LARZAC: A Small Turbofan Engine for Military and General Aviation Aircraft

The Larzac turbofan engine, rated at 1318 deca Newtons (2965 pounds) thrust at sea level static, is now in final qualification as a powerplant for a new generation of military trainers, light strike fighters, and small business jets. The Larzac engine is being developed by two French companies through a joint controlling group known as Groupement TURBOMECA/SNECMA(GRTS). Teledyne CAE has an exclusive agreement with GRTS to market, sell and service the Larzac in the United States and Canada, and also has an option to manufacture the engine. This paper discusses the Larzac engine design, development, flight test, preliminary qualification test and manufacture.
