Tragflügelkonstruktion für ein Wasserfahrzeug, dessen nach vorne gerichtete dynamische Bewegung relativ zum Wasser ausgenutzt wird, gekennzeichnet durch ein Paar von am Wasserfahrzeug angebrachten, in Querrichtung voneinander getrennten Trägern (15), an deren Enden ein Tragflügelprofil (17a; 17b) hydrodynamischen Querschnittes befestigt ist, dessen Spannweite zwischen den Trägern größer als der seitliche Abstand der Träger voneinander ist, wobei das Tragflügelprofil hinsichtlich seiner Form in Fahrt solche Form besitzt, daß die auf das Tragflügelprofil längs der Spannweite ausgeübten Hubkräfte Beanspruchungen kolinear-zur hydrodynamischen Mittellinie des Tragflügels entwickeln.1.) Hydrofoil construction for a watercraft, its forward dynamic movement relative to the water is exploited, characterized by a pair of attached to the watercraft, separated from each other in the transverse direction Supports (15), at the ends of which an airfoil profile (17a; 17b) of hydrodynamic cross-section is attached, the span of which between the beams is greater than the lateral distance between the beams, the airfoil with respect to its shape in motion has such a shape that the exerted on the airfoil along the span Lifting forces collinear to hydrodynamic stresses Develop the centerline of the wing. 2.) Tragflügelkonstruktion nach Anspruch 1, dadurch gekennzeichnet, daß der Tragflügel (12) in fester einheitlicher Konstruktion ausgebildet ist.2.) hydrofoil construction according to claim 1, characterized in that that the wing (12) is formed in a solid unitary construction. 3.) Tragflügelkonstruktion nach Anspruch 1, dadurch gekennzeichnet, daß der Tragflügel aus einer Vielzahl gelenkig aneinander gelagerter hydrodynamisch ausgebildeter Abschnitte (4-2) zusammengesetzt ist.3.) hydrofoil construction according to claim 1, characterized in that that the wing consists of a large number of articulated hydrodynamically designed sections (4-2) is composed. 4.)
