The wing given by Problem 5.25 oscillates with the reduced frequency of (k=0.2). Obtain the lifting pressure
Question:
The wing given by Problem 5.25 oscillates with the reduced frequency of \(k=0.2\). Obtain the lifting pressure curve for the spanwise change. Find the total lift coefficient.
Problem 5.25
A delta wing with sweep angle of \(45^{\circ}\) undergoes a simple harmonic plunge oscillations at \(\mathrm{M}=1.054\) at \(\mathrm{k}=0.525\). Find and plot the real part of the velocity potential
(i) at the root,
(ii) at \(\mathrm{y} / \mathrm{l}=0.6\),
(iii) \(\mathrm{y} / \mathrm{l}=0.9\).
(use 25 Mach box for half of the wing).
