Benefiting from Clean Sky SFWA-ITD achievements, the main objective of this call is to contribute to the improvement of gust loads prediction and control in transonic flow conditions. The Applicant(s) will have to design and manufacture model parts composed of an innovative gust generator and a wall-mounted half-wing model to be tested in a selected ONERA transonic facility. In particular, in order to investigate non linearities induced by gust, the novel gust generator will have to produce larger aerodynamic deflections than those obtained from an already existing test mean. Innovative flow control concepts based on unsteady blowing can be considered for achieving the goals in addition to dynamic mechanical devices. Please refer to the full topic descriptions document published in this call.
