SU1459968A1 - Method and apparatus for compensating drift and increasing stability of sail ship in sailing - Google Patents

Abstract

The invention relates to the field of shipbuilding and can be used to improve the maneuverability, handling and payload of sailing ships. For this, sailing vessel I is equipped with a sailing armament 2, its hull contains a keel 3 with a shell and ballast 4, and a keel in the upper and lower parts has split wings 5 and 6. The drive for turning split wings consists of two coaxial shafts mounted on them cams. The worm wheels interacting with the worms are mounted on the upper parts of the shafts, on whose axes the flywheels of the turning of the split wings are fixed. With the help of flywheels and coaxial shafts with the cams of the upper part of the keel give a convex shape and at the same time the lower part of the keel - a concave shape or the upper part of the keel give a concave shape and at the same time the lower part of the keel - convex. 2 sec. f-ly, 3 ill. fi (L

Description

The ditch with the median plane of the sail and the direction of the roll of the sailing

vessel Cams 25 and 26 are kinematically associated with parts of a split wing on the starboard side 27, 28 and on the left side 29.30. The front edges of the wing are fixed in bearings 31 and 32-slip mounted on the vertical axis 33. The rear edges of the wing are fixed in bearings 34 and 35 slip mounted on the vertical axis 36 coinciding with the rear end of the keel of the sailing vessel 1. The turn of the shafts 14 and I5 around the axis aa leads to a change in the position of the kinematically closed parts of the split wing to the cams 25 and 26. In the zero position of the coaxial shafts, the outlines of the underwater part of the hull of the sailing vessel are characterized by symmetry (Fig. 2a, hf, h), and when the coaxial shafts are rotated from the zero position, asymmetry of the outlines of the underwater part of the hull appears, for example, on the left side (26,) , where h ;,, hf, are the distances from the axis of symmetry to the edges of the outlines of the right and left sides.

At the same time, the asymmetry of the split flap can be accomplished by securing the lower parts of the shafts 14 and 15 to the front edges of the wing. Fig. 3 shows the wing profile (PC), the construction of which assumes that the axis of the shafts 14 and 15 passes through point A of the profile. In this case, the lower parts of the coaxial shafts 14 and 15 are rigidly fastened to the front edges of the wings 5 and 6. When you turn the coaxial the shaft link around its axis, for example, counterclockwise (Fig. 3a), the split hydrofoil changes its profile so that the profile asymmetry appears from the starboard of the sailing vessel. At the same time the front part

the vessel. Using the handwheels 20 and 21, the asymmetry of the profiles of the split wings 5 and 6 is adjusted.

15 handwheel 20 acceptable characteristics of the drift, and with the help of the handwheel 21 - check the sailing vessel. For the case shown in figure 1, in order to compensate for the drift, the coaxial shaft

20 14 is turned clockwise, and the coaxial shaft 15 is turned to lock the sailing vessel (while under sail) counterclockwise.

25 A method and apparatus for its implementation will allow to increase the maneuverability of a darusn vessel due to the choice of characteristics of the magnitude and direction of the drift. The possibility of spraying a ship in a wide range of wind loads makes it possible to increase the navigability of a sailing ship. Achieving stability when sailing due to hydrodynamic lifting 2g of force allows to reduce the weight of the ballast in the lower end of the ship sailed, which will increase (by an amount equal to the decrease in weight of the ballast) sailing payload

40 ships.

Using the handwheels 20 and 21, the asymmetry of the profiles of the split wings 5 and 6 is adjusted. the handwheel has 20 acceptable drift characteristics, and with the help of the handwheel 21 it is suitable for the sailing vessel. For the case shown in figure 1, in order to compensate for the drift, the coaxial shaft 14 is turned clockwise, and the coaxial shaft 15 is turned around to lock the sailing vessel (while under sail) counterclockwise. The method and apparatus for its implementation will allow to increase the maneuverability of the darusn vessel due to the choice of characteristics of the magnitude and direction of the drift. The ability to spawn a ship in a wide range of wind loads allows an increase in sailing ship speed.
