(57) Abstract:

The invention relates to shipbuilding and can be used to improve ease of use, movement and maneuverability monohull sailing vessels. The above method is that the form of the hydrodynamic lift force, which relative to the axis (shaft) of steps mast of a sailing vessel is fully or partially ensures a stable position of the mast in position on the roll. The device for implementing the method of the sustainability of the mast of a sailing vessel contains steps with a fixed mast with a sail - aerogram with variable geometry. Steps provided with a shaft (shaft) bearings. Mast sailing ship made with the optional underwater part with additional Schwerte-hydrocream with variable geometry. Axis (shaft) of steps rigidly fastened to the mast of a sailing ship in between the aerial and gidroksilnami and provides a low resistance rotation, zakryvanii mast on the left and right side of the hull of a sailing vessel. The technical result of the implementation group of the invention is to improve the efficiency rigged new types of dinghies and sailing boards with polystryrene and can be used to improve both performance and maneuverability of sailing ships.

Widespread way to ensure the sustainability of the mast of a sailing vessel in position in the plane perpendicular to the median plane of the hull of a sailing vessel by forming forces: reactions in support (stepsa) mast and standing rigging, rigidly attached to the hull of the sailing vessel ([H1] K. H. Marquardt's "Mast, rigging and sails of the ships of the eighteenth century", page 44 Leningrad Shipbuilding 1991; [H2] Bob bond Reference yachtsman page 44 Leningrad Shipbuilding" 1989) that hold the mast in position.

When this rigid fastening the mast to the hull of the sailing vessel leads to the roll of the hull of a sailing vessel when sailing and, as consequence, to decrease in speed because of the larger amount of resistance to movement heeled shoes of the hull of a sailing vessel.

The flatness of the hull of a sailing vessel, providing stability when sailing when rigidly attached to the hull of a sailing ship's mast, it is customary to provide optimal from the point of view of speed sailing vessel means: increase the width of the enclosure or installing keel with ballast, "eat" moreover, a significant fraction of the useful displacement sailing ship.

System Case-Sail-Man" starts to work as soon as the sail of a sailing Board is filled with wind. Man is a sailor in the framework of Case-Sail-Man" plays the role of an active force, stabilizing the motion of the system. In this case it is possible to optimize the dimensions of the hull of a sailing Board with regard to its speed qualities, "placing the responsibility for the stability of the sailing Board on the part of the system "Body-Sail-Person", "Person"-sailor [L3].

We'd like to add that "the role of active forces" received the man-yachtsman in the system "Body-Sail-Man, speed limits and lavirovaniya opportunities sailing Board physical abilities: strength, weight, speed, physical reactions, endurance I had unevenness sailing ship.

The objective is achieved by forming torque of the hydraulic lifting force, the magnitude and direction of which is fully or partially provides the working position of the mast of a sailing vessel on the roll. Thus completely or partially exempt from maintaining the mast in position to roll the hull of a sailing vessel or a sailor.

The device for implementing the method supply stepson with the axis (shaft) bearings and a mast with a sail-aerogram with variable geometry, with additional underwater part with additional Schwerte - hydrocream with variable geometry, the axis (shaft) of steps rigidly fastened to the mast of a sailing ship in between the aerial and gidroksilnami, with the possibility of rotation of the mast about an axis (shaft) of steps, mounted in bearings, zakryvanii on the left and right side of the hull of a sailing vessel.

The Proposed "Method. . . and device for its implementation" allow to generate additional Schwerte hydrodynamic lifting force for full or partial compensation screenwasher moment caused by work rigged on the go sailing sailing ship.

In Fig.1 shows a diagram of IP is and on the proposed "Method. . . " In Fig.3 proposed classification of devices for implementing the Method of ensuring the sustainability of the mast of a sailing vessel...". In Fig. 4, 5, 6 examines the specific embodiment of the device with the angle of attack of additional Schwerte, independent of the roll angle of the mast (). In Fig.7, 8 shows the kinematic diagram and example design sailing Board with = (), nonlinear dependence (). In Fig.10, 11, 12, 9 analyzes the device with a linear dependence (). Fig.13, 14, 15, 16, 17 examples device = (K). Fig.18, 19, 20, 21, 22 and 23 shows a device with a variable dependency type = (;).

