Unformatted text preview: a : 0.075 deg1 Aerodynamic center location, : 0.25 Coefficient of moment about the aerocenter :0.03 Zerolift downwash angle, ε : 0 deg Downwash angle slope, : 0.25 deg1 A horizontal stabilizer/tail (with no elevator) with a plan area S t of 0.025 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. solution: Problem 1: Use the subscripts “E” for endurance and “R” for range. Since it is given that , from above we get . So that Now, since , we have: for range and for endurance. From these, . This yields Problem 2: Now use to get To determine , use the trim condition :...
