Unformatted text preview: moment about the center of gravity when the lift is 4000 N. Problem 3: (if ‘tail’ is not covered by 11/01/11, you may ignore this problem) Consider the model in Problem 1. Assume that a horizontal tail with no elevator is added to this model with the incidence angle i t = 0). The distance from the model’s center of gravity to the tail’s aerodynamic center is 1.0m. The tail area is 0.4 m 2 . The lift-curve slope of the tail is 0.12 per degree. From experimental measurements ε = 0 , and . If the absolute angle of attack of the model is 5 o , and the lift is 4134 N, calculate the moment about the center of gravity. Does this model have longitudinal static stability and balance?...
