An innovative air distribution system based on innovative materials with e.g. better acoustical damping, higher level of functional integration, etc. shall be developed using a model based design approach. This development shall be integrated in a Cabin Demonstrator and allow for mock-up ventilation with fresh and recirculated air. Furthermore, the developed system shall be flexible to integrate various subcomponents of the ECS, thereby realistically emulating the function of the whole ECS system. Please refer to the full topic descriptions document published in this call.
