The ChAI-5 ( Russian ХАИ-5 ) was a two-seat Soviet reconnaissance aircraft and light bomber . Made of wooden low-wing aircraft based in its interpretation on the also of Iosif Neman developed Chai-1 .

development

Compared to the original type, a more powerful motor and a two-stage controllable pitch propeller were used. The engine received an extended NACA hood and the entire cell (planking now 1.5–2 mm plywood) and the tail wheel chassis were reinforced. The landing flaps were designed as slotted flaps. Two SchKAS , which were operated by the pilot, were mounted above the engine cowling .

The shooter sat in his own cockpit behind the pilot and operated a hand-operated weapon turret, which was also equipped with SchKAS. There was an internal bomb bay for six FAB-50 free-fall bombs.

A first prototype was completed in December 1934. The first flight tests showed good performance, and so nine more pre-production models were made in 1935, which were tested at the NII . The tests were successful, and so the slightly modified Neman R-10 was mass -produced .

Neman tried to improve the suitability for deep attack and created special variants with the ChAI-51 and the ChAI-52 equipped with a 662 kW Schwezow M-63 , which had a significantly increased forward armament of up to six machine guns. There was also a swiveling machine gun for the observer.

However, due to the imprisonment of Neman in 1939, these projects were not pursued, but the modified engine was also used in series production in the R-10.
