Title: Saw Toothed Leading Edge Delta Wings. The present invention comprises of a sharp saw tooths at leading edge of delta wing can act like a protuberance and encourages a vortex flow on the surface of the delta wing, delaying stall towards higher angles of attack. These saw tooth are placed on the leading edge of the delta wing up to some portion of the length, where the flow physics is to be altered to encourage stable pair of vortices. The saw tooths are designed such that they look like alphabet Z facing the sharp corner directly to the oncoming flow field. The design of tooths is chosen in a way that they stabilize the existing vortices and adds small vortices to the primary vortex. These stabilized vortices creates low pressure zone by which the lift increases and the flow is attached to a longer extent in the flow direction, whereby the drag is also expected to increase. The present invention further provides maneuverable wings even at higher angles of attack.
