Low-Speed Lift Enhancement of the Vortex-Lift Waverider During Pitching Oscillation

Journal of Aircraft
The vortex-lift waverider presents great potentiality in the design of wide-speed-range hypersonic vehicles. However, its constrained lift characteristics, resulting from vortex breakdown at low-speed, high-angle-of-attack (AOA) conditions, restrict its capability for horizontal takeoff and landing.

Theoretical and Experimental Investigations of Vortex Lift Control by Spanwise Blowing. Volume 2. Three-Dimensional Theory for Vortex-Lift Augmentation

1973
Abstract : A theoretical description is presented on the experimentally observed phenomenon of wing leading-edge vortex lift control by spanwise mass injection. The vortex and jet initial source/sink strengths and locations are established by a conformal mapping solution, and used as starting conditions for an iterative vortex-lattice simulation.

On Cavitation Produced by a Vortex Trailing From a Lifting Surface

Journal of Basic Engineering, 1962
An experimental and analytical study is made of cavitation produced by the vortex system trailing from elliptic, rectangular, and delta wings. It is found that the inception of this type of cavitation depends upon the boundary-layer thickness of the lower surface of the wing tip.

Motion of a buoyant vortex ring opposite to the lift direction

Doklady Physics, 2016
The motion of a buoyant vortex ring in the direction opposite to the lifting force of a set magnitude in a wide range of variation of its initial velocity is experimentally investigated. The dynamics of its sizes is determined; the experimental results are compared with the theoretical data for homogeneous and inhomogeneous buoyant vortices in the ...
