| Popis: |
This paper considers the vortex ring state, a flow condition usually associated with the descent of a rotor into its own wake.\ud The phenomenon is investigated through experiments on simple rotor systems, and a comparison is then made with observations\ud of a flow generated by a specially designed open core, annular jet that generates a mean flow velocity profile similar to the mean\ud flow in a rotor wake in hover. In an experimentally simulated descent, the jet flow generates a flow state that shares many\ud features of the rotor vortex ring state. |
