Ilyushin Il-10

 

il-10

 

To provide a replacement for the II-2 Shturmovik (ground-attack aircraft), the llyushin design bureau developed two different prototypes in 1943. The Il-8 and Il-10. The Il-10M attack aircraft was created after a proposal by the Soviet Air Force Marshal Pavel Zhigarev.
 
The II-8 was rejected by the Council of Ministersin favour of the contemporary llyushin Il-10 M, which first flew on 2 July 1951, piloted by Ilyushin’s chief test pilot V. Kokkinaki.. The Il-10 was a completely new design of all-metal construction and improved aerodynamic form. It provided better crew accommodation, the gunner seated with his back to the pilot in an enlarged cockpit, and both crew members were located within the protective armoured shell. Revised main landing gear units retracted within the wing, eliminating the large landing gear fairings of the II-2 and requiring only small fairings over the pivoting mechanism.
 
Early favourable reports of the prototype test programme led to a batch of pre-series machines, quantity production being initiated in August 1944, with evaluation in operational regiments starting two months later. The type was used first in operations in February 1945 and by that spring output reached a peak. Many regiments re-equipped with the Il-10 before the German surrender, and a considerable number took part in the brief but large-scale operations against the Japanese in Manchuria and Korea during August 1945.

Production of the Il-10 continued post-war with Soviet factories building 4,966 machines, the last leaving the production lines in 1955. Additionally, ll-10s were also built at the Czech Avia factory, under the designations B-33 and CB-33, the CB-33 being the equivalent of the II-10U trainer variant. Czech production finished in 1954 when over 1,200 examples had been completed.
 
From 1951 onwards Soviet production had concentrated on the II-10M which featured an entirely new wing of revised planform and deeper aerofoil section, a slightly lengthened fuselage, modified landing gear with increased track, increased fuel capacity, and significantly improved armament. However a lot of equipment that the designers had planned to install on the new machine needed numerous improvements, and so production of the Il-10M started only in 1953. There were 146 aircraft built.
 
The Shturmovik was armed with four wing-mounted 23-mm NR-23 cannons, plus one 20-mm B-20-EN cannon installed in the VU-9M rear turret. The normal ammunition load was 600 shells for the NR-23’s and 150 shells for the rear gun.

Aside the cannon armament the aircraft could carry 400 kg of bombs and up to 600 kg in an overloaded configuration. The bombs were loaded into two bomb bays and on external BD-2 mounts fitted under the fuselage in front of the bomb bays. Additionally the Il-10M could be equipped with BD-3 bomb mounts on the wing hardpoints.
 
Alternatively, the new machine was able to mount four launch tubes on wing pylons that were capable of shooting unguided rockets.
 
The aircraft was quite heavily armored for its time. The plating varied from 4 to 16 mm near the rear armored wall. The armor protected all of the main parts of the aircraft’s power plant, control elements and crew cabin.
 
The Il-10M was powered by the AM-42 engine which was capable of producing 1750hp and fitted with a 3.6m diameter, three-bladed AV-5L-24 propeller.
 
The pilots who flew these machines noted a significant increase in controllability and stability in flight over the Il-10. Nevertheless the Il-10M didn’t get a chance to see combat. It was not ready for the conflict in Korea, while later conflicts were dominated by jet-powered aviation.

The Il-10 formed the sole equipment of Soviet assault units for a number of years and was also used widely by Warsaw Pact countries. Other Communist countries to employ the type included North Korea in the opening stages of the Korean War in 1950. Losses were heavy and the type was obsolete but, Il-10s remained in service with the Soviet V-VS until 1956 and with various satellite air arms for several years longer. For some time after that they were flown as gunnery trainers but they were decommissioned in April 1956 and all the crews were reassigned for further training on jet aircraft. most had been scrapped by the mid-1960s.
 
The Il-10 had been tested with a ZhRD-1 auxiliary rocket engine in the rear fuselage to provide short-term performance boost, but this modification was not adopted. The llyushin bureau strove to develop later shturmovik designs, including the II-20 single-seater and the Il-40 with twin turbojets, but official encouragement was minimal.
 
The Il-10M became the last mass-produced piston-powered attack aircraft designed by the Ilyushin design bureau.
