In this paper, we focus on satellite production lines and design and implement a digital twin simulation and verification system for them. This is to improve manual documentation efficiency and provide sufficient process controllability in the small satellites’ batch production and assembly testing. We built a layered architecture. This allows the system to dynamically interact with AIT data management systems, structured process systems, and equipment data by fusing multi-source data. We also develop functional modules that combine lightweight 3D model visualization, dynamic simulation engines, and hybrid scheduling optimization algorithms. These modules can perform twin simulation, execute processes, intelligently schedule production, manage work reporting, conduct intelligent analysis, trigger anomaly alarms, and perform system management. We also dynamically simulate complex workflows like satellite transfer and automated assembly. These workflows are then verified using 3D virtual scene modeling and physical engines. We use time-series analysis to improve scheduling accuracy and multidimensional dynamic monitoring and hierarchical response to enhance production stability. In practice, the system can provide visualized control over the full process of satellite production. This greatly improves assembly efficiency and process controllability. It can also be an extensible digital way for aerospace manufacturing. The use of hierarchical architecture design and multimodal data fusion can be further applied in the complex equipment intelligent manufacturing.

This document applies to the development of Plans for integrating and managing COTS assemblies in electronic equipment and Systems for the commercial, military, and space markets, as well as other ADHP markets that wish to use this document. For purposes of this document, COTS assemblies are viewed as electronic assemblies such as printed wiring assemblies, disk drives, servers, printers, laptop computers, etc. There are many ways to categorize COTS assemblies1, including the following spectrum: At one end of the spectrum are COTS assemblies whose design, internal parts2, materials, configuration control, traceability, reliability, and qualification methods are at least partially controlled, or influenced, by ADHP customers (either individually or collectively) or by industry standards. An example at this end of the spectrum is a VME circuit card assembly. At the other end of the spectrum are COTS assemblies whose design, internal parts, materials, configuration control, and qualification methods are not controlled, or controllable, in any way by ADHP customers (either individually or collectively) or by industry standards. An example is a disk drive targeted for an industry other than ADHP use. It is critical for the Plan owner to: (1) review and understand the design, internal parts, materials, configuration control, reliability, and qualification methods of all “as-received” COTS assemblies and their capabilities with respect to their application in the intended System and environment; (2) identify risks; and where necessary (3) take additional action to mitigate the risks associated with the performance and reliability of the COTS assembly in the ADHP system.

The purposeful integration of existing and emerging technologies into CM practice will enable collaboration with supporting systems and provide stakeholders access to authoritative and trusted data in a timely fashion at their desktop to help drive educated decision making. This lays to rest the misguided myth that CM and supporting systems operate at cross-purposes. What does it mean to have CM in a world of new initiatives and 2-week sprints (i.e., time-boxed work periods), multiple increments producing Minimum Viable Products (MVP) and synchronized with Model Based Systems Engineering (MBSE) while being digitally transformed? MBSE initiatives drive the jump from “2D” data to “3D” data, thereby becoming a Model-Centric practice. Products now enable technology to push the product lifecycle management process to new levels of efficiency and confidence. This mindset is evidenced by five major functions of CM, as discussed below, and described in EIA-649C.

The development of Digital Twin (DT) has become popular. A dominant description of DT is that it is a software representation that mimics a physical object to portray its real-world performance and operating conditions of an asset. It uses near real-time data captured from the asset and enables proactive optimal operation decisions. There are many other definitions of DT, but not many explicit evaluations of DT performance found in literature. The authors have an interest to investigate and evaluate the quality and stability of appropriate DT techniques in real world aircraft Maintenance, Repair, and overhaul (MRO) activities. This paper reviews the origin of DT concept, the evolution and development of recent DT technologies. Examples of DTs in aircraft systems and transferable knowledge in related vehicle industries are collated. The paper contrasts the benefits and bottlenecks of the two categories of DT methods, Data-Driven (DDDT) and Model-Based (MBDT) models. The paper evaluates the applicability of the two models to represent vehicle system management. The authors present their methodological approach on Predictive Maintenance (PM) development basing on reliable DT models for vehicle systems. This paper contributes to design, operation, and support of aircraft/vehicle systems.

Ethernet is widely used among consumer and commercial systems throughout the world, and it is well understood by all levels of end-users. Due to economies of scale, coupled with availability of industrial-grade devices, Ethernet has also become suitable, and often dominant, for many types of more rigorous applications. Unfortunately, industrial-grade Ethernet devices are often associated with high costs and complex network management and configuration requirements.

