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).
Swing trading is a speculative trading strategy in financial markets where a tradable asset is held for one or more days in an effort to profit from price changes or 'swings'. [1] A swing trading position is typically held longer than a day trading position, but shorter than buy and hold investment strategies that can be held for months or years.
Payoff chart from buying a butterfly spread. Profit from a long butterfly spread position. The spread is created by buying a call with a relatively low strike (x 1), buying a call with a relatively high strike (x 3), and shorting two calls with a strike in between (x 2).
The first and most significant level of support (S 1) and resistance (R 1) is obtained by recognition of the upper and the lower halves of the prior trading range, defined by the trading above the pivot point (H − P), and below it (P − L). The first resistance on the up-side of the market is given by the lower width of prior trading added ...

Thin supercritical wing section and swept-back wing can postpone shock stall to higher speed. [1] A stall is the decrease in lift to a value below the weight, and the associated increase in drag upon the separation of the boundary layer (in this case behind the shock wave).
Simmer eggs in a rich tomatoey cream sauce studded with chickpeas and silky spinach for a super-fast vegetarian dinner. Serve with a piece of crusty bread to soak up the sauce.
An example of a wing without protuberances compared to a wing with protuberances is shown. The geometry of tubercles must also be considered, as the amplitude and wavelength of tubercles have an effect on flow control. Tubercles can be thought of as small delta wings with a curved apex, since they create a vortex on the upper edge of the tubercle.
