Important results from the project
The goal of the project was to create a strong Swedish role by demonstrating 9 complex engine components together with OEMs in international cooperation. This objective has been met. The project has also positioned GKN and participating SMEs for future product development and series manufacturing projects with OEMs within GKN´s specialization in complex engine structures. The project met the goal of taking a role in the Clean Aviation project
Expected long term effects
The 9 component demonstrators validated new technology for lower weight (15-30%), higher temperature (150-200°C) and increased functionality. During 2023, GKN became partner in two demonstrators in Clean Aviation. Also Chalmers participates in one of these. SMF partners as well as the 17 SME subcontractors have taken great steps towards becoming certified series suppliers to GKN and other aircraft engine companies. Permanova was acquired by GKN during the project period. Today they form the core of a new division within GKN that invests heavily in additive manufacturing.
Approach and implementation
The project was integrated in GKN´s project management organization for technology development of demonstrators. GKN´s proven methods for demonstrator development and TRL maturation, with clear and well-documented design and TRL reviews, have been used. The project was divided in the following work packages: 1. Fan structure 2. Compressor Structure 3. Turbine Structure 4. Repair Technologies During the pandemic, the project was behind schedule, but caught up later. After an extension of 3 months, we also had time to evaluate data from engine tests and rig tests at OEM.
