In straight delta wings the length “ У ” would be a natural dimension to define a length ratio. However, since the load distribution of slender delta wings is different from that in conventional planforms, there is no reason to use this type of mean chord. Shown for tapered wings in Chapter III, that chord measures c = (2/3)Я. Geometry of delta wings, illustrated by the example of an equilateral triangle. If defining a mean aerodynamic chord in the manner asįigure 1. As shown in figure 1, this type of wing is defined by the following parameters: Wings in the shape of a delta (with a straight trailing edge) are obtained by combination of sweep and taper. It is used in high speed aircraft, and there is analysis available explaining and predicting at least part of the lift. In the range of low aspect ratio wings the delta shape is of particular interest. Circulation around such Ages is obviously different from what was originally meant by that word in two-dimensional flow past airfoil sec:ions and the flow pattern is essentially different from that of straight wings, within the range of aspect ratios as used in airplanes. The leading edges of delta wings are also lateral edges. Thus, the lift drag ratio at subsonic speeds is low. Their leading edges are highly swept so that the aspect ratio is usually small. Rather, delta wings are primarily designed for supersonic speeds. Such wings would be impractical, however, because of wing-tip stalling and low lift drag ratios at subsonic speeds. At least in larger aspect ratios they can be considered to be wings with zero taper ratio (pointed wing tips) and with a swept-back 4 chord line. Triangular wings with a straight trailing edge (point flying first) are called delta wings, according to their resemblance with the Greek letter A.
