Aerodynamics of Reverse Delta Wing

Delta wings are mostly used in supersonic jets and fighter aircrafts. A delta wing is naturally stable and produces vortex lift, so the flow separation can be made into increasing lift. This augmented lift comes at an expense of high drag. A reverse delta wing is nothing but an inverted delta wing, the forward swept wings were inspired from this design. It has low drag coefficient and was used in ground effect vehicle. This paper aims to bring out all the possible studies and research work done on a reverse delta wing. The study was mainly inspired by the works of Alexander Lippisch and his design for the X-112 WIG (wing-in-ground effect).This paper will provide comparative flow patterns around a reverse delta wing and a normal wing with simulations and ways to optimize it to get a better efficiency.
