Curtiss JN4d Jenny - 1915
Curtiss JN-4 Jenny

The Curtiss JN-4 "Jenny" is a series of biplane aircraft built by the Curtiss Aeroplane Company of Hammondsport, New York, later the Curtiss Aeroplane and Motor Company. The Curtiss JN series (the common nickname was derived from "JN") was produced as a training aircraft for the U.S. Army although the "Jenny" became the "backbone of American post-war aviation."

Curtiss combined the best features of the model J and model N trainers, built for the Army and Navy, and began producing the JN or "Jenny" series of aircraft in 1915. Curtiss only built a limited number of the JN-1 and JN-2 biplanes. The design was commissioned by Glenn Curtiss from Englishman Benjamin D. Thomas, formerly of the Sopwith Aviation Company.

The JN-2, deficient in performance, particularly climbing, because of excessive weight, was an equal-span biplane with ailerons controlled by a shoulder yoke located in the aft cockpit. The improved JN-3 incorporated unequal spans with ailerons only on the upper wings, controlled by a wheel. In addition, a foot bar was added to control the rudder.
