In a global economy, aviation, space and defense organizations are presented the challenge of producing and delivering safe and reliable products across a wide range of customer requirements and expectations. In an effort to address diverse quality requirements and expectations while also reducing costs throughout the supply chain, the AS9100 family of standards was developed by international aerospace industry representatives to standardize international aerospace quality management system requirements. This three-hour web seminar will provide a starting point for participants to gain an overall understanding of AS9100:2009 (Rev. C).
Training / Education
Internal audits are a requirement of the AS9100 Rev C standard and one of the fundamental requirements of the internal audit program is to verify the compliance of the organization’s quality management system to the AS9100 standard. Internal auditors must be knowledgeable of these requirements and the expectations as identified in the standard. In addition, the requirements of AS9101Rev D have significantly changed the way audits are expected to be performed in the Aviation, Space and Defense industries.

Tough times require searching for things that we can change and making them better. But so often problems are solved with 'band-aids' and not root cause solutions. This approach is getting too expensive and at best only helps companies tread water. To combat these issues and adopt a fresh approach, teams can use the methods and tools of Root Cause Problem Solving to first view problems as opportunities for improvement, identify root causes and implement solutions to prevent recurrence. Benefits include improved quality and customer satisfaction, reduced operation costs, and greater employee knowledge of work processes.

Securing the desired durability of suspension components is one of the most important topics for the vehicle designers because these components undergo multiaxial variable amplitude loading in the vehicle. Leaf springs are essential for the suspension system of trucks and should be considered as a security relevant part in the product development phase. In order to guide the engineers in the design and testing department, a simulation method was developed as explained in the paper “Bakir, M., Siktas, M., and Atamer, S., "Comprehensive Durability Assessment of Leaf Springs with CAE Methods," SAE Technical Paper 2014-01-2297, 2014”. In this new study, the main aim is to present the validation of this newly developed CAE method for the durability of leaf springs depending on the results from testing and measurement in the rough road and test bench.

With stringent emission regulations, many subsystems that abate engine tailpipe-out emission become necessary part for engines. With the increased levels of complexity, end users also require increased level of quality for modern engines. Among the spectrum of quality control methodologies, one extreme example is focused on very components’ quality to ensure the accumulative deviation is within predetermined limits. These measures tighten the component tolerance during manufacturing process and typically results in increased cost. Another extreme example is on the other side of the methodologies spectrum. The methodology is to tailor the engine calibration solution to offset the manufacturing difference. Although the tailored engine calibration solution reduces manufacturing cost for components, it increases the calibration and validation cost for engines. Given the cost and time constraints, system integration plays an important role in engine development.

All around the world, steps are being taken to improve the quality of our environment. Prominent among these are the definition, implementation, and attainment of increasingly stringent emissions regulations for all types of engines, including off-highway diesels. These more rigorous regulations have driven engine manufacturers to apply technologies like after-treatment, advanced air systems, and advanced fuel systems to reduce emissions. Fuel dispensed off-highway is routinely and significantly dirtier than fuel from on-highway outlets. Also, fuels used in developing countries can be up to 30 times dirtier than the average fuels in North America. Increased debris concentrations, coupled with the higher pressures and performance demands of modern fuel systems, combine to create life challenges greater than encountered with cleaner fuels. This can results in costly disruption of operations, loss of productivity, and customer dissatisfaction in the off-highway market.

Cylinder deactivation (CDA) is an effective method to adjust the engine displacement, for maximum output and improving fuel economy, by adjusting the numbers of active cylinders in the combustion engines. Switching Roller Finger Followers (SRFF) are an economic solution for CDA that minimize changes and preserve the overall width, height or length of Dual Overhead Cam (DOHC) engines. The CDA SRFF provides the flexibility of transferring or suppressing the camshaft movement to the valves influencing the engine performance and fuel economy by reducing the pumping losses. This paper addresses the performance and durability of the CDA SRFF system in meeting the reliability for modern automobile engines. Extensive tests were conducted to demonstrate the dynamic stability at high engine speeds, and the system capacity of switching between high and low engine displacement within one camshaft revolution.

The Indian automotive sector is experiencing a major shift, focusing predominantly towards the levels of quality, reliability and comfort delivered to the customer. Since the entry of global players into the market, there is a rising demand for timely product launches with utmost priority to reliability. In any vehicle, suspension plays a critical role in transferring the road inputs onto the vehicle components, therefore, responsible for both ride comfort and load transfer. Engine mount, being an integral part of this system, takes care of isolating the inertial forces between the engine and the chassis. This project details on how testing can aid in reducing the launch time as well as ensuring desired degree of reliability. It proposes a methodology to formulate a life model for the engine mount considering various combinations of predictor parameters affecting its performance over its design life.

