The Gnome-Rhône 14N was a 14-cylinder, twin-row air-cooled radial engine created by Gnome-Rhône in 1937 as an advancement of the previous Gnome-Rhône 14K. This powerplant was utilized in several French aircraft and one German type during the period leading up to and including the early stages of World War II.

Design and development

Following concerns over the reliability issues of the 14K, Gnome-Rhône undertook a redesign focusing on enhanced piston and valve components alongside larger cooling fins, which increased the cooling surface area by 39%. Launched in 1937, the 14N rapidly became standard power for numerous aircraft. By 1939, improvements elevated the compression ratio from 6.1:1 to 6.8:1, resulting in greater engine output.

The evolution of the 14N gave rise to the Gnome-Rhône 14R, distinguished by its two-stage supercharger. Nevertheless, production of such advanced engines was constrained by the German occupation of France, postponing their extensive deployment until after World War II concluded.
