Whats the original engine? JT9Ds? If so, why are they re-engined? Wasn't the C-5 the first airplane ever to use high-bypass Turbofans?
|Quoting SATL382G (Reply 5):|
They are being reengined because the TF-39, being on one airframe only, was never seriously developed. The CF6, which sprang out of the TF-39 program, was and is in service on a number of commercial airframes. The benefit of the reengining to the C-5 is more power, better fuel economy, and ease of maintenance.
|Quoting RayChuang (Reply 11):|
If I remember correctly, the engines the C-5's will get are the same engines used on the E-4B and VC-25A: the GE F103 turbofan, essentially a military version of the CF6-80 turbofan used on 767's, 747's and A330's.
|Quoting TheSonntag (Reply 14):|
Are there really differences between military and civilian engines? Obviously there are, but why? To make C-5s more FOD resistant, or are there other reasons?
