Turbomeca Marboré Explained

The Turbomeca Marboré is a small turbojet engine that was produced by Turbomeca from the 1950s into the 1970s. The most popular uses of this engine were in the Fouga CM.170 Magister and the Morane-Saulnier MS.760 Paris. It was also licensed for production in the United States as the Teledyne CAE J69.[1] In Spain the Turbomeca model Marboré II was manufactured by ENMASA under license with the name Marboré M21.

The original Marboré, as well as Marboré III, IV, and V were not produced in significant numbers. A typical weight for this series of engines is 140kg (310lb). Fuel consumption is 720L/h on the Marboré VI at 4500m (14,800feet), as compared to 520L/h on Marboré II engines (same altitude), as well as an increase of fuel consumption of 27% and a decrease in cruise range capabilities.[2]

Variants

Marboré I:Prototypes and test examples
  • Marboré II:The first major production version was the Marboré II, which had a maximum thrust of 3.9kN at 22,500 rpm. In its most basic form, it is a single-spool, centrifugal compressor turbojet. Fuel consumption was rated at 410L/h. Variations include military or civilian aircraft, oil tank design, auxiliary equipment, and exhaust pipe configuration. Some variants also included one axial stage compressor for additional performance. The engine dimensions differ depending on the variant, auxiliary components and mounting configurations.

  • Marboré IIG:[3]
  • Marboré III:
  • Marboré IV:
  • Marboré V:
  • Marboré VI:The Marboré VI series were slightly more powerful at 4.8kN instead of 3.9kN. Fuel consumption was only slightly higher at 450L/h. This was a 23% increase in thrust with slightly more than a 9% increase in fuel consumption. As a result, the VI series were used to re-engine many II-series powered aircraft, and Marboré II engines became available at discount prices.
