Models of paddle steamers drawings. Rubber model of a paddle steamer. Drawing, description. Description of the steamship “Bohemia”

Running model of a paddle steamer. The model of a river paddle steamer looks just as advantageous compared to the model of a modern passenger airliner, how much more attractive is a large-scale replica of a steam locomotive than a replica of a railway locomotive today. And on the water, the running model of the “wheel-drive” of the 19th century looks simply amazing - the abundance of superstructures, masts, pipes, practical things - all this creates an indescribable flavor of the age of steam.

We present to the attention of ship modelers a model of the paddle steamer "BURLAK" - similar cargo and passenger ships in late XIX centuries were widespread on the rivers of Siberia. The length of this steamship was 48 m, width - 8.25 m and draft with a full load - 1.25 m. Paddle wheels, driven by a 120 hp steam engine, provided the ship with a speed of about 10 versts per hour.

The ship's hull was constructed from rectangular frames with rounded cheekbones. At the rear of the body there was a steering wheel, consisting of a wooden feather mounted in a forged steel frame. The feather was attached to the crinoline with a chain sorlin.

A manual anchor-mooring capstan was installed in the bow of the vessel, which was used to remove the collar (anchor chain) and mooring ropes. Admiralty type anchors with steel rods were attached to the steamer in a traveling manner - on fish beams with hoists and hooks. There, in front of the spire, a bollard was fixed, intended for towing the vessel. Mooring bollards were located two on each side - in the bow and stern of the vessel.

1 - electric motor MU-30; 2 - gearbox fastening (M5 bolt with nut); 3 - gearbox housing (duralumin, sheet s4); 4 - fastening the gearbox cover (M5 bolt with nut); 5 - primary gear of the gearbox; 6 - first stage gear; 7 - second stage gear; 8 - intermediate shaft; 9.17 - bushings-bearings of the intermediate shaft (bronze); 10 - gearbox cover (duralumin, sheet s4); 11.16 - propeller shaft bearing bushings (bronze); 12 - propeller shaft (steel); 13,15 - spacer bushings (steel); 14 - second stage gear

The steamship was propelled by paddle wheels, partially submerged in water. Each wheel consisted of a hub, rings and spokes - eight wooden tiles were fixed between the latter. At deck level, the paddle wheels were edged with skirts; On top of the wheels were covered with side metal casings. Open navigation bridges were installed on top of the casings. Service premises were also built on the outskirts.

In the central part of the ship, between the paddle wheels, there was an engine room, and behind it was a boiler casing.

Passenger cabins of the first and second classes were located on the deck. At the front of the ship, above the cabins, there was a promenade deck; benches were installed along the railing - three on each side. There were two ladders to access the promenade deck. The wheelhouse was located in the central part of the vessel.

Behind the aft cabins there was a tiller drive compartment, closed on top with a wooden lattice; The drive lines were routed into the wheelhouse along boxes along the starboard and port sides.

Making a model of the Burlak steamship is not too difficult. The recommended scale is 1:50, while the length of the “wheel” will be 960 mm - this will be quite enough for both a running model (with or without radio control) and a bench model.

Almost all parts of the hull and superstructures can be made from birch plywood with a thickness of 3 to 5 mm. The paddle wheel discs are also cut from 3mm plywood, the tiles are cut from beech slats, and the hubs are turned from birch. All plywood elements are assembled using epoxy glue; after its polymerization and cleaning, the prepared assembly units are coated with parquet varnish.

A deck is glued into the finished hull, made integrally with plywood trims 4 mm thick. The deck must have cutouts for superstructures (through which access to the model's power plant and radio equipment is provided), as well as for paddle wheels. The protective covers of the paddle wheels are cut from sheet aluminum 0.5 mm thick.

On the deck of the model, bow and stern mooring bollards, an anchor device, and an anchor-mooring capstan are fixed. A chimney is installed behind the wheelhouse - its body is best soldered from 0.3 mm thick tinplate. The bases of the ventilation deflectors can be made from the same material, and the air intakes for them can be made from plastic balls from children's toys of suitable diameter.