This document outlines a standard practice for conducting system safety. In some cases, these principles may be captured in other standards that apply to specific commodities such as commercial aircraft and automobiles. For example, those manufacturers that produce commercial aircraft should use SAE ARP4754 or SAE ARP4761 (see Section 2 below) to meet FAA or other regulatory agency system safety-related requirements. The system safety practice as defined herein provides a consistent means of evaluating identified risks. Mishap risk should be identified, evaluated, and mitigated to a level as low as reasonably practicable. The mishap risk should be accepted by the appropriate authority and comply with federal (and state, where applicable) laws and regulations, executive orders, treaties, and agreements. Program trade studies associated with mitigating mishap risk should consider total life cycle cost in any decision. This document is intended for use as one of the elements of project solicitation for complex systems requiring a systematic evaluation of hazards and mitigating measures. The Managing Authority may identify, in the solicitation and system specification, specific system safety requirements to be met by the Developer. These may include risk assessment and acceptance criteria, unique classifications and certifications, or mishap reduction needs unique to their program. Additional information in meeting program specific requirements is located in the Appendixes.

This Aerospace Information Report (AIR) has been prepared by the Systems Applications and Requirements Subcommittee of SAE Committee AS-2. It is intended to provide guidance primarily, but not exclusively, for specifiers and designers of data communication systems for real time military avionics applications within a platform. The subject of high speed data transmission is addressed from two standpoints: (1) the influence of developments in technology on avionics architectures as a whole and (2) the way in which specific problems, such as video, voice, closed loop control, and security may be handled. While the material has been prepared against a background of experience within SAE AS-2 relating to the development of a family of high speed interconnect standards, reference to specific standards and interconnect systems is minimized. It should be noted, however, that many of the concepts described require interconnect systems with advanced operational and performance characteristics, such as those developed by SAE AS-2.

The purpose of this document is to establish the requirements for Real-Time Communication Protocols (RTCP). Systems for real-time applications are characterized by the presence of hard deadlines where failure to meet a deadline must be considered a system fault. These requirements have been driven predominantly, but not exclusively, by aerospace type military platforms and commercial aircraft, but are generally applicable to any distributed, real-time, control systems. These requirements are primarily targeted for the Transport and Network Layers of peer to peer protocols, as referenced in the Open System Interconnect Reference Model (2.2.1 and 2.2.2), developed by the International Standards Organization (ISO). These requirements are intended to complement SAE AS4074 (2.1.1) and AS4075 (2.1.2), and future SAE communications standards. Although information transfer objectives herein concentrate primarily on digital data flow attributes, efforts have been made such as not to preclude sensor/video and voice information transfers. This document provides evaluation criteria for selecting viable alternatives for a real-time communications protocol standard.

ABSTRACT Communications has come a long way from the two dimensional model provided by voice and data. Today complete situational awareness requires bringing a third dimension, video, into the mix. Implementing this unified view into today’s military vehicles calls for a unit with a well thought out design that interfaces thoroughly with other equipment and minimizes SWAP-C impact. This paper addresses the efficient convergence of video with existing voice and data presenting unified communications into a single SWAP-C device.

Designing the whole12OFHD0614_016/14/2012
Connecting model-based system engineering through PLM tools to CAD, FEA, and physical test is on the horizon. System-level modeling and simulation- tools for complete vehicle behavior-are about to expand, according to Derek Wright, Product Manager for Maplesoft. “A vehicle, like a front-end loader, has specific performance it must meet to be attractive in the marketplace. These requirements are getting both more difficult and interrelated,” he explained in a discussion with SAE Magazines. A front loader, for example, must be stable, safe, lift heavy loads, and use fuel efficiently. “If one part of that vehicle system fails to meet those requirements, it affects everything it is connected to,” said Wright. With the growing use of mechatronics, and its complexity, engineers that once could work in isolation must find a way to collaborate. All disciplines need a practical way to work together. System-level modeling and simulation software such as MapleSim from Maplesoft are designed to help engineers do just that. “You are going to see full system-level performance and analysis at all stages of the product design cycle,” said Wright. The collaboration net will need to expand beyond engineering. “We are moving towards bidirectional connectivity with the CAD environment, for example. That is going to be very important in the future,” he says. Why? According to him, using CAD to create simplified models for system-level models is vital to tame computational complexity. Computational complexity is nonlinear; only simplified models can compute a solution in a reasonable time. For example, so-called lumped-parameter models simplify a mechanical system to its essence. “You need to use CAD to create lumped-parameter models without losing the connectivity if you adjust the system model,” he explained. “The CAD guy does not want to know the lumped-parameter model. The lumped-parameter guy does not want to know all of the CAD detail. We need one model that I can look at with different lenses.”

