  • Patent number: 11834170
    Abstract: An airfoil surface skin, comprising a network of a solid material, embedded in a base of deformable solid material. Fluid pressure applied to the interface between the network and the surrounding embedding material, opens an internal network of channels by viscous peeling of the surrounding solid from the network. The network is offset from the centerline the surround material, such that pressure driven viscous flow through the narrow channels generates two types of deformation of the skin—an in-plane elongation and a curvature of the skin plane itself. The shape of the internal solid core element and its material, and the material of the encompassing solid are chosen to achieve a desired integral structural rigidity. The injected fluid pressure determines the extent of extension and bending. Use of this skin enables shape amending airfoils having reduced drag compared with similar airfoils having conventional flap mechanisms.

  • Patent number: 10450051
    Abstract: A pressurized, fluid-filled channel network embedded in an elastic structure, asymmetrically to the neutral plane, is used to create a deformation field within the structure by the pressurization of the embedded fluidic network, which can be applied in accordance with external forces acting on the structure. The deformation of the structure resulting from the liquid pressure and geometry of the network is related to a continuous deformation-field function. This enables the design of networks creating steady arbitrary deformation fields as well as to eliminate deformation created by external time varying forces, thus increasing the effective rigidity of the beam. By including the effects of the deformation created by the channel network on the beam inertia, the response of the beam to oscillating forces can be modified, enabling the design of channel networks which create pre-defined oscillating deformation patterns in response to external oscillating forces.

  • Publication number: 20140162048
    Abstract: Multi-layer fabrics and products incorporating the same are described in which the fabrics are configured to provide asymmetric resistance to liquid flow from one side of the fabric to the other. In garments or other products worn by a user, the effect can be utilized to prevent penetration of liquids (e.g., rain droplets) and contact of liquids from the exterior with the user's skin while allowing for extraction of droplets (e.g., sweat) in contact with an inner layer of the fabric out of contact with the skin and accelerating their evaporation. Medical and industrial applications of the fabric are contemplated as well.
