Counterfeit Electronic Parts and Their Impact on Supply Chains

2014-10-20
Electronic parts are used throughout industry to run everyday products, such as cell phones, and also highly technical products, such as aircraft, missiles, and spacecraft. Unlike cell phones, which are often replaced every year, the highly technical products may remain in service from 20 to more than 80 years. But what happens if the original electronic part, with a life cycle of 18 months, is no longer available? Some manufacturers have discovered that they have unwittingly purchased counterfeit ones. Counterfeit Electronic Parts and Their Impact on Supply Chains examines how these items are negatively affecting the aviation, spacecraft, and defense sectors and what can be done about it.

Business Model for Successful Commercialization of Aircraft Designs

2012-03-21
In any new aircraft development program there are many important design decisions that determine profitability potential. The key to making new aircraft profitable is to design features that will command more money than the cost to provide them within the market's ability to absorb them. The business model in this paper shows how to predict or find: 1) the costs to provide various aircraft features; 2) the values that aircraft buyers place on these features; 3) the amount of money that buyers have to commit to them, 4) the open spaces in the market in which to place new designs and 5) the predicted profits from new designs. In this process, this paper extends previous work on the law of value and demand, which states that attributes determine value; value determines price; and that price determines demand. This four-dimensional, non-negative system hosts a business model that describes the features needed to enable aircraft designs to go from concepts to profitable assembly lines.

Mastering the ARINC 661 Standard

2012-03-19
By introducing the concept of a separation between graphics and logic, interpreted run time architecture, and defined communication protocol, the ARINC 661 standard has addressed many of the concerns that aircraft manufacturers face when creating cockpit avionics displays. However, before kicking off a project based on the standard, it is important to understand all aspects of the standard, as well as the benefits and occasional drawbacks of developing with ARINC 661 in mind. This white paper will first provide an overview of ARINC 661 to clarify its concepts and how these relate to the development process. The paper will also describe the benefits of using a distributed development approach, and will outline practical, real world considerations for implementing an ARINC 661-based solution. Finally, readers will learn how commercial tools can be used to simplify the creation of displays following the standard to speed development and reduce costs.

Tailored Conversion Coatings for Enhanced Adhesion to Metal

2012-03-21
The use of silane chemistries tailored to promote the adhesion of performance and appearance coatings to metal substrates are requiring new methodologies for measuring, approving, and implementing on commercial aircraft. Engineering performance, lean manufacturing, environmental and employee safety considerations are driving the commercial aerospace industry to replace long standing conversion coating materials and processes. Tailored silane chemistries such as Boegel are being considered for many of these applications. Silanes work by reacting with metal oxides providing a strong covalent bond, cross linking to form a tough barrier and have an organic functional group tailored to react with the specific resin system in the subsequent coating. Traditionally conversion coatings such as anodize and chromate conversion coating performance is validated based on meeting standalone requirements.

Airbus - EMAs for Flight Controls Actuation System - An Important Step Achieved in 2011

2012-03-21
A significant step is achieved on the flight control actuation system toward the more electrical aircraft through the Airbus A380, A400M and the A350 development phase ongoing. The A380/A400M/A350 features a mixed flight control actuation power source distribution, associating electrically powered actuators with conventional FlyByWire hydraulic servocontrols. In the scope of the preparation of the future Airbus Aircraft, this paper presents the perspectives of the use of the EMA technologies for the flight control systems in the more electrical aircraft highlighting the main technical challenges need to treat: jamming susceptibility, ?on board? maintenance reduction, Operational reliability increase, power electronics and power management optimization, and regarding the environmental constraints, the predicted performances; the benefits associated to the optimized utilization of on-board power sources.

Study of Exit Burr Formation and Exit Burr Reduction in Automated Drilling of Titanium Stacked With Carbon Fiber Composite

2012-03-16
With the growing use of carbon fiber composite structure in Aircraft Manufacturing, the challenge of drilling carbon fiber stacked with Titanium has become a focus point. Due to the abrasive nature of the carbon fiber (CF), cutting tool life is relatively short when drilling carbon fiber stalked with Titanium. A common drill wear indicator is exit burr formation in the Titanium. As drilling tools wear due to the abrasive nature of the CF, the exit burr in the in the Titanium increases. This study seeks to understand the factors that lead to tool wear and exit burr formation. A correlation may be made relating drilling thrust forces with exit burr formation. Different cutting tools geometries and materials are studied using a high speed camera to attempt to understand the factors influencing exit burr formation. Findings are optimized and tested. Decreasing exit burr in the drilling of CF and Titanium may increase tool life thereby reducing tool costs to airframe manufacturers.

