 | Motivation to expand the understanding of a helicopter rotor descending into the vortex ring state (VRS) stems from the aircraft mishaps that have plagued the helicopter community. The V-22 has become the most recent victim of encounters with VRS. The onset of VRS is associated with the collapse of the helical vortex wake in the plane of the rotor. The resulting wake disturbances develop an irregular and aperiodic flow. Rotor ... |

| Supersonic impinging jet flows, such as those that occur in the next generation of STOVL aircraft, are highly unsteady due to the presence a feedback loop. This results in large dynamic loads on the nearby aircraft structures and surfaces and diminishes aircraft performance. In this study, a unique active control technique that utilizes arrays of supersonic microjets (less than or equal 400 micrometers) around the periphery of the main jet ... |

Information superiority is emerging as a newly recognized, and more intense, area of competition. In the struggle for information on the battlefield, control of the electromagnetic spectrum has proven to be of extreme importance in modern conflicts. As forces enter into battle with more ... |

| Experimental studies of supersonic impinging jet flows suggest that they are greatly influenced by the flow-acoustic interactions through a feedback mechanism. The self-sustained oscillations of the jet column observed in theses flows result in high velocities in the ambient medium induced by the large-scale coherent vortical structures in the jet shear layers. As a consequence, the suck down force on the surface from which the jet is issuing can reach ... |
