SEAPLANE W-2. Scale model 1:33.
In Russia in the late 20-ies of the last century there was an urgent need in small aircraft for communication with remote facilities. Especially this problem existed in the Northern regions, Siberia and the far East, where there was no other means of communication.
In 1928 the Leningrad young designer Vadim Shavrov together with Victor Korovin and Nikolai Puntikov decided to collect amphibian. The development and Assembly of the aircraft took place on pure enthusiasm at the apartment of Victor Korovin. After 13 months ready of the aircraft, the boat, the fuselage ,wings and tail made through the balcony of the apartment Korovin on the street and finished the Assembly in rowing port. W-1,such designation received small plane rose into the air 21 Jun 1929.
In 1930, V. Shavrov creates your second plane-amphibian sh-2 ,which differed from
Sh-1 domestic engine M-11 and up to 150 kg flight weight. Boat W-2 was longer than W-1 at 0.5 m, and increased the size of the top of the wing. Now in the boat besides the pilot could fit 2 more passengers. The first flight of the sh-2 was held in November 1930 and six months later, the aircraft successfully passed state tests and in 1932 became mass-produced. The last flight W-2 was held in 1964. There is evidence that in some parts of Russia it is used and now, restored or rebuilt by the hands of craftsmen and enthusiasts.
W-2 had a heroic biography. The plane was used during the development of the far North, on the Kola Peninsula, in the rescue “Chelyuskin” in the far East, Siberia and Central Asia. It was used to communicate with remote areas for ice and fishing exploration, aerial photography, air ambulance and on the fronts of the Finnish and the Second World War, where it was used for reconnaissance and evacuation of the wounded.
Aircraft sh-2, where the pilot grandmother took out two “Chelyuskinites” on the mainland is on display at St. Petersburg Museum of Arctic and Antarctic.
When creating this model, sh-2 were used materials of the amphibious aircraft of the air-link trust “Apatite” in Khibiny tundra, which was operated by the pilot P. Ovchinnikov.
DESCRIPTION OF THE AIRCRAFT. The fuselage-one-piece construction assembled from wood and plywood, covered with fabric, is a boat. Aircraft – polytropes with pulling sintomatico band on the upper wing, with a triple cabin, with the rising of the chassis, the axis of which can dress up the wheels or skis. The lower wings of free-carriers located close to the waterline, carrying the floats lateral stability. The upper wings backed, can be folded back for easy storage. Lifting and lowering the chassis are made from the cockpit. The plane is amphibious ie can produce takeoff and landing on water and on land, and with the skis on the snow and ice.
It is a light plane of mass use/
Boat plane has a large open cabin, in which there are two seats for pilot and passenger, the third seat is behind the seat backs, where you placed a spare gas tank, this space can be used for the transportation of small goods.

ASSEMBLING the LOWER wing AND the FLOATS (Fig.4) Assemble the lower wings, children 57,70,71,104., if the ends of the wings do not flap folding section glue with a basic rib No. 4. Assemble the floats and put them on the lower wings, glue the lower wings to the fuselage (the place of gluing the marked sections of the fuselage 8-12 and 12-14). To the ends of the lower wings were folding in them is fixed the hinge from the tube dressed on a bracket for the stapler and clip a piece of floss with a length of 3 mm., which on the one hand glued to the main part of the lower wings , and the other enters the hole in the rib of the folding part.
Mounting the TOP of the WINGS (Fig.5)
First collect the ailerons, and then the upper wings, though the upper wing is going in the collapsible embodiment, the rib No. 1 is necessary to pierce or drill a hole of 2 mm diameter in her bow. The spars have to install all the ribs for the whole wing, and for moving the ailerons instead of the ribs 8 to 13 can be set equivalent patterns 108 and 109, the ribs of the ailerons are cut from the ribs of the wing -they are shown in dark color. In order for the ailerons to turn,
they inserted a wire with a diameter of 0.5 mm, which is adjustably secured on the ribs 6 and 15. Details of 37-:-42 going to the center, for not folding wings, the center section, make whole, and for the variant with folding wings – made of two parts connected by a hinge. The hinge is made from three tubes mounted on a wire, the middle tube is fixed on the fixed part of the wing , and two outer tubes on the movable part. With a hinge, similar to which were fastened the ends of the lower wings and the same retainer, the upper wings are attached to the center section.
The struts of the upper wings also run folding, so the folding wings need to unhook from the wing, from 77-78 parts to make a tube and insert inside wire diameter of 1 mm., the end of the wire going to the wing to bend at an angle of 120 degrees and insert into the hole on the bottom of the wing, and the other end of the strut attached to the fuselage with a hinge, the design of which is described above.
