A Newer Approach to Aerodynamic Design of Wings for Wide Range of Mach number Application

A flat surface wing is optimized for minimum induced drag for a high subsonic Mach number. Wing for transport airplane role is considered.Optimal warp is separated into twist and camber. Angle-of-attack is alleviated by the value of twist at root, and the optimal warp is reduced by this value. Now aerofoil thickness is superimposed and the 3-D aerofoils so generated are analysed for transonic flow through finite difference methodology.
