Defaine Dissemination At The European Aeronautics Science Network (EASN) International Conference

Updated: Jan 17

Representatives from Chalmers University of Technology travelled to Salerno (Italy) the 5-8 September 2023 to present at the European Aeronautics Science Network (EASN) International Conference. Two sessions were held:

Club Design



The presentation focused on a web-based tool (Club Design) to enable automated cost-benefit analysis of design and business alternatives within the aerospace propulsion business.


Club Design is the result of a decade of research within the aeronautical and space sector and it enables a ‘batch run’ cost-benefit analysis of several aerospace design concepts (e.g., different concepts for the propulsion system) onto different business scenarios (e.g., long-haul flights, small regional aircraft, and shortage of fuel/electricity).


 Cost and Revenue profiles (Surplus Value, SV, in k€) for 20 design concepts for a Fan Outlet Guide Vane (FOGV) on a ultra-short regional flight business. The best  design is the one that either gives the highest SV or that gives the shorted payback. 


The presentation focused on the value of promoting a cost-benefit analysis of large design spaces, already from the early phases of product design (and from system design down to sub-systems and components).


Such tools are becoming more important since the aerospace industry is pushing to consider new and disruptive concepts, both in the technology (e.g., electric, hydrogen and hybrid) as well as in the business domain (e.g., small regional transportation). However, the cost-benefit comparison between these radical concepts is difficult today, since the alternatives present different parameters, scales and modelling logics.

Production considerations in the conceptual design of aircraft structures

TU Delft/ GKN Fokker

The second presentation by TU Delft and GKN Fokker Aerostructures was discussed the development of a model based approach for automatically inclusion of  manufacturing and assembly considerations into the conceptual design of aircraft structures. The proposed methodology is based on a Manufacturing Information Model (MIM), that integrates with existing KBE applications and allows related analysis.

Overview of the Manufacturing Information Model (MIM)

The MIM consists of three modules, namely the manufacturing model, the database and the assembly model. Together they enable capturing information about how a product (and

its constituent parts) can be manufactured and assembled. The MIM allows the formalization of information that is usually stored in static documents or only known by engineers through experience. The proposed model-based approach allows a much more effective and systematic reuse of such knowledge, for example, to perform automatic checks for compatibility between production and design decisions to ensure feasible designs.

The MIM allows for identification of trends, and to rank different manufacturing concepts accounting for the  requirements imposed on both product and production methods, thereby supporting the decision making process. .


The results are a joint effort between DEFAINE and AGILE 4.0
