The Neman R-10 ( Russian Неман Р-10 ) was a direct further development of the ChAI-5 for series production. It was a two-seater Soviet low-wing aircraft with a retractable tail wheel landing gear, which was essentially made of wood. It was used as a reconnaissance aircraft , light bomber and for deep attack. The designer was Iossif Neman .

development

Compared to the original type, a Soviet engine, a Wright R-1820 manufactured under license, and a WISch-6 propeller with hub fairing, also from Soviet manufacture, were used. The rudder was enlarged. A wheel was mounted in the rear instead of the grinding spur. The windshield was given a conventional bottom-up incline and a heater was provided for the crew. 8 mm thick rear armor was installed to protect them.

The engine was covered by a NACA hood . The cell paneling was made of 1.5-2 mm plywood. 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, in which the reconnaissance equipment could be housed.

The scooter trials began on June 7, 1936 and at the end of the month the prototype started its maiden flight. After 42 flights, the factory tests were completed and the R-10 was handed over to the armed forces, who tested the aircraft extensively from August to October and confirmed its suitability with a recommendation for series production in November 1936. The first series machine was handed over to troop trials on May 1, 1937.

The actual series production started in September 1937 in the agricultural machinery combine in Saratow , but very slowly because of the untrained staff. Two plants in Kharkov and Kiev were also included in the production. In August 1938, production was interrupted due to poor quality. After a technical commission was set up to monitor production, production started up again in April 1939 and continued until the beginning of 1940. A total of 528 R-10M-25A and R-10M-25W were built.

The machine took part in the fighting in 1939 in the Japanese-Soviet border conflict , the occupation of eastern Poland and in the winter war against Finland, where it was partially equipped with skis. She was also used at the beginning of the German raid in 1941, but suffered heavy losses. The last R-10s were pulled out of the front line in the summer of 1944 and handed over to flying schools, where they flew until the end of the war.

Neman PS-5

Over 60 disused military aircraft were demilitarized and converted into civil aircraft for Aeroflot . This type was called the PS-5 and could carry three passengers and cargo.

A total of 528 machines of this type were manufactured with the prototypes.
