hi everyone

1-i have to compute polar [cl(cd)] for canard configuration (only half wing + horizontal tail) what is my reference area and reference lenght which chord and which area (main wing, tail or main wing + tail?)

2-i think there is need to put ref area and ref length for both (wing and horizontal tail) but there i can put only one ref area and ref length.

3- are we able to compute both of them (cl and cd) using only one ref area? i have some objections because cl depends from chord*span area (wing area), and cd depends from frontal area...
