This ARP provides an insight into how to approach a cost benefit analysis (CBA) to determine the return on investment (ROI) that would result from implementing a propulsion Prognostics and Health Management (PHM) system on an air vehicle. It describes the complexity of features that can be considered in the analysis, the different tools and approaches for conducting a CBA and differentiates between military and commercial applications. This document is intended to help those who might not necessarily have a deep technical understanding or familiarity with PHM systems but want to either quantify or understand the economic benefits (i.e., the value proposition) that a PHM system could provide.

This specification covers procedures for ultrasonic inspection of thin wall metal tubing of titanium, titanium alloy, and corrosion and heat resistant steels and alloys having nominal OD over 0.1875 inch (4.762 mm) with OD to wall thickness ratio of 8 or greater and wall thickness variation not exceeding + or - 10% of nominal.

This process has been used typically for locating internal defects, such as cracks, voids, seams, and other discontinuities, which may or may not be exposed to the surface, but usage is not limited to such applications.

PEM Fuel Cell Testing and Diagnosis covers the recent advances in PEM (proton exchange membrane) fuel cell systems, focusing on instruments and techniques for testing and diagnosis, and the application of diagnostic techniques in practical tests and operation. This book is a unique source of electrochemical techniques for researchers, scientists and engineers working in the area of fuel cells. Proton exchange membrane fuel cells are currently considered the most promising clean energy-converting devices for stationary, transportation, and micro-power applications due to their high energy density, high efficiency, and environmental friendliness. To advance research and development of this emerging technology, testing and diagnosis are an essential combined step. This book aids those efforts, addressing effects of humidity, temperature and pressure on fuel cells, degradation and failure analysis, and design and assembly of MEAs, single cells and stacks.

This document discusses, in broad and general terms, the subject of acoustical considerations in engine test cells. One of the primary purposes of an engine test cell is to control the noise emanating from the operating engine in order to reduce noise in the surrounding facility and community to acceptable levels. This is done by the design and installation of specialized acoustic elements and features, which need to be fully integrated into the overall test cell design. It should be further noted, that the requirements of acoustic control are critical to the proper operation of the engine, safety of plant equipment and personnel, and meeting local and legal noise requirements.

This SAE Aerospace Information Report (AIR) provides methodologies and approaches that have been used to install and integrate full-authority-digital-engine-control (FADEC) systems on transport category aircraft. Although most of the information provided is based on turbofan engines installed on large commercial transports, many of the issues raised are equally applicable to corporate, general aviation, regional and commuter aircraft, and to military installations, particularly when commercial aircraft are employed by military users. The word “engine” is used to designate the aircraft propulsion system. The engine station designations used in this report are shown in Figure 1. Most of the material concerns an Electronic Engine Control (EEC) with its associated software, and its functional integration with the aircraft. However, the report also addresses the physical environment associated with the EEC and its associated wiring and sensors. Since most of today’s transport category engines use dual-channel full-authority digital engine control (FADEC) systems, this is the configuration which is addressed.

Technician training is required to ensure that recommended procedures are used for service and repair of Mobile Air Conditioning (MAC) systems using R-744 and/or R-1234yf. Unique requirements for each refrigerant are detailed within this standard. Technicians may be trained in either or both refrigerants. The technician shall be trained to recognize which refrigerant is being handled, how to handle it safely and be equipped with the essential information, proper equipment and tools, which are unique to these refrigerants. This standard outlines minimum content requirements for such training programs. Training programs designed in accordance with this standard are not intended to ensure or assess the technical skills of technicians regarding the diagnosis and repair of motor vehicle air conditioners. Rather, the goal of such programs is to provide information to technicians about safely handling refrigerants.

This SAE Standard provides manufacturers, testing facilities and providers of technician training with a procedure for certifying compliance with the appropriate standards. Manufacturers or seller who advertise their products as Certified to an SAE J standard shall follow this procedure. Certification of a product is voluntary; however, this certification process is mandatory for those advertising meeting SAE Standard(s) requirements. Only certifying to this standard allows those claiming compliance to advertise that their product (unit), component, or service meets all requirements of the specific SAE standard. Certification of compliance to this and the appropriate standard and use of the SAE label on the product shall only be permitted after all the required information has been submitted to SAE International and it has been posted on the SAE web site. This process is mandatory for those advertising as being “Certified to SAE JXXXX [appropriate SAE Standard] requirements or any advertising or labeling language that implies such certification.

BSR (Buzz, Squeak and Rattle) is one of the oldest concerns in automobiles which directly reflect the build, assembly and manufacturing quality of a vehicle. In a cabin all the areas where there is relative motion between two components, such as trims, instrument panel and seats, are prone to squeak. This paper explains the study of seat squeak measurement and diagnosis which is a major concern for one of the products which is already in the market. Since squeak is a friction induced non stationary phenomenon, lot of effort was required to generate squeak in both component as well as vehicle level. At component level, electrodynamic shaker was extensively used for generation of squeak signals. In Vehicle level, driving through different road patterns, pave track and forced excitation on four posters are performed for generation of squeak signals. In this paper usage of wavelet and Zwikker loudness are explained for the diagnosis of seat squeak to identify the problematic frequencies. Results in both pave track condition and in four poster excitation method are presented.

Ground clearance plays an important role in Sports Utility Vehicles (SUV). Designers are good in designing their own systems but when it comes to integration of systems, the impact of one system on others and cascading effects become the major problems in full vehicle development. The test vehicle is a monocoque construction with power train in transverse (east-west) direction. Vehicle shudder is observed in lateral direction exciting the steering column, floor during the low gear power train run up in Wide Open Throttle (WOT) condition. The shudder is felt predominantly on the front half of the vehicle. Being a low frequency phenomenon with high energy it becomes critical and the phenomenon is easily perceivable by passenger. The paper discusses the measurement and analysis procedures to identify the root cause of shudder. Different modifications are tried out based on the analysis and an optimum solution is selected. The selected modification does not have any effect on other Noise Vibration and Harshness (NVH) attributes.

This SAE Standard establishes the definition of a normal all day rated operating load for loaders as defined in SAE J1057. This SAE Standard applies to wheel and crawler loaders taking only hydraulic lift capacity and tipping capacity into consideration. It is recognized that specific operating conditions may allow larger, or require smaller loads than the rated operating load. Some conditions could require more careful or restricted operation with the rated operating load. This standard is not to be construed as setting up test procedures or conditions.
