  • Patent number: 6855428
    Abstract: The present invention is a composite material and process to produce same. That material comprises a fibrous structure which is initially predominantly coated with elemental carbon; that fibrous structure is then subsequently predominantly coated with at least one ceramic material, e.g., boron carbide, which is non-reactive with silicon. The composite material also comprises a silicon matrix which is continuous and predominantly surrounds the fibrous structure, which has been initially predominantly coated with elemental carbon and subsequently predominantly coated with at least one ceramic material. The matrix which has a fine grain crystalline structure of predominantly 20 microns or less in size. The at least one ceramic material is discontinuous within that matrix. The fibrous material pulls out of the elemental carbon, which initially predominantly coats that fibrous structure, when the composite is subjected to fracture.

  • Patent number: 6818876
    Abstract: A method and apparatus for producing a scintillation-immune adaptive optics reconstructor is disclosed. The present invention includes a wavefront sensor (70) which determines illumination slope and amplitude of a number of subapertures (75). The slope and amplitude information is coupled to a slope weighting function (90), which weights the slopes of each subaperture (75) according to the amplitude of illumination of each subaperture. The present invention determines the variation in light amplitude received by the subapertures (75) and determines a slope of the light amplitude variation. The signal gain of the imaging system is then adjusted depending on the slope of the light amplitude variation, thereby yielding a closed-loop system that compensates for amplitude disturbances caused by scintillations in the images received by the imaging system (10).

  • Patent number: 6520452
    Abstract: A deicer is provided for breaking up and removing accumulated ice on an airfoil surface. The deicer includes a bondside surface that is bonded to the airfoil surface, a breezeside surface on which the ice will accumulate, and passage-defining surfaces therebetween. The passage-defining surfaces define a plurality of expansible and contractible inflation passages and include a moisture-impervious coating whereby moisture within the inflation passages will not be absorbed by the surfaces. The bondside, breezeside and passage-defining surfaces may be contained on a deicer panel and means may be provided for introducing inflation fluid to and evacuating inflation fluid from the passages to expand and contract the inflation passages to break up and remove the accumulated ice.

  • Publication number: 20020136982
    Abstract: The present invention relates to a radiation sensitive photoresist composition comprising a photoacid initiator and a polycyclic polymer comprising repeating units that contain pendant acid labile groups. Upon exposure to an imaging radiation source the photoacid initiator generates an acid which cleaves the pendant acid labile groups effecting a polarity change in the polymer. The polymer is rendered soluble in an aqueous base in the areas exposed to the imaging source.

  • Patent number: 6443394
    Abstract: An airfoil device (10) for attachment to the wing (14) of an aircraft (12). The airfoil device (10) has a chamber (30) which is inflatable to provide a lift-enhancing airfoil geometry to the wing (14) and other chambers (32) which are inflatable to provide deicing forces to remove ice accumulation on the wing (14). When installed on the wing (14), the airfoil device (10) closely conforms to the wing's airfoil geometry (e.g., low camber, sharp leading edge) when the lift-enhancing chamber (30) and the deicing chambers (32) are in a deflated condition. The lift-enhancing chamber (30) can be inflated during take-off and landing to provide a high camber and less sharp airfoil geometry. If ice accumulates on the wing (14) during high speed flight, the deicing chambers (32) can be repeatedly inflated/deflated for ice removal purposes.

  • Patent number: 6439505
    Abstract: A deicer (10) for a radome (12) includes an active portion (16) through which transmission occurs and a non-active portion (18) which is attached to an aircraft (14). The deicer (10) comprises a cap portion (20) covering the active portion (16) of the radome (12) but unattached thereto. The cap portion (20) comprises layers (36, 38) defining inflatable/deflatable chambers (24), the layers both being made of non-extensible material such as square woven nylon fabric. When the chambers (24) are inflated, the inner layer (38) lifts off of the active portion (16) of the radome (12). The deicer (10) can additionally comprise a skirt portion (22) which is stretchable to accommodate the inflation of the chambers (24).