Separate elements of the steamship model

The power plant of the ship model is based on the MU-30 electric motor (its operating voltage is 27 V, current consumption is 5 A, power is 40 W, rotation speed is 7500 rpm). To drive the paddle wheels, a homemade two-stage gearbox with a gear ratio of about 20 is used, which ensures a paddle wheel rotation speed of 375 rpm.

Of course, it is difficult to make gear wheels yourself in a home workshop, so the design of the gearbox will have to start with the selection of two cylindrical gear pairs with a module of 1.5 - 2 mm and with gear ratios 4 and 5. The gear housing parts are cut from sheet duralumin, the shafts are steel, turned, gears and gears are pressed onto them and secured with 1 mm pins, which provides reliable protection against rotation. Bronze bushings pressed into the base and cover of the housing are used as sliding bearings.

Recommended color of the steamship model: the hull below the waterline, rudder blade and paddle wheels are red; the side above the waterline, bulwarks, bollards, capstan, anchor chains, anchors, ventilation deflectors and fenders are black; mast, superstructures, paddle wheel casings above the bulwarks, fish beams, wheelhouse, name of the ship, lifebuoys, railings, awning, vestibule, racks, shelving and fire buckets, as well as benches - white; ladders, decks, side superstructure floors, paddle wheel casings and fenders - light gray; doors, frames of rectangular portholes of superstructures and deckhouses are made of natural wood.

A navigator lives in the soul of every boy, so any stream of rain is already a river, and a large puddle is a whole sea, calling to launch boats - from the simplest, from a chip or a sheet of paper, to specially planed ones, and even more so combined ones, like those proposed by a German magazine " Technium" self-propelled model of a steamship. Yes, not an ordinary steamship, but an old one, two-pipe, with paddle wheels on the sides. What child wouldn’t want to build one, especially since its design is quite accessible for independent reproduction.

Indeed, all the parts are so simple that they can be made and assembled in one evening. Judge for yourself. The model essentially consists of two large parts: a hull with a propulsion unit and a deck superstructure. Let’s take a closer look at what components they are divided into.

Frame

It is a flat board with a streamlined shape. The front end has a traditional point for ships and boats, which reduces water resistance when moving forward, and the aft part of the hull is simply cut off in the transverse direction. A tin rudder is installed here. The easiest way to attach it is by cutting it into a pre-made slot in the stern. By bending or bending it, you can send the boat in a circle or change direction.

There are two nails driven into the front and rear parts of the hull: these are support pins; the deck is installed on them. There are wide cutouts on the sides of the body for the blade mover.

Mover

It is installed on two flat sheet metal brackets attached in the cutouts. The propulsion unit consists of two wheels with blades and an axle. The wheel hubs are two wooden rounds (or plugs), along the circumference of which slots are cut for tin blades. The wheels are protected by tin arches attached to cutouts in the body.

A - deck pattern

To drive the wheels into rotation, a rubber motor is mounted on the body. For it, pulleys (rollers) are installed along the center line of the body in its front and rear parts, through which a thin elastic band is pulled. One end of it is attached to the front part of the body, and the second - to the axis of the blade propulsion. By rotating the latter, the rubber band is wound around its axis: this is how the rubber motor starts. If you now let go of the wheel, the elastic band will begin to unwind, causing the wheel with blades to rotate through the axis.

Deck

It is hollow to cover all the protruding parts of the body. Cut out of tin. Figure 1 shows the pattern of the deck: the shaded areas of the cut blank are folded back - the bow and stern parts of the deck are formed from them.

The deck superstructure itself is installed in the places marked with dotted lines on the pattern. It can also be made of tin; but it’s easier to assemble it from wooden elements: a flat plank platform, a cabin-house and two pipes (really from pipes or sections of a round wooden rod). Foam plastic may be suitable as an affordable and convenient material for superstructure elements. Any pencil can serve as a mast, and harsh black threads can serve as guy ropes.

