Curtiss OX-5 V-8 Engine
Curtiss manufactured more than 10,000 OX-5 V-8s during World War I, mostly for Curtiss JN-4 Jenny military trainers. After the war, the U.S. government sold thousands of surplus OX-5s and Jennys to the public at a fraction of their original cost. The availability of a well-proven, inexpensive engine in such quantity was a mixed blessing. It enabled many people of modest means to fly, but manufacturers of more modern power plants suffered.
The OX-5 was a mainstay for barnstormers, private pilots, and aircraft designers in the United States in the 1920s and ’30s. Besides the Jenny, the OX-5 also powered many new civil aircraft manufactured by Alexander, Curtiss, Fairchild, Laird, Travel Air, Waco, and others. This OX-5 was removed from a Curtiss JN-4D that suffered a landing accident near Greensboro, North Carolina, about 1921.
