Embodiment Construction

[0024] The tail control surface of the uniaxial UV includes a horizontal protrusion 1 and a vertical upper and lower protrusion 2-a stabilizing wing, which is formed on the tail part of the shell 3 of the underwater vehicle before the propeller 4. The stabilizer wings 1 and 2 have a fixed front part and a movable tail part. The guard 5 for the retractable device is formed in the tail part of the UV housing 3. figure 1 The horseshoe-shaped vortex generated by the guard 5 for the retractable device is shown conditionally. Has a wing-like form with variable chord length ( image 3 ) And the variable setting angle α along the circumference of the half ring Set up The half-ring 6 (vortex generator) is set on the fixed part of the tail horizontal and vertical rudder (not shown). The radius of the half ring, and therefore the radius of its fixed position on the stabilizer wing, corresponds to 1.2-1.3 times the radius of the subsea vehicle shell in the area where the half ring is pro...

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 the tail control surface of an underwater vehicle (hereinafter referred to as UV), which is used to maintain 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 the vibration and noise levels of ships have become more stringent, and the operational reliability of various equipment, including fishing vessels and survey ships, has been improved. The underwater sound transmission equipment on ships and underwater vehicles has led to the development of various methods of reducing noise. [0003] It is known that the level of cavitation and vibro-acoustic characteristics of propellers of operating propulsion devices such as uniaxial subsea vehicles is determined by the unevenness of the flow velocity field occurring at th...
