Problems solved by technology

[0002] At present, the thrust propellers of submarines are all installed at the tail, and the seawater provided to the propeller recoil is limited at this part, because the hull moves forward, and the vacant position at the tail must be filled with seawater, and the propeller absorbs seawater recoil at this part , it competes with the seawater filling the space for water source, which limits the power of the propeller; the water displacement cross-sectional area of ​​a single or double tail propeller is too small compared with the cross-sectional area of ​​a submarine, and the thrust at the high speed of the critical cavitation is also far away. Not enough thrust for a submarine to submerge at a high speed above 60 knots; the steering of the submarine depends entirely on the tail rudder, which is slow and clumsy

Embodiment Construction

[0009] The submarine bow (5) must be a bullet type, and the conventional water drop type submarine bow must be refitted with a bullet-type fairing.

[0010] Cancel the thrust propeller of the stern (6), so that the seawater can more fully fill the stern space, so as to reduce the dragging force of the seawater on the stern, and also reduce the range of sea water stirred when the submarine is submerged; in the hull (4) The arm-mounted propeller (1) is installed on the outer wall and driven by a speed-regulating motor (2). The arm-mounted propeller is preferably a three-blade propeller. Because there is sufficient seawater for driving, the torque must be efficiently used to generate thrust; the number of arm-mounted propellers to be installed must be According to the comprehensive consideration of submarine displacement, design speed, propeller diameter, etc., but the total effective water displacement cross-sectional area of ​​the propeller must exceed the cross-sectional area o...

Abstract

The invention discloses a high-speed, low-noise and maneuverable submarine. A plurality of arm-hung propellers driven by a motor are arranged on the outer wall of a submarine body, and together propel the submarine to realize the low-noise and high-speed under-water movement of the submarine; and the totally eight arm-hung propellers arranged on the upper, lower, left and right sides of the front and rear parts of the submarine body can rotate within 360 degrees to work around hanging arms, thereby realizing the vertical ups and downs, sidesway, back-running, in-place turning-around and maneuverability of the submarine. The invention is suitable for manufacturing the high-speed, low-noise and maneuverable submarine.

Description

Technical field [0001] The invention relates to a high-speed, low-noise, maneuverable and flexible submarine. Background technique [0002] At present, the thrust propellers of submarines are all installed at the tail, and the seawater provided to the propeller recoil is limited at this part, because the hull moves forward, and the vacant position at the tail must be filled with seawater, and the propeller absorbs seawater recoil at this part , it competes with the seawater filling the space for water source, which limits the power of the propeller; the water displacement cross-sectional area of ​​a single or double tail propeller is too small compared with the cross-sectional area of ​​a submarine, and the thrust at the high speed of the critical cavitation is also far away. Not enough thrust for a submarine to submerge at a high speed above 60 knots; the steering of the submarine depends entirely on the tail rudder, which is slow and clumsy.
