Abstract [en]

In aircraft development, it is crucial to understand and evaluate behavior, performance, safety and other aspects of the subsystems before and after they are physically available for test. Simulation models are used to gain knowledge in order to make decisions in all development stages. This paper focuses on a special kind of simulation technique called Hosted Simulation, when a model created in one tool is generated to executable code and imported (hosted) in another tool to perform simulation.

In this paper we report on experience gained from evaluating two different approaches of hosted simulation. Furthermore, the suitability of the two approaches can vary during different phases of aircraft development and utilization, from concept evaluation to end user support. The model of an aircraft subsystem shows that hosted simulation is a powerful and efficient technique.

Abstract [en]

Aircraft developers like other development and manufacturing companies, are experiencing increasing complexity in their products and growing competition in the global market. One way to confront the challenges is to make the development process more efficient and to shorten time to market for new products/variants by using design and development methods based on models. Model Based Systems Engineering (MBSE) is introduced to, in a structured way, support engineers with aids and rules in order to engineer systems in a new way.

In this thesis, model based strategies for aircraft and avionics development are studied. A background to avionics architectures and in particular Integrated Modular Avionics is described. The integrating discipline Systems Engineering, MBSE and applicable standards are also described. A survey on available and emerging modeling techniques and tools, such as Hosted Simulation, is presented and Modeling Domains are defined in order to analyze the engineering environment with all its vital parts to support an MBSE approach.

Time and money may be saved by using modeling techniques that enable understanding of the engineering problem, state-of-the-art analysis and team communication, with preserved or increased quality and sense of control. Dynamic simulation is an activity increasingly used in aerospace, for several reasons; to prove the product concept, to validate stated requirements, and to verify the final implementation. Simulation is also used for end-user training, with specialized training simulators, but with the same underlying models. As models grow in complexity, and the set of simulation platforms is expanded, new needs for specification, model building and configuration support arise, which requires a modeling framework to be efficient.

Abstract [en]

In aircraft development, it is crucial to understand and evaluate behavior, performance, safety and other aspects of the systems before and after they are physically available for testing. Simulation models are used to gain knowledge in order to make decisions at all development stages.

Modeling and simulation (M&S) in aircraft system development, for example of fuel, hydraulic and electrical power systems, is today an important part of the design process. Through M&S a problem in a function or system is found early on in the process.

An increasing part of the end system verification relies on results from simulation models rather than expensive testing in flight tests. Consequently, the need for integrated models of complex systems, and their validation, is increasing. Not only one model is needed, but several interacting models with known accuracies and validity ranges are required. The development of computer performance and modeling and simulation tools has enabled large-scale simulation.

This thesis includes four papers related to these topics. The first paper describes a modeling technique, hosted simulation, how to simulate a complete system with models from different tools, e.g. control software from one tool and the equipment model from another. The second paper describes the use of M&S in the development of an aircraft. The third and fourth papers describe how to increase knowledge of the model’s validity by sensitivity analysis and the uncertainty sources.

In papers one and three an unmanned aerial vehicle is used as an example and in paper four a pressure regulator is the application.
