Embodiment Construction

[0049] The principles and features of the present invention are described below in conjunction with examples, which are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0050] A fin-rudder combination self-correcting underwater vehicle, the shape structure is modeled on the shape of a flying fish, combining the characteristics of hydrofoil aircraft, underwater glider and submarine, and a combination of hydrofoil and fin rudder is symmetrically installed on the central front of the vehicle The body adopts the characteristics of hydrofoil aircraft when advancing on the water surface. The hydrofoil at the end of the rudder generates lift to reduce the forward resistance. Angle of attack, so as to realize floating and diving, hovering at any position in the water, forward and backward.

[0051] Therefore, taking into account the characteristics of the aircraft's ability to dive and rise, and to move forward and backward...

Abstract

The invention relates to a fin rudder combined self-correcting water surface and underwater vehicle, the shape structure of the aircraft simulates the appearance of the flying fish and combines the characteristics of the hydrofoil vehicle, the underwater glider and the submarine, the central front part of the vehicle is symmetrically provided with the combination of the hydrofoil and the fin rudder , when advancing on the water surface , the feature of water-wing navigation device is adopted in generating lifting force by the hydrofoil at the end of the rudder to reduce the forward resistance, and the fin rudder is flattened when submerging and floating are needed, the attack angle of the vehicle is changed by adjusting the rudder angle, so that floating, submerging, hovering, moving forward and backward at anywhere in the water are realized. The combination of propeller, fin and rudder together with the combination of all movable rudder and fin, enable the navigation device to have agood fluid dynamic layout and higher flexibility, and the navigation device can realize the free navigation underwater and on the water surface and has a self-correcting function.

Description

technical field [0001] The invention relates to a craft, in particular to a fin-rudder combined self-correcting underwater craft. Background technique [0002] In recent years, with the development of science and technology, deep-sea exploration and the development of marine resources have been paid more and more attention by various countries. Underwater vehicles can complete underwater exploration, detection and even military offensive and defensive tasks. Now that ocean development is becoming more and more important, underwater vehicles are getting more and more attention from various countries, and they play an important role in both civilian and military use. [0003] The current aircraft is divided into surface aircraft and underwater aircraft. Most of the surface aircraft use double propellers to change the course with the use of vertical rudders, and the range of activities is limited to surface navigation; while the underwater aircraft has the following types: Com...
