The first flight of an experienced fighter with the engine M-22 (licensed version of the American R-2 “Cyclone” company “Wright”), piloted by test pilot of Zavod No. 39 V. P. Chkalov, on December 30, 1933. Followed in January of the following year in the air raised the second prototype, but with the engine R-2 “Cyclone” made in the USA.
Flight tests showed that the most preferred was the fighter with the engine of domestic production. It was a high maneuverability, easy out of the tailspin, however, when planting required high alignment. Speed and manoeuvring characteristics of I-16 surpassed its competitor And-14, created by the team of P. O. Sukhoi under the overall supervision of A. N. Tupolev and also with retractable landing gear.
The prototype I-16
1 may 1934-16 And-14 and the biplane I-15 was first shown to the public during the parade on red square. In the same year was the debut of I-16 at the international aviation exhibition in Milan (Italy). Brightly colored fighter seemed like ASB sport plane, capable of flying at a speed of 467 km/h.
At the same time was the development of the serial production of the fighter factories № 39 in Moscow and No. 21 in Gorky. In 1937, production of the new machines hooked up a plant in Novosibirsk in 1940 in Rostov-on-don, and at the end, and No. 600 – Urumqi (China).
Fighter continuously improved, equipped with more powerful engines, and changed his weapons. But the basic size and contours remained unchanged.
In 1934, the factory in Moscow produced 50 machines. But the production I-16 increased from year to year, and in 1940 their production at the factory in Gorky peaked – 2007 fighters.
The last-16 was built at the plant № 458 in Rostov-on-don in 1942. The total release of I-16 of all modifications made 10 of 292 cars.
In 1936 I-16 began to be installed more powerful engine M-25. The most popular variant of the fighter was a type 5, equipped with the engine M-25A is a Soviet copy of the American F-S “Cyclone”. During factory test the I-16 type 5 has reached a speed of 456 km/h at an altitude of 3000 meters.
The main structural material of the aircraft was wood, aluminum alloy and steel, which helped reduce the cost of the machine.
The fuselage was a frame of four spars and 11 ribs put on him a shell (covering), is laminated veneer. The tail part of the fuselage had a removable duralumin spinner for ease of installation and adjustment of the angle of the tail.
The wing consisted of two outer brackets and the center section, which attaches the rest of the units of the airframe, undercarriage and engine. The center section consisted of two truss spars, connected by ribs and tubular bracing. Cladding – combined, the top near the joint with the fuselage is plywood, and starting with rib No. 2 – dural. From the bottom to the center section along with a shell attached to the dome of the landing gear.
The detachable part of the wing design is similar to the center section. And the front part of the wing trimmed top by 44.5% and below 14.5% of the chord duralumin sheet thickness of 0.6 mm and then the tight fitting fabric impregnated with a protective dope with painting. On the wing was hanged drooping ailerons that acted as flaps when landing.
Frames ailerons and tail surfaces were made of aluminum alloy, while the keel of the aircraft with engines M-25A was mounted at an angle 2 degrees to the right to parry reactive moment. The stabilizer is adjustable on the ground in the range from -3 to +3 degrees.
Chassis two-wheeled with spike support. The main landing gear is made in two rod of the pyramids, their cleaning and release was carried out using a mechanical winch located on the starboard side of the cockpit. Wheel size 700×150 mm had mechanical brakes.
Fighter I-16:
1 – propeller; 2 – tank; 3 – fuel tank; 4 – battery; 5 – dural hinge of the rudder; 6 – cooler; 7 – tension band of the engine hood; 8 – cable mechanism cleaning and release of the chassis; 9 – coil spring cushioning-spike; 10 – flap cockpit; 11 – guide tube; 12 – slide; 13-gun ShKAS; 14-metal ribs; 15-glass hatch of the backlight of the dashboard; 16 – the headstock of the rudder; 17 – strut suspension; 18 – cable closure flap wheel suspension; 19 – rubber band; 20 – cable of the main wheel of the landing gear; 21 – Venturi
The canopy in the center had a hole under the scope of Op-1, a grid, and for ease of landing the pilot it moves forward.
In the period from 28 August to 3 November 1935 And ten-16, built at factory No. 39, passed military tests in the 107th squadron Bryansk aviation brigade. Military pilots studied all the weak and positive sides of the aircraft, its combat use. It was found, for example, that drooping the ailerons, reducing takeoff and landing capability of a fighter allowed to exploit the I-16 on existing aerodromes, without waiting for their reconstruction. But soon from this technical solution is still refused, going to the landing pads.
