摘要： A trawl door (37) comprising a flow booster (8) and an overlapping sequence of several very slender hydrofoils (2) is disclosed, the flow booster (8) being shaped as a thick hydrofoil with an internal cavity (32), being aerodynamically inefficient on its own with a bulky relative thickness larger than 24 % and being arranged to be positioned substantially below the rear part of the trawl door (37), in such a way that the flow booster (8) forms a structurally connected integrated part to the hydrofoils (2) and impacts the upstream flow forcing it into a velocity boosted region (28) upstream of the flow booster (8) and to the pressure side (31) of the conventional part of the trawl door (1), such that the flow is pre-accelerated prior to running through the conventional trawl door channels (29) between the hydrofoils (2). Furthermore, a flow booster (8) for such a trawl door (37) and some uses of such a trawl door (37) are disclosed.

摘要： The disclosure relates to a trawl door (2) comprising a plurality of hydrofoils (9), one or more shutters (20) extending in the longitudinal direction of the plurality of hydrofoils, and drive means (21) for rotating the shutters about a pivoting axis, wherein the drive means are arranged to rotate the shutters between a disengaged position and an engaged position. The disclosure further relates to the use of a set of trawl doors and a round-shaped elongated element for a trawl door.

摘要： A multi-foil lift force creator (1) for a fishing trawl is disclosed, said multi-foil lift force creator comprising a plurality of hydrofoil elements (2) aligned in a stacked manner and designed to be arranged between and attached rigidly at both ends to a spherical buoyancy element (9) for being mounted on a fishing trawl head rope (11), wherein the hydrofoil elements are shaped to deflect the water during towing of the trawl net (12) in such a way that the hydrodynamic force thereby created complements the buoyancy force from the buoyancy elements, and wherein, rather than having butt ends, the hydrofoil elements join smoothly to multi-foil end caps (5) fitting tightly around the two buoyancy elements at the ends of the multi-foil lift force creator, respectively. Furthermore, a multi-foil lift force creator assembly comprising such a multi-foil lift force creator and the use of such multi-foil lift force creator assemblies during trawling operation are disclosed.
摘要翻译：公开了用于钓鱼拖网的多箔升力创建器（1），所述多箔升力创建器包括多个水平元件（2），所述多个水翼元件（2）以堆叠方式对齐并设计成布置在两端之间并且刚性地附接到用于安装在钓鱼拖曳头绳索（11）上的球形浮力元件（9），其中水翼元件成形为在牵引拖网（12）期间偏转水由此产生的流体动力与来自浮力元件的浮力相互补充，并且其中，水翼元件不是具有对接端，而是平滑地接合到端部上的两个浮力元件周围紧密配合的多箔端盖（5）多箔升力生成器的分别。此外，公开了包括这种多箔升力生成器的多箔升力生成器组件以及在拖网操作期间使用这种多箔升力生成器组件。
