Description

The invention relates to transport equipment, in particular to small shipbuilding, and can be used in the design of planing hulls.

A similar hull of a vessel [1] with sharp-cut contours is known, having a keel bottom and transom stern, and on the bottom of the hull in the area of the midship and stern there are respectively a midship and stern trim, the lower keeled surface of each of which forms an acute angle with the bottom of the hull along movement, and the width of the trim is less than the width of the hull, measured between sharp cheekbones, and the width of the midsection is less than the width of the feed trim.

The disadvantage of the analogue is the lack of functionality and low manufacturability due to the complexity of the contours.

The hull of a planing vessel [2] was selected as a prototype, containing a board, bow with bow, a transom and a bottom located between them and equipped with a central horizontally located hydro-ski, the lateral edges of which are formed by longitudinal redana-splash guards, as well as two side sponsons, while the inner lateral surfaces of the latter, mating with the surface of the bottom and the lateral faces of the hydro-ski, form two longitudinal tunnels, and the casing contains front transverse redans and rear transverse sagittal Redans, additional spray skis, separated from the tunnels by the front transverse redans, while the tunnels and sponsons form trimaran contours in 1/3 of the front of the hull, passing through the front transverse skirts to the spray skis, which are separated by a rear transverse arrow-shaped redans in 1 / 5 along the length of the hull from the stern, and the hydro-ski is made with inclined side surfaces adjacent to it, and spray chippers are made on board.

The disadvantage of the prototype is the lack of functionality and low adaptability, due to the complexity of the contours.

The technical result of the present invention is to expand the functionality of the hull and increase the manufacturability of its manufacture.

The technical result is achieved by the fact that the hull of a small vessel contains a board, a bow, a transom and a bottom located between them and equipped with a central horizontal hydro-ski located below the main plane of the bottom, formed by longitudinal redans-spray bumpers and paired with them vertical or inclined side faces, with this surface of the ski has a bevel in the area of conjugation with the transom to the height of the longitudinal redans and is flat along the rest of its length with the possibility of installing wear-resistant of overlays, and the planes of hydro-skis and spray chutes are parallel or the spray chambers have wakefulness.

The claimed device is shown in FIG. 1 is a side view and from the stern of the hull of a small vessel, FIG. 2 - general view of the housing.

The device comprises a bow 1, transom 2. Combined contours of the hull of a small vessel are a hydro-ski 3 with aft bevel 4, passing from the transom to the end of the bow with inclined or vertical side faces 5 of the bottom, longitudinal redans, mudguards 6 and sides 7. B cross section the width of the ski 3 does not exceed 1/3 of the width of the body.

The wetted surface of the ski 3 has a projection of a rectangle elongated along the body. It is chosen so that at full speed the vessel glides on it, as on a plate, and the inclined lateral faces of the bottom 5 and longitudinal redana-spray bumps 6 are wetted only during roll, meeting the wave, or in a displacement mode. Hydro ski 3 is made flat along its length, which is at least 1/2 of the length of the hull. The rest of the hydro-ski can be flat or have a slight variable wake. The surface of the hydro-ski has a bevel in the area of conjugation with the transom to the height of the longitudinal redans and is flat along the rest of its length with the possibility of installing wear-resistant linings, and the planes of the hydro-ski and spray chutes are parallel or the spray chutes are keeled.

The form of conjugation of the side faces of the bottom 5 and the longitudinal redans-spray chutes 6 involves cutting off a spray sheet from them when the body enters the wave.

Wide spray-bumpers 6, forming two skis (each of which does not exceed 1/3 of the total width of the bottom), which serve as additional gliding surfaces at the moment of reaching the design mode of movement, reducing hydraulic resistance, and are designed to reduce the wetted surface of the hull of a small vessel when swimming on a wave.

Redana-spray chutes 6, which creates additional lifting force, are located along the entire length of the housing. In addition to the fact that they contribute to the creation of lifting force, reflect the spray escaping from under the hydro-ski 3, and give the vessel high stability, contribute to increasing the stability of the vessel, dampen side and longitudinal pitching, and soften the shock loads of the boat on the wave.

