Lift-induced drag, induced drag, vortex drag, or sometimes drag due to lift, in aerodynamics, is an aerodynamic drag force that occurs whenever a moving object redirects the airflow coming at it. This drag force occurs in airplanes due to wings or a lifting body redirecting air to cause lift and also in cars with airfoil wings that redirect air ...
Parasitic drag is defined as the combination of form drag and skin friction drag. [3] [1]: 641–642 [4]: 19 It is named as such because it is not useful, in contrast with lift-induced drag which is created when an airfoil generates lift. All objects experience parasitic drag, regardless of whether they generate lift.
Lift-induced drag (also called induced drag) is drag which occurs as the result of the creation of lift on a three-dimensional lifting body, such as the wing or propeller of an airplane. Induced drag consists primarily of two components: drag due to the creation of trailing vortices ( vortex drag ); and the presence of additional viscous drag ...
Approximate theories for the lift distribution and lift-induced drag of three-dimensional wings are based on such analysis applied to the wing's horseshoe vortex system. [123] [124] In these theories, the bound vorticity is usually idealized and assumed to reside at the camber surface inside the wing.
Back in 1961, José Sarria, a part-time drag queen, became the first out gay candidate to run for office in the United States — 15 years before Harvey Milk, the first out gay man to be elected ...
In the early '90s, McCarthy performed as a drag queen named Miss Y around various venues and events in New York. McCarthy confirms she also channeled Divine for her new in-the-flesh iteration of ...
Couture and Bob the Drag Queen (Caldwell Tidicue) have known each other since to Season 8 of “RuPaul’s Drag Race.” But Couture says Bob has dreamed of pulling off this reveal for over ten years.
William Dorsey Swann (March 1860 – c. December 23, 1925) [2] was an American activist. An African-American born into slavery, Swann was the first person in the United States to lead a gay resistance group and the first known person to self-identify as a "queen of drag".