The deck is installed on the body pins intended for it and is additionally supported by its cutouts on the sides on the axis of the blade mover.

Coloring

The wooden blank of the model body is best protected from getting wet by oil paint. It can be applied with a brush in two layers: the first is the most liquid, for better saturation of the wood surface, and the second is of normal consistency, of any color: after all, the hull is practically invisible from under the deck shell.

To paint the remaining elements of the model, it is convenient to use aerosol cans, and the paint can be different: the boat will turn out more elegant, more beautiful. Aerosol coating is easier to apply and adheres better to any material - both metal and wood, forming a thin, light paint layer that is not burdensome for a small model.

Each element of the model can be painted separately as it is being manufactured, that is, even before assembly. However, if it is decided to finally paint the model after assembly with one color, the preliminary element-by-element coating of the parts can be omitted and an aerosol can can be used on the finished model.

Starting the model

Preparation for launching the boat comes down mainly to tightening the rubber motor. To do this, it is not necessary to raise the deck: access to the rubber motor is provided from the outside, through the blade mover. It is enough to take the model in left hand, and insert the right index finger between the propeller blades and rotate it. You need to twist the propulsion unit in any position of the boat in your hand from its bow - then the rubber motor will spin the blades in the right direction.

The hull of this steamship model is a flat plank with a streamlined shape. The front end has a traditional point for ships and boats, which reduces water resistance when moving forward, and the aft part of the hull is simply cut off in the transverse direction. A tin rudder is installed here.

The easiest way to attach it is by cutting it into a pre-made slot in the stern. By bending or bending it, you can send the boat in a circle or change direction. There are two nails driven into the front and rear parts of the hull: these are support pins; the deck is installed on them. There are wide cutouts made on the sides of the steamer's hull for the blade propulsion.

Propulsion model of a paddle steamer

It is installed on two flat sheet metal brackets attached to the cutouts. The propulsion unit consists of two wheels with blades and an axle. The wheel hubs are two wooden rounds (or plugs), along the circumference of which slots are cut for tin blades. The wheels are protected by tin arches attached to the cutouts of the body.

By rotating the latter, the rubber band is wound around its axis: this is how the rubber motor starts. If you now let go of the wheel, the elastic band will begin to unwind, causing the wheel with blades to rotate through the axle.

Deck of a paddle steamer model

It is hollow to cover all the protruding parts of the body. Cut out of tin. Figure 1 shows a pattern for a steamship deck: the shaded areas of the cut blank are folded back to form the bow and stern parts of the deck.

The deck superstructure itself is installed in the places marked with dotted lines on the pattern. It can also be made of tin; but it’s easier to assemble it from wooden elements: a flat plank platform, a cabin house and two pipes (really from pipes or sections of a round wooden rod). Foam plastic may be suitable as an affordable and convenient material for superstructure elements.

Any pencil can serve as a mast for this steamer, and harsh black threads can serve as guy ropes. The deck is installed on the housing pins intended for it and is additionally supported by its cutouts on the sides on the axis of the blade propulsion.

Painting a paddle steamer model

To paint the remaining elements of the steamship model, it is convenient to use aerosol cans, and the paint can be different: the ship will turn out more elegant, more beautiful. Aerosol coating is easier to apply and adheres better to any material - both metal and wood, forming a thin, light paint layer that is not burdensome for a small model.

Launch of a paddle steamer model

You need to spin the propulsion unit in any position of the boat in your hand from its bow - then the rubber motor will spin the blades in the right direction. Then, holding the propeller blades with your left hand, lower the model onto the water so that they are submerged in the water: you can, by adjusting the steering wheel to the desired course, release the boat on its first voyage. Its range will depend on the degree of twist of the rubber motor.

