How Much Thrust Could A Low By-pass Tf-39 Make?

Wed Jul 26, 2006 1:24 am

I was thinking about how GE was able use the loud low by-pass F-101 design, and make a quiet High by-pass engine like the CFM-56. It got me to thinking, what if they took the loud high by-pass TF-39 and reduce it fan size and it's BPR to 2:0 and make a low by-pass version of it. So if GE was to make a low by-pass version of the TF-39 with afterburners, how much power do you think they could get out of it?

There's no reason to use the TF39 core for anything. It's ancient.

The F101 is ca. 31,000 pounds thrust (at sea level/static conditions).
Its derivative, the F110, is 29,000+. The next step up in thrust, the F136, already exists, with decades-newer technology in every component.

If in some alternate universe the TF39 core were used for a low bypass turbofan, I'd guess it would be in the 34-38,000 pound thrust class in afterburner.

Finally, please use the correct designations for these engines: F101, CFM56, TF39; no hyphen. A hyphen is used after the digits to designate subtype, such as CFM56-7, TF39-1C, or F110-129.
