Digital design experiments develop next generation aircraft engine

​Open Rotor is a new type of aircraft engine delivering up to 20 percent reduced fuel burn than today's turbofan engines. Chalmers, together with the University of Cambridge and Fraunhofer FCC, is leading a project that studies aspects of manufacturing during the design phase.

The next generation of aircraft engines is being developed in the large European Joint Undertaking Clean Sky 2. Open Rotor is one of the concepts that has shown promising results when it comes to reducing both CO2 emissions and noise. Open rotor is a new engine type with two, counterrotating, propellers that radically improve propulsive efficiency. This type of technology radically changes how the engines are designed and integrated with the aircraft.

Open Rotor 3 -® Eric Drouin SafranWithin Clean Sky 2, Chalmers, together with Cambridge University and Fraunhofer FCC, is now leading a project called Development of Interdisciplinary Assessment for Manufacturing and Design (DIAS).

DIAS is a targeted support project, where the goal is to develop support for integrating manufacturability aspects already in the design phase, where advanced decision support models are developed. For example, it is critical that robots get to weld the components properly. In the DIAS project, Chalmers latest research results are used in modeling alternative concepts enabling digital experimentation of alternative product architecture, with Fraunhofer's expertise in simulating robotic paths, and Cambridge's expertise in interactive decision-making and modeling-based risk analysis.

–    We have a unique opportunity to combine the latest achievements from Chalmers, Fraunhofer FCC and Cambridge, into a new and powerful way to support GKN Aerospace in their integration of next generation technologies already in the concept phase, says Ola Isaksson, researcher at Chalmers and leader of the consortium.

GKN Aerospace Sweden AB in Trollhättan is responsible for critical engine components of Open Rotor engines. Ultimately, the goal is to enable the methods developed in the DIAS project to enable GKN Aerospace to offer the technologies demonstrated in Clean Sky in future business.
–    We are very happy that this Chalmers led consortium won this Call for Partners. The competition was indeed very tough and this shows that Chalmers is a leading University in this important area in Europe, says Robert Lundberg (Director EU Programmes) at GKN Aerospace Sweden.
