Comment on " Convergence Proof of Discrete-Panel Wing Loading Theories"

Abstract

maximum tangential (swirl) velocities in the flow. Based on their own study of mass injection and the results of other researchers, Mason and Marchman2 concluded that the introduction of turbulence into the vortex by virtually any means is the dominant factor in tangential velocity reduction and the spreading of the core. The present research seems to substantiate this conclusion. These results show that vortex dissipation effects similar to those produced by mass injection can be realized without either bleeding power from the engines or using auxiliary power. In fact, using the spinning blade concept, the vortex dissipator may actually be used to produce power. Of course, such results are never free and the effects of these modifications on the wing aerodynamic characteristics as well as the vortex must be studied. The present study seems to indicate that such modifications can significantly reduce the vortex Lazard to trailing aircraft without the use of auxiliary or other power and with few, if any, detrimental effects on the wing aerodynamics.
