Hi
I need a perspective so this is a general question . If a 6 foot dia.
tail rotor is turning 2500 rpm how many pounds of static thrust at a
particular pitch angle would be produced????

That would depend on the chord and aerofoil section of said rototr blade.
Given all those values, it wouldn't be difficult to do the sums.

And is that for a flat
rotor blade meaning no helical twist. Any senario close to the above
would be a big help. I want to build a variable pitch rotor and need to
get an idea on the thrust output .

May I suggest a book on aerodynamic principles and mathematics? And no, I'm
not being funny, I'm being serious because without some grounding in the
basics, you're going to struggle finding answers that are simple to find
inside a calculator.
