i seem to remember that one pound of thrust was equal to one horse power at
240
mph or maybe it was 240 kts? is that not correct?  thanks tom Kimsey

One HP = 550 pounds moving at one FPS or 1 pound moving at 550 FPS.
So 240 MPH is only 352 feet per second.
One Kt is equal to 1.688 FPS so 240 kts would be 405 FPS.
Neither one of those work.

Lets go the other way 550 FPS is 375 MPH. So one pound of
thrust at 375 MPH is on HP.
