ISVR Research seminar

Travelling by aircraft has advanced to a frequently chosen mode of transport, where safety, comfort and relatively inexpensive ticket prices are appreciated by a growing number of passengers. The related increase of flights, however, becomes more and more problematic to associated emissions contributing to the observed beginning climate change. In consequence, there is a strong need for future air travel to significantly reduce pollution with CO 2 , which inescapably will task air framers to further increase the aerodynamic performance of aircraft, to reduce structural weight and of course to extend the efficiency of aircraft propulsion. First steps already have been realised through engines of an enlarged by-pass ratio and discussions of a rebirth of propeller engines for larger aircraft types have emerged on internal air framer´s meetings.

Apart from other difficulties coming along with the new propulsion systems, cabin acoustics obviously will be dominated from tonal sound waves especially of low frequencies penetrating easily aircraft cabin walls of today’s technology. In order to maintain passenger´s comfort experiences a huge challenge on the design of future aircraft cabins has to be completed facing numerous and strong requirements such as weight, occupied space and costs for fabrication, installation and maintenance. Additional functionalities of cabin components supporting profits of course are welcome and support the introduction of new technologies.

In this seminar, recent research results on a new cabin wall design taking into account the described field of requirements will be presented. The presentation will start with an introduction to state-of- the-art of technology with a focus on aircraft cabin acoustics and related influences followed by a description of the awaited challenges on acoustic cabin comfort. Then, a new cabin wall design concept and its recent research results will be presented, describing different passive acoustic treatments, such as metamaterials, resonators, micro-perforated absorbers and new materials to be used in a special arrangement. With some results of another design objective for a significantly reduced moisture condensation inside the cabin wall allowing higher humidity levels inside the cabin the talk will be concluded.
