Gnome 50 HP 7 Cylinder Rotary aero engine
Gnome 50 HP 7 Cylinder Rotary aero engine, with metal engine to fuselage gasket, engine starting handle and gear wheel, designed by Louis Seguin and Laurent Seguin, and made by Societe des Moteurs Gnome, France, 1908-1914. The engine has seven cylinders, machined out of solid nickel-chrome-steel ingots. The cylinders and crank-chamber revolve around the stationary crankshaft. The carburettor, which is stationary, is of the single-jet type and feeds the engine through the hollow crank shaft. The connecting rods all operate on a single crank pin. Henri Farman used this type of engine to win a prize for the greatest distance flown (180 km), setting a World record.
