TOM-1 by P.E.Richard (OPO-4)

Maritime torpedo carrier (so TOM). All-metal (duralumin) two-engine monoplane with tailplane installed high on the tailfin. Unlike other contemporary Soviet aircraft, TOM-1 had smooth skin (0.5 to 0.6mm) supported by stringers placed at 10 to 15cm. Ribs were installed within ~40cm from each other. Aircraft airdynamic quality was on very high level for the time.

High aspect ratio (8) wing narrowed towards the tip and carried ailerons and slats (could be lowered to 40°). Armament was installed in 3 turrets (the ventral one was retractable).

TOM-1 construction was light and strong, but work consuming and expensive (number of rivets was twice more than for the TB-1). Consumption of sheet duralumin was extremely high, a lot of material was lost at lightening holes.

Half-assembled, TOM-1 was transported to Sevastopol on January 1, 1931. There assembly was completed. Flight tests continued until August 1931 ( N.I.Kamov and N.A.Kamkin). Performance was quite good.

At the more conventional and cheap TB-1 was already in production. Its floatplane version was almost ready. As a result, TOM-1 was rejected as expensive and complicated aircraft with similar performance.
