    Abstract

    This paper deals with the use of lifting symmetric super-13; critical airfoils in the wing design of a combat aircraft.13; For transonic combat aircraft requiring supersonic accele-13; ration, the usual supercritical airfoil which invariably has : camber is not suitable because of the supersonic wave drag penalty arising from the camber. TherexA3;ore, lifting symmetric supercritical airfoils which overcome this disadvantage were developed by the authors, and their beneficial effects in the two-dimensional case were demonstrated earlier. The objective of this paper is to demonstrate that the benefits obtained in the two dimensional performance extends to some extent even for the three-dimensional performance when such symmetric supercritical airfoils are used in finite wings of the combat type aircrafts.
