The Applicant shall characterize in wind tunnel the key design choices of the basic engine intake configuration, as defined by LH. The Applicant will also propose optimized geometries (by CFD) to be evaluated in the same testing campaign. Moreover, it will characterize (by CFD only) the interactional effects due to rotor wake and its impact on the intake performance. Then, due to the peculiarity of the proposed intakes, an analytical assessment on the ice and snow effects shall be addressed. The novel intake geometry features will be installed on the Technology Demonstrator. Please refer to the full topic descriptions document published in this call.
