Supercritical airfoils feature four main benefits: they have a higher drag-divergence Mach number, [21] they develop shock waves farther aft than traditional airfoils, [22] they greatly reduce shock-induced boundary layer separation, and their geometry allows more efficient wing design (e.g., a thicker wing and/or reduced wing sweep, each of which may allow a lighter wing).

An example of a readable book [b]. Each of the nine countries covered by the library, as well as Reporters without Borders, has an individual wing, containing a number of articles, [1] available in English and the original language the article was written in. [2] The texts within the library are contained in in-game book items, which can be opened and placed on stands to be read by multiple ...
The NACA four-digit wing sections define the profile by: [2] First digit describing maximum camber as percentage of the chord. Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. Last two digits describing maximum thickness of the airfoil as percent of the chord. [3]
The supercritical wing, hands-on-throttle-and-stick (HOTAS) control principle, and increased engineered lateral stability make the aircraft fundamentally easier to fly. [ 71 ] [ 72 ] Ed Harper, general manager for the McDonnell Douglas Harrier II development program, summarizes: "The AV-8B looks a lot like the original Harrier and it uses the ...
The judge "wrote an opinion that is knowingly unlawful, goes against our Constitution, and, if allowed to stand, would be the end of the Presidency as we know it," Trump wrote in his post.
A shock stall is a stall created when the airflow over an aircraft's wings is disturbed by shock waves formed when flying at or above the aircraft's drag divergence Mach number. Shock stall may cause control problem during speed transition (transonic to supersonic). Thin supercritical wing section and swept-back wing can postpone shock stall to ...
We’ll know just how real Kurtis Rourke’s chances of winning the Heisman are on Saturday. The Indiana QB is the co-No. 4 favorite for the award heading into the No. 5 Hoosiers’ gargantuan ...
