Rolls-Royce has successfully completed altitude and operability testing of its F130 engine, a crucial step in the program to re-engine the U.S. Air Force’s B-52J Stratofortress bomber fleet. The testing took place at the U.S. Air Force’s Arnold Engineering Development Complex in Tennessee, where engineers from Rolls-Royce collaborated with Air Force personnel to validate the engine’s performance under various mission conditions.
The testing campaign included altitude assessments to demonstrate the engine’s capabilities during sustained high-altitude operations. Additionally, operability tests utilized distortion screens to replicate turbulent airflow, alongside Integrated Drive Generator testing conducted with Boeing to ensure stable electrical power generation during missions.
“Completing this phase of the F130 engine testing program on-time and on-budget showcases our commitment to the U.S. Air Force,” stated Jennifer Schwerin, Director of Early Life Cycle and Naval Programs at Rolls-Royce Defence. She emphasized the collaborative efforts with Boeing and the Air Force, noting the confidence built in the F130’s ability to meet mission requirements.
The tests yielded significant data across the engine’s operating envelope, according to Lt. Col. Timothy Cleaver, U.S. Air Force program manager for the B-52 Commercial Engine Replacement Program. “Throughout this F130 engine test campaign, we gathered essential data about how this engine operates across the full spectrum of flight conditions,” he remarked. The completion of tests at the Arnold facility reinforces confidence in the engine and its associated systems as the program progresses toward aircraft modifications and flight testing.
Path Forward for the F130 Engine Program
This milestone follows the Critical Design Review completed in late 2024, which cleared the way for the construction of the first flight-test engines. Previous testing included sea-level trials in Indianapolis and “rapid twin-pod” tests at NASA’s Stennis Space Center to validate the engine’s configuration for the B-52’s twin-engine pod arrangement.
Looking ahead, the program will advance into further system integration and additional dual-pod testing before commencing flight trials. The F130, derived from the BR725 commercial engine family, is designed to enhance reliability, simplify logistics, and reduce maintenance needs for the long-serving B-52 fleet.
Once production begins, Rolls-Royce plans to manufacture, assemble, and test the engines at its Indianapolis facility, ensuring that the B-52J fleet is equipped with state-of-the-art technology to support its operational effectiveness for years to come.
