Air-cooled radial engines such as the Wright Cyclone and Pratt & Whitney Wasp became the standards for naval aircraft. Their advantages also appealed to designers of commercial air transports. With few exceptions, commercial air transports throughout the world relied on air-cooled radial engines until the advent of jet engines.
This R-1820-97 was manufactured under license by Studebaker. A total of 64,093 R-1820-97 engines were built between July 1942 and October 1943, more than any other model in the R-1820 series. The -97 powered the Boeing B-17E/F/G, Douglas B17F-DL/-19G-DL, Vega B17F-VE/17G-VE, and Northrop N-1-25A.
One by one each aircraft started and taxied to runway two eight for departure. First the B-17G, Nine O Nine taxied on Alpha to the hold short at two eight. I heard the call on the radio and then the Wright Cyclones roared to life, she was on the roll.
Next up was the Collings Foundation P-51C, Mustang, Betty Jane. Make no mistake this Mustang made some noise as the 1300 hp Packard Merlin V-1650-7 flexed it's muscle.
I did manage a short video as the P51 made a low pass before departing to the north. I'm working on getting that posted.
Next up the B24J, Witchcraft. This isIf only every work day could be so much fun. Back to reality and my meeting followed by an hour and a half ride back to the office. At least I had a smile on my face all day!
the ONLY one of the only TWO B24 aircraft still flying. The four 1200 hp Pratt and Whitney R-1830-65 Engines rumbled as she taxied for departure. With a call on CTAF the engines came up to power and the B24 was rolling. I Love the sound of the radials and watching them from the grass alongside the runway was awesome.
