Abstract:
In order to avoid the complex mathematical modeling and ensure the reliability of avionics system verification, this paper has designed an interfaces emulation and verification platform of avionics system based on QAR data. Platform includes 2 parts: Emulator and Simulator. Simulator generates the flight environmental data which is come from QAR and transforms the data into excitation signal of devices. Emulator emulates the interface features of avionic devices according to the ICD and can be replaced with real devices. By comparing the actual input-output data of devices with QAR theoretical data, this platform can evaluate the running performance of avionic systems or devices and the rationality of the ICD.

Abstract:
The avionics systems of state-of-the-art commercial aircraft have become increasingly complex and sophisticated, in order to meet the ever increasing performance and reliability requirements. With the capability of the avionics technology improving by an order of magnitude every few years, it is envisaged that the current philosophy of one box-per-function will soon reach its limits in terms of cost, functionality, reliability, and certification. The proposed solution is the integrated systems configuration, using distributed processing, where the computational resources are shared between many functions, therefore improving the reliability, availability, survivability, and extensibility of the overall system. Futhermore, this approach will also provide the potential for reducing the acquisition, maintenance and operating costs. The paper discusses the limitations of the current avionic system's architecture in dealing with the high levels of functionality required by the state-of-the-art aircraft, and discusses the philosophy of the integrated modular avionics, which represents a change in philosophy of avionics design to a decentralized, distributed architecture that allows interchangeable components within a distributed aircraft avionic system. The paper also addresses a number of specific issues considered necessary for the implementation of a decentralized, distributed architecture such as data bus requirements, electromagnetic and radio frequency prevention, and fault tolerance But it also argues that for true systems integration, a new culture is required based on open systems with a set of inherent quality features such as conformance, robustness, extendibility, compatibility, and reusability built into the architecture.

Abstract:
Fibre Channel (FC) as a Universal Avionics Network (UAN) candidate solution for the advanced integrated avionics systems can enable high-bandwidth, low-latency, high-reliability and hard real-time communication on aircraft platforms spanning military and commercial applications. Fibre Channel Avionics Environment-Anonymous Subscriber Messaging protocol (FC-AE-ASM) is one of the five high level protocols in fiber channel avionic environment which is used to transport command, control, signal processing and sensor / video data of the aircraft[1,2].The objective of this paper is to conduct a modeling and simulation on the performance of the FC–AE-ASM network. Through modeling the message transmission of the FC-AE-ASM with accompanying Eclipse, some network performance parameters such as bandwidth, throughput and end-to-end message delay can be gained and analyzed.

Abstract:
In order to achieve high safety standards, avionic software needs to be developed with very high requirements regarding safety, reliability, and determinism as well as real-time constraints, which are often in conflict with the development of maintainable software systems. Nevertheless, the ability to change the software of an airplane is of increasing importance, since it consists of a multitude of partially hardware-specific subsystems which may need replacement during a plane’s lifespan of typically numerous decades. Thus, as a first step towards optimizing maintainability of avionic software we have benchmarked the cabin software of a commercial airliner with common software metrics. Such a benchmarking of avionic software contributes valuable insights into the current practice of developing critical software and the application of software metrics in this context. We conclude from the obtained results that it is important to pay more attention to long-term maintainability of aviation software. Additionally we have derived some initial recommendations for the development of future avionic software systems.

Abstract:
In modern combat aircrafts, avionics integrated systems play an increasingly important role. Bus test and analysis system is used as a testing platform for the testing, debugging, maintenance and monitoring of airborne electronic equipment, which could rapidly detect and identify the working status of the bus. This paper discusses the general avionics data bus test system design and implementation, which focuses on the test system design, system management, software development, and the bus information flow management of the whole system. The universal test and analysis system is based on the bus test analysis platform of ICD database that can effectively test ARINC429 bus and 1553B bus. Through integrating the platform into the simulation system, it can complete the closed-loop test of the integrated avionics simulation test system, analyze the state changes of various information flows during the process of bus communication, test and verify the active status and logical sequence of avionic fire control test systems, which has achieved very good results in the practical engineering applications.

Abstract:
This paper brings out the design of a fault-tolerant power supply unit for the aircraft-store interface. This switched mode power supply provides multiple 30 V regulated and isolated DC outputs required for pre-launch preparations and auto-launch operations of avionic sub-systems in a store. 3Ø-115V-400Hz-AC supply as well as 27V-DC supply are available from a fighter aircraft for powering up of any store. Power (wattage) output from 27V/10A DC is inadequate to power up various onboard avionic sub-systems in guided stores involving seekers and other avionics. Hence, it is planned to convert available high power 3Ø-115V-400Hz-AC supply for applications requiring higher wattages (of the order of 500 watts or more). This power supply provides multiple output options of 30V regulated and isolated DC supply with multiple input supplies from Aircraft, viz. 3Ø-115V-400Hz-AC, 1Ø-115V-400Hz-AC and 27V DC. One of the outputs provided is with hold-up capacitors, to cater for any input power interruptions as per requirements of MIL-STD-704F and GOST-19705-89 standards. This power supply is a ready-to-connect device and essentially consists of housing, components of DC to DC conversions, EMI/EMC filters, solid state power controllers, control switches, and control circuitry for monitoring signals.

