Hello from NZ.
I am designing and building a 1917 Albatros DVa 3/4 scale replica and need to know how to find the centre of preasure of the wings. The top wing has 18ft 5'' lifting span and 42 inch cord. Bottom wing 20ft X 27inch cord,gap 48inches, stagger to be 30 degrees I am not formula literate so would appreciate simple terms
Thanking you in anticipation,
Alby

The centre of pressure changes with the angle of attacks. The book below has diagrams of many airfoils which show the cp, aoa, Cl, etc. It shows airfoils back to the Wright's and for WW1 a/c for US, English and European. If you can determine what airfoil was used in the a/c then you may be able to determine cp from graph. If you don’t have access to the book it is for sale on the internet.
