I-16 type 29

Multipurpose Fighter

Polikarpov

The last serial modification, the I-16 type 29 fighter, was developed on the basis of the I-16 type 24 airframe, and its main difference was in the new armament. The production of the fighter began in 1940. Under the M-63 engine, in addition to two 7.62 mm ShKAS machine guns, a large-caliber synchronized machine gun Berezina UBS, 12.7 mm caliber was installed. The wing machine guns have been removed. The oil cooler, previously located along the axis of the aircraft, had to be displaced and installed in the space between the fourth and fifth engine cylinders.

Under the wing, 4-6 guides for the RS-82 were installed, if necessary, additional fuel tanks with a capacity of 200 liters could be suspended under the wing. Instead of a tail crutch, a wheel was installed. The aircraft provided for the installation of a radio station RSI-3 and a photo-machine gun.

A significant number of I-16 type 29s also had bomb racks located under the wing on the inside of the RO-82. They could carry bombs up to 100 kg. Types of bombs included the high-explosive FAB-50 or the FAB-100, AO-10, AO-20M or FAB-50M bombs, or the ZAB-50TG incendiary bombs.

The fighter was in operation until mid-1943.

Since 1934, a total of 8194 I-16 fighters of all types have been manufactured.

Fully loaded in the I-16 type 29, with underwing fuel tanks and armament, it had a top speed of 382 km/h above sea level and 429 km/h at altitude. Compared to modern German Messerschmitt Bf-109F (maximum speed - 600 km/h and climb time 5000 m - 5 min), the I-16 type 29 fighter had significantly lower flight data, with the exception of maneuverability in close combat.

Analyzing the above table, we can conclude that from the initial I-16 type 5 to the final modification of the type 29, the maximum speed increased very slightly, while the rate of climb, a decrease in the time to climb, improved more noticeably, thanks to the more powerful M engines -62 and M-63 and variable pitch propeller AB-1. The price for the increase in the fighter's flight weight was the gradual deterioration of horizontal maneuverability - an increase in the turn time. The main reason for the slow increase in speed is the relatively small increase in the power of the power plant.

Introduced into service in the spring of 1941, the German Friedrich had excellent aerodynamics, an engine of 1200 hp. exceeded the power of the 29th "donkey" by one third. Its "weak" armament consisted of a 20-mm, or more rapid-firing 15-mm motor-gun cannon, which means it did not require a synchronizer. Having a turn time of 20 seconds, Messer did not even try to engage in a maneuverable battle on the horizontal lines, preferring a vertical maneuver with excess height.
The F-3 was already equipped with a 1350 strong DB-601E, and weapons - one 15-mm MG motor cannon -151/15 with 200 rounds of ammunition and two 13-mm synchronous MG-17 machine guns with 500 rounds of ammunition per machine gun.
