Gnome Omega No. 1 Rotary Engine

This rotary engine was designed and built by the brothers Laurent and Louis Seguin. It first ran in 1908, and first flew when "Henry Farman installed the first Gnome in his plane in April 1909 and from the outset made the most beautiful flights of the time." The initial series of Gnome engines, known as Model "Omega," featured cylinders having thin cooling fins machined from one heavy solid nickel steel billet, a two-piece crankshaft, and ball bearings for the master rod, all done to the highest standards of quality. More than 3000 sold by 1913. It was the most popular rotary engine.
