Question 6 (25 marks) a) A conventional aircraft is in trimmed, level, unaccelerated flight. The wing is generating 178 KN of lift and has a pitching moment about the aerodynamic centre of -27116 Nm. The aerodynamic center of the wing is located at 0.25c, the center of gravity is located at 0.45c, the aircraft has a chord of 1.5 m and the symmetric tail aerodynamic center is located 3 m behind the center of gravity. What is the lift generated by the tail and what is the weight of the aircraft? (Assume thrust and all drag forces act through the center of gravity) (20 marks) b) When an aircraft goes supersonic, its aerodynamic center shifts from 0.25c to 0.5c. How would this change the longitudinal static stability of a conventional aircraft? (5 marks)