Czech magazine "ABC"

The topic brought to the attention of ship modellers today, it seems, will be of interest to copyists of various levels, from schoolchildren building contour rubber-engined “straightforward” ships, to experienced sportsmen-radio operators. The fact is that we offer a steamship with paddle wheels for reproduction in miniature - model shipbuilders do not need to be told in detail about the “delicacy” of such work.
One of the most elegant river steamships of the last century, the Czech-built Bohemia, created in 1841, was chosen as a prototype for copying. Along with effectiveness appearance This ship is also characterized by comparative simplicity, which by no means comes to the detriment of the copy version of the model.

A copy of “Bohemia” can be made not only for use in various sports classes, but also in different designs. For example, a fairly large elongation hull with different contours of the bow, central and stern parts is well reproduced both in the classic version with frames and plating made of precisely fitted linden or balsa slats, and in the shell version, made of fiberglass on a blank. It would not be a sin to remember such an option as making an entire body from a single block of wood, followed by hollowing it out until a wall thickness of 2-3 mm is obtained, followed by installing sparsely spaced frames. Despite the exaggeration of such technology, which is more typical for school ship models, when copying the “Bohemia” with its wide, low hull, such a technique is quite justified, even in the case of creating a high-quality model.
Having determined the copying scale, it is necessary to draw the main projections of the model in full size and arrange the “filling” of the body. To help those who are thinking about making a similar micro-steamer, we present the layout of the most complex option - a model with a length of only 720 mm, with radio control. As can be seen in the figures, even with such small dimensions, all nodes are placed in the case quite freely, so when creating a larger copy, there should be no problems at all.
At this scale, it is easiest to make the deck entirely removable by gluing a blank for it from individual pine or linden slats with a cross-section of 2x4 mm. The model's drive - from a conventional unboosted electric motor with a voltage of 3-4.5 V - is quite sufficient in power for large-scale travel speeds. Unlike the prototype, it is better to place the gear reducer inside the housing. It should have a gear ratio of about 1:10. The single shaft of the paddle wheels is made of steel wire with a diameter of 4 mm and on the copy passes through two bronze bearings installed in the side bosses directly below the deck.
The materials for making the paddle wheels themselves can be very different. Let's name only two main options: all-wood, using plywood “rims”, slats and plates, and all-metal. In the latter case, in addition to steel or brass wire, you will need to find suitable sheet blanks for rowing plates. In the same way, different designs are acceptable when working on the steering wheel and its drive.
Superstructures and all components located on the deck are best mounted tightly. The main material for volumetric superstructures must be celluloid, although “boxes” made of plywood, textolite or even cardboard will turn out not much worse (the latter will have to be soaked through with warm drying oil). Fences and awning posts are made of wire and assembled by soldering. For small parts, the easiest work and best appearance will be ensured by using solid wood. The final external effect will depend on the quality of finishing, varnishing and painting. The body in the hollowed-out version is impregnated with drying oil or liquid two-component parquet varnish, after which it is painted.
The driving performance of the miniature “Bohemia” is very good. True, it must be admitted that for such a copy it is still better to have a water surface with a small wave. After the start, the model quickly accelerates and, despite the large elongation of the body, responds quite “briskly” to steering wheel deviations. At the specified copying scale, the weight of a fully equipped model should be in the range of 1000-1100g.

DESCRIPTION OF THE STEAM SHIP “BOHEMIA”

