NASA seeks replacement engines for aging WB-57 aircraft

NASA’s Ames Research Center (ARC) in California is soliciting information from potential sources for a feasibility study concerning the replacement of the existing Pratt & Whitney TF33 engines on their WB-57 aircraft.

Planning Purposes Only

No contract solicitation exists at this time, NASA said in a Request for Information (RFI) document released on Tuesday. The RFI is for informational and planning purposes only and is not a request for proposal, nor does it constitute a commitment to procure any goods or services.

“Vendors having the capabilities necessary to meet or exceed the stated requirements are invited to submit appropriate documentation, literature, brochures, and references,” the agency said in the RFI.

NASA is seeking information from industry regarding potential replacement engine options for the WB-57 aircraft, which currently operates with Pratt & Whitney TF33 engines.

WB-57 Mission

The WB-57 aircraft is a high-altitude, long-endurance platform used for atmospheric research, sensor testing, and communication relay. NASA aims to modernize the fleet and ensure long-term sustainability by exploring potential engine upgrades.

Performance Improvements

NASA seeks quantifiable performance improvements, including but not limited to:

                 o Increased thrust

                 o Improved fuel efficiency

                 o Reduced maintenance costs

                 o Extended operational range

                 o Enhanced operational ceiling

                 o Other relevant performance metrics

Interested firms having the required capabilities necessary to meet the above requirements should submit a capability statement to NASA ARC no later than May 22.

Can any of the data and testing from the B-52 re-engining effort, also with Pratt & Whitney TF33 engines.

WB-57s are amazing aircraft, used to do testing of the Battlefield Airborne Communication Node (BACN) / Objective Gateway that now flies on the USAF E-11 aircraft.

Can not believe B-57's are still flying. I saw them in early '60's while in Air force. I think they had shot gun start engines at that time.

I hope the new engines have that same sound! I always love when the WB-57s fly over from Ellington Field here at the Johnson Space Center. We call them Batplanes
