First, thrust during takeoff is relatively constant, from the beginning of
the takeoff roll, to actually leaving the runway. This is more true for
jets, but is reasonably close to the truth even for propeller-driven

At least ones with constant-speed props. It seems to me that you get
much better thrust at low speed with a CS prop. My understanding,
which may be defective, is that at low speed much of the fixed-pitch
prop is stalled. I'd like to see a plot of airspeed vs. thrust for this, but
don't have any idea where to look for one. Any suggestions?
