Calculation of the Aerodynamic Effects of Certain Vortex Suppressing Devices.

Abstract

There has been a recent increase of interest in devices for accelerating the dissipation of wing-tip trailing vortices. A number of experimental programs have been carried out to determine the effectiveness of various devices, such as tip-mounted jets, small windmills, suitably disposed vortex generators and so on, in increasing the rate of vortex decay. Only limited attention seems to have been paid to the effects of these devices on the wing aerodynamic properties and the work that has been done appears to be entirely experimental. It is the purpose of the present paper to propose three simple mathematical models which may be used to assess many of the current suppressors, from the viewpoint of wing property modification.
