Turbomeca Aubisque

The Turbomeca Aubisque was a small turbofan engine designed and produced by Turbomeca in the 1960s. Its only application was the Saab 105 military trainer aircraft as the RM9. The engine is named after the Col d'Aubisque in the Pyrenees mountains, in line with company tradition.

The earlier Turbomeca Marboré turbojet was originally intended for the Saab 105, but when Saab needed more thrust than the Marboré produced, Turbomeca offered the Aubisque turbofan. Basically a turbofan version of the Turbomeca Bastan turboprop, the Aubisque went into the production for the Saab 105. About 300 were produced. They were in service for 30 years until replaced in the mid-90's, by the Williams FJ44 turbofan, for the remaining Swedish Air Force Saab 105s.
