B767 thrust

[Kevin]

According to the type certificate data sheet for the Pratt and Whitney
62,000 thrust engine, the max continuous thrust should be ~52,000 and
the 62,000 for 5 minutes max. The question is, does N1 @ 100% produce
52,000 lbs of thrust or does it produce 60,200 lbs of thurst? Any
airline pilots out there that can shed light on this?
Thanks, Kevin

Neither...N1 for a given thrust rating will vary with Temp/Pressure.
Airline engines are not "full throttle" engines while during my time,
military engines were. A military engine was set to produce 100% RPM
at full throttle, and they accepted either more or less thrust depending
on Temp/Pressure conditions. For commercial engines, an EPR/RPM is
computed for each takeoff and the thrust lever adjusted to obtain that
value.

Why do you ask Kevin? Are you putting a PW4000 on a homebuilt? <G>

I wish...But, no. I am asking b/c we're trying to configure an
aircraft in x-plane flight simulator and we'd like for everything to be
as realistic as possible. I disguised the question to ward off those
who are critical of others that post topics in groups that aren't
directly related to that specific group...
thanks, Kevin