Abstract:
The modern military aircraft can be defined as a System of Systems (SoS); several distinct systems operating simultaneously across boundary interfaces. As the on-board subsystems have become more complex and diverse, the development process has become more isolated. When considering thermal management of distributed heat loads, the aircraft has become a collection of individually optimised components and subsystems, rather than the implementation of a single system to perform a given task. Avionic thermal management is quickly becoming a limiting factor of aircraft performance, reliability and effectiveness. The challenge of avionic thermal management is growing with the increasing complexity and power density of avionic packages. The aircraft relies on a heat rejection growth capacity to accommodate the additional through-life avionic heat loads. Growth capacity is defined as an allowable thermal loading growth designed into the system by the underutilisation of spatial and cooling supply at aircraft introduction; however, this is a limited resource and aircraft subsystem cooling capability is reaching a critical point. The depleted growth capacity coupled with increased avionic power demands has led to component thermal failure. However, due to the poor resolution of existing data acquisition, experimental facilities or thermodynamic modeling, the exact inflight-operating conditions remain relatively unknown. The knowledge gap identified in this work is the lack of definitive methodology to generate high fidelity data of in-flight thermal conditions of fast-jet subsystems and provide evidence towards effective future thermal management technologies. It is shown that, through the development of a new methodology, the knowledge gap can be reduced and as an output of this approach the unknown system behaviour can be defined. A multidisciplinary approach to the replication, analysis and optimisation of a fast-jet TMS is detailed. The development of a new Ground Test Facility (GTF) allows previously unidentified system thermal behaviour to be evaluated at component, subsystem and system level. The development of new data to characterise current thermal performance of a fast jet TMS allows recommendations of several new technologies to be implemented through a component led integrative system optimisation. This approach is to consider the TMS as a single system to achieve a single goal of component thermal management. Three technologies are implemented to optimise avionic conditions through the minimisation of bleed air consumption, improve avionic reliability through increased avionic component isothermalisation and increase growth capacity through improved avionic heat exchanger fin utilisation. These component level technologies improved system level performance. A reduction in TMS bleed air consumption from 1225kg to 510kg was found to complete a typical flight profile. A peak predicted aircraft specific fuel consumption saving of 1.23% is seen at a cruise flight condition because of this approach to avionic thermal management.

This defines a standardized execution and communication support in order to reduce the complexity of the physical architecture. Nevertheless, due to the sharing of resources, this reduction of complexity is opposed by an increased difficulty in application conception and integration, which necessitates dedicated tools for assisting system designers. This thesis’ contributions concern two major resource allocation problems: i) the multiprocessor scheduling of strictly periodic tasks and ii) the routing of messages exchanged between the avionic functions. The first problem was formulated using integer linear programming so as to guarantee a maximum evolution potential for the task execution durations. The inefficiency of this exact approach for large problem instances led us to develop an original heuristic, inspired from Game Theory, and further enhance it with a multi-start algorithm. The routing problem was formulated as an optimization one so as to minimize the maximum link loads. Two methods were proposed for this purpose, the first is exact based on node-link formulations, and the other is a two phase heuristic based on link-path formulations

Abstract:
In the space industry a lot of efforts is put towards verification and validationof the different parts of the spacecraft. This is a costly process and cause initial friction when trying to introduce new technology within the field. One of the demanding systems to validate and test is the on-board software. To makethe process of evaluation and testing of new technologies easier, the EuropeanSpace Agency has put effort towards creating an end-to-end avionic test bench containing four different simulators. In this test bench a fictional mission called EagleEye was constructed. EagleEye is a representative low-cost &amp; low-powerEarth observation mission to create a fictive environment to perform system tests. As of 2018 the mission still lacked the functionality of orbital maintenance. However, during the autumn of 2018 the system had the orbital control modeintroduced to the Functional Engineering Simulator in the MATLAB Simulink environment.This was one process for the integration of the orbital control mode, thesystem still had three additional simulator environments requiring the implementation: Functional Validation Test-Bench, Software Validation Facility andReal-Time Test-Bench. This thesis covers the implementation within the first two simulators mentioned. The work was carried out during the spring of 2019 and showed that the simulators were updated successfully and verified. Development of the simulator will continue as there are still things to be done.

