Calculate the value of the moment coefficient about the aerodynamic center and the location of the aerodynamic center.
Consider the model in Prob. 7.2. If a mass of lead is added to the rear of the model so that the center of gravity is shifted rearward by a length equal to 20 percent of the chord, calculate the moment about the center of gravity when the lift is 4000 N. Prob. 7.2. Consider a model of a wing-body shape mounted in a wind tunnel. The flow conditions in the test section are standard sea-level properties with a velocity of 100 . The wing area and chord are 1.5 m2 and 0.45 m, respectively. Using the wind tunnel force and moment-measuring balance, the moment about the center of gravity when the lift is zero is found to be -12.4 N · m. When the model is pitched to another angle of attack, the lift and moment about the center of gravity are measured to be 3675 20.67 N · m, respectively. Calculate the value of the moment coefficient about the aerodynamic center and the location of the aerodynamic center.
