Right R-2600 Cyclone 14 (также называемый Twin Cyclone )-это американский радиальный двигатель, разработанный Curtiss-Wright и широко используемый в самолетах в 1930-х и 1940-х годах.
История
[ редактировать ]В 1935 году Curtiss-Wright начал работать над более мощной версией их успешного R-1820 Cyclone 9 . Результатом стал близнечный циклон R-2600 с 14 цилиндрами, расположенными в двух рядах. Компания кВт (1200 ) R- 2600-3 ; 1600 пс R-2600-3 было первоначально предназначено для коммандос C-46 . Это был также оригинальный выбор двигателя для F6F Hellcat ; Занимая изменение (одно, которое не остановит производство) для CW-20A, и одно в конце апреля 1942 года для второго XF6F-1, привело к принятию 2000 л.с. (1500 кВт; 2000 пс). Pratt & Whitney R- 2800 двойная оса в месте R-2600 для обоих дизайнов.
The Twin Cyclone went on to power several important American World War II aircraft, including the A-20 Havoc, B-25 Mitchell, TBF Avenger, SB2C Helldiver, and the PBM Mariner.
Over 50,000 R-2600s were built at plants in Paterson, New Jersey, and Cincinnati, Ohio.
Variants
[edit]- R-2600-1 - 1,600 hp (1,194 kW)
- R-2600-2 - 1,500 hp (1,118 kW)- Prototype variant; Few were made.[2]
- R-2600-3 - 1,600 hp (1,194 kW)
- R-2600-4 - 1,650 hp (1,230 kW)[3]
- R-2600-6 - 1,600 hp (1,194 kW)
- R-2600-8 - 1,700 hp (1,268 kW)
- R-2600-9 - 1,700 hp (1,268 kW)
- R-2600-10 - 1,700 hp (1,268 kW)- Experimental high-altitude R-2600 variant with a two-stage mechanical supercharger, vs the usual single-stage supercharger. The 2600-10 also served as a testbed for turbo-supercharging the 2600 series. Very few were produced.[4][5]
- R-2600-11 - 1,600 hp (1,194 kW)[6]
- R-2600-12 - 1,700 hp (1,268 kW)
- R-2600-13 - 1,700 hp (1,268 kW)
- R-2600-14 - 1,700 hp (1,268 kW)- One of the engines which powered Grumman's prototype F6Fs, the XF6F-1 (the two-stage supercharged R-2600-10 was also tested in the XF6F-1). Grumman was not happy with the performance, which led to the 2,000 hp Pratt & Whitney R-2800 engine replacing the R-2600 on F6F production models.[7]
- R-2600-15 - 1,800 hp (1,342 kW)- Planned to power the XB-33A, a prototype model of the B-33 Super Marauder (itself a high-altitude version of the B-26 Marauder). The project was cancelled, and neither the prototype XB-33A or production B-33A were ever built.[8]
- R-2600-16 - 1,700 hp (1,268 kW)- Similar to the R-2600-10 & -14, the -16 powered a Grumman prototype F6F, the XF6F-2.[9]
- R-2600-19 - 1,600 hp (1,194 kW), 1,660 hp (1,237 kW)
- R-2600-20 - 1,700 hp (1,268 kW), 1,900 hp (1,420 kW)
- R-2600-22 - 1,900 hp (1,420 kW)
- R-2600-23 - 1,600 hp (1,194 kW)
- R-2600-29 - 1,700 hp (1,268 kW), 1,850 hp (1,380 kW)
- GR-2600-A5B - 1,500 hp (1,118 kW), 1,600 hp (1,194 kW), 1,700 hp (1,268 kW)
- GR-2600-A71 - 1,300 hp (969 kW)
- GR-2600-C14 - 1,750 hp (1,304 kW)
