,Abgekürzte, vereinfachte Darstellung,eak velocities are shown to occur in small intense vortices which are separate from the main tip vortices These exist up to 30 seconds after generation. The main tip vortices are shown to have a core size which is roughly of the size anticipated but whose diameter does not increase significantly upNEG 发表于 2025-3-29 01:21:32

Das Maschinenzeichnen des Konstrukteurs theory show that the stronger vortex moves from the tip of the wing to the hinge of the drooped tip as the droop angle increases. Experimental results on model wings are given which present the strength and the induced velocity profiles of the rolled-up vortex as a function of tip geometry.

Anordnung der Ansichten und Schnitte,straight and swept wings are described. The results of observations on the formation of loops in a vortex wake, on the behaviour of the wakes close to the ground and on the development of the wake from a slender wing are, given in some detail.无意 发表于 2025-3-29 13:29:36

Das Maschinenzeichnen des Konstrukteursuft grid and smoke. Preliminary studies showed that the introduction of a bluff body into the trailing vortex downstream of the wing resulted in modification of the vortex. Further studies showed that a small vertical panel, termed a vortex dissipater, mounted on the wing upper surface near the wingcraving 发表于 2025-3-29 21:32:08
Gesamtzeichnungen und sonstige Zeichnungen,aft response results were reported at the end of Session VI of the Symposium..Calculations of the sinuous instability of a trailing pair are extended, using a nonlinear vortex modeling technique, and the effects of initial parameters are examined, particularly the initially assumed wavelength.
