Correct.
I would agree, not only for this chart, but also for others in the Dash-1. The low-altitude lines all look like someone took a ruler and just drew a stright line through (0,0) - without any regard for what this physically means. That's the whole point I'm trying to make - to Yo-yo, to Rhen, to anyone who is interested. The Dash-1 contains some data that is too approximate for our use.
Back up a bit, I think you have misunderstood the order of cause and effect that I'm trying to present:
(1) By F=m*a, I have established, beyond any reasonable doubt, that the sea level thrust of the F-15C in Lock On does not exceed 34,000 lbf.
(2) Despite this, the sea level performance of the F-15C in Lock On matches the Dash-1.
(3) Therefore, the Dash-1 does not describe the sea level performance of the 47,000 lbf F-15C correctly.
(3) follows from (1) and (2), not the other way around.
Me?
Of course. I use the Streak Eagle data, which has so far given me no such ridiculous contradictions.
Does the Dash-1 have more useful charts?
No. They are all like that - straight lines that somebody drew with a ruler down from high altitude to the artifically fixed point of (0,0).
I have some more data, but it is MUCH more complicated to analyze. It's basically a graph of airspeed, altitue, Gs, turn rate, turn radius, etc. during a mock dogfight between an F-15 and an A-4. Beautiful stuff, but if we can't even agree on what thrust the F-15C should be producing at takeoff, and whether tLock On and/or the Dash-1 describe it correctly, then we have little hope of analyzing that.
Trouble is, do we know what the mil power thrust is supposed to be?
Much easier to analyze max power, I think. That thrust evel is published in many places, and is more easily verifiable.
Walk before we run.