The ship's hull is divided by bulkheads into the following compartments (starting from the bow): open bow compartment 5.35 m long, galley - 1.5 m, second class saloon - 6.3 m, crew cabins and storage rooms - 3.3 m, engine room compartment and boiler room - 5.85 m, crew cabins - 1.5 m, ladies' room (cabin) - 3.6 m, first class passenger cabin - about 10.6 m. Toilets were located in superstructures located directly in front of the paddle wheel housings . The deck was used for passengers to walk around; if necessary, benches were installed on it. The rear part of the deck could be covered with a canvas awning stretched over the side posts.
The steamship's hull, superstructure and paddle wheel casings are made of wood: only the side and bottom frames were made from iron corner profiles. As can be seen from the above figures, “Bohemia” had an unusually elongated hull with an almost rectangular cross-section in its central part and rounded contours in the bow and stern. The complete displacement coefficient is 0.65. The front part of the keel curved elegantly upward, forming at the end a base for mounting the figurehead - a silver-painted Bohemian lion with a gold royal crown on its head. The total length of the bow figure was approximately 0.9 m. The aft part of the hull was steep. She carried a 1.6 m long rudder plate suspended on three hinges.
“Bohemia” was equipped with a two-cylinder steam engine with oscillating-type cylinders, vertically arranged. The diameter of the cylinders was 0.525 m and the stroke was 0.725 m. At 40 rpm, the engine developed a power of 37.5 kW (51 hp). The steam engine was supplied a steam condenser and a stroke reversal system. It was made in England and was very advanced for its time. It is interesting that this machine was after “Bohemia”. long time served on another ship, and there are assumptions that she works to this day on the ship “Dizbar”.
The steam boiler was manufactured by the same company that built the steam engine. The operating steam pressure is 1.33 atm. Inside the boiler with three fireboxes with a combustion area of about 35 m2, 165 copper tubes with a diameter of 54 mm, connected in three bundles, were placed. The fuel combustion products passed between these tubes, heated the water and were released into the atmosphere through a chimney about 4.5 m high. The design of the pipe was an assembly of five sections, and between the second and third there was a connector that allowed the upper part to be tilted (folded) when passing under low bridges. The system for lowering and raising the pipe is a pulley system, using blocks and ropes leading to a folding mast.
The steam engine rotated the side paddle wheels through a gear transmission with a gear ratio of 1:1.5, and the drive gears were located outside the housing in the volumes of the paddle wheel casings. The iron rims of the paddle wheels had an outer diameter of about 4.1 m and the lower edge was equal to the level of the bottom point of the hull bottom. 12 propeller blades on each wheel were screwed to the metal spokes; their size was 0.35 x 1.6 m. The casing with an outer diameter of 2.15 m and a width of 1.95 m had waterproof walls, except for the outer ones, which were wooden gratings.
The wooden steering wheel was operated by cables running from the steering wheel through a pulley system. On the axis of the wheel, the diameter of which was 1.5 m, there was a drive drum with a cable. A special platform was equipped for the helmsman, which allowed him to have a forward view of the water area.
The Admiralty type anchor, about 1.2 m long, was raised manually and, in the stowed position, lay freely on the starboard side of the front part of the hull.
To carry the flag and place the mechanism for folding the chimney, a large mast 9 m high was installed in the front part of the steamer. It also folded back, for which two cables running from the mast forward and to the left side served. To carry the stern flag, a rigid flagpole with a height of 3.3 m was installed at the rear of the hull.
The rear passenger compartment (first class) was illuminated by five portholes on each side, the front (second class) by two pairs of portholes. Each of them was a three-section opening with glass with a total size of 0.6x1.8 m. Two windows were located on the front wall of the building to brighten the galley; skylights were installed above the engine room and crew quarters. The captain's bridge with rigid handrails was mounted between the casings of the paddle wheels - a ladder led to it from the deck. Ahead of the deck was a conductor's bench, in front of which a bell was suspended on a curved bracket. There, nearby, there was a chimney from the galley and a steam exhaust pipe from the boiler safety valve.
The side plating of the hull was protected by four overhead strips. The lowest one was located almost above the waterline; the next one ran along the lower edge of the portholes, and along their upper edge was another bar. The fourth and last one walked along the edge of the deck.
During passages through Czech territory, a red flag with narrow white horizontal edges and a silver Czech lion in the middle was raised on the stern flagpole. On the territory of Hungary, the flag was replaced by a red-white-red one with the image of a shield. The mast carried a long white-red-white pennant with the name of the ship in white inscription. On the inner walls of the paddle wheel casings there was a small Hungarian emblem (a double-headed eagle with a shield).
The bottom of the hull and the lower part of the port, including the lower trim strips, were dark brown. The strip between the portholes, porthole frames, entrance deck railings, paddle wheel casings (excluding grilles), overhangs, fences, mast, flagpole, and skylight housings were painted white. Red: top three rows of trim strips and paddle wheels. The anchor, the upper casing of the steam boiler above deck, all the chimneys and parts of the frames visible in the open forward part of the hull were black. The deck, captain's bridge, conductor's bench, steering mechanism with bridge and rudder blade had the color of natural wood impregnated with linseed oil. The paddle wheel grilles and stripes at the top and bottom of the portholes were painted dark green.

