Extended Abstract

It is common consensus that developments of complex engineering systems have to be carried out in accordance with a well-established set of taxonomies, rationales, processes, rules, and techniques formally defined and embodied within a systems engineering methodology. Model-Based System Engineering (MBSE) essentially applies a coherent set of models supporting all system analysis, design, validation and verification activities throughout the whole lifecycle of a system of interest. It is believed that MBSE approaches have the potential to vastly improve the systems engineering of modern, complex systems characterized by the integration of hardware, software, and human interaction.

Therefore, MBSE approaches rapidly gain wide acceptance and is growingly applied in many industrial sectors including developments of complex engineering systems. Particularly, MBSE approaches are widely used to support developments of complex electromechanical products, which apparently embody the typical multidisciplinary characteristics of complex systems. For instance, the German Aerospace Center (DLR) applied MBSE approaches in developing a virtual satellite of a multi-mission platform, which will meet diverse customer requirements.

This presentation addresses the application of MBSE approaches to engineering developments of aeroengine turbine blades. Developing a turbine blade requires analyses, simulations and validations of multidisciplinary phenomena including exhaust flows, coolant flows, heat transfer, structural deformation and vibration, material strength and failures. The ultimate goal of developing a turbine blade is to determine the blade’s external shape as well as the internal cooling geometries that attain desirable aerodynamic, thermodynamic, and structure dynamic performance measures. At the same time, the blade design is expected to increase the operational reliability and durability, which usually contradict the performance measures. Technically, developing a turbine blade is a problem of a system of systems (SoS), which has been a center stage of the Systems Engineering.

Subsequently, MBSE approaches in conjunction with the SysML tools are introduced to blade engineering processes. It is believed that applications of MBSE approaches provides multidisciplinary engineering teams with panoramic views of the blade engineering processes as well as implementation details of disciplinary models. It is anticipated that the MBSE approaches will bring into forth a number of benefits, such as enhanced teamwork, increased engineering efficiency and accuracy, and decreased model conflicts and costs.
