F110-GE-132: Enhanced Power Through Low-Risk Derivative Technology

Abstract

The F110-GE-132, originally referred to as the F110-GE-129 EFE (Enhanced Fighter Engine), presently undergoing qualification testing, is being offered at two different thrust/inspection levels with a maximum augmented thrust of 34,000 pounds. The EFE has been developed using low-risk derivative engine technology. It features a new increased airflow, high efficiency, three-stage long chord blisk fan, and an advanced radial augmentor that reduces complexity, improves maintainability, and provides increased parts life. The paper first provides a historical background of the F110 engines to relate the heritage of the F110-GE-132. The F110 engine model development roadmap is shown to illustrate the incremental low-risk approach used to provide thrust growth with improved product reliability. A detailed description of the unique power management features of the EFE engine to meet individual customer thrust and life requirements is outlined. The long chord blisk fan design, development, and test results are presented, followed by a description of the radial augmentor and the exhaust nozzle. The EFE engine has successfully completed sea level static and altitude development testing and fan aero mechanical qualification at the AEDC in Tullahoma, Tennessee.
