GKN to develop nested fan technology for electric aircraft


GKN Aerospace has started a project to develop fan technology for electric aircraft in Sweden.

The 18-month EleFanT project, which started in July, is being carried out with KTH (the Royal Swedish Institute of Technology) and will develop a nested fan suitable for use in regional aircraft.

The project is supported by the Swedish Energy Agency and will be carried out at GKN’s Global Technology Center in Trollhättan, Sweden.

The project will study the aerodynamic design, performance, noise and manufacturing technology of a nested fan powered by electricity, either from batteries, hydrogen fuel cells or even more conventional hybrid propulsion solutions.

According to GKN, the proposed propulsion solution offers advantages in terms of safety, noise level and engine installation. The EleFanT project aims to “accelerate the pace of electric aviation development and position participants for international aircraft and aircraft engine development projects,” he said.

“We are very positive about this initiative, which helps us be part of the solution to the aviation climate challenge. We will greatly benefit from GKN Aerospace and KTH’s long experience in turbomachinery, lightweight construction and advanced manufacturing technology. From an electrification and sustainability perspective, the project is strongly aligned with our recently announced H2GEAR and H2JET programs. said Henrik Runnemalm, vice president of GKN Aerospace Global Technology Center in Trollhättan, Sweden.
