Three-seater sesquiplane flying boat of unique layout. Aircraft had no struts between wings,
lower wing was integrated with balance floats. Landing gear could be raised for water surface operations.
Another interest aspect of Sh-1 story: It was a homebuilt aircraft! V.B.Shavrov,
V.L.Korvin and mechanic N.N.Funtikov manufactured all parts in the city apartment.
Aircraft was assembled at one of Leningrad airfields.
First taxi on water was carried out on June 4, 1929 (L.I.Giksa). After minor
modifications (floats shape) aircraft was flown
on June 21. During one week (July 1-8) pilot B.V.Glagolev fulfilled trials program in harsh weather conditions (wind up to
7.5m/sec and waves up to 0.6m).
After those trials landing gear and tail skid were installed. Few dozens of flights were performed as an amphibian - landings
and takeoffs were performed on the ground airfield and water surface. For State Trials Sh-1 was flown from Leningrad to Moscow
Central (Khodynka) Airfield.
During September 20-28, 1929 aircraft was carried through complete trials
program (pilots B.V.Glagolev, M.A.Korovkin,
A.V.Chekarev). Conclusions was that with its 85hp engine Sh-1 may serve only for sport/training goals. It was also noted
that proper engine cowling could improve the performance.
Sh-1 was transferred to Leningrad Osoaviakhim for propaganda flights. On February 26,
1930 it was crushed by V.P.Chkalov, who
hit the railroad signal while flying along the October Railroad (Moscow-Leningrad) in heavy snowstorm/icing conditions. Pilot and
mechanic Ivanov were unharmed, but aircraft was found unrepairable.