Abstract:
Avionics and space industries are struggling with the adoption of technologies like multi-processor system-on-chips (MPSoCs) due to strict safety requirements. This thesis propose a new reference architecture for MPSoC-based mixed-criticality systems (MCS) - i.e., systems integrating applications with different level of criticality - which are a common use case for aforementioned industries. This thesis proposes a system architecture capable of granting partitioning - which is, for short, the property of fault containment. It is based on the detection of spatial and temporal interference, and has been named the online detection of interference (ODIn) architecture. Spatial partitioning requires that an application is not able to corrupt resources used by a different application. In the architecture proposed in this thesis, spatial partitioning is implemented using type-1 hypervisors, which allow definition of resource partitions. An application running in a partition can only access resources granted to that partition, therefore it cannot corrupt resources used by applications running in other partitions. Temporal partitioning requires that an application is not able to unexpectedly change the execution time of other applications. In the proposed architecture, temporal partitioning has been solved using a bounded interference approach, composed of an offline analysis phase and an online safety net. The offline phase is based on a statistical profiling of a metric sensitive to temporal interference’s, performed in nominal conditions, which allows definition of a set of three thresholds: 1. the detection threshold TD; 2. the warning threshold TW ; 3. the α threshold. Two rules of detection are defined using such thresholds: Alarm rule When the value of the metric is above TD. Warning rule When the value of the metric is in the warning region [TW ;TD] for more than α consecutive times. ODIn’s online safety-net exploits performance counters, available in many MPSoC architectures; such counters are configured at bootstrap to monitor the selected metric(s), and to raise an interrupt request (IRQ) in case the metric value goes above TD, implementing the alarm rule. The warning rule is implemented in a software detection module, which reads the value of performance counters when the monitored task yields control to the scheduler and reset them if there is no detection. ODIn also uses two additional detection mechanisms: 1. a control flow check technique, based on compile-time defined block signatures, is implemented through a set of watchdog processors, each monitoring one partition. 2. a timeout is implemented through a system watchdog timer (SWDT), which is able to send an external signal when the timeout is violated. The recovery actions implemented in ODIn are: • graceful degradation, to react to IRQs of WDPs monitoring non-critical applications or to warning rule violations; it temporarily stops non-critical applications to grant resources to the critical application; • hard recovery, to react to the SWDT, to the WDP of the critical application, or to alarm rule violations; it causes a switch to a hot stand-by spare computer. Experimental validation of ODIn was performed on two hardware platforms: the ZedBoard - dual-core - and the Inventami board - quad-core. A space benchmark and an avionic benchmark were implemented on both platforms, composed by different modules as showed in Table 1 Each version of the final application was evaluated through fault injection (FI) campaigns, performed using a specifically designed FI system. There were three types of FI campaigns: 1. HW FI, to emulate single event effects; 2. SW FI, to emulate bugs in non-critical applications; 3. artificial bug FI, to emulate a bug in non-critical applications introducing unexpected interference on the critical application. Experimental results show that ODIn is resilient to all considered types of fault

Abstract:
Uppdragsgivaren Saab Electronic Defence Systems i Jönköping erbjuder ett flertal produkter främst inom avioniksystem. För att kunna utvärdera och kontrollera produktens design i ett tidigt skede så kan en simulering av systemets beteende och att felsöka så tidigt som möjligt vara ett möjligt alternativ. En systemsimulering kan innebära att mjukvaruutveckling och felsökning kan påbörjas långt innan hårdvaruprototypen är tillgänglig, med samma storlek och komplexitet som systemet. Andra fördelar med simulering är att det går enklare att fastställa orsaken till systemkrasch, hitta de längsta exekveringstiderna och göra felinjiceringar. Syftet med detta examensarbete är att testa och utvärdera hur simulatorer och emulatorer är som utvecklings- och testverktyg. Rapporten innehåller en marknadsundersökning där tio stycken emulatorer och simulatorer hittades. Av dessa valdes två stycken ut, Wind River Simics och Imperas OVPSim. Tester utfördes för användarvänlighet, debugging, samt jämförande tester mellan riktig hårdvara och simulerad miljö. Resultatet visar att simulatorer kan hjälpa till vid produktutveckling, men att de ännu inte är så optimala för att utvärdera hårdvara i. Detta för att avvikelser kan förekomma i exekveringstider mellan riktig och simulerad hårdvaruarkitektur.<br>This thesis has been carried out in cooperation with Saab Electronic Defence Systems in Jönköping which has a wide range of products, mainly for Avionic applications. In order to evaluate and verify their design it is often required to simulate behaviour and debug as early as possible. System simulation can enable software development and debug to commence long before a hardware prototype is available and also scale with the size and complexity of the system. Another benefit of simulation is to more easily determine root causes to system crashes, establish worst case execution time cases and making fault injection. Therefore this thesis will focus on evaluating simulators and emulators, as development- and testing tools. This report contains a marketing research, where ten emulators and simulators were found. Of these, two simulators were chosen for further investigation; WindRiver Simics and Imperas OVPSim. The evaluations considered both usability and debugging features as well as comparative tests between real hardware and the simulated environment. The results show that simulators can help in product development, but they are not yet optimal for evaluating hardware. This is because deviations may occur in execution times between real and simulated hardware architectures.

