The first Soviet all-metal aircraft. It was built as a technology test platform.
Pilot's open cockpit was located right behind the engine, above the wing leading edge. Two passengers were seated
face-to-face in narrow toll fuselage of triangular section. Project started in May
Fuselage and wing frame was assembled of domestic aluminum alloy ('Kolchugaluminij')
profiles. Skin - corrugated kolchugaluminij. Ailerons and elevators had rigid controls,
rudder - wire controls.
Construction was very light, new design team (including A.I.Putilov,
V.M.Petlyakov, I.I.Pogosskij, E.I.Pogosskij, N.S.Nekrasov, B.M.Kondorskij, A.I.Zimin
et al) proved to be a serious competitor for Junkers (who dominated market of metal aircraft at the time).
First flight took place on May 26, 1923 (engineer N.I.Petrov).
The only modification required was done quickly - slightly
increase of the tailfin. Official acceptance trials in presence of deputies from UVVS
and TsAGI - May 28, 1923.
There were still no domestic 100hp engine available, and passenger capacity was too small for mass use. ANT-2 remained
a technology demonstrator, but first step to all metal monoplane concept was made.
