The Ilyushin Il-16 ( Russian Илью́шин Ил-16 ) was a Soviet light ground attack aircraft that was developed by the Ilyushin design office at the end of World War II . In principle it was a smaller version of the Ilyushin Il-10 , but was powered by a Mikulin AM-43NW. It was hoped that this would result in a higher speed and better maneuverability than the predecessor. However, it turned out that the defects in the engine could not be remedied and so development was stopped in the summer of 1946.
development
The Il-10, which already had a high level of performance, was to follow with the Il-16 in 1944, a light ground attack aircraft with higher speed and better maneuverability. The new design was powered by a water-cooled Mikulin AM 43NW engine , which had a take-off power of 2300 hp. The design was practically identical to the Il-10, both aerodynamically and structurally, but smaller and lighter. Together with the more powerful engine, the Il-16 should be significantly faster. The fuselage was made of Ilyushin's tried and tested armor, which, however, was lighter than that of the Il-10.
The machine had the same Nudelman-Suranow NS-23 cannons as the Il-10, which were also mounted in the wings. In addition, a couple was SchKAS - machine guns installed in the outer wing panels.
A rear-facing Berezin B-20 was available to the gunner . In addition, he was able to use a magazine of ten AG-2 air grenades to repel pursuers. The standard bomb load should originally be 200 kg, which should be accommodated in two bomb bays in the inner wings or attached to suspensions under the wings and which could be increased to up to 400 kg. The standard bomb load was eventually increased to 400 kg, which could be increased up to 500 kg.
The exact number of prototypes built is unclear. Some sources name three - there are photos of two machines. The first flight took place in 1945. The torque of the engine, combined with the relatively short hull, led to poor longitudinal stability . To solve this problem, the fuselage of the second prototype was lengthened by 500 mm and the area of the horizontal stabilizer was enlarged and a trim rudder was added. Although these changes improved the flight characteristics of the machine, the engine proved to be unreliable and extended the flight tests until 1946. However, the problems persisted and development was discontinued in the summer of 1946.
