Settle the Bet

[FlyFlyFly]

Anyone know of a turbofan engine other than the GE CF700 where the priumary measure of power is EPR?

 

[Gulfstream 200]

How about the BMW-Rolls Royce BR700?

most any pratt&whitney uses EPR jt8, jt9, 2037, 2040, etc

Do you remember the Air Florida 737-200 crash?

They set takeoff EPR, that is the primary power setting in the 737-200 Pratt JT8D, if they would have crosschecked the N1 and seen they were only at around 60 percent they would have added power and said the heck with the EPR setting, and they wouldn't have crashed and went into river.

Here are the Air Florida NTSB reports

I was wrong, they did note an engine instrument reading anomaly, so they new something wasn't right but they continued the takeoff instead of aborting. The new 737 primary power setting is N1, no more EPR gage.

Here is the Synopsis

I think he said turbo fan.

I think he said turbo fan.

I didn't catch that part.

Now I have a question, is the CF700 the only turbofan with the fan in the back?

i'm a fan of any angine that has a turbine

Hopefully a Tri-Star driver will confirm this, but I think the RB-211 is another one.

And the GE CJ805 on Convair 990's is another aft-fan engine.
