Consider a torsionally elastic (GJ = 8000 lb-in2) wind tunnel model of a uniform wing, the ends of which are rigidly fastened (fixed) to the wind tunnel walls. The model is a symmetric airfoil with a span of 3 ft and a chord length of 6 in. The total lift-curve slope is 6 per rad. The aerodynamic center is located at the quarter-chord, and both the mass centroid and the elastic axis are at the mid-chord. (a) Calculate the divergence dynamic pressure at sea level. (b) Calculate the divergence airspeed at sea level.
