Modular tool development towards complex geometries in aeronautical designs

Reference number
Coordinator Swerea SICOMP AB - Swerea SICOMP AB, Linköping
Funding from Vinnova SEK 325 000
Project duration June 2017 - May 2018
Status Completed

Purpose and goal

The aim of the current project was to develop specialized modular tools in composite materials that can produce complex, high performance articles. A new complex design for the A-beams of the aircraft were produced. The design was evaluated under FEM, adjusted, a tool was manufactured and the produced composite demonstrator was evaluated for geometrical distortions. Nordic Aircraft personnel inspected the article and it was approved to be used for the actual aircraft.

Expected results and effects

Within this project, a new design was produced. The challenge was to include: complexity, modularity in the part production and integrate structural details, such as hard point attachments. The initial design was produced and put to test under FEM calculations. A respective Abaqus model was produced, the thermal strains were estimated and the design was accordingly compensated. Finally the composite composite article was manufactured, compared to the design and approved to use into the company´s aircraft.

Planned approach and implementation

This project produced the following value for Nordic Aircraft. -A new, novel design for a tool which supports ease of manufacturing -A numerical model on Abaqus (FEM commercial software) for this design which can be used for curing and thermomechanical simulations -A composite demonstrator with confirmed geometrical accuracy which will be directly used for the production of the aircraft.
