Military Technology

A fixed compliant wing system is provided that is coupled to a rigid spar and a rigid stopper. The fixed compliant wing system includes an actuator and at least two compliant rib structures coupled to the rigid spar. The compliant rib structures include an outer compliant contoured structure, a drive member coupled to the outer compliant contoured structure and including a guiding slot consisting of at least two interconnected portions. The guiding slot encompasses and is in a sliding arrangement with the rigid stopper. The drive member is further connected to the actuator. Portions of the outer compliant contoured structures are configured to independently deform when force is applied from the actuator to the drive member thereby moving the rigid stopper from a first portion to a second portion of the guiding slot. The fixed complaint wing system further includes a skin encompassing the compliant rib structures.
