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]

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 140 kg (310 lb). Fuel consumption is 720 L/h (160 imp gal/h; 190 gal/h) on the Marboré VI at 4,500 m (14,800 ft), as compared to 520 L/h (110 imp gal/h; 140 gal/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 3.9 kN (880 lbf) at 22,500 rpm. In its most basic form, it is a single-spool, centrifugal compressor turbojet. Fuel consumption was rated at 410 L/h (90 imp gal/h; 110 gal/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 VI
- The Marboré VI series were slightly more powerful at 4.8 kN (1,100 lbf) instead of 3.9 kN (880 lbf). Fuel consumption was only slightly higher at 450 L/h (99 imp gal/h; 120 gal/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.

Das Turboméca Marboré war ein kleines Turbojettriebwerk der Firma Turboméca, das in den 1950er- bis 1970er-Jahren produziert wurde. Am häufigsten wurde es in der Fouga Magister und der Morane-Saulnier MS.760 „Paris“ verwendet. Auch in den Vereinigten Staaten wurde es in Lizenz als Continental-Teledyne J69 für die Cessna T-37 produziert. Eine spanische Lizenzproduktion wurde als M 21 bezeichnet.- [en] Turbomeca Marboré
