Heinkel He 177-277-274, Airlife Publishing, Shrewsbury, England 1998, pp. [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. Heinkel He 274 je bil štirimotorni propelerski težki bombnik, ki so ga razvili v nacistični Nemčiji med 2. svetovno vojno. On 17 November 1938, the owner of the Heinkel aviation firm, Ernst Heinkel, requested permission from the RLM that two of the requested eight prototype airframes for the nascent He 177 heavy bomber project, specifically the V3 and V4 airframes, be set aside for a trial installation of four separate Junkers Jumo 211[1] powerplants. Self-defensive armament constituted a pair of remotely-operated turrets, one fitted dorsally and the other ventrally, and each was to be armed through 2 x 13mm MG131 machine guns. Bombnike so sestavljali Franciji, vendar jih zaradi zavezniškega napredovanja niso dokončali. Only minor damage was actually done to the airframe of the He 274 V1, and repairs were begun after the Allied occupation. 3 people found this helpful Zgrajena sta bila samo dva prototipa. Due to the Allied advance through North-west Europe, the prototypes were abandoned at … Due to the Allied advance through North-west Europe, the prototypes were abandoned at the French factory where they were being built. Eine luftfahrtgeschichtliche Dokumentation. 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. The He 274 also featured a pressurized compartment for a crew of four, this employing double walls of heavy-gauge alloy, hollow sandwich-type glazing and inflatable rubber seals, a pressure equivalent to that at 2,500 m (8,200 ft) being maintained at high altitude. 7. [4] The A-2 version had even been considered for a pioneering in-flight refueling capability, possibly using Ju 290 maritime patrol aircraft as the tankers - with such capability, the range of the A-2 would have been extendable to some 9,500 km (5,900 mi) of total flight distance. The newsfeed doesn't contain any items. By October 1941, a more developed "He 177H" specification for a high-altitude Heinkel-designed heavy bomber[6] had emerged from the proposed A-2 and A-4 coupled-engine designs, with the intent of carrying a 2,000 kg (4,410 lb) bombload over a maximum range of some 3,000 km (1,895 mi), and accepted by the RLM for the first time, an individual four-engine installation was being considered for any He 177-based bomber airframe, with a quartet of either BMW 801 or DB 603 engines among the choices of powerplants being specified, with the same sort of reduced-armament defensive weapon format as the A-2 and A-4 were intended to have. Heinkel He 177-277-274, Airlife Publishing, Shrewsbury, England 1998. Length:23.00 m (75 ft 5 in) 3. 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. Standardized on the A-3's longer rear fuselage, strengthened wing, shortened undercarriage oleo legs, ETC 2000/XII wing racks and an increase in maximum external load. Two He 274 prototypes were ordered built in France by the Farman Brothers and four pre-production prototypes by the Heinkel's Heinkel-Nord headquarters at its Rostock-Marienehe (today's Rostock-Schmarl) facility. Due to the bombers expected high-altitude traveling, it was decided to limit gun/cannon armament. The new version was soon entering production, with the first bomber squadron operational in May 1944, just before D-Day. These proposed aircraft were shortly thereafter officially given the project number 8-274 by the RLM, and due to the heavily preoccupied Heinkel factory design offices and aircraft manufacturing facilities, this new "He 274" high-altitude bomber was to have its prototypes built in France by the Societe des Usines Farman (Farman Brothers) in Suresnes. [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. ISBN 1-85310-364-0. Work began on the He 274 in 1941, under the designation He 177H. The Heinkel He 219 Uhu ("Eagle-Owl") is a night fighter that served with the German Luftwaffe in the later stages of World War II.A relatively sophisticated design, the He 219 possessed a variety of innovations, including Lichtenstein SN-2 advanced VHF-band intercept radar, also used on the Ju 88G and Bf 110G night fighters. Při rychlém spojeneckém postupu přes severozápadní Evropu po vylodění v Normandii zůstaly prototypy ve francouzské továrně, kde byly postaveny.

The Heinkel He 274 was a four-engine bomber designed during World War II as a high altitude variant of the Heinkel He 177 for the German Luftwaffe . Wingspan:40.00 m (131 ft 3 in) 4. Largely unnecessary defensive armament was restricted to a single forward-firing 13 mm (.51 in) caliber MG 131 machine gun and remotely controlled dorsal and ventral Fernbedienbare Drehlafette FDL 131Z gun turrets each containing a pair of MG 131s and with the dorsal turret operated from a slightly offset Plexiglas domed sighting station in the roof of the flight deck as most A-series He 177s were, with the ventral unit aimed from the rear of the ventral Bola gondola. Heinkel He 177: Variants Heinkel He 274: The Heinkel He 277 was a four-engine, long-range heavy bomber design, originating as a derivative of the He 177, intended for production and use by the German Luftwaffe during World War II. Due to the Allied advance through North-west Europe, the prototypes were abandoned at … 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. [7], A pair of the early He 177A-0 pre-production prototypes were redesignated the He 177 V10 and V11 for the purposes of high-altitude trials, and were to be the first to test the A-4 pattern pressurized cockpit design at altitude, but only the V11 was actively used for the needed research, and managed to achieve an altitude of 9,200 m (30,200 ft) with complete success on August 9, 1943, with further tests continuing through October of that year, before both the V10 and V11 were grounded in April 1944.[8].

Construction of the two prototypes, the He 274 V1 and V2 did not commence until 1943. [5] 159 & 184. The "Typenblatt" drawings for the never-completed He 277, with a heavy design influence for the fuselage's geometry from the smaller Heinkel He 219 night fighter, however show[10] that it had also adopted many features from the He 274, especially its twin tail empennage design. 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. Originally designated He 177 A-4, the He 274 was a high-altitude development of the He 177. [13] The slightly less powerful, French designed four-engined SNCASE SE.161 Languedoc airliner design took over this "mother ship" role later in the 1950s, for further air launch duties with French high-speed aerodynamic research prototypes. Heinkel He 177 - 277 - 274. The He 274 V2 was eventually completed as the AAS 01B, complete with the Hirth 2291 turbochargers. Learn more before you buy, or discover other cool products in Aircraft.
