The He 274 V2 was eventually completed as the AAS 01B, complete with the Hirth 2291 turbochargers. Work began on the He 274 in 1941, under the designation He 177H. The Heinkel He 274 was a high altitude bomber developed from the Heinkel He 177, the heaviest bomber to see regular service with the Luftwaffe during the Second World War. O Heinkel He 274 foi um bombardeiro pesado alemão quadrimotor [1] criado pela Heinkel, na Alemanha, durante a Segunda Guerra Mundial.Foi concebido para voar a altas altitudes, aspecto que fazia dele um bombardeiro com fuselagem pressurizada. The Heinkel He 274 was a German heavy bomber design developed during World War II, purpose-designed for high-altitude bombing with pressurized crew accommodation. Due to the Allied advance through Northwest Europe, the prototypes were … [11] Both of the AAS 01 completed and airworthy versions of the He 274 were eventually broken up in late 1953, after serving as "mother ships" for aerial launching, in the manner of a composite or parasite aircraft, of a number of early French advanced jet and rocket test aircraft like the unpowered Sud-Ouest SO.4000 M.1, almost always launched from a strut-braced, above-fuselage position. Max takeoff weight:44,500 kg (98,105 lb) 8. The Heinkel He 274 was a German heavy bomber design developed during World War II, purpose-designed for high-altitude bombing with pressurized crew accommodation. In February 1943, any further work on the coupled-engined A-2 and A-4 designs was halted by order of the RLM, as the four-engined He 177H high-altitude design had gained in importance from that time, evidenced by Reichsmarschall Hermann Göring's derisive "welded-together engines" complaints in August 1942, regarding the He 177 A-series unending engine problems from the choice of the DB 606 and 610 "power systems" for the A-series operational aircraft. Authored By: Staff Writer | Last Edited: The straight-edged mainplanes were set ahead of midships, noticeably tapering towards their tips, and each held leading edge-installed engine nacelles. Wingspan:40.00 m (131 ft 3 in) 4. The Heinkel He 274-page contains all related products, articles, books, walkarounds and plastic scale modeling projects dedicated to this aircraft.. The Heinkel firm had been working on practical cockpit pressurization methods and hardware for both the A-2, and slightly later A-4 versions (identical to the A-2, except for the fitting of a pair of the later DB 610 coupled engine "power systems") from 1940 through the late summer of 1941, when the DB 610-powered A-4's pressurized cockpit in provisional form, almost identical in external appearance to the standard "Cabin 3" He 177A-series production cockpit, was ready for tests and development. The Heinkel He 274 was a German Luftwaffe heavy bomber developed during World War II, purpose-designed for high-altitude bombing with pressurized crew accommodation. Heinkel He 274 V-1 (Q6U9Z9G67) by wwwitalik on Shapeways. * Ribbons not necessarily indicative of actual historical campaign ribbons. This frustrated completion of the French prototypes as the design work in Germany and Austria had been ongoing from as early as February 1943, on what had emerged as the Heinkel-designed entry in the trans-Atlantic range Amerika Bomber strategic heavy bomber design competition, the Heinkel He 277, had been progressing at the Heinkel-Sud facility in Vienna, which had been cancelled by the German Air Ministry back in April 1944. Variants: Heinkel He 277. The result, in December 1940, was the specification for the He 177A-2 high altitude bomber design, with a four-person crew manifest (pilot, bombardier, forward gunner and tail gunner) in the two specified pressurized compartments, and powered by the regular A-series pair of DB 606 coupled engines. This topic is categorised under: Aircraft » Propeller » Heinkel He 274 The Heinkel He 274 was a German heavy bomber design developed during World War II, purpose-designed for high-altitude bombing with pressurized crew accommodation. [2] Heinkel had foreseen that an individually engined version of his bomber would someday be preferred, quite unlike the requested fitment of the coupled pairs of Daimler-Benz DB 601 inverted V12 engines, each known as a DB 606 — weighing some 1.5 tonnes apiece — which ended up being fitted to all of the eight He 177 V-series prototypes at the request of the RLM, and the Luftwaffe High Command, with the concerned government agencies citing the desire for a dive-bombing capability to be present even with a heavy-bomber-sized offensive warplane, something Ernst Heinkel vehemently disagreed with. The He 274 V1 was being readied for flight testing at Suresnes in July 1944 when the approach of Allied forces necessitated the evacuation of Heinkel personnel working on the project. Main production series, 826 built. He 177 ancestry. French production facilities at Toulouse for Heinkel aircraft were severely damaged by Royal Air Force(RAF) air raids on the night of 5/6 March 1944 and again by the US Eighth Air Force on 25 June 1944. Originally designated He 177 A-4, the He 274 was a high-altitude development of the He 177. Work on the requested half-dozen He 274 prototype airframes was leveraged off Heinkel aircraft production at AIA Breuget, Toulouse where French factories produced Heinkel components and Junkers aero engines. [3] The aircraft was intended to have a reduced crew manifest of three people, with a fully pressurized nose compartment for the pilot and bombardier/forward gunner, and separate pressurized tail gun emplacement.