The Method of ensuring the sustainability of the mast of a sailing vessel in position on the roll" with the prevailing approach rigged sailing ships can be considered from the point of view of further development of ideas about sailing vessel, as a system of hydro-aerocrine (see , for example, [L4] C. M. Borisov "Sail boat" Leningrad, "Shipbuilding", 1985, page 4-12; [C5] Reference malotonnazhnogo shipbuilding" compiler, B. Mordvinov, Leningrad, "Shipbuilding", 1988, page 162, Fig.7.1).

Indeed, providing the mast of a sailing ship underwater part with additional Schwerte and the axle (shaft) with the measured geometry, we can get when driving under the sails of a sailing vessel, balanced system Mast-Sail-Additional Schwerte", not destitute in the conventional rigid fixing of the mast to ensure the operating position rigged to roll. Component of the aerodynamic lifting forces generated during operation rigged, (Fig.1) attached to the center of the sail 1 (CPU) 2 sails, causes zakryvajuschii moment about an axis (shaft) of steps 3, which proposed "the Way..." compensated fully or partially moment hydrodynamic lifting force generated with respect to an axis (shaft) of steps 3 additional Schwerte 4.

In contrast to the scheme in Fig.7.1 page 162 [C5] on the proposed "Way..." use two gidroksila: additional Schwerte 4 (Fig.1) with variable geometry: with the possibility of changing the magnitude and direction of the angle of attack (Fig.2 POS.5) and Schwerte 6 (Fig.2) installed in the median plane (DP) 7 housing 8 of a sailing vessel, the surface of which is the center of lateral resistance (CBS) 9. The Schwerte 6 (Fig.2) is designed for condensing drift sailing ship. In Fig.2 the change of angle of attackithe magnitude and direction exercised by povtoram simme the C5], where the system hydroaeroplanes with hydrocream intended solely to compensate for the drift of a sailing ship.

The Method... allows you to generate hydrodynamic lift force F1(i), the value of which is fully or partially provides a stable working position of the mast of a sailing vessel to roll either independently, or depending on the angle and direction of tilt of the mastj(Fig.1) relative to the hull of a sailing vessel. In this regard, "the Way..." assumes or rejects the rigid relationship between the magnitude and direction of the roll angle of the mastjsailing vessel with respect to its housing, for example, around the axis (Fig. 2) and the value of the hydrodynamic lifting force (Fig.1) formed on the additional Schwerte (POS.4 of Fig.1, POS.5 of Fig.2).

In Fig.3 shows scheme 1, can be classified in principle, the implementation of the Method. . . ". In Fig.3 device ensure the sustainability of the mast of a sailing vessel is conventionally denoted by the abbreviation WOES.

Taking into account that (see Fig.1):

- defined "Person"-the yachtsman in the process control sail rigging.

"The only way to ensure stability of the mast of a sailing vessel in position on the roll" version of the formula 2 can be implemented using the device, the kinematic scheme of which is shown in Fig.4. Kinematic diagram of Fig.4, "projected" on a sailing vessel of Fig.2, leads to a "continuation" of the mast 10 (Fig. 2, 4), to the emergence of its underwater part of the axis 11 (Fig. 4) (axis Fig. 2) with bearings, which provide additional Schwerte 5 (Fig.2, 4) can be rotated more Schwerte 5 around the axis 11 (Fig.4) (axis Fig.2).

The mast 10 is rigidly fastened to the axle 3 steps mounted in bearings 12, 13, fixed to the body of the sailing vessel 8 at the bottom of the "T"-shaped in plan Sortavala well 14 (Fig.2). Additional Schwerte 5 is rigidly connected with the hub 15 of the worm worm wheel 16 pairs with a single-thread worm 17 (Fig. 4). On the axis of the research Institute of the arm 19 turn additional Schwerte 5 around the axis 11 at an angle of attack (10-12).