Bench testing is commonly used to construct fatigue design curves, which are used for the durability and reliability assessment of engineering components subjected to cyclic loading. Several criteria, such as R90C90 and R99C50, are widely used in automotive industry to construct fatigue design curves for a typical testing sample allocation, i.e. two stress/load levels and 6 data points at each stress/load levels. In order to reduce the test sample size and associated testing cost, recently, a Bayesian statistics based design curve construction method has been successfully developed. The Bayesian method is based on a large amount of reliable historical fatigue test data, the associated probabilistic distributions of the mean and standard deviation of the failure cycles, and an advanced acceptance-rejection resampling algorithm.

The Global Brake Safety Council sees an increase in disc brake pads that are prematurely replaced before the end of the friction lining life cycle, due to: Rust related issues such as separation of friction lining from the disc brake shoe Fluctuation in critical dimensions A leading cause for both issues is the use of mill scale steel, or ‘black steel’ (non-pickled and oiled). In the North American aftermarket, as there are little or no steel specifications for disc brake shoes, black steel is increasingly used. GBSC conducted research of discarded disc brake pads from job-shops and engaged in discussions with metallurgists, major pad manufacturers and OE brake foundation engineers to identify root causes of premature pad replacement and the effects of black steel used for disc brake shoe manufacturing. Mill scale is embedded in and around the bond line of the friction lining and the disc brake shoe, causing a weaker bond, susceptible to rust jacking.

The aerospace industry is continually becoming more competitive. With an aircraft’s large number of components, and the large supplier base used to fabricate these components, it can be a daunting task to manage the quality status of all these parts in an accurate, timely and actionable manner. This paper focuses on an aircraft door assembly case study monitoring the process capability of machined parts at an aircraft OEM and their supply chain. Through the use of standardized measurement plans and statistical analysis of the measured output, the paper will illustrate how stakeholders can understand the process performance details at a workcell level, as well as overall line or plant performance in real time, in addition to automating standardized reporting. This ideal process begins in the product engineering phase using simulation to analyze the tolerance specifications and assembly process strategy, with one of the outputs being a production measurement plan.

Nowadays, growing complexity in digital systems forces electronic hardware designers to adopt Electronic System Level (ESL) design and verification approach from a high-level perspective. To assess the reliability of a digital hardware design towards cosmic rays effects, this paper proposes a verification methodology based on high abstraction level fault injection simulation using a library of primitives characterized at lower levels. Once created, the designer can reuse this library in order to obtain a reliability report. The novelty of this research resides in the capacity of using an accurate fault injection model in a highly abstracted system description. Combining this accuracy with the use of error pattern classification at low-level, brings a new perspective to the simulation-based fault injection field.

It has been lately established (see, e.g., [1]) that the continuing trend on miniaturization (Moore’s Law) in IC design and fabrication might have a negative impact on the device reliability, especially when it comes to deep submicron (DSM) technologies. These are characterized by etching thicknesses below 90nm. In order to understand and to quantify the physics underlying this phenomenon, it is natural to proceed from the experimental bathtub curve (BTC), an experimental reliability “passport” of a population of mass produced devices. As is known, this curve considers and reflects the combined effect of two irreversible processes: statistics-related mass-production process and reliability-physics-related degradation (aging) process. The first process results in a decreasing failure rate with time, while the second process leads to an increasing failure rate. It is this second process that should be of major concern to an IC designer and manufacturer.

I. 77330 Ozoir-la-Ferrière (France) brigitte.vasques@apextoolgroup.com Abstract: The drilling of multilayers composite stacks remains a common process in aerospace industry. Research of productive solutions such as one shot and dry drilling operations to avoid reaming and lubrication are contemplated by aerospace customers on titanium multilayers composite applications. Those solutions permit to reduce the number of finishing operation and drilling time. Special ADEs (advanced drilling equipment’s) machines are used to drill aircraft components in limited access areas. Parameters such as cutters, ADE machines, rigidity fixation, drill cutting conditions, chip fragmentation and extraction are related and influence the hole quality. Titanium (TA6V) thickness and cutting configuration influence the cutter wear development.
