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.
