Description

The invention relates to shipbuilding, to sailing craft, mainly to sailing racing yachts.

Sailing ships are known in which ballast is used to increase stability during sharp courses. Such vessels are heavy and usually slow moving due to the presence of ballast.

Racing huts-daggers are known, in which a payload crew is used as a moving ballast. Such vessels are not stable enough.

One of the varieties of dinghies is known - a sailing board, selected as a prototype, containing a sail in the form of a mast-wing, rotatable and tilted relative to the hinge at its lower end, located on the deck, a fin keelboard is mounted on the bottom of the hull.

Although in order to increase the stability of the sailing board, in addition to the moving ballast (crew), it uses the mass of the mast-wing, which is tilted to the wind, the sailing board also has insufficient stability.

The purpose of the invention is to reduce pitching from torque at sharp heading angles.

This goal was achieved due to the fact that the sailing craft contains a sail in the form of a mast-wing, rotatable and tilted relative to the hinge at its lower end, located on the deck, a fin keelboard is mounted on the bottom of the hull.

What is new is that the wing-mast is made with an upper additional wing-mast, the middle part of which is connected by a universal joint to the upper part of the main wing-mast. The vertical axis of this universal joint is located at the front edge of the additional mast-wing along its span. Technical solutions with a similar combination of features are unknown to the authors. The increase in stability is achieved through the more efficient use of the weight of the tiltable mast-wing for detachment. The articulation of two parts of the wing mast allows you to carry overboard its greater weight on a larger shoulder, thereby increasing stability. In this case, the upper part of the mast-wing can maintain a vertical position, i.e. part of the windage can work with the greatest efficiency, and the heel can be kept zero, which, when the keel-vault is vertical, allows the hte to have minimal resistance to forward movement and ensures its minimum drift under

wind i.e. overall yacht efficiency in a sail-hull-keel (dagger) combination is increased.

The drawing shows a diagram of the device of the proposed sailing craft - racing hty-dinghy.

The racing hta contains a body 1, on the bottom 2 of which a fin keel (daggerboard) 3 and a steering wheel 4 are installed. On the deck 5, using the universal hinge 6, the lower end of the lower part 1 of the wing mast is mounted with the possibility of rotation around the axis (Yi-Yi ), which extends closer to the leading edge along the span and with the possibility of tilting the lower part 7 of the mast-wing (around the Xi-Xi axis) to the left and right sides, The middle of the leading edge of the upper part is attached to the upper end of the lower part 7 using a universal joint 8 9 mast wings with a possibility of turn in the circle of the axis (Y2-Y2) extending closer to the front edge and along the span of the upper part 9 of the mast-wing and with the possibility of tilting it relative to the axis (Y- | -Yi) of the lower part 7 of the mast-wing left and right. The axes of both 6, 8 universal joints are connected to the drives of the rotation mechanisms 10.

The device operates as follows. During hta during sharp courses, both parts of the wing-mast — the upper 9 and the lower 7 — are turned around the vertical axes Y2-Y2 and YI-YI using the rotation mechanisms 10, setting the optimal angle of attack for each part 7, 9. When the wind is strengthened and a roll occurs on one side using other turning mechanisms 10, the lower part of the wing-mast, turning around the horizontal axis Xi - Xi, is tilted into the wind, thereby compensating for the torque by the weight of the tilted mast-wing. In this design, it is possible to increase the weight of the mast carried. For this, the upper part of the mast-wing is rotated around the horizontal axis (X2-X2) in the direction opposite to the inclination of the lower part of the mast-mast 7 to a vertical position. Moreover, the upper part 9 of the mast-wing operates under the most favorable aerodynamic conditions. When changing the tack, the same operations are performed on the other side.
