The French Gnome engine company was the first to produce successful and widely produced rotary engines for aviation beginning in 1908. In 1913, previous two-value cylinders were redesigned to have only one-value (monosoupape) to simply the design and improve durability. A British aircraft designer declared it “one of the greatest single advances in aviation.”

The Omage powered a large range of early aircraft manuafacturers including: Avro, Blackburn, Bleriot, Bristol, Farman, Royal Aircraft Factory, Short, Sopwith, Vickers and Voisin among others.
