Four basic configurations which have used vortex lift are, in chronological order, the 60-degree delta wing; the ogive delta wing with its sharply-swept leading edge at the root; the moderately-swept wing with a leading-edge extension, which is known as a hybrid wing; and the sharp-edge forebody, or vortex-lift strake.

A leading-edge root extension (LERX) is a small fillet, typically roughly triangular in shape, running forward from the leading edge of the wing root to a point along the fuselage. These are often called simply leading-edge extensions (LEX), although they are not the only kind. To avoid ambiguity, this article uses the term LERX.
Vortilons can be seen projecting from underneath the center leading edge of the wings of this Hawker 850XP. Vortilons are fixed aerodynamic devices on aircraft wings used to improve handling at low speeds. [1] [2] The vortilon was invented [3] by aerodynamicists working at Douglas Aircraft who had previously developed the engine pylons for the ...
The leading edge is the part of the wing that first contacts the air; [1] [2] alternatively it is the foremost edge of an airfoil section. [3] The first is an aerodynamic definition, the second a structural one.
For example, jet aircraft with leading edge defects can carry greater payloads at faster speeds and higher altitudes, [1] allowing for greater economic efficiency in the aeronautical field. While these effects are found in many aquatic animals and birds, scaling these designs up to industrial application brings forward another set of issues ...
Basic metal-sparred wing using a honeycomb 'D' box leading edge. A typical metal spar in a general aviation aircraft usually consists of a sheet aluminium spar web, with L- or T-shaped spar caps being welded or riveted to the top and bottom of the sheet to prevent buckling under applied loads.
