Abstract [en]

This paper presents and analyses the research front on development methodologies that can be applied to flight simulations for development purposes. This field includes any flight simulator used during the development phase of an aircraft, when flight test or other validation data is still scarce. A review of the literature published between 1999-2019 is performed. As flight-specific literature on the topic is limited, a broader view on flight simulators is adopted. Simulators are regarded as risk-averse scientific software; that is, software created to understand a phenomenon and whose primary goal is to be correct. This perspective highlights the lack of suitable established software development methodologies (SwDev) for this software type. Two solutions to this problem have been identified: one treating scientific SwDev as a knowledge acquisition process, and another one treating it as development of enabling systems, following the established product development processes. These solutions need to be completed with methodologies to deal with the multidisciplinarity of the flight simulation problem, such as model exchange standards or workflows for multidisciplinary collaboration.

Abstract [en]

The aerospace industry has a long tradition of using Model Based Systems Engineering in its development processes. Throughout the years an extensive library of system simulation models has been created, expanding with every new model being developed. Nevertheless, modelling and simulation engineers prefer developing their own models from scratch, as the reuse of legacy models seems cumbersome, leading to the simultaneous existence of multiple simulation models of the same system in a project. Not only does the development, verification and validation and maintenance of these multiple simulation models incur extra costs, but they also represent a potential threat to the aircraft development, as data consistency is more difficult to be ensured. 

The aim of this thesis is to investigate simulation model reuse during the aircraft development process, with the goal of creating an easy-to-reconfigure simulation framework, allowing for the inclusion of simulation models of various levels of fidelity. Through an industry-as-laboratory approach, the inclusion of industry-grade legacy system simulation models is investigated, with the help of simulation model integration standards such as Functional Mock-up Interface and System Structure and Parametrisation. 

The results of the work include the development of a proof-of-concept simulation framework that enables the aggregation, integration and reuse of simulation models from different technological domains and with different levels of fidelity. Moreover, the work proposes a workflow that streamlines the decision milestones when faced with the possibility of selecting between creating a new system simulation model or reusing a legacy one, and highlights the challenges associated with model reuse from both a technical and an organisational perspective.
