Question

rplane for which the starboard half-wing has the geometry give in Figure 1. For this wing, the lift curve slope is CLaw 5.0 per radian and the aileron flap effectiveness parameter is 0.2 Estimate the aileron power Cl for the airplane. (This and the next problem refer back to the Topic 3 notes. You might also inthe supplemenial ro Aerodynamic Properties relevant.) 2.75 m I Cfc-0.25 1.34 m 3.4 m 4.8 m 5.2m Figure 1: Half-wing of an airplane for Problems 3 and 4 incorporated into a low-wing aircraft design Find the wing dihedral angle「required to produce a dihedral effect of Clg- per radian, neglecting wing/fuselage interference effects. For simplicity, assume that the increment (or decrement) in lift due to sideslip β acts at the mid-span of the right (or left) wing. Note that the change in lift coefficient is CLaw (rs), depending on the half-wing being considered. -0.1
