Hi! "Deck-mounted torpedo 509

"In the USSR the question of deck aircraft took quite distinct forms in the late forties, when it adopted an ambitious programme to establish Ocean fleet. It provided for the construction of aircraft carriers and various classes. At the same time aviation KB got jobs on design of deck aircraft. Fighters engaged in collective A.s. Yakovlev, bombers and ground attack aircraft-A.n. Tupolev.
In 1950 year A.n. Tupolev OKB received an assignment to investigate the possibility of creating a deck torpedo bomber with two engines VC-1 with the following data:
-maximum take-off weight-15 t;-maximum speed at an altitude of 5000 m-900 km/h;-ceiling-12000 m;-range with 1500 kg of bombs-1500 km;
-takeoff with 2 accelerators for an aircraft carrier in 20 nodes-220 m;-envelope with folded wing scale-8 m;-aircraft length-15 m;-height-6 m;
-gun armament:forward 2 guns;back to the KDU-2 guns;-caliber guns-23 mm;
-the crew-2 pers.
Conceptual design and production of drawings were completed by 1953 g.
Draft deck torpedo-bomber "509 (9th draft 1950 г.) was created on the base of 81 aircraft (NAVY torpedo bomber TU-14) with a reduction in all options over about a third ... The desire to use this machine as a prototype, it was understandable and natural. Its layout and the technical solutions adopted, as demonstrated by flight tests (1947-49), were acquitted. The powerplant was supposed to be two VK-1 TURBOJET ENGINE with a centrifugal compressor. The main difference were folding wing and brake for planting with ajerofinisherom GAK.
Study showed that the job has the ability to meet the defined dimensions and provide the required information when the takeoff weight 13-15 tons and wing surface 50-60 sq.m. For further calculations you selected with takeoff weight 14.8 tons and wing area 54 sq.m. Certain difficulties were associated with the size of the KDU and sighting radar PRS-1 "Argon".
All performance data was feasible except for the length of the take-off decks at 220 m, which could only be achieved using 4-x.
"509" Project was brought to the stage technical proposal with two variants of the nose of the fuselage (from 81 aircraft or aircraft 82 "), with a wingspan 18.2 m, wing area of 55 sq m, extension wing-6, takeoff weight 15 t and bomb load of up to 3000 kg."
