These blimps were well suited for those missions because they could remain aloft, unrefueled for long periods of time.In March 1957 an N class airship model ZPG-2 nicknamed The N Class airships had two Cyclone 7s mounted in an engine room within the control car. It was developed from the larger twin-row Wright R-2600. Wright R-1300 in Jeju Aerospace Museum 20140606-01.JPG 2,400 × 4,240; 1.28 MB. The Wright R-1300 Cyclone 7 is an American air-cooled seven-cylinder supercharged radial aircraft engine produced by Curtiss-Wright. Lycoming Division, AVCO Manufacturing Corp. of Stratford, Connecticut began Cyclone 7 production in 1955. A new design was launched in 1926, known as the R-1750 Cyclone. Cylinders had a bore of 6.125". Wright Aeronautical chose violent windstorms for their engine names: Whirlwind, Tornado, Cyclone, and Typhoon.The Wright Cyclone 7 was Wright’s smallest in a long line of Wright radial aircraft engines named “Cyclone.” The other Cyclones were the R-1750 and R-1820 Cyclone 9, the R-2600 Cyclone 14, R-3350 Duplex Cyclone.
