Apparatus for transmission and recovery of aerodynamic profile element, and aerodynamic profile element

Abstract

The invention relates to an aerodynamic profiled element for generating power by means of a tractive force, especially for driving watercraft. Said profiled element comprises a flexible top layer that extends in a transversal direction and a longitudinal direction, a flexible bottom layer which extends parallel to the top layer and is connected to the top layer by means of several webs that run in a downward direction of the profiled element, an air-filled interior space between the top and the bottom layer, at least one ventilation hole for ventilating the interior space, said at least one ventilation hole being disposed between two parallel forward edges of the top and bottom layer, several traction lines, a first end of which is fastened to the profiled element at spaced-apart points and a second end of which is connected to a traction rope for connecting the profiled element to a watercraft, and several reefing lines, a first end of which is attached to the layers and / or webs. Said reefing lines are embodied so as to reduce or increase the size of the profiled element by reefing or unreefing the top and bottom layer. The profiled element is extended by a rod element which runsin the longitudinal direction of the profiled element and is used for stabilizing the aerodynamic profile. Said rod element is fastened to the top and / or bottom layer and / or a web. At least one of the reefing lines is deflected on the rod element from a reefing line section that extends from the fastening point at the first end in the transversal direction of the profiled element of the top or bottom layer into a reefing line section extending in the longitudinal direction.

Description

technical field [0001] The invention relates to an aerodynamic profile element for generating energy by means of traction, in particular for driving water vehicles, comprising: [0002] a flexible upper layer extending in the transverse and longitudinal directions; [0003] a flexible lower layer extending parallel to the upper layer and connected to the upper layer by means of a plurality of webs extending in the depth direction of the profile element; [0004] an air-filled lumen between the upper and lower layers; [0005] at least one vent for inner cavity ventilation arranged between the two mutually parallel front edges of the upper and lower layers; [0006] a plurality of pulling ropes, the first ends of the pulling ropes are fixed at spaced positions on the profile element and the second ends of which are connected with the pulling cables for connecting the profile element and the water vehicle; [0007] A plurality of furling lines with first ends fixed to the lay...

Problems solved by technology

[0015] A first problem here is that the prevailing wind conditions close to the ground make it difficult to create a stable flight attitude of the profiled elements, since the wind conditions are often weak and are moreover variable with respect to intensity and direction

Therefore, the lower the surface element flies, the more difficult it is to control
