An airfoil system is used with an array of towed marine cables to provide downward, upward or lateral lift to the array. The airfoil system may be coupled with the cable and configured to bias the underwater payload toward a target position. The airfoil system may include a set of airfoil sections each having a leading edge that collectively defines an angle of attack and a set of through cables supporting the set of airfoil sections within the airfoil system. A subset of the through cables of the set of through cables is arranged through a front half of the set of airfoil sections. The subset of through cables may be selectively tensible and manipulated to define a tensioned through cable of the subset of through cables as offset from a chord defined between any leading and trailing edges in the airfoil section. Thus, the airfoil system may cause one or more angles of attack for the set of airfoil sections based on rotational constraints defined by tensioned ones of the through cables.

    一种翼型系统与拖曳式海洋线缆阵列一起使用,以向阵列提供向下、向上或横向升力。该翼型系统可与线缆联接并构造成将水下有效载荷朝向目标位置偏置。该翼型系统可包括各自具有共同限定攻角的前缘一组翼型部段和支撑翼型系统内的该组翼型部段的一组贯通线缆。该组贯通线缆的贯通线缆的子集布置成通过该组翼型部段的前半部。该贯通线缆的子集可能够选择性地张紧,并且能够操纵以将贯通线缆的子集中的张紧的贯通线缆限定为从限定在翼型部段中的任何的前缘和后缘之间的翼弦偏移。因此,翼型系统可基于由贯通线缆中张紧的贯通线缆限定的旋转约束来为该组翼型部段引起一个或多个攻角。
