Delta wing is primarily in the form of a triangular shaped planform. The advantage of delta wing is that flow remains attached to the wing surface even at high angles of attack which result in the delay of the stall and hence enhances the lift coefficient and performance parameters [4], [5].The enhancement in lift is due to the …

Further ...
WebA rounded leading edge delta-wing exhibited a dual vortex primary structure and, for any given AoA, a stall delay. Extensive experimental investigations were performed by Breitsamer [22] to assess the unsteady effects of breakdown over the turbulent flow that develops over a DW in near- and post-stall incidence. A delta wing is a wing shaped in the form of a triangle. ... This also improves stall characteristics and can benefit supersonic cruise in other ways. Moving the centre of mass forwards and trimming the elevator to exert a balancing downforce. In the extreme, this reduces the craft's ability to pitch its nose up for … See more A delta wing is a wing shaped in the form of a triangle.