The mast 10 sailing vessel can be mounted on right or left side of a ship sailing around the axis of steps 3 anglej. Watch what will depend on the roll angle of the mastj. In Fig.2 sailing rig sailing vessel equipped with a mast 10 with the upper 20 and lower 21 crispini, guys 22, 23 and sail 2. The lower caspica 21 provided in the form of a rigid beam, rigidly fastened to the mast 10. On the bottom crespia 21 fixed shrouds 22, 23. The lower caspica 21 elastically connected with the elastic element 24 (Fig.2 elastic element 24 is shown in the form of a spring) with housing 8 of a sailing ship. Thus, the roll angle of the mastjcaused by forces arising from the work of sailing arms (for example, in Fig.1) will determine the deformation of the elastic element 24 and its reaction to zakryvanii mast, strength, Power, in turn, will cause the roll body 8 sailing ship (the force in Fig.2 conventionally not shown).

It is obvious that the mast 10 sailing vessel can be tilted to the right or left side of a ship sailing around the axis (the axis in Fig.2) steps 3 depending on the tack, which is a sailing vessel under sail. Team sailing vessel by rotating the handle 19 of the drive worm pair of "arbitrariness" dopustimoe) (5)

and therefore has a principle possibility of smooth adjustment of the magnitude and direction of the hydrodynamic lifting force regardless of the roll angle of the mastj(remember .

In this case, the crew of the sailing vessel will be to find the value of angle of attackiadditional Schwerte 5 (Fig.2, 4), in an effort to compensate for the tilt of the mast 10, and hence to reduce the reaction of the elastic element 24, the force to a minimum. This in turn will lead to minimize roll of the hull of a sailing vessel 8.

To prevent oscillations of the mast 10 in the process rigged under the influence of variable wind load and pitching of the hull of a sailing vessel is resiliently mounted on the axis of steps 3 mast 10 is deformed by using the dampers 25, 26. The compensation of the drift of the sailing vessel is provided in the usual way using Schwerte 6, installed in a "T"-shaped sortova the well 14 (Fig.2).

In Fig.5 (conventionally, the components shown transparent) the detail designs rigged sailing vessel, corresponding to the kinematic diagram of Fig.4. Here the mast 27 is equipped with the top 28 and bottom 29 crispini with guys 30 and 31 and past the shroud plates 32 (guy-Putins starboard condition is Yong additional Schwerte 36. In Fig. 5 shows additional Schwerte 36 with bullboy 37 to increase the hydrodynamic quality of additional Schwerte, and (a particular case of implementation of the Method...") for placement of ballast, based on the provision of primary, static stability of the mast of a sailing vessel, in the absence of progress. Additional Schwerte 36 is rigidly connected with the hub 38 of the worm wheel 39 of the worm pairs with a worm 40 on the axis 41 which is mounted the handle 42 of the manual actuator which pivots additional Schwerte 36 at the corners, limited slots 43 on both sides of the hub 38 (anglei(0,(10-12)). Through the slots 43 passes axis steps 44, mounted in the center plane 7 of the sailing of the vessel (see Fig.2). Axis steps 44 mounted in bearings 45, 46 fixed at the bottom of the "T"-shaped Sortavala well 14 (Fig.2). On-the-go sailing crew sailing vessel by rotating the handle 42 provides the installation angle of attack 0additional Schwerte 36, in which the roll of the mast 27 is equal to = 0. The lower caspica 29 rigidly mounted on the mast 27 and elastically connected with elastic links 47, 48 with the hull of the sailing vessel 8 (Fig.2, 5). On the bottom crespia 29 fixed shrouds 30, 31 with a guy-the shroud plates. In addition, the lower karst is the Sol with the axis 44 of steps. Arising in the process rigged the moments of forces cause bending of the mast 27 around the axis of steps 44 in bearings 45, 46. The lower crespino 29 provided with flanges 51, 52 for attaching the shock absorber piston rod 53, 54 and bolts of the clamps 55, 56 with the "sheep" 57, 58. The bolts of the clamps 55, 56 pass through the slots 59, 60 in the flanges 61, 62, rigidly fastened to the hull of the sailing vessel 8. By means of bolts 55, 56, puff "lambs" 57, 58 flanges of the lower crispity 51, 52 may be rigidly fixed relative to the flanges 61, 62, and hence relative to the housing 8 of the sailing vessel. When Roseximbank the flanges 51, 52, 61, 62 mast 27 "acquires" "freedom": the ability to bend to the left and right side of a ship sailing around the axis of steps 44 (Fig.5). In this case, the sailing rig sailing ship works with formation of a hydrodynamic lifting force on the basis of additional Schwerte 36, is rotated about the axis 33 on the corneri.

