  • Patent number: 10240461
    Abstract: A stator rim structure for a gas turbine engine comprises a stator having an end wall and a discourager defining a channel therebetween. The end wall is adjacent to a hot gas flow and the discourager is adjacent to a purge flow. A rotor has an angel wing extending into the channel. At least one supply passage is disposed within the stator and extends through the discourager and at least one aperture fluidly couples the supply passage with the channel. A flow of cooling air is fed from the supply passage into the aperture and into the channel to form a fluidic dam discouraging ingestion of the hot gas flow.

  • Patent number: 9509466
    Abstract: In a network, a first network station (61) communicates with a second network station (65) using a first channel (45) from a plurality of channels. The first channel (45) has a central frequency (46). A third network station (62) communicates using a sub-channel (55) of the first channel (45). The sub-channel overlaps the first channel (45). The sub-channel (55) has a center frequency (56) that varies sufficiently from the center frequency (46) of the first channel (45) so that the first network station (61) and the second network station (65) do not lock onto packets transmitted from the third network station (62). The center frequency (56) of the sub-channel (55) is closer in frequency to the center frequency (46) of the first channel (45) than to a center frequency of any other channel in the plurality of channels.

  • Patent number: 8467978
    Abstract: A method and apparatus for inspecting a surface of an object. Data from measuring the surface of the object is obtained to form surface data for the object. A range of frequencies for features on the object is selected based on a range of distances between adjacent peaks for the features. The features are formed by a tool moving along a number of paths. Desired surface data for the features is obtained from the surface data using the range of frequencies selected. A determination is made as to whether the desired surface data for the features meets a policy specifying a desired surface for the object. In response to an absence of a determination that the desired surface data for the features meets the policy, the object is reworked.

  • Patent number: 8417485
    Abstract: The advantageous embodiments provide a computer implemented method, apparatus, and computer program product for constructing a computer aided design model. User input is received that contains a callback function and a required accuracy. The callback function prescribes a procedurally defined geometry and the required accuracy specifies the degree of accuracy needed for the computer aided design model. The callback function is sampled at a number of points to form sampled points and a candidate curve is constructed that approaches the sampled points. A determination is made as to whether the candidate curve meets the required accuracy.

  • Publication number: 20090152392
    Abstract: Lofting of a Blended Wing Body air vehicle is accomplished by first determining the required payload volume of the air vehicle. The payload volume is then analyzed to determine a list of corner points of the payload volume. The list of points is passed to a Loft Module as keep-out points and a body portion of the blended wing body is established using a faceted minimum volume which encloses all of the provided keep-out points. A trapezoidal wing shape and size is then determined to accommodate aerodynamic performance requirements. A leading edge of the body portion and trapezoidal wing leading edge are trimmed and a trailing edge of the body portion and trapezoidal wing trailing edge are blended. A leading edge elevation is established and with leading edge radius as an input all other point coordinates and all tangents and remaining curvatures to smoothly enclose the payload volume in a first set of aerodynamic sections are defined.

  • Patent number: 7518609
    Abstract: According to one aspect of exemplary embodiments of the present invention, a method is provided for modeling a transition between adjoining surfaces. The method includes determining a curve of intersection of two adjoining surfaces, where the curve includes a plurality of points. For each of at least some of the points, the method includes selecting a point of the curve of intersection, and determining end points of a section of the transition located at the selected point, where each end point is located on a respective one of the adjoining surfaces. The method also includes determining a shape of the section of the transition, where the shape of the section for each of at least some of the points models the transition between the adjoining surfaces. The transition is curvature continuous with a first curvature at the end points and a second, different curvature at a portion therebetween.

  • Patent number: 7333109
    Abstract: A system, method and computer program product are provided for modeling at least one section of a curve. Each section can be modeled by initially providing a pair of positions (fi, fi+1) of the section of the curve including associated directions (di, di+1) and curvatures (?i, ?i+1). Then, points b0, b1, b2, b3 and b4 can be identified based upon the pair of positions (fi, fi+1) and associated directions (di, di+1) and curvatures (?i, ?i+1). Thereafter, a quartic interpolant p(t) can be determined over an interval (i?t?i+1) based upon points b0, b1, b2, b3 and b4 to thereby model the section of the curve. The quartic interpolant can be determined such that the interpolant p(t) has a position, direction and curvature equal to fi, di and ?i, respectively, at t=i, and the interpolant p(t) has a position, direction and curvature equal to fi+1, di+1, and ?i+1, respectively, at t=i+1.
