Embodiment Construction

[0024] The tail control surface of the uniaxial UV comprises a horizontal protrusion 1 and a vertical upper and lower protrusion 2 - stabilizers, which are formed on the tail part of the hull 3 of the subsea vehicle before the propeller 4 . Stabilizers 1 and 2 have a fixed front and a movable tail. A guard 5 for the retractable device is formed in the tail portion of the UV housing 3 . figure 1 The horseshoe-shaped vortex generated by the shield 5 for the retractable device is shown conditionally. have a winged form with variable chord length ( image 3 ) and a variable setting angle α along the perimeter of the half-ring 设置 The half-rings 6 (vortex generators) are arranged on the fixed parts of the tail horizontal and vertical rudders (not shown). The radius of the half-ring and thus its fixed position on the stabilizer corresponds to 1.2-1.3 times the radius of the shell of the subsea vehicle in the area where the half-ring is arranged, where the maximum of the incident f...

Abstract

The inventive cruciform stern control surfaces of an undersea vehicle comprise horizontal projected parts(1) and vertical top and lower projected parts (2), i.e., stabilising fins, with fixed foreparts and movable tail parts, wherein a semi-ring (6) is mounted on the fixed foreparts of the horizontal stabilising fins (1) and the top vertical stabilising fin (2), which semi-ring (6) has a wing-shaped cross-section with variable chord lengths and the steering angles of sections along the perimeter of the semi-ring (6), wherein the steering angles are selected according to the local attack angles of the inflow and the radius of sections where said semi-ring (6) is mounted on the stabilising fins (1, 2) is equal to 1.2-1.3 of the radius of the undersea vehicle hull (3) in the area where the semi-ring (6) is mounted.

Description

technical field [0001] The present invention generally relates to the field of shipbuilding and relates to the structural design of aft control surfaces of an underwater vehicle (hereinafter referred to as UV) for maintaining the stability and controllability of the underwater vehicle. Background technique [0002] Now, for the purpose of improving living conditions on cruisers, for example, the requirements for vibration and noise levels of ships have become stricter, and the operational reliability of various equipment including fishing boats and survey ships, Underwater sound-borne equipment on ships and underwater vehicles has led to the development of various methods of reducing noise emissions. [0003] It is known that the level of cavitation and vibro-acoustic properties of operating propulsion devices such as propellers of single-shaft underwater vehicles is determined by the inhomogeneity of the flow velocity field occurring at the tail. The incident flow at the p...