In Fig.5 POS.63 indicated Schwerte, designed to compensate for the drift of a sailing ship. Equipment Schwerte 63 axis 64 and the bearings 65 and 66 and the mechanism of reversal of Schwerte 63 on the angle of attackg(of Fig.5 the mechanism of reversal of Schwerte 63 conventionally not shown) allows you to adjust the magnitude of the drift sailing solenoi the plane of the body.

At a fixed bottom crespia 29 relative to the flanges 61, 62 ("sheep" 57, 58 are tightened) sailing rig sailing ship begins to work according to the traditional scheme (see Fig.6). Here the mast 67 is rigidly fixed to the hull of the sailing vessel 68 stepsa 69 using cables 70, 71 and crispity 72. In this case, the sailing arms can call the roll of the hull of a sailing vessel. By controlling the angle of attackiadditional Schwerte 36 (Fig.5) (Fig. 6 - not shown), it is possible to control the amount of roll of the hull of a sailing vessel. In this case, the control on the "drift" is produced by Schwerte 63. (Fig.5).

In the considered case, the stability rigged sailing vessel underway under sail is provided by forming dosed largest and the desired direction of the hydrodynamic lifting force, which relative to the axis of steps allows to compensate creasie moments. In connection with the use considered, you are the principal possibility to optimize the dimensions of the hull and rigged sailing ship, from the point of view of its speed and maneuverability.

Device driver D. P.F. can be recommended for vodosbor CLASS="ptx2">

A group of devices indicated in scheme 1 of Fig.3 as WOMPS with driver D. P.F. can be recommended for implementation primarily to increase capacity and efficiency rigged sailing boards. For design requirements were taken into account:

1. The increase in "power" sailing arms should not cause overloads yachtsman related to the management of the sailing Board.

2. The control algorithm sailing Board using the proposed Method. . . " should be very close to the control algorithm "normal" sailing Board (see, for example, pages 89-130 [L3]).

3. Since both hands of the sailor most of the time melting on a sailing Board under sail busy running sail rigging, all management operations more Schwerte:

3.1. translation of additional Schwerte in a position to pass on melkovodyu;

3.2 translation of additional Schwerte in one of the provisions for compensation planning" to "mostly" Schwerte;

3.3 reverse and switching speed - ratio transmission from shaft steps mast to the shaft of additional Schwerte;

these operations would be "to entrust" the feet of the sailor.

In ustroystva relative to the hull of a sailing vessel. That is, there is a single phase line:

(6)

In principle, the dependence of coal attack additional Schwerte from closing angle of the mast of a sailing vessel: (a) may be non-linear and linear.

In Fig. 7 shows the kinematic diagram of the device for implementing the Method. .. "in which the dependence of the angle of attack iadditional Schwerte from the angle of the mastjhas nonlinear character.

