The Wright R-975 Whirlwind was a series of nine-cylinder air-cooled radial aircraft engines built by the Wright Aeronautical division of Curtiss-Wright. These engines had a displacement of about 975 cu in (15.98 L) and power ratings of 300–450 hp (220–340 kW). They were the largest members of the Wright Whirlwind engine family to be produced commercially, and they were also the most numerous.

  • صنعت محرك أر-975 بموجب ترخيص للاستخدام في دبابات الحلفاء و العربات المدرعة خلال الحرب العالمية الثانية. صُنعت عشرات الآلاف من المحركات لهذا الغرض، مما أدى إلى تقليص استخدامها في الطائرات. استمرت كونتينينتال في إنتاج طرازاتها الخاصة من محرك أر-975 بعد الحرب في خمسينيات القرن العشرين. أُنتجت بعض هذه المحركات بقدرة بلغت 550 حصاناً (410 كيلو وات). اكتسب محرك أر-975 شهرة كبيرة لاستخدامه كمحرك لقانصة الدبابات ، التي كانت أسرع وأفضل قانصة دبابات أمريكية في الحرب العالمية الثانية. ظلت إم 18 المشغلة بمحرك أر-975 أسرع مركبة مدرعة في العالم حتى ظهور إم 1 أبرامز المشغلة بواسطة تربينة في الثمانينيات من القرن العشرين.

  • Wright R-975 Whirlwind ist eine Baureihe von luftgekühlten Neunzylindersternmotoren für Flugzeuge, die von der Sparte Wright Aeronautical des US-amerikanischen Unternehmens Curtiss-Wright gebaut wurde. Die Motoren haben einen Hubraum von rund sechzehn Litern und Leistungen zwischen 300 PS (221 kW) und 450 PS (331 kW). Sie sind die größten, in Serie gebauten Modelle der Motorenfamilie Wright Whirlwind und wurden am zahlreichsten gebaut. Während des Zweiten Weltkriegs baute Continental Motors den R-975 in Lizenz als Antrieb für die Panzer der Alliierten und andere gepanzerte Fahrzeuge. Für diesen Zweck wurden tausende Einheiten hergestellt, was den Einsatz des R-975 in der Luftfahrt praktisch in der Bedeutungslosigkeit versinken ließ und von dem ähnlichen Pratt & Whitney R-985 in den Schatten gestellt wurde. Nach dem Krieg baute Continental bis in die 1950er Jahre seine eigene Version des R-975. Manche dieser Triebwerke leisteten bis zu 550 PS (405 kW). Der R-975 wurde als Triebwerk für den US-amerikanischen Jagdpanzer M18 Hellcat im Zweiten Weltkrieg eingesetzt. Der M18 war das schnellste gepanzerte Kettenfahrzeug bis zur Einführung des turbinengetriebenen M1 Abrams in den 1980er Jahren. (de)

They were the largest members of the Wright Whirlwind engine family to be produced commercially, and they were also the most numerous. During World War II, Continental Motors built the R-975 under license as a powerplant for Allied tanks and other armored vehicles. Tens of thousands of engines were built for this purpose, dwarfing the R-975's usage in aircraft, where it was overshadowed by the similar Pratt & Whitney R-985. After the war, Continental continued to produce its own versions of the R-975 into the 1950s. Some of these produced as much as 550 hp (410 kW). The R-975 powered the American World War II M18 Hellcat tank destroyer which was claimed to have been the fastest tracked armored vehicle until the introduction of the turbine powered M1 Abrams in the 1980s.

  • Il Wright R-975 Whirlwind era un motore aeronautico radiale a 9 cilindri a singola stella raffreddato ad aria, prodotto negli anni quaranta dalle aziende statunitensi Curtiss-Wright Corporation e . Modello dalla maggiore potenza disponibile tra quelli appartenenti alla famiglia Whirlwind avviati alla produzione in serie, venne utilizzato sia in campo aeronautico (ne furono costruite oltre 7 000 unità fino al 1945) che come equipaggiamento di mezzi corazzati terrestri, nella versione prodotta su licenza dalla Continental Motors. La sigla R-975 identifica il modello in base alla sua cilindrata in pollici cubici, 975 in³ corrispondenti a circa 16 litri. (it)
