I-2, D.P.Grigorovich
|
Biplane fighter, developed from the D.P.Grigorovich I-1. It had same size, but wing had no 'V' and ailerons only on the lower wing. Engine cowling was radically improved. Aircraft was armed with pair of synchronized PV-1 in the nose.
Work on the project started in Spring 1924, in tight contest with N.N.Polikarpov IL-400. I-2 was finished in Fall 1924, and with experienced test-pilot A.I.Zhukov on controls demonstrated very good performance. It was 20km/h faster than I-1 and had much less engine cooling problems.
Decision was made to start production of the I-2...
But several shortcomings were revealed soon. First, A.I.Zhukov was a tiny man. Average size pilots could barely push themselves through narrow cockpit opening. Serious complains were expressed about restricted sight, control pedals location and weapon control.
Aircraft was redesigned and became I-2bis.