Abstract:
International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California<br>Growth in civil aviation is overwhelming worldwide airspace and air traffic services. The International Civil Aviation Organization (ICAO), Federal Aviation Administration (FAA) and Department of Defense (DoD) are proposing or implementing numerous changes to address this growth. The changes are broadly contained in what the civil aviation community calls Communication, Navigation, and Surveillance/Air Traffic Management (CNS/ATM) and the DoD calls Global Air Traffic Management (GATM). A major component of both civil and DoD proposed changes are data link systems digitally transmitting information between aircraft, air traffic control centers, and aircraft operations centers. The real-time interactive nature of these data-link systems and the integration of the aircraft avionics into a worldwide network are forcing aircraft test agencies to acquire access to this capability. Aircraft flighttesting must address both the specific aircraft avionics test requirements and the system-of-systems aspects of data-link applications. This paper describes the factors driving changes in the worldwide CNS/ATM system and identifies specific proposed or implemented changes. Various flight-test requirements, both civil and military, of the proposed changes are enumerated. Particular attention is paid to the DoDs GATM certification requirements. Finally, we present the Air Traffic Control Communications Test Facility and Avionics System Test (ACTFAST) program and explain its capabilities. Rationale for ACTFAST component parts is included along with a brief outline of how the capabilities represented by each component part are used during flight test to acquire the necessary information to meet civil and DoD aircraft certification requirements.

Abstract:
A heat pipe can efficiently transfer heat through it liquid-vapor phase change mechanism. Among different heat pipes, loop heat pipe (LHP) and pulsating heat pipe (PHP) are known to be capable of high heat flux/high load heat transfer. In this article, LHP and PHP heat transfer systems are combined to achieve passive, reliable and long-distance heat transfer for successful thermal management of modern avionic systems. Aiming at this development goal, a 2m long LHP is designed to transport heat from the avionics chassis to the remote heat rejection site. To reduce saturation pressure and ensure structural safety at higher operating temperature, water is used as the operating fluid of LHP. Within the avionic chassis, conduction heat transfer is enhanced by sandwiching and solder-bonding a PHP between two PCBs (printed circuit boards). Each PHP/PCB assembly is 20cm long and 12.5cm wide, with electrical heaters mounted to mimic electronic heat dissipation. Heat transfer demonstration of the LHP and PHP combo system is conducted in a lab environment with input power varying from 100 to 400W. For all three PHP/PCB assemblies set in the avionic chassis, the maximum heat source temperature is less than 130°C, even when input power is twice as much as the state of the art. The enhanced heat transfer consumes less power, increases system reliability, and enables avionic system operation in harsher environments.

Abstract:
&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;Sustainability is both an ethical responsibility and business concern for the aerospace industry. Military and commercial avionics developers have pushed toward a common standard for interfaces, computing platforms, and software in hopes of having “reusability” and reducing weight with backplane computing architectures which, in theory, would support commonality across aircraft systems. The integrated modular avionics (IMA) and military Future Airborne Capability Environment (FACE) standards are two such examples. They emerged to support common computing architectures for reuse and sustainability concepts, from the beginning of aircraft development to the sundown or mortality phase.&lt;/div&gt;&lt;div class="htmlview paragraph"&gt;&lt;b&gt;Pitfalls of Designing, Developing, and Maintaining Modular Avionics Systems in the Name of Sustainability&lt;/b&gt; looks at technological, organizational, and cultural challenges making reuse and IMA platform models difficult to fully realize their sustainability goals. Additionally, it considers the certification aspects of reuse and examines lessons learned from a successful reusable and sustainable platform.&lt;/div&gt;&lt;div class="htmlview paragraph"&gt;&lt;a href="https://www.sae.org/publications/edge-research-reports" target="_blank"&gt;Click here to access the full SAE EDGE&lt;/a&gt;&lt;sup&gt;TM&lt;/sup&gt;&lt;a href="https://www.sae.org/publications/edge-research-reports" target="_blank"&gt; Research Report portfolio.&lt;/a&gt;&lt;/div&gt;&lt;/div&gt;
