Fouga ZéphyrVariants Teledyne CAE J69 The Turbomeca Marboré was a small turbojet engine produced by Turbomeca from the 1950s into the 1970s. The most popular uses of this engine were in the Fouga Magister and the Morane-Saulnier MS-760. It was also licensed for production in the United States as the Teledyne CAE J69,[1].

Variants
The first major production version was the Marboré II, which had a maximum thrust of 880 lbf (3.9 kN) at 22,500 rpm. In its most basic form, it is a single-spool, centrifugal compressor turbojet. Fuel consumption was rated at 109 gal/h[vague]. 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 of different variants with different auxiliary components and mounting configurations.
These were eventually replaced by the Marboré VI series which were slightly more powerful at was 1080 lbf (4.8 kN) instead of 880 lbf. Fuel consumption was only slightly higher at 119 gal/h[vague]. This was a 23% increase in thrust with slightly more than a 9% increase in fuel consumption. As a result the IV series were used to re-engine many II-series aircraft, and Marboré II engines are still available cheaply as surplus for the experimenter.
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 kilograms or 310 pounds.
Fuel consumption is 190 gallons per hour on the Marbore VI at 15,000 feet, as compared to 138 gallons per hour on Marbore II engines (same altitude). An increase of 27% fuel comsumption and a decrease in cruise range capabilities.[2]
