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 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 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 4.8 kN (1,100 lbf) instead of3.9 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 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 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). An increase of 27% fuel consumption and a decrease in cruise range capabilities.[2]