It was noted the ease of control of the aircraft, sensitively reacted to the slightest deviation of the rudders, but on the turn and landing “perebiranie” pen threatened to stall into a spin. The latter circumstance complicates the use of weapons, since the slightest error in piloting led to the violation of the sighting. But maneuverability it was on top.
Barrel-16 was performed in 1 – 1.2 seconds, and the plane was always possible to fix and in an intermediate position. Confirmed military pilots and test previously identified by the swelling of the upper cladding planes in flight with a maximum speed that was required to increase the number of ribs in the wing.
In General, drill the pilots came to the unanimous conclusion that the plane has excellent flight qualities.
Baptism of fire I-16 type 5 was held in Spain, where the fall of 1936, received the first batch of 31 vehicles. Together with the aircraft arrived and the pilots-volunteers from Bryansk air brigade, led by captain Alexander Targowym. -16 in the skies over Madrid for the first time appeared on 9 November and immediately changed the nature of air combat. This was especially true of the new admission – the fighting in the vertical as the I-16 were significantly superior to German fighter Not-51 and Italian S. K. 32. In this regard it is appropriate to quote the words of a participant of the war in Spain, A. I. Gusev:
“I-16 <…> was subordinate only to the pilot who is fluent in the technique of piloting, especially at low speeds, low altitudes, with a sharp evolutions… the loss of speed on the left turn he (the fighter. – Approx. ed.) was free to break as in the left and right spin. Not only me, but all my companions in the group, <…> And-16 resembled a skittish horse that needs a constant, incessant attention.
-16 chassis was cleaned manually. This was done so: after takeoff at low speed and the height of 15-20 meters, the pilot removed his left hand from the Gaza strip took its control knob, and the right was cleaned chassis. Had to do more than 40 turns of the handle. If the speed has increased, the chassis will not be removed without great physical effort”.
Later, when the Soviet Union brought the captured samples of the fighters, the Soviet testers noted, in particular, that “…the I-16 with all the attacks <…> SR-32 in the case of timely detection attacker could exploit the advantage of speed and climb rate to get away from the attack with a subsequent turn up, and having the advantage of height, in turn, attack the enemy.”

About the same was the case with the German fighter is Not-51.
But the situation in the sky of Spain began to change, when there appeared the fighter of the next generation VF.109, yet with a 680-horsepower engine Jumo-210. Compared to the Soviet fighter “Messerschmitt”, though inferior to him in speed and climb rate, has demonstrated the best maneuverability in the horizontal plane accelerates faster in a dive, and flying qualities have been much simpler.
At that time nobody thought that after a few years I-16 will meet again face to face, but with significantly upgraded In^109. But even the upgraded I-16 with a 1100 HP engine M-63 and cannon armament could not effectively compete with much “gone” forward “Messerschmitt”. Although, according to participants in the battles, 1941 – 1942, I-16 was a serious contender (especially cannon) German aces.
In early 1938, the Polikarpov design Bureau was transferred to the plant № 156, which had previously worked, was arrested in November 1937, A. N. Tupolev. To create the cannon versions of the fighter type 17 on the basis of the type 10 that the wing guns were replaced by two 20-mm cannons ShVAK. Additionally provided for suspension of up to 200 kg of bombs. Takeoff weight increased to 1810 kg. Speed was reduced to 425 km/h, deteriorated maneuverability. But it was not so important, since the aircraft was to be used against bombers, to whom he was very dangerous.
Summer in Gorky began testing the I-16 type 18 with the engine M-62 (830/900 HP) and a variable-pitch propeller (original VISH-6A, then AB-1). Armament was consistent with the type 10. Due to the heavier engine improved longitudinal stability, as the alignment moved forward and did not exceed 27.2% of the mean aerodynamic chord (SAH). The rate increased to 461 km/h, improved rate of climb.
In the same 1938 there was the I-16 type 24. The plane had the engine M-63 take-off power of 1100 HP. (nominal -930 HP). The first three M-63 plant No. 19 was produced in 1938 and until 1941, handed over to the customer 3087 motors. Radial engine M-63 was developed by designer A. D. Shvetsov on the basis of M-62 and had increased to 7.2 compression ratio vs. 6.4 at M-62.