We offer to the attention of ship modellers paddle steamer model"BURLAK" - similar cargo and passenger ships at the end of the 19th century were widespread on the rivers of Siberia. The length of this steamship was 48 m, beam - 8.25 m and draft with full load - 1.25 m.

Rowing wheels, driven by a steam engine with a power of 120 hp, provided the steamship with a speed of about 10 versts per hour. The ship's hull was constructed from rectangular frames with rounded cheekbones. At the rear of the body there was a steering wheel, consisting of a wooden feather mounted in a forged steel frame. The feather was attached to the crinoline with a chain sorlin.

A manual anchor-mooring capstan was installed in the bow of the vessel, which was used to remove the collar (anchor chain) and mooring ropes. Admiralty type anchors with steel rods were attached to steamship in a marching manner - on fish beams with hoists and hooks. There, in front of the spire, a bollard was fixed, intended for towing the vessel. Mooring bollards were located two on each side - in the bow and stern of the vessel.

The steamship was propelled by rowing wheels, partially submerged in water. Each wheel consisted of a hub, rings and spokes - eight wooden tiles were fixed between the latter. At deck level rowing wheels were edged with borders; On top of the wheels were covered with side metal casings. Open navigation bridges were installed on top of the casings. Service premises were also built on the outskirts.

In the central part steamship, between the paddle wheels was the engine room, and behind it was the boiler casing. Passenger cabins of the first and second classes were located on the deck. At the front of the ship, above the cabins, there was a promenade deck; benches were installed along the railing - three on each side. There were two ladders to access the promenade deck.

The wheelhouse was located in the central part of the vessel. Behind the aft cabins there was a drive compartment, closed on top with a wooden lattice; The drive lines were routed into the wheelhouse along boxes along the starboard and port sides. Make steamship model"Burlak" is not too difficult.

The recommended scale is 1:50, while the length of the “wheel” will be 960 mm - this will be quite enough for both a running model (with or without radio control) and a bench model.

On the deck of the model, bow and stern mooring bollards, an anchor device, and an anchor-mooring capstan are fixed. A chimney is installed behind the wheelhouse - its body is best soldered from 0.3 mm thick tinplate.

The bases of the ventilation deflectors can be made from the same material, and the air intakes for them can be made from plastic balls from children's toys of suitable diameter. The power plant of the ship model is based on the MU-30 electric motor (its operating voltage is 27 V, current consumption is 5 A, power is 40 W, rotation speed is 7500 rpm). To drive the paddle wheels, a homemade two-stage gearbox with a gear ratio of about 20 is used, which ensures a paddle wheel rotation speed of 375 rpm.

Bronze bushings pressed into the base and cover of the housing are used as sliding bearings. Recommended color steamship models: the hull below the waterline, the rudder and paddle wheels are red; the side above the waterline, bulwarks, bollards, capstan, anchor chains, anchors, ventilation deflectors and fenders - black; mast, superstructures, paddle wheel casings above the bulwarks, fish beams, wheelhouse, name of the ship, lifebuoys, railings, awning, vestibule, racks, shelving and fire buckets, as well as benches - white; ladders, decks, side superstructure floors, paddle wheel casings and fenders - light gray; doors, frames of rectangular portholes of superstructures and deckhouses are made of natural wood.