The hull of a small vessel is operated as follows.

The hull of the planing vessel has combined contours, including elements of several classic contours. The combination of these contours in one housing with predetermined relationships depending on the operating mode allows you to get a number of new more effective running characteristics of the body in different operating modes: parking, low speed, transition mode, planing.

In addition to better stability and seaworthiness, when parked on a lateral wave, the hull of a small boat provides better stability due to the presence of splash guards 6.

At low speeds, the vessel glides over the full width of the bottom with a reduced specific load, which is optimal for a given speed. As the acceleration increases, the hydrodynamic lifting force grows; the case during the transition mode reduces the draft. In this case, the sides 7 come out of the water, the planing surface is limited to a pair of redans-spray chutes 6 and hydro-skiing 3. Thanks to the combination of hydro-skis 3 and redans-spray chutes 6, the width of the bottom is automatically adjusted depending on the speed of the vessel.

On the move, with a sharp roll on the roll-splint 6 of the heeled side, an additional lifting force arises, which prevents a further increase in the heel, water overflow and capsizing of the vessel.

In the transition to gliding mode, the bottom resistance of the hull of a small vessel is lower than that of other gliding hulls, including those with flat and pitching contours due to the use of aft slope of a hydro-ski 4, therefore the hull of a small vessel goes faster to planing and develops a higher speed at full load.

As a result, the hull of a small boat with hydro-ski 3, equipped with a sufficiently powerful engine, is capable of developing greater speed, and also has greater gliding stability and less sensitivity to changes in trim and the position of the center of gravity.

In addition to better stability and seaworthiness on the wave, the hull of a small vessel provides more opportunities for planning the internal location due to the bow shape that is rectangular in terms of shape and increased load capacity by 30% at the same dimensions.

The small longitudinal swing, support of small trim and the absence of delphining when gliding at high speeds, achieved through the combination of hydro-ski 3 and redana-splash guards 6, eliminates the need to use transom plates in various operating modes due to the optimization of body contours.

A significant expansion of the capabilities of the hull of a small vessel is achieved due to the significantly increased strength of the lower part of the bottom, formed by hydro-ski 3 and the inclined or vertical side faces of the bottom 5 with a record low weight of the structure as a whole. Subject to the use of wear-resistant linings for hydro-skiing, the hull of a small boat can be used at shallow depths with both a conventional and rocky bottom (in combination with a jet propulsion), and also as a trailer - a sled behind a snowmobile.

When driving in deep snow, the shape of the hull of a small boat has much less resistance and a tendency to tip over compared to sledges of similar sizes due to the fact that the lower part of the bottom, formed by hydro-ski 3 and sections of the bottom 5, moves in a track formed by a snowmobile with an average depth of 130 up to 250 mm, and wide redana-splash bumpers 6 perform a stabilizing function when a roll occurs.

When moving on rolled surfaces in winter to increase stability, it is possible to use removable skis attached to the sides of the hull.

The invention is aimed at reducing the cost of the final consumer, resulting in a multi-functional hull of a small vessel, which will independently organize comfortable safe outdoor activities in various climatic zones both on the territory of RUSSIA and beyond.

Example. They made the hull of the vessel with the given dimensions obtained as a result of the calculations. The tests performed showed the following:

- increased by 30%, compared with vessels of similar dimensions, the carrying capacity of the vessel;

- the speed of access to planing has increased by 50% compared with similar keelboats;

- increased stability of the vessel compared to similar flat-bottomed vessels;

- the vessel can be used as a sled trailer for transporting goods up to 700 kg on virgin snow, and on a packed road, provided that the supporting skis are installed;

- the mass of the hull relative to the hull-shaped hulls has decreased to the level of flat-bottomed hulls.

The manufacturing process of the vessel confirmed the high manufacturability achieved by the lack of sophisticated piece surfaces.
