The short version is that propeller thrust = horsepower @ 375 mph. HP is
greater than thrust below that speed, less above.

Guy, is this the same as saying that a turbojet's thrust in pounds at
375mph is the same as a horsepower rating for that engine?

Put another way: is a 3,000-lb thrust turbojet equivalent to a 3,000hp
recip at 375mph?

(I haven't been reading this thread either. Yesterday I discovered
that if I posted first, my newsreader downloaded all the new posts,
and if I then downloaded all the new posts (as I did) I wiped out the
day's work of all these brilliant people.)
