| 发明名称 | Deflector for marine data acquisition system | ||
| 摘要 | Deflectors configured to be attached to cables towed behind a vessel for performing a marine survey are provided. A deflector has a wing body including a first part joined to a second part to form a swept-back-wing shape, the first part and the second part being substantially coplanar. A first straight line stretching along at least a portion of a front edge of the first part makes a first angle with a second straight line stretching along at least a portion of a front edge of the second part. A third straight line stretching along at least a portion of a trailing edge of the first part makes a second angle with a fourth straight line stretching along at least a portion of a trailing edge of the second part, the first angle and the second angle being non-zero angles. | ||

| 主权项 | 1. A deflector configured to be attached to a cable towed by a vessel and configured to connect to a streamer or a source for a marine survey, the deflector comprising: a wing body including a first part joined at a joining axis to a second part to form a swept-back-wing shape, the first part and the second part being substantially coplanar and maintaining a substantially vertical orientation when towed, wherein a first straight line stretching along at least a portion of a front edge of the first part makes a first angle with a second straight line stretching along at least a portion of a front edge of the second part,a third straight line stretching along at least a portion of a trailing edge of the first part makes a second angle with a fourth straight line stretching along at least a portion of a trailing edge of the second part,the first angle and the second angle being non-zero angles,a first slot extends from the joining axis along the first part, and a second slot is connected to the first slot and extends from the joining axis along the second part, an angle between the first slot and the second slot enabling the first and second slots to remain at distances from the front edge of the first part and the front edge of the second part, respectively. | ||
