S-2 – airplane-Sturmovik

In the late 1920s,. Scientific and Technical Committee of the Office of the Air Force proposed requirements for ground-attack aircraft. Armed with two types of attack aircraft were to be: heavy and light. Heavy attack TS-B was designed to destroy ground targets are well protected on the battlefield, LS and light against the marching columns of infantry and cavalry of the enemy. TS-B was designed under the guidance in TsAGI AN. Tupolev, a CL - N, N. Polikarpov. In April 1930 g. N, N-. Polikarpov was ordered to the design of the LS light attack and almost at the same time to create a heavy bomber. In that year, NN KB. Polikarpov and it was uploaded, engaged in both the design, testing and development of several different machines. Polikarpov I already had experience designing aircraft OL-1 "Action" and assault modifications reconnaissance P-1 and P-5.

LS scheme was selected by the type of plane P-5. Offensive Armament consisted of four machine guns moving, installed in the fuselage inclined shaft down. For protection against enemy air attack aircraft was back firing point. Armor closed the engine and the crew only from below. Already in the process of designing the plane converted into a heavy attack TS-1. His nose portion is in the form bronekorobki, wherein the engine hosted, water- and oil cooler, gas tanks, cockpit and arrow. Bronekorobka collected from separate flat or curved pieces of armor, which gave the aircraft angular view, worsening its aerodynamics. All this complicates the full armor included in the power circuit of the aircraft and increases its mass. The armament was strengthened, six machine guns added two more.
Since the summer 1930 g. All work on the attack aircraft carried out under the guidance of designer SA. Kocherigina. 10 July 1930 g. It was created to eliminate sabotage Commission factory number 39 (It is also called the Commission on cleaning personnel). Under the clean hit and NN. Polikarpov. The Commission has received a number of letters, revealing his "criminal activity". In addition, in August he crashed pilot NII VVS kökar his plane D-2. All this was the reason for the removal of NN. Polikarpov from his post and transfer him to the post of senior engineer on settlements.

The first pre-attack TS-1 with the engine M-17 was prepared in the beginning 1931 g. In January, it began flight tests, which revealed some problems in the engine cooling system. Many of the comments to the TS-1 structure taken into account in the construction of an improved variant thereof TS-2 with the BMW engine-VI. aircraft testing showed relatively low flight - maximum speed does not exceed 215 kmh. Most armor weight limited combat capabilities of these storm troopers: They were equipped with only small arms, bomb armament had. Eleven TS-2 has been released.
In April of the same year it was built another torpedo attack SEAN (attack special purpose). The history of its creation is: at the end 1927 g. there was a proposal to convert a training ship "Komsomolets" aircraft carrier. He had to carry out on board Air Group 26 fighters and 16 stormtroopers. For him, and was designed by SEAN attack - torpedo carrier. Plane for easy storage on the ship had folding wings. Tests have shown satisfactory results. The series did not run, since build carrier did not need and disappeared in a similar plane.
