The Schavrow Sch-2 ( Russian Шавров Ш-2 , pronounced scha-dwa ) was a Soviet multipurpose amphibious aircraft of the 1930s and the most successful development of the designer Vadim Schavrov .

development

Shavrov relied on the light amphibious flying boat Sch-1 from 1929, which he had designed together with W. Korwin as an employee of Dmitri Grigorowitsch in Plant No. 3 "Krasny Lotschik" from 1925, enlarged and improved the new design however. As a typical design feature of a Shavrow flying boat, the type received the characteristic lower stub wings with support floats and landing gear. The engine was attached to the upper wing in a splash-proof manner, which in turn was connected to the hull by struts. The later production series had a closed cockpit.

The first prototype took off on its maiden flight on November 11, 1930 and testing was completed in the summer of 1931. Subsequently, serial production began at Plant No. 31 in Taganrog , where 270 aircraft had been built by 1934. The WWS took over 50 of these and used them at flying schools. About 20 went to the polar air fleet ( Russian Полярная Авиация ). Later in the 1930s, another series of about 50 Sch-2s was made at the Leningrad Repair Plant. A few years after the end of the war, the model was reissued in Irkutsk in 1951/52 .

The Sch-2 proved to be very robust and served both in the civilian and in the military as a transporter, training and liaison aircraft, for supplying Arctic base camps, as a border patrol flying boat and in fisheries control. Some Sch-2 served as board aircraft on icebreakers . 14–16 aircraft were equipped with two stretchers for the transport of the sick and were called Sch-2S .

The exact number of aircraft built can no longer be determined today; a total of between 300 and 700 copies are said to have been produced. The last Sch-2 is said to have not been retired until 1964.

On November 8, 2018, to mark the 120th anniversary of Shavrov's birth , a copy of a Sch-2, built by the amateur designer Alexander Selesnjow and designated as the Sch-2.017-bis , was presented. This aircraft received a slightly enlarged fuselage and a new engine. Seleznyov is planning a series production of the Sch-2.017-bis .
