    Development of a SysML Profile for Network Configurations in Safety-critical Systems
    (Modellierung 2022 Satellite Events, 2022) Hemmert, Andreas; Schweiger, Andreas
    The contribution describes an approach for defining avionics network architectures in an existing system model. To this end, a SysML profile is developed containing stereotypes to specify such a network. The corresponding model captures the network’s configuration. Such a configuration defines a network of a safety-critical complex system. As a result, systems engineers can use the profile in the systems development process with digital continuity. An example demonstrates the application of the profile in the model development.

    A Multi-Platform Small Scale Drone Demonstrator for Technology Maturation of Next Generation Avionic Functions
    (Software Engineering 2022 Workshops, 2022) Pickard, Michael; Ludewig, Philipp; Halbig, Jens; Krach, Bernhard
    The emerging need for new types of airborne platforms that are to be operated in a System-of-Systems context, e.g. like the European Future Combat Air System, drives the development and maturation of new technologies for the next generation of military aircraft. A special focus is on the utilization of swarms/teams of unmanned platforms which are envisaged to be operated in highly automated collaboration with manned platforms. To accelerate the development of those technologies Airbus Defence and Space has launched a small scale demonstrator project using customized Micro Air Vehicles 2. This enables modular and agile technology integration with low threshold to get new developments airborne. A major focus of the recent activities has been the establishment and enhancement of the development environment including test benches, mission software and ground control station. However, already a fi rst set of new technologies for formation management, collaborative navigation and sensor management as well as multiple sensors like a radio frequency emitter localization sensor and an industrial camera have been integrated and tested comprehensively. In summary it can be confi rmed that there are major benefi ts in the utilization of Micro Air Vehicles as rapid prototyping platform for avionics technology maturation.

    Partitioning and Task Transfer on NoC-based Many-Core Processors in the Avionics Domain
    (Softwaretechnik-Trends Band 31, Heft 3, 2011) Hilbrich, Robert; van Kampenhout, J. Reinier
    Networks-on-Chip (NoC) based many-core processors can not only increase system performance but also allow he integration of multiple functions on a single hardware platform. To consolidate functionality on many-core systems in safety-critical domains software partitioning is required to avoid the propagation of faults due to the use of shared resources. In this paper we propose extensions to well established single-core partitioning mechanisms to take novel architectural characteristics of many-core processors into account. In addition to fixed partitioning, we present flexible partitioning as an approach to improve resource utilization and fault tolerance using dynamic reconfiguration. Flexible partitioning requires task migration between cores via a shared resource - the NoC - which may endanger the required predictability. Therefore we empirically analyze a variety of task transfer mechanisms on a Tilera TILEPro64TM many-core processor regarding their potential for deterministic reconfiguration during run-time.

    Towards Enabling Level 3A AI in Avionic Platforms
    (Software Engineering 2023 Workshops, 2023) Zaeske, Wanja; Brust, Clemens-Alexander; Lund, Andreas; Durak, Umut
    The role of AI evolves from human assistance over human/machine collaboration towards fully autonomous systems. As the push towards more autonomy subsequently removes the reliance on a human overseeing the system, means of self supervision must be provided to enable safe operations. This work explores dynamic reconfiguration to provide resilience to unforeseen environmental conditions that exceed the systems capabilities, but also against normal faults. We focus on providing the means for this in an ARINC 653 compliant environment, since we target avionics platforms. Scheduling and communication are two major aspects of dynamic reconfiguration. Hence, we discuss multiple respective implementation approaches. The third pillar of reconfiguration, the process of deciding when to reconfigure is also investigated. Combining these yields the building blocks for a self-supervising system.

    A Universal Configuration Format for Avionics
    (SE 2024 - Companion, 2024) Chrysalidis, Philipp; Thielecke, Frank
    Avionics module configuration, especially in the face of advancing technologies, will become more complex as computational demands rise. This requires a robust and automated approach while adhering to industry standards. However, state-of-the-art configuration is still highly error-prone and suffers from various stakeholders working with unsynchronized and decentralized data. This causes unnecessary iterations, leading to delays in development. The Universal Configuration Format for Avionics (UCoF), integrated into the AvioNET framework, presents a forward-looking solution. UCoF, built upon a meta-model approach, strives to enhance the configuration process through model-based methods. It meets essential configuration management requirements and offers versatility by supporting the configuration of diverse avionic platforms. Combining essential data for configuring real avionics device families, implementation targets and network design grants users access to a comprehensive data set throughout the configuration process.
