The Symphony SA-160 was designed with two unusual vortex generators on its wing to ensure aileron effectiveness through the stall. A vortex generator (VG) is an aerodynamic device, consisting of a small vane usually attached to a lifting surface (or airfoil, such as an aircraft wing) [1] or a rotor blade of a wind turbine. [2]
Vortilons consist of one or more flat plates attached to the underside of the wing near its leading edge, aligned with the flight direction. [6] When the speed is reduced and the aircraft approaches stall , the local flow at the leading edge is diverted outwards; this spanwise component of velocity around the vortilon creates a vortex streamed ...
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. [7] Wings which generate ...
A dogtooth is a small, sharp zig-zag break in the leading edge of a wing. It is usually used on a swept wing, to generate a vortex flow field to prevent separated flow from progressing outboard at high angle of attack. [1] The effect is the same as a wing fence. [2] It can also be used on straight wings in a drooped leading edge arrangement.
This necessitated a wing redesign incorporating a cranked and drooped leading edge and vortex generators to avoid the onset of compressibility drag, which would have restricted the maximum speed. [22] This wing modification resulted in the "phase 2" wing which was first investigated on Avro 707A WD480.
By obstructing span-wise airflow along the wing, they prevent the entire wing from stalling at once, as opposed to wingtip devices, which increase aerodynamic efficiency by seeking to recover wing vortex energy. As a swept-wing aircraft slows toward the stall speed of the wing, the angle of the leading edge forces some of the airflow sidewise ...
