The Viale 35 hp was a five-cylinder, air-cooled, radial engine for aircraft use designed and built in France by the Italian engine designer Spirito Mario Viale, that was first run around 1910. It developed 35 horsepower (26 kW). Three- and seven-cylinder variants of the same engine were built, although little is known about them.[1]
