Under the direction of Andrei Tupolev, Soviet engineers undertook one of the most ambitious reverse-engineering programs in aviation history, converting every imperial measurement to metric, substituting Soviet materials and manufacturing standards, and replacing the American powerplant with indigenous Soviet engines. The result was an aircraft that looked identical to the B-29 but was, in engineering terms, a distinctly Soviet machine.\u003c\/p\u003e\u003cp\u003eThis collection brings together \u003cstrong\u003efour original Soviet factory technical manuals\u003c\/strong\u003e issued between 1949 and 1953 by the State Publishing House of the Defense Industry (\u003cem\u003eГосударственное Издательство Оборонной Промышленности \/ Оборонгиз\u003c\/em\u003e), covering the full technical description of the Tu-4 across its service life.\u003c\/p\u003e\u003chr\u003e\u003ch3\u003e✈️ Aerodynamic Profile \u0026amp; Structural Engineering\u003c\/h3\u003e\u003cp\u003eWhile the Tu-4 was visually indistinguishable from the B-29, its structural and aerodynamic profile carried unique Soviet engineering signatures:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe Metric Conversion:\u003c\/strong\u003e Every dimension was converted from imperial to metric, altering aluminum skin thicknesses and producing a slightly stiffer, marginally heavier airframe.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWing Geometry:\u003c\/strong\u003e High-aspect-ratio straight wing retained at \u003cstrong\u003eAR 11.5\u003c\/strong\u003e, optimized for long-range, high-altitude cruise performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight Profile:\u003c\/strong\u003e Empty weight increased to \u003cstrong\u003e36,850 kg\u003c\/strong\u003e — approximately 1% heavier than the B-29 — with wing loading adjusted to \u003cstrong\u003e400 kg\/m²\u003c\/strong\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\u003chr\u003e\u003ch3\u003e⚙️ Powerplant — Shvetsov ASh-73TK\u003c\/h3\u003e\u003cp\u003eThe most significant mechanical departure from the B-29 was the powerplant.
