Manufacturing and maintaining different aircraft fleet leads to various purposes, which consumes
more money as well as man power. Solution to this, nations that are leading in the field of aeronautics
are performing much research and development works on new aircraft designs that could
do the operations those were done by varied aircrafts. The foremost benefit of this delta wing is,
along the huge rearward sweep angle, the wing’s leading edge would not contact the boundary of
shock wave. Further, the boundary is produced at the fuselage nose due to the speed of aircraft
approaches and also goes beyond the transonic to supersonic speed. Further, rearward sweep
angle greatly worse the airspeed: wings under normal condition to leading edge, so permits the
aircraft to fly at great transonic, subsonic, or supersonic speed, whereas the over wing speed is kept
to minimal range than that of the sound speed. The cropped delta wing with fence has analysed in
three cases: Fences at 3/4th distance from the centre, with fences at half distance from the centre
and with fences at the centre. Further, the delta wing that cropped is exported to ANSYS FLUENT
V14.0 software and analysed by making the boundary condition settings like sonic Mach number
of flow over wing along with the angle of attack.
