The Turbomeca Marboré is a compact turbojet engine developed and manufactured by Turbomeca during the period spanning the 1950s through the 1970s. Its main installations were on aircraft such as the Fouga CM.170 Magister and the Morane-Saulnier MS.760 Paris. In the United States, production was licensed under the designation Teledyne CAE J69. Additionally, in Spain, ENMASA built the Marboré II variant under license, naming it the Marboré M21.
Limited production characterized early models including Marboré I, III, IV, and V. The engine typically weighs approximately . When comparing fuel consumption at , the Marboré VI uses , whereas the Marboré II consumes , representing a 27% increase in fuel usage but offering enhanced thrust and operational efficiency.
Variants
- Marboré I
- Initial prototype and experimental units.
- Marboré II
- The first extensively produced model delivering maximum thrust of at 22,500 rpm. It employs a single-spool configuration with a centrifugal compressor and has a fuel consumption rate of . Differences among variants include military versus civilian adaptations, oil reservoir designs, auxiliary systems, and exhaust configurations. Some versions incorporate an axial compressor stage to boost performance.
- Marboré IIA
- Marboré IIB
- Marboré IIC
- Marboré IIF
- Marboré IIG
- Marboré III
- Marboré IV
- Marboré V
- Marboré VI
- Provides an increased thrust output of , approximately 23% higher than the Marboré II, with fuel consumption rising modestly by 9% to . This combination made it suitable for upgrading aircraft originally equipped with Marboré II engines, especially as surplus Marboré II units became available at lower costs.
