After (J) is known, the coefficient of lift, Cl, can be obtained from 

 either A^ or 3j^, since 



I Fq^ (Gi) cos 26^ 



C, = 



i=l 



L 1/2 Flv cos 2(J) n 



1/2 F^^ cos 2(j) I cos^ 20^ 

 i = l

I Fov ^Qi) ^i" 20i 



i = l 



n 

 1/2 Flv sin 2(f) ^ sin^ 28^ 

 i = l

Alternatively, Cl could be obtained from A-^ and Bj^ directly without first 

 solving for (|), since 



^ A^^ + Bi^ = v/(l/2 Cl Flv cos 2(j))2 + (1/2 Cl Fl^ sin 2(\>)- 



= v^(l/2 Cl Flv)^ (cos^ 2cj) + sin^ 2(f)) 

 = 1/2 Cl Flv •
