TFE731 Turbofan Engine
TFE731 Turbofan Engine
Multiple TFE731 models offer 3,500 to 5,000 pounds of thrust, backed by more than 100 million flight hours of proven experience, performance, and reliability.
Our TFE731 family of engines has a legacy of proven reliability.
The first TFE731 was certified in 1972. Since that time, 20 different models with more than 13,000 units have been produced, logging an astounding 100 million plus hours of service on more than 30 different aircraft applications. The TFE731 gives you everything you want in an engine with proven experience, performance, and reliability.
Though most people would be satisfied with the performance of the legendary TFE731 turbofan engine, our engineers have continued to make engine improvements. In fact, for the TFE731-50R engine, they made 70 improvements to the already robust engine, including improved core and low-pressure spool technologies, new digital electronic engine control (DEEC) and a complete nacelle and thrust reverser system.
These changes resulted in greater versatility, dramatically improved temperature margins, a better lapse rate than the TFE731-5BR and, depending on altitude condition, up to eight percent better specific fuel consumption (SFC).