In addition, the I-16 type 24 strengthened wing, mounted fotokinopulemeta and external fuel tanks. The maximum speed at an altitude of 4800 m was 489 km/h. Normal takeoff weight was 1780 kg, maximum -2052 kg. Cannon modifications of I-16 with this engine received factory designation type 27, 28.
In the early 1940 AND-16M-63 in accordance with the decision of Committee of Defense № 223 dated 25 may launched into serial production at the factory in Gorky. The first batch of these fighters were sent to military trials where there is lack of reliability of the aircraft. However, the release AND-16M-63 increased.
At the end of the same year, the standard of this machine is presented to the control tests in NII VVS. Compared to predecessor serial one manned jet guns – guiding beams for the suspension of rockets RS-82 caliber of 82 mm. Essential innovation for the fighter was the radio station, which gave the mast with the antenna.
All these innovations had a negative impact on the flight performance of a fighter. As follows from the report on the results of state tests, the aircraft did not eliminate the defects revealed in the early versions of the machine. In particular, it was noted the insufficient strength of the hood of the engine and exhaust pipes was not a thermal mode of operation of the motor, the fighter continued to suffer a lack of stability in flight. In addition, it was found that prolonged dive the car was sucked into this mode and at the same time due to the lack of rigidity of the wing started to rotate. The dangerous for the machine modes of the flight the pilot had to apply excessive force to the handle and the pedals to control the airplane.
Despite this, the technical Council of the air force Institute headed by its chief General A. I. Filin stated that the I-16 with the engine M-63 test stand. At the conclusion of the Institute it was noted in particular that the “plant No. 21 for a number of years ignores the NII VVS at eliminating defects of the plane I-16. Factory No. 21, with modifications of <…> And-16 is not brought to the required value of the maximum speed of the aircraft, resulting in <…> And-16 with the M-63 is significantly inferior to <…> for the fighters.”

Last-16 passed the state tests in NII VVS in summer 1940. He was equipped with the engine M-63, and the two synchronized and two wing Scusami.
After the war in Spain And 16 demonstrated their abilities in the skies of China. The peak of glory of I-16 occurred in 1939 during the fighting at Khalkhin Gol (Mongolia). Then the main opponents of Soviet pilots, there were pilots of the Japanese fighters I-96 and I-97. The latter, although he was equal in his fighting capabilities And-16, is still inferior in speed and vertical maneuver. In 1939 – 1940 “donkeys” was used in the winter war with Finland. The biggest challenge for the I-16 became the Great Patriotic war.
Despite the fact that the I-16 by the time obsolete, for some time he was still the main fighter of the early period. Soviet pilots showed to him the wonders of combat training and heroism, fighting with less advanced for that period “Messerschmitts” and “Junkers”. Not to be unfounded, I will give just a few examples of military work of the 163rd fighter regiment.
The young pilot Lieutenant Akhmetov in one of the first days of the war clashed with 15 enemy bombers before they bombed precisely.
Six-16, led by senior Lieutenant Plotnikov, collapsed on 26 enemy fighters. Destroying six cars, our pilots without loss returned to their base. By 4 July the pilots of the 163rd regiment destroyed 21 enemy aircraft, and it’s outdated machines.
Especially good in the fight against the German bombers were “donkeys” armed with two 20-millimeter guns. I-16 can be, without exaggeration, be attributed to the number of aircraft long-lived. Suffice it to say that these machines fought until 1944. In particular, the 3rd fighter squadron of the air force of the Baltic fleet was reequipped with a-16 to a more modern Yak-7 in February 1944 and joined the 21st regiment. And in the far East part of the armed I-16, he participated in the war with Japan.
Planes I-16 And the motors M-62 and M-63 was withdrawn from the aviation, defense and decommissioned in accordance with the decision of the Military Council of the air force and the Directive of the chief engineer of air defense fighter aircraft from November 20, 1945. The same thing happened with cars belonging to naval aviation and the air force.
Once is not called a fighter. In Spain, for example, nationalists, he was nicknamed “rata” (“rat”), and the Republicans – “Mosca” (“fly”). But for us he remains obstinate, the past is not one war, “the one”.

In the summer of 1932 on the initiative of H. H. Polikarpov, who worked at the Central design Bureau began development of a promising fighter-monoplane with retractable landing gear. In may next year, the BBC confirmed their interest in the car and gave Polikarpov for the task. Six months later, the client approved the layout of the aircraft, designated the TSKB-12, and in the same month, the Council of labor and defense (STO) of the USSR adopted a decision on starting the machine received the designation I-16, in serial production.
