    摘要: A fluid control system includes a dielectric-barrier discharge (DBD) device, and processing circuitry. The processing circuitry is configured to obtain a streamwise length scale of a fluid flowing over a surface. The processing circuitry is also configured to obtain a convective time scale of the fluid flowing over the surface. The processing circuitry is also configured to operate the DBD device, based on the streamwise length scale and the convective time scale, to adjust a flow property of the fluid.

    摘要: A fluid control system includes a deformable surface that covers a body in at least a first and second direction. The first direction is orthogonal to the second direction. The deformable surface includes a bottom side that faces the body and a top side that is opposite the bottom side. The fluid control system also includes at least one deformer between the deformable surface and the body. The at least one deformer is configured to modify a boundary layer of a fluid that is flowing over the deformable surface by selectively deforming the top side of the surface.

    摘要: A system and method is described generally for providing a high altitude conduit the high altitude conduit includes a first material layer forming an elongated duct. The high altitude conduit also includes a second material layer outside the first material layer. The second material layer defines a space between the second material layer and the first material layer. A gas has a density that is less dense than that of the atmosphere outside of the second material layer. The gas is disposed in the space between the first and the second layer. An introducer is configured to provide the gas into the space between the first material layer and the second material layer. The gas causes the conduit to extend in an approximately upright orientation.
