The overall objective of this proposal for complementarity is to increase research capabilities in the field of intelligent materials architectures with low weight and high structural performance, advanced manufacturing processes, and experimental investigations for innovative technologies related to ventilator exit (remaster) guidance stators, in order to reduce the noise of the civilian aircraft engines of the future. These expanded capabilities, together with the proposed technical and technological support activities, are intended to provide a basis for the expansion of emerging technologies and innovations related to high dilution motor stators (UHBR) and to increase technological readiness (TRL) in order to obtain validation of a full-scale demonstrator on an experimental stand in an environment appropriate to real-engine operation. The objectives of the complementarity project are directly linked to this target, aiming at validating the application of the technologies and concepts of escape stator guides proposed in the InnoSTAT project. First, the demonstrators that materialise the 5 concepts of exhaust guides developed, manufactured and tested will continue to be evaluated from a thermomechanical point of view: 3 exhaust guide blades demonstrators of a full three-dimensional 1/3 scale stator step (TRL4), and 2 concepts of selected exhaust guide blades developed, manufactured and tested at full scale (TRL3) in an aero-acoustic stand for large-scale fans (under the CSJU project) in order to verify how they correspond to the conditions of a real engine, thus advancing the technological maturity level from 3 (in the CSJU project) for full-scale exhaust guide blade demonstrators to 4 at the end of this complementarity project. Secondly, a concept of escape stator plates will be developed, in addition to the concepts proposed in the InnoSTAT CSJU project. The project uses a very ambitious systematic procedure to “design/understand/prove/demonstration” the two additional concepts, a procedure not implemented so far, of what we know. The concept will be based on a new approach to noise reduction, using elastic attack edges and elastic ribs on the intradoss and extrados. As a result of these technical and technological development activities, the depth of knowledge gained in the field is expected to increase, providing the basis for future related research topics, a significant increase in the impact of the CSJU InnoSTAT project and ultimately leading to a significantly increased contribution to the noise reduction of civil aviation engines. In order to facilitate the achievement of the above-mentioned objectives of the project it is necessary to develop