How to Address the Existing and Future Requirements of ASFC: The Safe and Secure Virtualization RTOS Approach

2012-03-21
With the increase of functions in the next generation of aircrafts, it has become very important to address reconfigurability. The bottom line is that space and weight available for critical computers in an aircraft remain mostly unchanged. These new functions imply more computation power and so more redundant elements for safety. CPU power has been increased but the latest evolution with the new multi-core CPU's introduces additional difficulties in terms of certification. IMA first generation was the first answer to address some of these problems by enabling the concentration of several certified critical functions in the same physical computer. However, up to now, such implementations were very static and did not scale very well with the increase of functions need for the next generation aircraft. That?s why the avionics industry is looking for improvement of existing solutions and must work on what would be the next generation of IMA (IMA-NG).

Orbital Drilling Machine for One Way Assembly in Hard Materials

2012-03-23
In Aeronautic industry, when we launch a new industrialization for an aircraft sub assembly we always have the same questions in mind for drilling operations, especially when focusing on lean manufacturing. How can we avoid dismantling and deburring parts after drilling operation? Can a drilling centre perform all the tasks needed to deliver a hole ready to install final fastener? How can we decrease down-time of the drilling centre? Can a drilling centre be integrated in a pulse assembly line? How can we improve environmental efficiency of a drilling centre? It is based on these main drivers that AIRBUS has developed, with SPIE and SOS, a new generation of drilling centre dedicated for hard materials such as titanium, and high thicknesses. The first application was for the assembly of the primary structure of A350 engine pylons. The main solution that was implemented meeting several objectives was the development of orbital drilling technology in hard metal stacks.

A350XWB Fiber Placement Spars; From R&D Conception Phase to Serial Production

2012-03-23
At the end of 2006, two MTorres engineers visited the plant of Airbus UK in Filton receiving a new challenge: Find a more efficient way to manufacture Carbon Fiber Spars for the new A350 program. The range of possibilities were wide: manual infusion methods (RTM, RIM, RFI...), Automatic Taping & hot forming, or the new technology proposed, Fiberplacement or AFP. Two (2) options were considered: hot forming+ATL and AFP (both using prepeg technology.) The usage of a flat lay-up + hot forming technology was used in the only Airbus program that used carbon fiber for the wing manufacturing so far, the A400M. The expected greater complexity of A350 spar created doubts on the feasibility of using the above process, while the AFP technology, consisting of laying up directly on the final shape of the spar, also raised questions of technical feasibility, apart from the economic ?business case?, in case the productivity of the cell was not big enough.

Subjective and Objective Assessment Of Vehicle Handling Performance

2000-06-12
2000-05-0247
The results of a research programme involving a three pronged approach to vehicle handling - involving a series of experimental measurements, subjective assessments and modelling predictions (1) - were presented at FISITA 98 in Paris. From the analysis of this extensive range of results it was concluded that although some significant areas of correlation e.g. transient step steer responses, were identified, there was still some way to go before the confidence levels such as those associated with aircraft practice could be achieved. Consequently, a subset of the results - in particular those associated with the results frequency response measurements - have been analysed using a technique proposed originally in 1990 at Mitsubishi (2). This approach is called the “Four Parameter Evaluation Method” and uses a rhombus pattern graph to plot out steady state yaw velocity gain, natural frequency of yaw velocity, damping of yaw velocity response and phase delay at 1 Hz lateral acceleration.

A large number of tests were made in the altitude laboratory of the Bureau of Standards, using aircraft engines. The complete analysis of these tests was conducted under the direction of the Powerplants Committee of the National Advisory Committee for Aeronautics. Many of the engines were of the same make, differing in compression ratio or dimensions. The testing program included determinations of the brake-horsepower at various speeds and altitudes, or air densities, and the friction power, or the power required to operate the engine with no fuel or ignition at various speeds and air densities, with normal operating conditions of oil, water and the like. Some tests included determination of the effect of change of mixture ratio and of air temperature, and of different oils. The difficulties caused by the necessity of using indirect methods to ascertain the effect of various factors are outlined. The test analyses and curves are presented.

Research is being conducted at the Georgia Tech Research Institute (GTRI) to develop advanced aerodynamic devices to improve the performance, economics, stability, handling and safety of operation of Heavy Vehicles by using previously-developed and flight-tested pneumatic (blown) aircraft technology. Recent wind-tunnel investigations of a generic Heavy Vehicle model with blowing slots on both the leading and trailing edges of the trailer have been conducted under contract to the DOE Office of Heavy Vehicle Technologies. These experimental results show overall aerodynamic drag reductions on the Pneumatic Heavy Vehicle of 50% using only 1 psig blowing pressure in the plenums, and over 80% drag reductions if additional blowing air were available. Additionally, an increase in drag force for braking was confirmed by blowing different slots.
