<p>The detachable wing spar has upper and lower wing portions (1,2) that are made of prefabricated flexible surface material, and extended to longitudinal direction of wing shape-determining elements such as ribs slats. Pressure-resistant flexural elastic longitudinal struts (5,6) are connected and clamped to respective upper and lower wing spar portions. A planar clamping element (7) is transversely extended from leading edge (3) to diverting edge (4) between top side and underside of longitudinal struts.</p> |
