Al is correct about it taking HP to make static thrust
with a prop but the assumption about the relationship between HP and static
thrust is subject to a lot of variables. There is no fixed relationship
between static thrust and HP. If there were, you could not account
for the ability of most helicopters to hover.
You could easily increase static thrust by 1.18
by increasing the diameter of the prop and the reduction ratio of the
redrive with NO increase in HP.
But my real point was that static thrust is not a very
useful measurement to us.
You’re right; I agree with all of that.
