The invention provides a resistance reduction-propulsion integrated structure of a manually-ventilated supercavitating
torpedo. A traditional
torpedo structure is changed, a
cavitation bubble generator on the head portion of the traditional structure is omitted, and the head portion of the
torpedo is made to be a plane; an engine jet
pipe located on the
tail portion of the torpedo is omitted, and four
small engine jet pipes are arranged at the front end of the torpedo and evenly distributed in the upper direction, the lower direction, the
left direction and the right direction; the included angle between the central axis of each jet
pipe and the central axis of the torpedo is 10-15 degrees; by the adoption of the structure, the situation that the movement form is instable due to the fact that the front portion and the rear portion of the torpedo bear thrust at the same time is avoided, and meanwhile uniform thrust can be provided. The resistance reduction-propulsion integrated structure of the manually-ventilated supercavitating torpedo can be applied to low-speed movement and can also achieve high-speed movement; during low-speed movement, natural
cavitation bubbles cannot be formed on the plane of the front portion of the torpedo, the engine jet pipes inject air so that a ventilation
cavitation bubble can be formed nearby, the resistance of the portion covered with the
cavitation bubble is reduced, the resistance reduction effect is achieved, and a propulsion
system and a resistance reduction
system of the torpedo are combined.
