Embodiment Construction

[0014] Embodiments of the present invention will be described below according to the accompanying drawings.

[0015] Such as figure 1 As shown, the high-speed ship includes a hull 1, double helical propellers 3 and 3', and an empennage helical propeller 5, which are bilaterally symmetrical at the front. The main shaft 2 is at the middle and upper part of the hull 1, and the left and right symmetrically distributed screw propellers 3 and 3' are connected with the main shaft 2 to form a front double screw propeller device. The inclination angle a of the twin screw propellers 3 and 3' is adjusted by the rotation of the drive main shaft 2 . Such as figure 2 As shown, due to the existence of the inclination angle a, the thrust of the twin-screw propeller can be decomposed into forward propulsion and upward lift. The upward lift overcomes the gravity of the hull part, thereby reducing the contact area between the hull and the water-air surface, that is, reducing the draft H, so ...

Abstract

The invention relates to a high-speed ship on the basis of double inclinable screw propellers, and belongs to the technical field of ship propulsion. The double inclinable screw propellers are symmetrically distributed on the middle upper portion of the high-speed ship and can be reasonably inclined at certain angles, so that propulsion force has upward component force and component force in an advancing direction. The upward component force overcomes a part of the gravity of the high-speed ship, the immersion depth of the ship is reduced, and the resistance on the ship is decreased; and the component force in the advancing direction pushes the ship to advance. A tail fin screw propeller is arranged at the tail of the ship, the inclination position of the tail fin screw propeller can be changed, and the tail fin screw propeller can be matched with the front double screw propellers in an equilibrium manner, so that the ship can run stably. The high-speed ship overcomes shortcomings of poor stability of equilibrium of a common high-speed ship and poor mobility of the common high-speed ship, and has the advantages of capability of running at a high speed, excellent mobility and stability of equilibrium, and the like. Besides, the high-speed ship is low in cost and has popularization value.

Description

technical field [0001] The invention belongs to the technical field of ship propulsion, and relates to a technical solution for fast and stable running of a speedboat on the sea, in particular to an external screw propeller device with an adjustable installation angle and a solution for balanced distribution of the screw propeller. Background technique [0002] For thousands of years, although ships have developed greatly, they have always been inseparable from the Archimedes principle, relying on static buoyancy to support the weight of the ship. The density of water is about 800 times that of air, and the resistance will be 800 times that of air under the same conditions. Moreover, when a ship sails on the water-air interface, waves will arise. The resistance caused by the waves is generally proportional to the sixth power of the speed, so it is indeed difficult to increase the speed of the ship. Since the biggest factor affecting the speed of displacement surface ships i...
