ЛЕГКАЯ ФОРМОВАННАЯ РАСПОРНАЯ ДОСКА ТРАЛА ДЛЯ ВЫСОКОСКОРОСТНОГО ТРАЛЕНИЯ, ОБЛАДАЮЩАЯ ПОВЫШЕННОЙ ГИДРОДИНАМИЧЕСКОЙ ЭФФЕКТИВНОСТЬЮ, СПОСОБЫ ЕЕ И ИСПОЛЬЗОВАНИЯ И ИЗГОТОВЛЕНИЯ

摘要

FIELD: mechanics. ^ SUBSTANCE: proposed otter trawl incorporates one or two slats arranged with their front edges in compliance with the position of the front edge of one primary deflector that features a shape wherein the said deflector outer side surface has larger curvature than the inner side surface. The said deflector profile thickest part is arranged ahead of the center. The outer side surface is bulged while the inner side one is concave. The proposed otter trawl is made from synthetic material containing a polymer material mixed with elastomer. The said otter trawl synthetic part takes up whatever impacts without damages. ^ EFFECT: light-weight, high-strength design of otter trawl along with ease of manufacture and use. ^ 58 cl, 5 dwg
