Skin discoloration can be due to changes in melanin. Melanin is a skin pigment that gives color to the skin. Changes in melanin can also cause skin to be patchy. Treatment for skin discoloration includes using topical treatments.
Winglets increase an aircraft's operating efficiency by reducing what is called induced drag at the tips of the wings. An aircraft's wing is shaped to generate negative pressure on the upper surface and positive pressure on the lower surface as the aircraft moves forward.
how the wing behaves in flight. The vortex lattice method is applied across the wing to help compute lift and induced drag at different parts of the wing. These results are used as a reference to compare the effects of adding wingtips to the original wing. To understand the properties of winglets on a wing, one form of winglet is chosen. There are
