Unformatted text preview: : 0.25 Coefficient of moment about the aero-center :-0.03 Zero-lift downwash angle, : 0 deg Downwash angle slope, : 0.25 deg-1 A horizontal stabilizer/tail (with no elevator) with a plan area S t of 2.5 m 2 and a lift curve slope a t of 0.1 /deg , is given to you. For a c.g. location, h = 0.2 determine the horizontal location of the tail and the tail setting angle , to ensure a static margin SM of 0.15 , and that the a/c can be trimmed at an angle of attack of 5 deg . (assume that the tail is relatively of negligible mass) Problem 3 : Assume that the aircraft in Problem 2 weighs 10,000N (with h = 0.2; SM = 0.15 ). How far behind the cg can a passenger of mass 60kg ( 588.4 N ) be seated to ensure a statically stable airplane?...