A Quantitative Risk Analysis for AeroMACS Network Security in SESAR11VATC301013/16/2012
The growing need for an efficient worldwide airspace system management, generated by an increasing traffic load, requires new capabilities for air-ground data communication technologies. In order to cope with these requirements, the Federal Aviation Administration (FAA), EUROCONTROL, and the International Civil Aviation Organization (ICAO) have jointly made specific recommendations for candidate technologies for the airport surface communication network. In the SESAR project, the Aeronautical Mobile Airport Communication System (AeroMACS) technology is being developed in such a way to provide next generation broadband and wireless data communications for airport surface applications (i.e. Air Traffic Control ? ATC, Airline Operational Communications ? AOC, and surface vehicles services). As the airport surface communication system involves many heterogeneous application flows, digital information security has been considered as among the highest priority concerns in the air transport industry. Indeed, since AeroMACS is based on IEEE 802.16e/802.16-2009 standards, it inherits some security flaws specific to the WIMAX technology. Thus, a network risk analysis should be conducted in order to properly design and deploy a secure airport surface communication system, where interconnected aircraft, pilots, air traffic controllers, airline and airport operators can reliably communicate. To mitigate these security issues, the European Sky ATM Research (SESAR) technological and operational program is working under the 15.2.7 Work Package to study the AeroMACS network security using an original risk propagation based quantitative assessment methodology. Indeed, risk assessment has been considered as an essential technique in evaluating the security of network information systems. Many proposals have been made in this area to design new approaches allowing administrators and engineers to analyze the impact of any attack that could target their systems. Nevertheless, there is a lack of quantitative techniques and methods which take into account the inherent characteristics of a network such as interconnection between nodes. Besides, those standards and methods are related to information security in general and thus, are not entirely appropriate for the specific context of aeronautical communications. As an example, Aeronautical Radio Incorporated (ARINC) introduced in 2005 the ARINC 811 report which presents a commercial aircraft information security concepts of operation and process framework, but the presented risk assessment approach is static and evaluates damages produced by threats qualitatively, making results somewhat subjective. Thus, in this paper, we present a new approach for network security assessment that measures quantitatively the network risk level based on critical aspects such as the impact of a successful attack on a node and the risk propagation of that attack within the AeroMACS network. Rigorous validation experiments have been conducted using real statistics and vulnerability data from the National Vulnerability Database (NVD) and the network vulnerability scanning tool NESSUS. We specifically focused on AeroMACS vulnerabilities, and a network risk study was conducted for different predefined scenarios. Finally, a comparison between network risks for each scenario is made and some security guidance is given either to enhance the AeroMACS security features or to improve the end to end security using some additional mechanisms such as certificate-based authentication.

Using SCADE System for the Design and Integration of Critical Systems11VATC407023/14/2012
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. SCADE System avoids duplication of efforts and inconsistencies between system structural descriptions made of SysML Block Definition Diagram (BDD) and Internal Block Diagram (IBD), and the full software behavioral description designed through SCADE Suite models. Once the system description is completed and checked, the individual software blocks in the system can be refined in the form of models in SCADE Suite or in the form of manually developed source code. Automatic and DO-178B Level A-qualified code generation can then be applied to the SCADE Suite models. Moreover, the SCADE System description can be used as the basis to develop scripts that will automatically integrate the complete application software. Presenter Thierry LeSergent

Toolbased Calibration of the OBD Manager10VARANN1312/21/2011
At the moment the documentation of failure inhibition matrices and the fault path management for different controller types and different vehicle projects are mainly maintained manually in individual Excel tables. This is not only time consuming but also gives a high potential for fault liability. In addition there is also no guarantee that the calibration of these failure inhibition matrices and its fault path really works. Conflicting aims between costs, time and fault liability require a new approach for the calibration, documentation and testing of failure inhibition matrices and the complete Diagnostic System Management (DSM) calibration. The standardization and harmonization of the Diagnostic System Management calibration for different calibration projects and derivates is the first step to reduce time and costs. Creating a master calibration for the conjoint fault paths and labels provides a significant reduction of efforts. The failure inhibition matrix and fault path documentation can be automated with a tool, which uses a data set and non calibratable ECU configurations to create a document that satisfies the authority requirements and contains an overview of the interdependences of all fault paths. In order to accomplish this, the already established matrices can be used to create a master inhibition matrix that can then be compared with inhibition configurations in current calibration projects. The differences between the ?Master Calibration? (MC) and a derivative calibration can be detected and visualized with the help of powerful comparison features. If necessary, recognized problems can be efficiently resolved and implemented into the derivative calibration either manually or automatically. Fault paths that do not exist in the ?Master Calibration? can be found very quickly and than calibrated in a derivate specific manner. Presenter Markus Riener, AVL LIST GmbH
