A Vertical Steerable Steerable Underwater Towed Body

Abstract

The invention discloses a vertical type operable underwater towed vehicle with a stable course. The vertical type operable underwater towed vehicle comprises torpedo-shaped floating bodies, wing-shaped inclined struts, a fixed horizontal wing, a fixed vertical wing, a fixed horizontal tail, a fixed vertical tail, a course changing controller and a main cavity, wherein the main cavity is in a shell structure with a vertical type long streamline-shaped appearance; the two torpedo-shaped floating bodies are distributed on the two sides above a vertical symmetrical face of the main cavity; the fixed horizontal wing is a symmetrical wing shape and is connected with the two torpedo-shaped floating bodies in the horizontal direction; one fixed vertical wing is arranged between the middle part of the fixed horizontal wing and the main cavity in the vertical direction; the wing-shaped inclined struts are distributed among the torpedo-shaped floating bodies and the main cavity; one ends of the wing-shaped inclined struts are connected with the torpedo-shaped floating bodies and the other ends of the wing-shaped inclined struts are connected with the upper part of the main cavity; the fixed horizontal tail and the fixed vertical tail are arranged on the rear part of the main cavity. The towed vehicle is simple in appearance, good in course stability, strong in automatic stabilizing capability, convenient in posture control, high in manipulation efficiency, capable of being manipulated in a plurality of degrees of freedom, and strong in practicability, and a control mechanism is simple.

Description

technical field [0001] The present invention relates to an underwater towed body, in particular to a vertical course-stable and steerable underwater towed body, which is a towed movement carrier used for an underwater seawater physical and chemical parameter detection device. Background technique [0002] The steerable underwater towed body is a dynamic detection device applied to underwater dynamic environment monitoring and information collection of underwater physical and chemical parameters. The system usually consists of a towed cable, an underwater towed body including the main cavity, and an attitude control mechanism. Composition, the main cavity is the main component of the steerable underwater towed body. The main cavity can be equipped with different types of chemical or physical parameter monitoring sensors according to different detection requirements. The operator on the workboat can issue specific control instructions to the attitude control mechanism of the ...

Problems solved by technology

The main defects of this kind of drag body in the form of a single cylindrical body or a flat horizontal airfoil body are: the swing damping of the drag body is small, the autonomous stability is insufficient, the heading stability is poor, and the control method is single

On the other hand, some commercial light towed bodies on the market are difficult to be satisfactorily applied in actual towed observation operations due to single control action, difficulty in ensuring their attitude stability, and less control degrees of freedom.
