the TF39 has a sound that NO other engine can match! that Growl, that scream, that power! Flew on 3 different C-5's in my army days in 1987-1991! Until you sit on top of a C5 in the passenger area, and you hear and feel the power of those TF39's, you haven't lived!

I used to live right in the approach path of Lackland AFB. I still remember the scream of the TF39s anytime a C5 would fly over the house. It was always music to my ears

The explanation of this technology was spot on, as someone still learning about turbofans and turboprops and jet engines in general I appreciate the details about how this TF39 came to be. The sound of this engine is simply ethereal. Thanks again for this video.

And the TF39 was the strangest but coolest sounding jet engine in the world, what made it sound so different?

1.5 Staged T-Fan and N1 Fan. The JT9D also has the similar version, but produced slightly more amount of thrust, but doesn't have an N1 Fan, due 2 which it sounds slightly less louder. The commercial CF6's earlier variants, the CF6-6 and CF6-50, whose USAF Designation is GE F103 variant that doesn't have a 1.5 T staged Fan, also sounds as loud as TF39

The TF39’s, the CF6-6, and the LM2500 share a large number of parts. For instance the 14 stage HPC is the same for all 3 engines. The LM2500 is still in production; thus GE is still making all the common parts. You are right in saying the TF39’s are not in service. The last C-5 Galaxy was upgraded to CF6-80C2 (F138’s) in 2017.

The CF6 is a descendent & development of the TF-39, but I do have a question. In the TF-39 the booster stage is in front of the big fan, while in the CF6 and every engine afterwards the booster stage in behind the main fan. Why the change in philosophy?

J85-21, piece of junk. #2 bearing needed to be replaced due to a bad batch, every engine that came into the shop for any reason had to have it changed, complete engine tear down, 12 hr shifts 6 days a week working on them at RAF Alconbury back in the 70's and 80'scouldn't keep them in the F5 Tiger II's, constant engine changes due to combustion baskets burning up.

The J85's that went into our Tutor jets were the most reliable engine I've worked on. I guess they mucked it up by putting that extra stage in.
