Description

2. A rigid sail containing a swivel-mounted mast and rigid shaped sections of the sail / interconnecting is also distinguished by the fact that, in order to improve the aerodynamic quality of the rigid sail, the mast is equipped with two-way guides on two mutually opposite sides mi slider odd

the hinges of which are connected to rigid shaped sections of the sail, which are hingedly connected so that they can be folded in two packages onto the base of the mast as the sliders move along the rods,

 3. Sail on PP, 1 and 2, about t l and: due to the fact that in the corners: of its profiled sections are installed locking devices.

   The invention relates to construction, mainly to sailing vessels, and can be used in their design and construction.

Closest to the invention of the technical nature is a rigid sail / containing a telescopic mast with a swivel base and rigid shaped sections of the sail interconnected l.

However, in the known device the aerodynamic quality of a hard sail is not equal in its height .. In the lower part, the sail is lower in value than in / upper part for 1 account of the greater thickness of the sail profile below.

The purpose of the invention is to improve the aerodynamic quality of the hard sail.

The goal is achieved by the fact that in a rigid sail containing a telescopic mast with a swivel base and rigid e-sectioned sections of the sail interconnected according to the first variant. mutually opposite sides of the mast with the possibility of folding them in two packets based on the mast / and the upper sections of the sail are hinged to the top of the mast.

The second embodiment of a rigid sail (different from the first one) is that in a rigid sail the mast is provided with two guide rods with two sliders located on two mutually opposite sides, the odd hinges of which are connected to rigid rigid sections napyt; a, pivotally connected to each other along chords of their streamlined profiles and-performed with the possibility of putting them in two packages on the base of the mast when moving the sliders on the rods m. In addition, in both cases, in order to increase the stiffness n k kr t tca of the wing, locking devices are installed in the corners of the profiled sections for rigid connection of the sections in a vertical working position.

Fig. 1 schematically shows: the beginning of the folding of a rigid sail with a telescopic retractable mast; Fig. 2 illustrates the moment of folding of the rigid sail mounted on a non-retractable mast; on fig.Z and 4 rigid sail in the folded position (in the first and second versions); Fig. 5 shows the hinge assemblies of the shaped sections of the sail.

In the first embodiment (Fig. 1), the rigid sail contains a turning base 1, on which a telescopic rotating mast 2 is mounted. On its top are hinges 3 / to which the profiled sections 4 are attached. These sections are connected with each other by means of hinges 5, B the corners of the profiled sections are locking device 6.

The device works as follows.

1 In idle state, the profiled sections 4 / pivotally interconnected / lie on a rotatable base 1 / and the telescopic mast 2 (truss or tubular section) is folded and retracted beneath the deck.

The hinges 3, located on the top of the mast, are connected to the hinges of the upper edge of the first top-section sections. (FIG. 3). FORMATION; a rigid sail telescopic mast 2 is extended from the base -1, while the profiled sections 4 occupy a vertical position (figure 1). Then, the locking devices 6 rigidly connect all the profiled sections that form the national sail of the metric profile.

In the second variant (Fig. 2), the rigid sail contains a rotating support 7, on which a non-retracting mast 8 is installed and flat scarvies 9 are attached after

The profiled sections 4, on two mutually opposite sides of the mast 8, are installed guide rods 10, in which sliders 11 are located, connected to the loops of the two sections, when folded facing the mast (Fig. 5).

The device works as follows.

In the non-working state, the profiled sections .4 lie on the rotatable base 7 on both sides of the mast. Dp formation of rigid sail sliders 11, tt which are attached to the upper sections, are lifted by a cable or in some other way up the mast. In this case, the profiled sections take a vertical position and the locking devices 6 rigidly connect all sections.

In both variants, the reduction of the wing-sail area can be done in parts, in this case the locking devices 6 of the required number of lower sections are disconnected and the sail is lowered down, and the disconnected sections are folded on a turning base 1 or 7.

The positive quality of the proposed technical solution is that the hard sail made up of profiled sections along its height has the same thickness and therefore the aerodynamic quality of this sail is higher compared to

the prototype.

I. ,

In addition, the proposed design of a rigid sail allows the ship-; to carry out its full cleaning, which in stormy conditions: {lhashan improves ship control and reduces fuel consumption when the ship is moving under the engine.
