Temperatures could sweepback up into the 20swith dry, sunny spells in some parts of the country, the Met Office forecast.
The ground effects of wings with low- and medium-aspect-ratios and a small sweepback angle were investigated [7-11].
The cell ratio is decreased, and the shrinkage ratio is increased from the peak to the trailing edge, so the angle of sweepback shows up.
Variable 58 (Figure 13(g)) represents [[theta].sub.full,tip,8] which governs the back sweep of full blade at tip section (large value of variable 58 represents large sweepback).

In those early days of high performance jets, with an industry having only rudimentary knowledge of supersonic aerodynamics, no computers to help design either airframes or engines, and a wing sweepback design copied from a German jet, it was no surprise that the airframe had very troubling flight characteristics (highlighted when NA's chief test pilot George Welch was killed during a high-speed dive, the first of several crashes), and the engine encountered severe compressor stalls caused by inlet duct curvature.
Finally, the wings sweepback at 32.2 degrees to reduce drag, while raked tips further enhance their efficiency.