In this case (see Fig.7) mast 73 has an "underwater" continuation: axis 74 by bearings 75, 76, to which is added the Schwerte 77. Additional Schwerte 77 is rigidly connected with the console 78 reading finger 79 spatial functional Cam 80. The mast 73 rigidly fastened to the axle of steps 81 mounted in bearings 82, 83, mounted in the lower part Sortavala well the hull of a sailing Board.

In Fig. 8 shows the sailboard, the housing 84 is installed in the axis of steps 85 in bearings 86, 87. Mast 88 sailing Board mounted in a cardan joint, which includes: the axis of steps with bearings, respectively, 85, 86, 87 for sakranvina mast 88 on the right or left side of the hull of a sailing Board, hinge 89, providing the evolution of the mast 88 diametrically x rotating mast 88 about the axis of symmetry (Fig.8). In Fig.8 is conventionally shown two positions of the mast I and II, which cause additional barriers Schwerte 93 mounted on an axis on bearings 94 95, 96, on the cornerj. As a reader the finger 97 is entered in the spatial Cam 98 fixed to the housing 84, any rotation of the mast 88 at any anglejcauses a change in angle of attackiadditional Schwerte 93. Depending on the profile of the groove of the spatial Cam 98 will be implemented in particular the dependence of (). In the General case is non-linear. If this is the requirement of similarity of the control algorithms on the proposed "Way..." and traditional: yachtsman just manages sail rigging and sailing Board, and the driver of the hydrodynamic lifting force takes yachtsman most of the overhead associated with maintaining the mast in position on the roll. In Fig. 8 POS. 63 indicated Schwerte, designed to compensate for drift sailing Board when sailing. Additional Schwerte 93 (Fig.8) may be provided with a mechanism for cleaning additional Schwerte (Fig. 8 - not shown), for example, performed by analogy with a hinged or swivel retractable svertui (see, for example, Fig.45 page 74 [C3]) Parwanoo shaper D. P.F.

(Fig.9) contains a bevel gear 99, the hub of which is rigidly connected with additional Schwerte 100 symmetric cross-section, mounted on bearings 101, 102 on the axis 103, which is the "continuation of mast 104, rigidly fastened to the axle of steps 105 mounted in bearings 106, 107, mounted in the lower part Sortavala well (for the circuit of Fig.9 - not shown); (axle gears 99 coincides with the axis 103). Gear 99 is entered in engagement with the bevel gear wheel 108 firmly attached to the hull of the sailing Board. When zakryvanii mast 104 around steps axis 105 by an anglej, bevel gear 99 will be in our teams on the wheel 108 and, as a consequence, additional Schwerte 100 will be deployed at the appropriate angle of attacki. In this case, = (K), angle of attacktwill linearly depend on the roll angle of the mastj.

Let us dwell in more detail on another kinematic scheme, dynamic shaper with a linear dependence (K) angle of attack angle of sakranvina mast of a sailing vessel (Fig.10).

Here the axis (shaft) of steps 109 fixed in bearings 110, 111, mounted on the hull of the sailing Board at an angle to the horizontal plane. On the axis (shaft) of steps 109 rigidly sadoski provided the tilt of the mast 113 on the right and left side of the sailing Board on the cornerjcauses a rotation axis (shaft) of steps 109 to the appropriate anglejand a turn angle jadditional Schwerte 114. It is obvious (see Fig.10) that rotate about an axis (shaft) 109 additional Schwerte 114 causes the angle of attacki. The dependence of the angle of attack of additional Schwerte 114 from the angle of the mast 113:

(7)

where is the angle of inclination of an axis (shaft) of steps 109 relative to the horizontal plane.

