General information
Free-turbine turboshaft engine with rear power output, designed and developed from 1959 for helicopter use by the technical office led by Joseph Szydlowski. The name Turmo means "Turbine Motrice" (driving turbine).
About 2,600 engines of the Turmo family were built up to 1995, not counting derivatives for land and naval use.
The Turmo II, IIIC, III C4 and IVC versions were built for the medium helicopters Sud-Aviation Frelon, SA321 Super Frelon and SA 330 Puma, with power outputs growing to 1,580 shaft hp. Installed in the Renault Étoile Filante, the Turmo I version set a world speed record for cars.
The 1,500 shaft hp III D version in the collection was developed for the Bréguet 941, a four-engine short-take-off transport with blown wing, of which only four were built. It is therefore the rarest member of a family built in large numbers.
History of this engine
The engine was built in France in June 1967. It was acquired some years ago, probably from a scrap dealer, and has not undergone any restoration.
It is fitted with a display stand.
