Special Issue Information

Dear Colleagues,

text

Aerospace electronics is continuously evolving in the variety of mission applications and through the ever-increasing demands of complex systems that must meet the environmental challenges presented by space and aircraft operations. Electronic and photonic components serve to collect data, provide controls and communications, and afford power regulation in integrated systems, and they must survive launch vibration, thermal environments, and radiation exposure. Traditional components used for aerospace are giving way to commercial off-the-shelf solutions that can provide greater performance at lower costs. At the same time, the design processes are evolving into more agile and cost-effective approaches while antiquated standards based upon military handbook methods are no longer adequate for design analysis.

The emergence of Model-Based Systems Engineering (MBSE) to govern the synthesis of the architecture is rapidly evolving, and MBSE-driven reliability analysis is following quickly along with it, providing for new high-value approaches to system reliability analysis. Physics of failure is now recognized as an important technique in reliability analysis at the board and component level. An obvious nexus is emerging to create a complete solution to reliability analysis. Many new developments are needed which will incorporate all sources of data into the analytical process to rapidly assure that systems will meet the demands.

This Special Issue of the online journal Aerospace is seeking a wider range of papers covering the latest developments in the reliability analysis of aerospace electronics. Of special interest are the latest developments driven by MBSE at the system level. In addition, articles covering the latest developments and applications of the physics of failure—inclusive of radiation effects—are sought for this journal. This includes the analysis of failure mechanisms and the incorporation of probabilistic methods concurrently with physics of failure, as well as effective uses of test data and field operational data within the analytical framework.

The cost of avionics maintenance is extremely high for modern aircraft. It can be as high as 30% of the aircraft maintenance cost. A great impact on the cost of avionics maintenance is provided by a high level of No Fault Found events (NFF). Intermittent faults are the leading cause of the NFF appearance in avionics. The NFF rate for avionics systems is between 20% and 50%. The practice of avionics operation and maintenance confirms the relevance of assessing the impact of intermittent faults on the maintenance cost and the choice of such option of the maintenance management, in which the negative impact of the intermittent faults is minimized. In this paper, a new mathematical model of digital avionics maintenance is developed. Key maintenance effectiveness indicators are selected. General mathematical expressions are obtained for the average availability, mean time between unscheduled removals (MTBUR), and expected maintenance cost of single unit and redundant avionics systems, which are subject to permanent failures and intermittent faults. The dependence of the maintenance effectiveness indicators on the rate of permanent failures and intermittent faults is investigated for the case of exponential distribution of time to failures and faults. The dependence of average availability on the number of spare units in the airline’s warehouse is also analyzed. On the base of the proposed maintenance model, different options of avionics maintenance management are considered. Numerical examples illustrate how to reduce the expected maintenance cost of avionics systems. Full article

The development of time-critical Distributed Avionics Applications (DAAs) pushes beyond the limit of existing modeling methodologies to design dependable systems. Aerospace and industrial automation entail high-integrity applications where execution time is essential for dependability. This tempts us to use modeling technologies from one domain in another. The challenge is to demonstrate that they can be effectively used across domains whilst assuring temporally dependable applications. This paper shows that an IEC61499-modeled DAA can satisfy temporal dependability requirements as to end-to-end flow latency when it is properly scheduled and realized in a fully deterministic avionics platform that entails Integrated Modular Avionics (IMA) computation along with Time-Triggered Protocol (TTP) communication. Outcomes from the execution design of an IEC61499-based DAA model for an IMA-TTP platform are used to check runtime correctness through DAA control stability. IEC 61499 is a modeling standard for industrial automation, and it is meant to facilitate distribution and reconfiguration of applications. The DAA case study is a Distributed Fluid Control System (DFCS) for the Airbus-A380 fuel system. Latency analysis results from timing metrics as well as closed-loop control simulation results are presented. Experimental outcomes suggest that an IEC61499-based DFCS model can achieve desired runtime latency for temporal dependability when executed in an IMA-TTP platform. Concluding remarks and future research direction are also discussed. Full article
