The emblem of the Leningrad order of Lenin shipbuilding Institute — sailboat on the open book — a notice to all shipbuilders. Bold design solutions, the movement of the search inherent to the graduates of the oldest institutions of higher education have resulted in many ships and vessels of the national fleet, from the familiar to every commuter boats to giant nuclear-powered submarines.
The ability to build boats of different purposes, to foresee the future of the Navy LCI students learn not only in lectures and workshops, but also in its engineering Department with its extensive research theme. Here are two example their latest developments, earned universal recognition for NTTM-74. These are two models who, in our opinion, may be of interest to athletes modelers.
First of all, the small rescue boat. Its task is carrying out the patrol and rescue operations on rivers, reservoirs, lakes, and within the three mile zone of the sea coast. The last significant p, since it forward to young designers to cut a few conflicting goals. Needed to create a vessel suitable for sailing in river and sea conditions, stable and at the same time maneuverable, unsinkable and high speed.
Well, from that perspective, we can say about the boat LCI? His speed at full load (200 kg or 6 passengers) — 30 knots. The boat does not lose it, and with a three-point rampage. And the buoyancy is provided by filling the double bottom space with polyurethane foam.
Original design solution of the case. Spacious open self-draining cockpit, something resembling a bath, folding side ramp, through which it is easy to take on Board the victim right from the water, Chine planing trimaran contours are the most important of its features. The designers thought about the experience of the driver, his seat with the controls of the boat made up high: increased visibility, freeing up additional space in the housing.

Fig. 3. The location of the main components and assemblies of high-speed submarine:
1 — interchangeable nose cones; 2 — battery; 3— connector housing; 4 — steering gear; 5 — automatic start; 6—automatic movement; 7 — propeller motor; 8 — stabilizer; 9 — horizontal steering wheel; 10 — coaxial propellers.
With a length of 6.5 m and width 2.5 m boat has a high maneuverability. This is achieved through the use of water jets (which, incidentally, has enhanced the safety of work with victims). You can add that the boat is equipped with awning to protect from the weather and two soft seats.
Very different goals pursued by the young designers of the LCI, when he worked on high-speed underwater model sporting destination. I must say that the construction of models of submarines is very common among our modelers and results in the competitions they achieve good. According to preliminary data, Leningrad udlos to take another step forward. Their skorostnaya underwater, if TVK can Varbitsa, “one and three pitvh”. Depending on the conditions of the competition and the goal at her schwada three different noses ,obtectus, the calculation of which was glavnym in the design model.
The hull of the submarine is made of Stekloplastik. Its length is 1530 mm, naibolshie diameter — 132 mm Elektrodvigatel, drawing power from accumulators, ruslive power NV shaft 1,1 HP urlset two coaxial propeller, Vint, is controlled by a special avtomate. Automatically made and the control of the steering bushinkai. The appearance of the model and its main uspi pokutny in the figure.
