The feasibility of an active and passive gust load alleviation (GLA) approach for flexible wings is assessed in a scaled flight model. The active GLA uses flaps to cancel out eigenmodes. The passive GLA uses a non-linear structural deformation of the wing box forming a flared hinge. The similitude is assessed by static tests and the natural frequencies measured in ground vibration tests.
