Other design variables such as , , etc., may also be considered, although for brevity these will not be shown in the argument lists below. The following dependent auxilliary functions and constraint functions are assumed to be known from suitable analyses: c ( AR, S ) = S/AR (1) b ( AR, S ) = S AR (2) W wing ( AR, S ) = . 6 c 2 b foam g (3) W ( AR, S ) = W wing + W fuse (4) 2 4 4 I ( AR, S ) = . 04 3 c (5) W 1+ fuse b 2 1+2...
