Textile and Flexible Plastics Committee
This document reviews the state of the art for data scaling issues associated with air induction system development for turbine-engine-powered aircraft. In particular, the document addresses issues with obtaining high quality aerodynamic data when testing inlets. These data are used in performance and inlet-engine compatibility analyses. Examples of such data are: inlet recovery, inlet turbulence, and steady-state and dynamic total-pressure inlet distortion indices. Achieving full-scale inlet/engine compatibility requires a deep understanding of three areas: 1) geometric scaling fidelity (referred to here as just “scaling”), 2) impact of Reynolds number, and 3) ground and flight-test techniques (including relevant environment simulation, data acquisition, and data reduction practices). The Model-to-Full Scale Subcommittee of the S-16 Turbine Engine Inlet Flow Distortion Committee has examined archives and has obtained recollections of experts regarding air induction system development

Truck and Bus Wheel Committee
This SAE Standard describes a laboratory test procedure for measuring the vibration damping performance of a system consisting of a damping material bonded to a vibrating cantilevered steel bar. The bar is often called the Oberst bar (named after Dr. H. Oberst) and the test method is often called the Oberst bar test method. Materials for damping treatments may include homogeneous materials, nonhomogeneous materials, or a combination of homogeneous, nonhomogeneous, and/or inelastic (such as aluminum foil) materials. These materials are commonly installed in transportation systems such as ground vehicles, marine products, and aircraft to reduce vibration at resonance, and thus reduce the noise radiation from the vibrating surface. The test method described herein was developed to rank order materials for application on panels using general automotive steel but also may be applicable to other situations or conditions. Damping performance for most materials and systems varies as a function
Acoustical Materials Committee
This SAE Standard provides the specifications and procedures for using the H-point machine (HPM1) to audit vehicle seating positions. The HPM is a physical tool used to establish key reference points and measurements in a vehicle (see Figure 1 and Appendix A). The H-point design tool (HPD) is a simplified CAD2 version of the HPM, which can be used in conjunction with the HPM to take the optional measurements specified in this document, or used independently during product design (see Appendix D). These H-point devices provide a method for reliable layout and measurement of occupant seating compartments and/or seats. This document specifies the procedures for installing the H-point machine (HPM) and using the HPM to audit (verify) key reference points and measurements in a vehicle. The devices are intended for application at designated seating positions. They are not to be construed as tools that measure or indicate occupant capabilities or comfort. They are not intended for use in

Three levels of fan structural analysis are included in this practice: a Initial structural integrity. b In-vehicle testing. c Durability (laboratory) test methods. The initial structural integrity section describes analytical and test methods used to predict potential resonance and, therefore, possible fatigue accumulation. The in-vehicle (or machine) section enumerates the general procedure used to conduct a fan strain gage test. Various considerations that may affect the outcome of strain gage data have been described for the user of this procedure to adapt/discard depending on the particular application. The durability test methods section describes the detailed test procedures for a laboratory environment that may be used depending on type of fan, equipment availability, and end objective. The second and third levels build upon information derived from the previous level. Engineering judgment is required as to the applicability of each level to a different vehicle environment or a
Cooling Systems Standards Committee
The scope of this document is to provide an overview of the risks and protective precautions to ensure safe and effective testing procedures for the test personnel and the vehicle during the testing of a hydrogen fuel cell vehicle. The main risks associated with a hydrogen fuel cell vehicle are the fuel cell stack, hydrogen storage vessel, fuel cell system components and the high voltage battery. Risks could be summarized from the battery into thermal runaway possibly leading to fire or explosion, electrolyte spillage and electrical shock or electrocution. The hydrogen fuel cell system risks include electrical shock or electrocution and possible release of hydrogen gas (if tested with). Vehicle crash testing protection should be coordinated with the system or component manufacturer(s) suggestions. Precautions should be taken with the handling, transportation, and storage of the vehicle pre-crash and post-crash. This document was written to provide and an understanding of the risks and
Impact and Rollover Test Procedures Standards Committee
The special risks associated with conducting crash tests on E-vehicles can be divided into two main categories: (1) thermal activity inside the battery (resulting from electrical or mechanical abuse) may lead to energetic emission of harmful and/or flammable gases, thermal runaway, and potentially fire; and (2) the risk of electrocution. Procedures to ensure protection from all types of risk must be integrated into the entire crash test process. This SAE Information Report is intended to provide guidance in this endeavor using current best practices at the time of this publication. As both battery technology and battery management system technology are in a phase of expansion, the contents of this report must then be gaged against current technology of the time and updated periodically to retain its applicability and usefulness. The scope of this document is to provide an understanding of the risks and an overview of the techniques established to reduce the likelihood that an event

AMS CACRC Commercial Aircraft Composite Repair Committee
This procedure establishes a recommended practice for performing a Low Speed Thorax Impact Test to the Hybrid III Small Female Anthropomorphic Test Device (ATD or crash dummy). This test was created to satisfy the demand by the industry to have a certification test which results in peak chest deflection similar to current full vehicle, frontal impact tests. An inherent problem exists with the current certification procedure because the normal (6.7 m/s) thorax impact test has test results for peak chest deflection that are greater than those currently seen in full vehicle, frontal tests. The intent of this document is to develop a low speed thorax certification procedure for the H-III5F dummy with a 3.0 m/s impact similar to the SAE J2779 procedure for the H-III50M dummy.
