DIS Layout Drawing

DIS. In the spring of 1945, the design bureau of plant No. 482 began designing a long-range escort fighter (DIS) based on the recently tested Pe-2I dive bomber. Note that both pilots, the pilot and the navigator were in the same cockpit and sat back to back with the possibility of turning the latter.

Armament. A characteristic feature of this aircraft was a very powerful offensive weaponry. In the nose of the fuselage, two (one) B-20 cannons were installed, fixed in a stationary position, and at the bottom of the hull, in a thickening made on the Pe-2I for the suspension of a protruding one-ton bomb, two more cannons of 37 mm caliber, or 45 mm and even two 57 mm guns. For ammunition, respectively, 250 shells, 200 shells and, finally, 175 shells each, it was determined quite enough space in the aircraft body. The mass of a second salvo ranged from 12.3 kg to 17.8 kg. The navigator had one more short-barreled cannon installed on the turret by M.E. Berezina BT-20 for protection from the rear hemisphere.

Construction. All-metal, like all previous "Pawns", especially like the Pe-2I. The innovations were anti-icers on all important components of the aircraft. Due to the tips, the wingspan was slightly increased. The engines were installed in the same places, but with a radically changed cooling system. So, water radiators were placed in the developed wing center section. The oil coolers, along with the air intakes of the carburetors, were spaced out on the outer sides of the engines to the extent limited by the propellers. Engines VK-107 differed from VK-105 in two upper rows of exhaust pipes. Four rows of exhausts were required by the minders due to the extreme increase in the temperature regimes of the VK-107 compared to the VK-105 engine.

Construction of the aircraft began on July 15 and was completed by November 2, 1945. Everywhere the plan was overfulfilled, and the simplified assembly technology contributed to the acceleration of assembly and assembly work in all shops of the enterprise under construction. Recall that V.M. Myasishchev was evacuated to Kazan in 1942 and replaced the chief designer A.I. Putilov, who worked on the Pe-2 series. After the death of V.M. Petlyakov, his place was temporarily taken by A.M. Isakson, continuing to lead the dive bomber series. When he ceased to cope with the frantic pace of work, he was dismissed and appointed the next successor to A.I. Petlyakov. Putilov, whom A.N. Tupolev, recommending Myasishchev in his place. From Kazan, where at the 22 plant Myasishchev still managed to achieve the required performance in the production of "Peshek", his design bureau was re-evacuated to Moscow, where a small area of ​​the former plant No. 133 was allocated to designers and production workers. This fenced patch on Khodynka was named the plant No. 482. The design, model work and construction of future Myasishchev's aircraft began in parallel with the rebuilding of new high-quality hulls intended for the design bureau, laboratories, workshops and other factory services.

It is known that the fine-tuning of the M-107 engines on his I-110 aircraft in the sharaga of plant No. 288 in Omsk was carried out by D.L. Tomashevich. By 1944, he managed to do this at the expense of powerful oil and water radiator groups. Then motors of this type went to experienced Pawns ...

At the end of 1945, the Myasishchevsky DIS entered flight tests, but the end of the war and the transition to jet technology determined the fate of the aircraft, which remained in a single copy.
