| dbo:abstract | Wright R-3350 Duplex Cyclone byl letecký motor, vzduchem chlazený dvouhvězdicový osmnáctiválec, vyvíjený firmou ve druhé polovině 30. let. Nejznámější je jeho použití na těžkých čtyřmotorových bombardérech Boeing B-29 Superfortress, po válce byl používán mj. na dopravních letounech Lockheed Constellation a Douglas DC-7. Nedostatečné chlazení válců zadní hvězdice u B-29 mohlo vést i k samovznícení motoru za letu. Vzhledem k použití hořčíku v některých komponentách motoru pak zpravidla (v 87 % zaznamenaných požárů) palubní hasicí systém na uhašení nestačil, což mohlo vést až ke zřícení letounu. Druhý prototyp XB-29 dokázal 30. prosince 1942 přistát s hořícím motorem, ale 18. února 1943 se mu další požár za letu stal osudným. V roce 1943 se problémy ve výrobě tohoto motoru zabývala senátní komise (oficiálně Senate Special Committee to Investigate the National Defense Program), kterou vedl Harry S. Truman.

Era un motor radial de 18 cilindros en doble fila, sobrealimentado y refrigerado por aire. La potencia que ofrecía variaba entre los 2200 y 3.700 hp (1.640 a 2.760 kW), dependiendo del modelo. Su desarrollo comenzó antes de la Segunda Guerra Mundial, pero el diseño requirió mucho tiempo para madurar y finalmente ser empleado para propulsar el bombardero estratégico Boeing B-29 Superfortress. (es) Le Wright R-3350 Duplex Cyclone est l'un des plus puissants moteurs en étoile destinés à l'aviation produits aux États-Unis. Il est composé de deux blocs de 9 cylindres disposés l'un derrière l'autre en double étoile (double wasp), soit un total de 18 cylindres. Le moteur est refroidi par air et compressé mécaniquement. Il développe une puissance allant de 2 200 à plus de 3 700 ch (1 640 à 2 760 kW), selon les versions. Entamée avant la Seconde Guerre mondiale, la conception du R-3350 demande longtemps pour arriver à maturité, avant que le moteur soit finalement utilisé pour équiper le Boeing B-29 Superfortress. Parmi les appareils les plus connus équipés de ce moteur, on peut citer également le bombardier d'appui tactique Douglas A-1 Skyraider. Après la guerre, le moteur a suffisamment évolué pour équiper également de nombreux avions de transport civils, notamment dans ses formes Turbo-Compound. Parmi les plus connus, toute la gamme des Constellation de chez Lockheed s'en verra équipée. De nos jours, ces moteurs, reconditionnés à neuf, sont souvent utilisés pour motoriser les Hawker Sea Fury restaurés en remplacement du moteur d'origine Bristol Centaurus, moins fiable et aux pièces plus difficilement trouvables. Il équipe ainsi plusieurs Hawker Sea Fury engagés dans la course aérienne de Reno, catégorie Unlimited. Il équipe également, en remplacement du Pratt & Whitney R-2800 originel, Rare Bear, un autre Reno Racer sur base de Grumman Bearcat, crédité de plusieurs records de vitesse. Le numéro de ce moteur (3350) indiquant la cylindrée de 3 350 cubic inch (ou pouces cubes), soit 54,86 L. Deux moteurs R 33560-32WA de Neptune P-2V découpés pour instruction, sont conservés au Musée de l'Aéronautique navale de Rochefort et au musée de tradition de la BAN Lann Bihoué. (fr) ライト R-3350 サイクロン 18（Wright R-3350 Cyclone 18）は、アメリカのカーチス・ライトによって開発・製造された航空機用空冷星型エンジン。通称デュプレックスサイクロン（Duplex Cyclone =二重のサイクロン）エンジンとも呼ばれる。B-29戦略爆撃機に搭載され、対日戦に非常に大きな役割を果たした。このエンジンは、当時の航空機用レシプロエンジンとしては、最大規模の出力を誇る。しかし、その分開発も非常に難航し、開発自体は第二次世界大戦の開戦以前から開始されていたが、大戦時にB-29に採用されるまでには長い期間が必要であった。戦後は民間旅客機のエンジンとして、ターボコンパウンド仕様のエンジンが製造されたが、こちらは信頼性に欠け、不評であった。 (ja) The Wright R-3350 Duplex-Cyclone is an American twin-row, supercharged, air-cooled, radial aircraft engine with 18 cylinders displacing nearly 3,350 cubic inches (54.9 L). Power ranged from 2,200 to over 3,700 hp (1,640 to 2,760 kW), depending on the model. Developed before World War II, the R-3350's design required a long time to mature before finally being used to power the Boeing B-29 Superfortress. After the war, the engine had matured sufficiently to become a major civilian airliner design, notably in its turbo-compound forms, and was used in the Lockheed L-1049 Super Constellation airliners into the 1990s. The engine is commonly used on Hawker Sea Fury and Grumman F8F Bearcat Unlimited Class Racers at the Reno Air Races. Its main rival was the 4,360 in3 (71.4 L), 4,300 hp (3,200 kW) Pratt & Whitney R-4360 Wasp Major, first run some seven years after the Duplex-Cyclone's beginnings. (en) Il Wright R-3350 Duplex Cyclone era un motore aeronautico radiale 18 cilindri a doppia stella raffreddato ad aria, prodotto negli anni quaranta dall'azienda statunitense Curtiss-Wright Corporation. Il Duplex Cyclone è stato uno dei più potenti motori radiali prodotti negli Stati Uniti. Il suo sviluppo iniziò prima dello scoppio della seconda guerra mondiale, ma il motore richiese un lungo periodo di maturazione prima di venire utilizzato sul bombardiere Boeing B-29 Superfortress, poco prima della fine del conflitto. Dopo la guerra il motore era sufficientemente maturo tanto da divenire il principale motore usato nei progetti di velivoli civili, particolarmente nella sua versione Turbo-compound. La sigla R-3350 identifica il modello in base alla sua cilindrata in pollici cubici, circa 3 350 in³ (it) |
