Actuation for More Efficient Aircraft

Important results from the project

The project has through a model-based approach studied and compared different actuator technologies for maneuvering of aircraft. Both hydraulic and electric actuators have been included. The focus was to study characteristics such as power consumption, effects from temperature, weight and size. An initial work of creating a large-scale research platform took place. The platform, an Iron Bird, will support future projects. Initial tests of an electric actuator ware done. Several articles and Master theses were published as well as a licentiate thesis.

Expected long term effects

The project results and the gained knowledge are a clear support to Saab’s studies on the future combat aircraft system. Hydraulic and electric actuators have very different characteristics suitable for different applications. It is important to select the right technology roads early since the actuation system has a large impact on the overall aircraft. The project results contribute with both knowledge and models that can be used in continued studies. LiU’s academic position has been strengthen through the creation of a new research group.

Approach and implementation

The project combined theoretical and experimental activities. Collaboration with other projects enables the creation of a larger research group. This has resulted in positive effects through an exchange of knowledge and collaboration around similar research questions. An interaction with industry and knowledge dissemination took place through regular meetings and seminars, as well as participation at international conferences. A senior researcher with dual positions further strengthened the industry-academic collaboration.
