High-speed, low-noise and maneuverable submarine

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.
