The GKN Aerospace-led G5Demo project, part of the Swedish Green Aerospace Demonstrator programme, is to receive Euros 2million in funding from Vinnova (Swedish Governmental agency for innovative systems). This funding will be matched by an equivalent investment from GKN Aerospace and will be provided over a two year period to support an increase in the scope of the G5Demo activity.

The Green Aerospace Demonstrator programme encourages the participation of Swedish industry and research establishments in international demonstrator programmes such as Clean Sky and Sesar which are validating new technologies through demonstrator trials. A particular goal is to increase the participation in these programmes of small and medium-sized companies and organisations.

G5Demo is an engine demonstrator programme focused on progressing technologies that will reduce aero-engine CO2-emissions by 50% by 2020, with the funding from Vinnova extending and encouraging Swedish industrial participation. As part of the programme, two Sweden-based centres for aerospace manufacturing technology are being supported: the manufacturing technology centre at Innovatum, Trollhättan which focuses on metal technologies; and COMPRASER, based in Linköping, which focuses on composite technologies.

GKN Aerospace’s contribution will be to introduce innovative manufacturing technologies and advanced materials to G5Demo, allowing the creation of light weight, state of the art engine structures which can then be validated in the full-sized aero-engines that form the project demonstrators. Through this project GKN Aerospace will be supporting Swedish universities, research centres and small /medium sized enterprises (SMEs), introducing them to international collaboration and working with them to progress and assess a variety of new technologies and processes.

Engine parts that are being developed through G5Demo include:

  • A turbine structure that is 15 % lighter and survives 200°C higher temperatures
  • A composite/metal hybrid fan frame that is 30 % lighter
  • Rotating frames for ‘open rotor’ engines
  • Compressor structures manufactured using 3D-printing

Technologies and materials that are being progressed include:

  • Novel welding technologies
  • Non-destructive testing (NDT)
  • Automated composite manufacturing
  • Innovative sheet metal forming
  • High temperature alloys
  • Acoustic panels for use at high temperature
