TsKB-26, S.V.Ilyushin
|
Original prototype of the DB-3. Wooden low-wing monoplane with narrow (oval cross-section) fuselage and pilot cockpit 'borrowed' from the TsKB-12 fighter. No gunner position. Wing construction was very strong and light, but required numerous weldings and was complicated.
Test-pilot V.K.Kokkinaki looped the TsKB-26 in presence of Stalin, and gained support.
It was not built in series remaining experimental and record-setting aircraft only, but became a prototype for the all-metal TsKB-30 aircraft;
