied to CFRP materials. Poly Crystalline Diamond (PCD) tools also became an acceptable material to be used as a cutting tool material. In recent years, Chemical Vapor Deposition (CVD) diamond tools have become more popular as a cutting tool material for CFRP. This study compares these possible cutting tool materials in the drilling of CFRP. Wear is measured as well as hole quality. Life is determined by common industry standards with regard to fiber break out in a common CFRP material. An economic analysis is conducted in order to determine cost per hole.

AS8049A currently requires adjustable features on aircraft seats to be designed so they can be returned to the positions required for taxi, takeoff and landing by the occupant without the release of the occupant restraints. This ARD will demonstrate Aviation Industry support for revisions to TSO-C39c and TSO-C127a to allow Technical Standard Order (TSO) approval of aircraft seat products designed with adjustable features that require the release of occupant restraints to return the feature to the taxi, takeoff and landing position.

This SAE Standard applies to equipment to be used to recovery R-152a refrigerant only. Refrigerant recovery equipment is required to ensure adequate refrigerant recovery to reduce emissions and provide safe and accurate service of the AC system. Equipment shall be certified to meet all performance requirements outlined in this document.

This SAE standard applies to refrigerant identification equipment to be used for identifying an acceptable level of R-152a purity in a refrigerant tank or vehicle MAC system labeled as containing R-152a, and not misidentify other refrigerants.

This SAE Standard applies to equipment to be used with R-152a refrigerant only. It establishes requirements for equipment used to recharge R-152a to an industry accepted accuracy level and purity levels defined in SAE J2099. Refrigerant service equipment is required to ensure adequate refrigerant recovery to reduce emissions and provide for accurate recharging of mobile air conditioning systems. Equipment shall be certified to meet all performance requirements outlined in this document and international/regional construction and safety requirements as outlined in this document.

This SAE Standard provides testing and functional requirements to meet specified minimum performance criteria for electronic probe-type leak detectors suitable for use with R-152a, an A2 flammable refrigerant. The equipment specified here will identify smaller refrigerant leaks when servicing motor vehicle air conditioning systems, including those engineered with improved sealing and smaller refrigerant charges to address environmental concerns and increase system efficiency.

This SAE Aerospace Recommended Practice (ARP) provides guidance to develop and assure validation and verification of IVHM systems used in autonomous aircraft, vehicles and driver assistance functions. IVHM covers a vehicle, monitoring and data processing functions inherent within its sub-systems, and the tools and processes used to manage and restore the vehicle’s health. The scope of this document is to address challenges and identify recommendations for the application of integrated vehicle health management (IVHM) specifically to intelligent systems performing tasks autonomously within the mobility sector. This document will focus on the core aspects of IVHM for autonomous vehicles that are common to both aerospace and automotive applications. It is anticipated that additional documents will be developed separately to cover aspects of this functionality that are unique to each application domain.

This SAE Aerospace Information Report will be a compilation of system safety engineering and management terms and definitions covering concepts used across multiple products and disciplines

This recommended practice provides users with raw GNSS measurements to facilitate positioning, navigation, or timing solutions.

This standard provides recommended practices to significantly enhance the ability of PNT users to defend against a range of interference, jamming, and spoofing phenomena.

Provide a high level standard that resolves the gaps of SAE J1739 and other FMEA standards to support companies that currently use the cancelled MIL-Std-1629a FMECA Standard. The new standard will define: 1) the relationship and connection between FMEA/FMECA and maintainability and Supportability. 2) define the purpose of qualitative and quantitative criticality analysis and recommendations on usage of each within FMEA/FMECA. 3) how and when to incorporate Model-Based systems engineering to support FMEA/FMECA

This standard establishes the inertial and health monitoring data interface requirements for inertial measurement units used for military and aerospace vehicle applications.

This standard establishes the SAE2020 compliant inertial data interface requirements for simulator integration with inertial navigation systems used for military and aerospace vehicle applications.
