- As functional (total care) products emerge in the jet engine industry, the need for product life-cycle models capable of definition and evaluation of life cycle properties increases, since functional products (FP) includes both hardware and service. Recent life-cycle models are intended for hardware products and mostly handle design and manufacturing knowledge. The aim of this article is to present a design approach that extends the evaluation capabilities beyond classical hardware design and manufacturing evaluation. The focus has been to introduce evaluation of manufacturing and post-manufacturing activities in evaluation of conceptual designs. For this purpose, a model has been proposed to handle the information flow between teams when developing structural jet engine components. A case study, in which the proposed model was used in cooperation with a jet engine component manufacturer, is presented. Aspects concerning design, manufacturing, performance, and maintenance of jet engine flanges were included in the example by means of a knowledge based engineering (KBE)-system coupled to databases and spreadsheets. The model is more suitable than recent work for the development of hardware parts of functional products (HFP), since knowledge from more product development disciplines is included. As the engineer changes the design and directly assesses the life-cycle cost (LCC) and how the changes impact the interface to other jet engine components, more knowledge on the impact of design decisions is available at hand for the engineering designer than without the model

- Aviation strives today to include environmental and social considerations as drivers for decision making in design. This paper proposes a serious game to raise awareness of the value and cost implications of being ‘sustainability compliant’ when developing aerospace sub-systems and components. After describing the development of the game, from needfinding to prototyping and testing, the paper discusses the results from verification activities with practitioners, revealing the ability of the game to raise sustainability awareness and support negotiation across disciplinary boundaries in design

- Novel rotating machinery design concepts and architectures are being explored to reduce mass, energy consumption, manufacturing costs, and environmental impact while increasing performance. As component manufacturers supply parts to original equipment manufacturers, it is desirable to design the components using a systems approach so that they are optimized for system-level performance. To accomplish that, suppliers must be able to model and predict the behavior of the whole machinery. Traditional computer-aided design/computer-aided engineering master-modeling approaches enable manual changes to be propagated to linked models. Novel knowledge-based master-modeling approaches enable automated coordination of multidisciplinary analyses. In this article, we present a specific implementation of such a knowledge-based master-modeling approach that facilitates multidisciplinary design optimization of rotating machinery. The master-model (MM) approach promotes the existence of a single governing version of the product definition as well as operating scenarios. Rules, scripts, and macros link the MM to domain-specific models. A simple yet illustrative industry application is presented, where rotor-dynamics and displacement analyses are performed to evaluate relocation alternatives for the rear bearing position of a rotating machinery under a ‘fan-blade-off’ load case.

Numerical evaluation of rotordynamic coefficients for compliant foil gas seal
- 2020
-
Ingår i: Applied Sciences. - : MDPI AG. - 2076-3417. ; 10:11

Tidskriftsartikel (refereegranskat)abstract
- Compliant foil gas seal is one of the advanced cylindrical gas seal technologies and can be commonly used in the secondary flow system of an aero-engine. It can enhance the dynamic stability of the aero-engine by meeting the steady requirements of the aero-engine seal system. To evaluate the performance of compliant foil gas seal, the steady performance of the gas seal is firstly analyzed to predict the sealing efficiency and obtain the pressure distribution of the gas seal in the compressible flow field. Then, the effects of the operating parameters on the rotordynamic coefficients are analyzed using the finite differential method. It can be used to predict the operation performance of the aero-engine and prepare for the optimization and test rig of compliant foil gas seal on the T-shaped groove. © 2020 by the authors.

- A radical shift in technology is necessary to enable future air transport solutions. Sustainability targets for aeroengine manufacturing mean more than reducing CO2 and NOX. The future will open up possibilities and bring new challenges when introducing hybrid- and electrical propulsion technologies using new materials, technology solutions and new business models. This article reports on findings from a longitudinal study and many years of collaboration between researchers and industry experts, where a first-tier aeroengine manufacturer transforms their product development capabilities to enable sustainable product development. The article highlights some activities undertaken and identifies critical challenges and opportunities remaining for a manufacturer of next-generation aeroengine solutions. It is argued that the challenge for aeroengine manufacturers to develop new-generation propulsive technologies will require a systemic change in the undertaking of design and development. The opportunities of sustainable technologies are evident yet require: (1) means to tighter integrate business and technology development, (2) the ability to quantify and assess sustainability impacts of different concept solutions, and (3) means to utilise natural resources, alloys and materials for a circular and life-cycle optimised solution.

Konferensbidrag (refereegranskat)abstract
- Emerging from an industrial case study in the aerospace industry, the paper proposes an approach to evaluate sub- system technology concepts from a life cycle perspective. The approach is composed by 5 main phases that aims to drive product designers towards more value-oriented design decisions. It is shown how different life cycle alternatives, such as the selling of a Product-Service-System instead of a traditional product, deeply impact the value of design alternatives. The described approach has been developed in collaboration with industrial partners and represents a potential instrument to enhance value-driven product design.

- Designing and implementing a Knowledge Management System (KMS) in a Virtual Enterprise is a labour intensive and risky task. Solution prototypes (Pilots) are usually built to verify system effectiveness prior to final implementation. The paper proposes a methodology to guide this Pilot specifications definition process. These guidelines support engineers and knowledge experts in collaboratively defining functionalities, services, software components and performance indicators of the prototype. The methodology has been conceived and applied within the European project VIVACE, to support the development of a Knowledge Enabled Engineering (KEE) system in the aeronautical domain.

- Industry is a main stakeholder when it comes to realising the transition towards a sustainable future. Academia, with its, knowledge and methods, needs to support the industry on this journey. This paper, focuses on the practical learnings on how to implement sustainability research from an industrial perspective. It aims to share some lessons learnt from a longitudinal case study and a development journey in implementing sustainability research in the product innovation process at GKN Aerospace Engine System. The paper gives an overview, based on a literature study, of what is required to successfully implement sustainability in product development. It also provides a summary of the different research projects at the company with learnings from practical and academic perspectives, and the main learnings and changes in relation to different development phases in the sustainability journey. Although, this journey began over ten years ago, and shows the importance of long-term collaboration, it provides key-factors that can be applied also in short term collaborations and for faster implementation of research in general and sustainable product development research in particular.

DERIVE AND INTEGRATE SUSTAINABILITY CRITERIA IN DESIGN SPACE EXPLORATION OF ADDITIVE MANUFACTURED COMPONENTS
- 2023
-
Ingår i: Proceedings of the Design Society. - : Cambridge University Press. ; 3, s. 1197-1206

Konferensbidrag (refereegranskat)abstract
- Additive manufacturing has the potential to decrease the climate impact of aviation by providing more light-weight designs. Sustainability is however required to be assessed from a systemic view, including all lifecycle phases, and from a social, ecologic, and economic dimension. This is however challenging in early phase design, where also a large design space need to be explored. A case study is carried out with an aerospace company where two candidate engineering design tools are combined to address this. The integration of these two engineering tools are applied on a Turbine Rear Structure, and shows promising results in enabling a systemic view of sustainability to be integrated and assessed in early phase design space explorations of additive manufactured components. It is recommended that the integration between the two tools is further established and validated. © The Author(s), 2023. Published by Cambridge University Press.