It can be shown that the dependence of () is expressed by the formula (8):

= arcsin(sinsin) (8)

With sufficient practical accuracy of the formula (8) can be represented by a family of lines (see Fig.11). Thus the kinematic diagram in Fig.10 allows you to get the driver compensates hydrodynamic lifting force on additional Schwerte with linear characteristic (Fig.11). The linearity of growth allows the sailor to adapt quickly to the management of the sailing Board, equipped with a shaper, D. p. C. Consider ways of practical realization of the device according to the kinematic diagram of Fig.10. Analysis of the kinematic scheme allows you to convert the diagram (Fig.10), in which instead of the axis of steps 109 (Fig.10) poyavliaetsia plane. In the upper part of the shaft of steps 115 rigidly fixed hinge 118 with fittings for attaching the mast 119 with a sail 120. In the lower part of the shaft of steps 115 rigidly fixed additional Schwerte 121. Obviously, zakryvanii mast 119 on the cornerjcauses additional rotation of Schwerte 121 at the appropriate angle and, as a consequence, the emergence of a non-zero angle of attack additional Schwertei.

In Fig.12 POS.63 indicated Schwerte, designed to compensate for drift sailing Board 117 when sailing. Detail design of Fig.12 allows us to imagine two options for the layout of Fig.13 and 14.

In Fig. 13 Schwerte 63 fixedly mounted under the bottom of the sailing Board. Additional Schwerte 122 mounted on the shaft of steps 123 installed at an angletoto the horizontal plane in the stern tube 124. On the upper part of the shaft steps 123 has a flange additional Schwerte 125 rigidly fastened to the shaft (axis) 123. The flange 125 is supplied by a lead 126, which can be deployed to the kinematic closure with the flange 127 or with a fixed flange 128. Kinematic circuit is provided through special grooves 129, 130 on the flanges 127 and 123 of Fig.13, 15. In this case, using a powered coupling obileni it a fixture for mounting a mast 131 (Fig.13) with sail rigging of the sailing Board. It is enough leash 126 to enter into the groove 129 on the housing flange 127. At the same time, the translation of a lead 126 in one of the grooves 130, 132, 133 (Fig.16) on the fixed flange 128 will result in the fixation of the lead 126 one of the latches 135, 136, 137 (Fig.16) and will record additional Schwerte in one of the following positions: vertical, horizontal, or in one of the intermediate positions on the choice of the yachtsman. Rigidly mounted on the shaft of steps 123 flange 134 provides certainty chopper in the axial direction of the flange 127 on the shaft of steps 123.

An obvious disadvantage of the design of Fig.13 (Schwerte 63 fixed structures), complicating its operation, can be overcome in the construction shown in Fig.14. Here in the stern tube 138 at an angle to the horizontal plane is equipped with two coaxial shaft: shaft 139 additional Schwerte 140 and the shaft 141 of Schwerte 63. Using a powered coupling with flanges 125, 127, 128 may connect additional Schwerte 140, via a shaft 139 is rigidly secured on the flange 142 with a lead 143 to the flange 144, supplied with fittings for fastening the mast 145. The Schwerte 63 by means of shaft 141 with the flange 146 and through lead 147 may be fixed relative to the fixed flange 148 in one of the operating positions: om a leash (flange 148 is rigidly fixed in the housing sailing Board 149). Translation of a lead 143 to the left until it engages one of the grooves on the fixed flange 150 additional Schwerte 140 may be disconnected from the flange 144 with its fittings for fastening rigged and fixed in one of the operating positions: transport, to compensate for the "planning" on Schwerte, etc.

The flange 144 on the shaft 139 (Fig.14) is equipped cardamomum hinge (Fig.17) with the axis 151 of the swing mast 152 in DP the hull of a sailing vessel and the axis 153, around which the mast 152 can be deployed in any direction 360o. Zakryvanii mast 152 can be carried out around the shaft (axis) 139 (Fig.14).

Constructive design additional 140 and protivogribkovogo 63 Vertov shown in Fig.14, allows the adjustment of sailing rig sailing boards to different driving modes: when the strong and weak winds, to operate a sailing Board in shallow water and at great depths.

