    CFD Analysis of Delta Wing Body Configurations at Lower Angle Of Attack
    Author(s): Satish Hiremath* and Anand M Raikar

    The delta wing is a wing plan form in the form of a triangle. It is named for its similarity in shape to the Greek letter delta (Δ). The first practical uses of delta wing came in the form of so-called "tailless delta", i.e. without the horizontal tail plane. As the angle of attack increases, the leading edge of the wing generates a vortex which energizes the flow, giving the delta a very high stall angle. Pure delta-wings fell out of favour somewhat due to their undesirable characteristics, notably flow separation at high angles of attack, high drag at low altitudes, low wing loading and poor maneuverability. The design of modern light weight fighter that can cruise supersonically, maneuver transonically and has a post stall capability requires additional highly swept area ahead of the main wing called strake or leading edge extension (LEX) which lead to some of the v..
