The aerodynamic characteristics of a highagility aircraft of canard-delta wing type are analyzed in detail comparing the performance obtained by smooth, variable camber wing trailing- edge sections versus conventional trailingedge flaps. Wind tunnel tests are conducted on a detailed model fitted with discrete elements representing the adaptive wing trailing-edge sections.
