Dear fellow designers, I would very much appreciate your input on the use of a flap to be mounted on a canard currently taking shape on my drawing board. The idea is to mount the flapped surface in such a way that its deployment will have minimal effect on airplane pitch. My questions are as follows:
a)where should I place the flap relative to the c.g. (or to the n.p.) ?
b)do you think a combined flap/slat surface would be feasible and more effective ?

My spontaneous thought...... would be to have the 25% chord point of the flapped surface to coincide with the c.g. as depicted but before I proceed please feel free to have your viewpoints on this….Thank you….and…..Cheers/Harald

PS….yes indeed I could combine lowered flaps on the main wing and foreplane via a mixer to achieve this but for certain reasons I will not do that in this case….(please disregard my two empty uploads-dunno how to delete them).…DS