Device for ensuring the sustainability of the mast of a sailing vessel with driver hydrodynamic lifting force variable type (see scheme 1 Fig. 3) involves the implementation dependencies:

(9)

where is the roll angle of the mast relative to the hull of a sailing Board,

is a parameter value which is selected by the trigger the STV direct (Fig. 11) with index I, II, III. This refers to that between the shaft of steps mounted on the body of the sail Board with fittings for attachment of the mast, and the shaft of additional Schwerte include the gearbox, which allows for a constant angleconsttilt shaft additional Schwerte due to the change gear ratio "to achieve" changes according to (), that is (,).

Immediately let's keep in mind that a sailor should make your choice I, II or III speed switching governing body... legs. To this end, the deck 154 sailing Board 155 (Fig.18) must be provided by the pedal switch 156 "speed" - gear ratios and reverse. Taking into account the objectives set for the switching speed yachtsman presses his foot on the pedal 156 (Fig.18, 19) with simultaneous removal of the mast 157 in the median plane of the hull of a sailing Board 155 (Fig.18, POS.158 Fig.19) and thus provides "triggered" synchronizer 159 (Fig.20) gearbox (gears Z1, Z2,.., Z10, Z11, Z12). Under "synchronization" in our case it is necessary to understand the simultaneous removal of the mast 157 and additional Schwerte 164 (Fig.21) in the vertical position. Then hold the pedal 15 is arelocated speeds 165 kinematically compatible with the drive gears 166 Z8, Z9, Z10the sailor takes a leg "to the left" or "right", depending on the selected speed - ratio gearbox. As mentioned above, switching the gearbox changes gear ratio between the shaft of steps 167 (Fig.19) and shaft (Fig.21) additional Schwerte 164. Here we note the possibility of reverse due to the replacement of, for example, gear Z2the gear train Z11, Z12.

Given mnogolikost work sailboard with extra powered clutch with foot switch. In Fig.18 shows the flange 169, 172 and pedal 171, clicking on which foot, yachtsman outputs from engagement with the flange 169 (Fig.21) pin 170 foot key 171 and forth movement of the legs in the plane perpendicular to the median plane of the hull of a sailing Board, rotate the flange 172 on the 90oto align the pin 173 foot keys 171 with one of the holes 174, 175 (Fig.23) of the latch 176 the provisions of the additional Schwerte 164. In this case, the following happens:

1. displays "subjection" broken connection between the shaft 167 (Fig.19) and shaft 168 (Fig.21) additional Schwerte 164;

2. additional Schwerte 164 is fixed in one of the horizontal positions, the shaft 178 is kinematically connects the shaft 168 additional Schwerte 164 (Fig.21) with gearbox and shaft steps 167 (Fig.19). In Fig.22, 23 shown fragments of the flanges powered clutch. When provided with additional holes for fixation of the pin flange 173 176 will allow you to capture additional Schwerte 164 in intermediate positions that can be used when swimming at full courses with the main Schwerte" 179 (Fig.19).

Note that using the "P"-shaped in plan configuration of the gear box 180 (Fig.18), can be conveniently placed protivogradovye the Schwerte 179 (Fig.19) on the housing sailing Board 154 (Fig.18 see POS.181 - svartby well and Schwerte 173).

Proposed technical solution: "Method and device for its implementation. . ..", allows you to optimize the Aero-hydrobiologia sailing ship and, consequently, to increase propulsion, maneuverability, payload capacity and usability of the sailing vessel.

1. The only way to ensure stability of the mast of a sailing vessel in position on the roll by forming forces that hold the mast in position in the plane perpendicular to the median plane of the hull of a sailing vessel, characterized in that the forming torque of the hydraulic lifting force, the magnitude and direction of which is fully or partially provide working on is about the ship in position on the roll, containing steps with a fixed mast with a sail-aerogram with variable geometry, characterized in that steps supply axis (shaft) bearings, and the mast provide additional underwater part with additional Schwerte-hydrocream with variable geometry, the axis (shaft) of steps rigidly fastened to the mast of a sailing ship in between the aerial and gidroksilnami and provides a low resistance rotation, zakryvanii mast on the left and right side of the hull of a sailing vessel.
