I-2
Country of origin
Soviet Union
The Grigorovich I-2 was a biplane fighter aircraft of the Soviet Union, the first indigenous fighter to enter service in substantial numbers.
The I-2 was developed from the prototype Grigorovich I-1. Construction of the initial aircraft was started on February 1, 1924 and finished September 6, 1924, with A.I.Zhukov as the test pilot on the maiden flight on 4 November 1924. The aircraft was fitted with a 400 hp Mikulin M-5 and was found to be 20 km/h faster than the I-1 with improved engine cooling. Zhukov noted that the I-2 handled well, easy to land, and required a short runway for takeoff. After improvements to load-bearing surfaces, steering, and other control systems, Zhukov noted that at low throttle it suffered from random nose lift and had a tendency to dive when accelerating. He refused to continue testing after the sixth flight. The I-2 was produced at the Dux Factory, with 52 aircraft completed before being supplanted by the I-2bis model. These aircraft entered service with the flight school at Borisoglebsk (air base) in 1929.
Pilots M. M. Gromov and V. N. Filippov flew the I-2 on 19 November 1924 and did not note these same tendencies to nose lift or dive. They did, however...
