As part of its commitment to the decarbonization of the aviation sector and the UN Race to Zero global campaign, Rolls-Royce is actively developing hydrogen combustion gas turbine engine technology capable of powering a range of aircraft from 2035 onwards. These innovative technologies are undergoing integration and validation through a demonstrator project, which involves the modification of a Pearl15 engine for ground testing with gaseous and liquid hydrogen. The design of an aerospace combustor needs to satisfy conventional requirements such as cost, weight, aero-thermal performance, and lifespan. However, the introduction of hydrogen as the primary fuel introduces additional challenges, including potential novel failure modes, operability considerations and pollutant emissions. The NOx emissions resulting from hydrogen combustion are currently the subject of extensive research and are considered, to be one of the key considerations which will ultimately influence the design of the optimum hydrogen combustion sub-system for aerospace applications. This paper describes the development of the first prototype combustion technology at Rolls-Royce. Innovative fuel injection concepts were investigated to enable operation with 100% hydrogen on the Pearl 15 combustor architecture which is to serve as the test vehicle for ground demonstration in the Clean Aviation Project "CAVENDISH". The paper details the process which began with prototype development and validation on a single sector atmospheric test rig to map the design space and understand sensitivities. This allowed the selection of four leading configurations based on NOx emissions, flame stability (measured using optical methods), ignition and weak extinction performance. The four configurations were then tested in a single sector, intermediate pressure rig testing at engine-representative low power conditions. This testing aimed at identifying challenges related to flame stability and combustor temperature distri

The cost-effectiveness and efficiency of any manufacturing system are now more critical than ever. Therefore the embracing of Industry 4.0 is underway. Interconnectedness and smart automation with the integration of the Manufacturing Execution System (MES) are the key concepts of Industry 4.0. The fast-paced industrialization 4.0 requires a good insight into existing concepts and methods. There are many ideas and concepts that are integrated into the advancement of Industry 4.0. This paper explores the integration of preventive maintenance concepts and methods used by the fourth industrial revolution, ideas like the Industrial Internet of Things (IIoT), Cloud Manufacturing (CM), Machine Learning (ML), Product Lifecycle Management (PLM), Digital Manufacturing (DM), and Digital Twins (DT). This paper will introduce additional concepts into the conference paper, Intelligent process Control Following Industry 4.0 Trends, with Siemens PLM product, Tecnomatix.

Knowledge concerning the integrationprocessthroughout a system life cycle is critical for introducing new technologies. Advances in digital technologies and high-fidelity digital models may lessen investments in physical models to fulfill programmatic requirements when verifying space systems. Digital engineering, model-based systems engineering, and digital twins literature link to this topic. The integration Readiness Levels (IRL) scale is an emerging good practice that complements the Technology Readiness Levels (TRL) scale in supporting the integration of technologies into a system. IRL has been evolving over the past fifteen years. However, IRL still provides few specific directions on the use of modeling and simulation to achieve its levels. The research objective is to propose a method that suggests whether and under what conditions modeling and simulation could comply with integration Readiness Levels for space systems. Results show the proposed theory and how it was developed through the design science research method. The proposed method addressed model-based capabilities, system lifecycle processes, and information items in a set of suggested criteria for each IRL and additional considerations. This paper could support practitioners in making decisions about using modeling and simulation to meet integration Readiness Levels and could support organizations in planning their model-based capabilities.
