Tri-type towboat created in RF

23
In November, tests of the tugboat on the basis of the trimaran construction of the development of the Volzhsky Shipbuilding and Ship Repair Plant will begin. On the benefits of a new boat, created for engineering troops, portal Flotprom told the deputy director of the Group of Companies "Vega" Pavel Glukhov.




“The tugboat (BMK) was designed on our initiative on the basis of the tactical and technical characteristics developed by the“ Institute of Engineering Troops of the Russian Defense Ministry ”. We designed it specifically for the Ministry of Defense. When the designer of our company began to create this boat, of course, we studied the prototypes existing in Russia - BMK-460, BMK-225, BMK-130, as well as tugboats made in China, Germany, France. Met with those who apply them. After that, we had an idea and as a result we created a boat based on a trimaran. This allowed to improve the basic characteristics of the boat and protect the power unit from mechanical influences. Since the BMC works in shallow water, the previous samples were characterized by “sucking” to the muddy bottom. We have excluded such a phenomenon, because the space between the main body and the sponsons, which form the trimaran structure, is made flowing, ”said Glukhov.



He stressed that the boat is equipped with a domestic engine. “Its power when operating optimally is 550 hp, and maximum power reaches 600 hp The thrust of the screws is 4700 kg, with a slight refinement of the screws, the thrust will increase to 5700 kg. Thanks to the joint work of the designers of the company with the experts of the Technical University of Volgograd and the Balakovsky Plant. Mom's were created compact and lightweight gearbox, which allowed to keep the mass of the power unit within 1,5 tons. Through the use of rotary steering rotors allows you to control the thrust vector. According to the mathematical modeling, the boat will have good maneuverability, stability and controllability, ”said the deputy director.

The body of the prototype is made of metal, but in the future it is planned to switch to composite materials.

“The floodability of the BMC is ensured by dividing the case into four compartments,” said Glukhov. - The cabin of the boat is made of polymer materials sealed, able to withstand the impact of the shock wave in accordance with military requirements. It is designed for two people, one of whom manages a watercraft, and the second works with ferries and pontoons. ”



The boat has air filtration equipment for working in the contaminated area. Overview provide two cameras mounted in the bow and aft.

“Already in the process of construction, his other possible uses were also revealed, not only the military. For example, it turned out to be very useful, oddly enough, for the Ministry of Agriculture in the land reclamation system. It is necessary for him and the Ministry of Emergency Situations where natural disasters associated with floods, river floods occurred. Delivering a ship there is not always possible. This boat is transported very easily on domestic cars such as KAMAZ or KRAZ. Able to move cargo, direct ferries, transport people, be an ambulance, fire, anyone. Another advantage is the system for connecting with pontoons, made in a flexible version in contrast to the rigid coupling used in older models of towing and motorboats, ”he explained.



Boat length - 9,2 m, width - 3,2 m, dry weight - 9 t, speed - up to 21 km / h, power reserve - 10 hour, fuel consumption per hour - 35-37 l. The declared life of the hull of the boat - 20 years, the engine - 2700 hour. before the first repair.

    It's nice to see dual-use developments.

        - Probably not yet built “in metal”, adopted the concept, started designing, glued the model of the future machine.

      It would be nice if you liked the boat, it’s very original, and it’s easy to see in operation. But eats, probably, immeasurably.

        fuel consumption per hour - 35-37 l - this is from the article
        Using a tugboat as a fishing tool is from the same series as coming to participate in Formula 1 on a Belarus tractor)

        In the city of Sheksna, one fisherman mastered the manufacture of punts from profiles for GKL / GVL and plywood, not very different in design from this pepelats. yes The design turned out so successful that he does not have time to fulfill incoming orders. Himself even hung a small motor on it. True, he does not recommend it to others ...

          Well, motors are now trying to hang on everything, even on the board. (although the board does not already have a variable thrust vector, like a boat engine yes )

        Well, I would not say that the "Whirlwind" is frail. "Whirlwinds" of 20 horses and above. Let's just say any outboard motor has a variable thrust vector. yes

    - Well, the photograph shows the layout of the boat, that’s understandable. But why such weird backgrounds ?! It seems that this boat designed and built a model of some kind of nugget, hastily photographed in his yard and sent pictures with the concept of the model of the research institute, where they decided to make it in metal, but they did not bother with the photos and slapped what was sent to them. This, of course, is a delusional hypothesis, but nothing better, looking at some ancient boards and no less ancient, jagged borders against the background of residential buildings does not occur.

      Apparently, the designers took the model to the loggia to take a picture in good light.

    on domestic cars of the KAMAZ or KRAZ type Well, KRAZ is definitely not a domestic one, he’s now a “foreign car”.
    And since the cutter is not bad, go fishing. (Although you can buy a lot of fish for money for fuel).

    Boat, and even the rear pontoon and fishing. Noble fishing will work.

    How many lovers to pour from empty to empty! Let them start at the beginning angry and then share the hide! (I agree about fishing laughing ) And with such proportions, IMHO, the catamaran is better, or the usual bottom is even better!

      Well, don’t tell me ... In this model, the lateral sponsons act as the protection of the screw-steering complex, they are the power supporting structure during transportation and directly during operation ... So, in my opinion, the layout solution is very competent.

        the trimaran is almost square in shape, the catamaran is half the width! And this, - for fishing and then to the lake! (width - one to three lengths! ordinary barge)

          Why did you get this ??? Trimarans, like other multihulls, can have completely different dimensions ... It all depends on the purpose ... In this case, it is the size of a regular pontoon boat, if I'm not mistaken. This boat should be transported in the back of a truck, so its size is determined by this.

    Three floats (M-shaped hull contours) on the trimaran mean with a larger deck width a smaller wetted surface of the underwater part of the vessel. Which accordingly increases speed and at the same time greater stability and large safe angles of heel, and hence greater seaworthiness.
