... Such a wirelessenabled AHM can provide timely feedback to an onboard computer via in-aircraft communications or to off-board units via A2I, enabling the shift to an automated, real-time and proactive process. An example of a structural health monitoring application is shown infigure 2.23 below[61]. ...
... Structural Health Monitoring Application[61] Agile Air Traffic Control (ATC): The highly centralized architecture of current ATC leads to inefficiencies, reduced traffic handling capacity and lack of fault tolerance. The eenabled airplane presents several opportunities to decentralize ATC functions and share traffic control tasks, such as navigation and aircraft safe separation, with the ground controllers.A recent example is the Automated Dependent Surveillance Broadcast initiative (ADS-B) ...
This dissertation was written as part of my MSc degree in Cybersecurity at the International Hellenic University. More specifically, this paper critically examines the cybersecurity aspects and requirements of aerial networks, being formed between aircraft and other flying vehicles and the ground, including Air Traffic Control services, operators and users. It does that in the general context of the currently evolving aviation industry that strives to incorporate new basically wireless communication and networking technologies to enhance automation and efficiency. To introduce the unfamiliar reader to the aviation operational environment and the aspects of cybersecurity, this thesis provides an introductory description of the general context of the aviation industry and its evolution, as well as the challenges it faces with regards to cybersecurity that shape its evolution. The examination of a real world scenario as a test case was attempted next as an example of a cybersecurity aware design method. The scenario involves the development of a new air traffic control service similar to ADS-B. The system addresses the need to incorporate small aircraft and UAVs into the Air Traffic Management System and is based on low consumption wireless protocol LoRa and the Internet of Things (IoT) concept. The system was developed as a proof of concept and was subsequently analyzed to assess the threats and risks involved. Contingency measures for the hardening of the system were proposed and used to update the design. Finally, the paper studies more closely some of the measures proposed, with focus on the wireless physical level security. The use of encryption in this layer, as part of the modulation as well as Multi Input Multi Output (MIMO) techniques, is explored through simulations and possible advantages and disadvantages are identified.
... These information are detailed enough to plan smaller maintenance activities on the ground even before the aircraft has landed at its destination. [23,26] Likewise, the US Airforce uses information about each flight mission of each airframe and applies, for example the encountered g-forces, to a digital representation of the specific airframe to document its sate as well as improve the maintenance planning. [21,27] The presented concepts show that there are multiple use cases and already some partly implementations of Digital Twins in today's aviation, but also that there are more possibilities to be explored, and fields of applications to be implemented. ...
In this paper an approach to combine the basic concept of Digital Twins with research in product family development applied to civil aviation is presented. Concomitant benefits but also challenges regarding the management of information are introduced as well as the possibility to solve them by using the tools and methods of Model-Based Systems Engineering. As this conjoins three different topics, the basics of each of them in reference to the approach is introduced before they are subsequently combined. In the process, respective past and future research is presented as well.

Current design rules are analyzed and challenged by considering better damage-detection capabilities offered by structure health monitoring systems. The weight-saving potential associated to the integration of such sensing systems is discussed with regards to structural and structure health monitoring system design. Three prospective scenarios are analyzed and considered in a specific use case. According to the most promising scenario (i.e. robust detectability of damages larger than 300 mm2), structural weight reductions of approximately 9% can be achieved. Considering the weight added by the structure health monitoring system, effective weight savings in the order of 5% are achievable. Although this potential is rather modest, applying structure health monitoring systems on structures mainly driven by the damage tolerance criterion is expected to provide reductions far beyond 5%.
Die Bachelorarbeit beschäftigt sich mit der Entwicklung einer Demonstratorplattform für den Zweck der Verifikation und Präsentation von neuartigen Forschungsthesen aus dem Bereich der Luftfahrtinstandhaltung mit Schwerpunkt Kosten- und Entwicklungsaufwandminimierung: Es wird ein aus einem Gerüst, Abdeckungen, Stromverteilung sowie einem Halterungssystem bestehendes mechanisches Trägersystem für modulare Avionik -Komponenten konzipiert und erstellt. In dieses System wird ein modularer, elektronischer Aufbau mit Grundbausteinen wie Raspberry PIs, Arduinos, Displays, Sensoren, CAN-USB Adapter sowie dem ROS-Framework integriert. In diesem Aufbau werden die luftfahrtspezifischen Komponenten Electronic Instrument System, Air Data Inertial Reference Unit, Tire Pressure Indicating System und Braking and Steering Control Unit modellhaft nachgebildet und zusammen mit der Demonstratorplattform aus Sicht eines Luftfahrtforschers verifiziert.
