Made by Laurent Seguin | Science Museum Group Collection

Gnome 50 HP 7 Cylinder Rotary aero engine, with metal engine to fuselage gasket, 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.
