Propeller Design
Propeller Design
(OP)
Hi, I’ve been trying to design a propeller from cero, I’ve studied Theodorsen´s paper and I do understand the procedure for obtaining the optimum distributions for an specific flying condition (speed, HP, rpm), but how to design the propeller for the whole aircraft operation , because the paper gives guidance to design for an specific flying situation.
I´ve tried doing an average of the optimum chords for every flying condition, but at low speeds the chords tend to be very wide, so the resulting prop seems different in shape whit the commons props.
Perhaps Theodorsen´s method is too old, is there any other methods for prop design?
Thanks.

RE: Propeller Design
not much practical help ! then in the real world you've also got the cost considerations, how expensive is something to make ? is the performance gained worth it ?
good luck
