Abstract

To reduce the gust load of aircraft wings, a new gust load alleviation method using passive ventilation concept with porous surface and deflectable vanes has been proposed. To confirm the effect of this concept, low speed wind tunnel test was conducted on the wing models with gust load alleviation mechanisms. To measure the gust response aerodynamic forces, a gust generator was installed to a low speed wind tunnel in Kyushu University. Three component aerodynamic forces were measured for the steady flow and unsteady gust flow conditions, and it was confirmed that the proposed concept provides the reduction of gust load for aircraft wings with simple mechanism.
