For the wing given in Example 8.3, evaluate 

(i) the maximum normal force Coefficient, 

(ii) minimum side force coefficient.

Example 8.3

At \(25^{\circ}\) angle of attack, a wing with \(80^{\circ}\) angle of sweep rocks with period of \(0.39 \mathrm{~s}\). and amplitude of \(32^{\circ}\). Obtain the graph of \(C_{R}\) versus \(\phi\) and \(C_{D}\) versus \(\dot{\phi}\), and comment on them. Data: \(a_{1}=-0.0572, a_{2}=0.1362, a_{3}=0.0514\), \(a_{4}=-1.403, a_{5}=-1.943, a_{6}=0.075\).
