The Turbomeca Turmo is a French turboshaft engine developed for helicopter use. A descendant of Turbomeca's pioneering Artouste design, later versions delivered around 1,200 kW (1,610 shp). A turboprop version was developed for use with the Breguet 941 transport aircraft.
Current versions are built in partnership with Rolls-Royce, and the engine is produced under license by the Chinese Changzhou Lan Xiang Machinery Works as the WZ-6 and Romanian Turbomecanica Bucharest as the Turmo IV-CA.
