  • Patent number: 12319433
    Abstract: A method of determining the steering angle of a landing gear assembly of an aircraft is disclosed including scanning the landing gear assembly with a lidar system to generate a set of three-dimensional position data points, each position data point including a set of three orthogonal position values. A two-dimensional image from the set of three-dimensional position data points, by converting a position value of each of the three-dimensional position data points to an image property value of a set of image property values. A boundary of an area of the two-dimensional image of which each position data point has the same image property value is identified, where the area corresponds to a component of the landing gear assembly. The steering angle of the landing gear assembly is then determined from the shape and/or orientation of the identified boundary.

  • Patent number: 12319434
    Abstract: A method of determining the position of one or more components of a landing gear assembly of an aircraft is disclosed including scanning the one or more components with a lidar system to generate a set of position data points, each position data point comprising a set of three orthogonal position values. The position data points are partitioned into one or more clusters using a distance metric. Each cluster is determined to represent a component of the landing gear assembly. The position of the components are then determined from the position data points in the clusters. The value of the distance metric for a first position data point and a second position data point is representative of the difference between a first position value of the three orthogonal position values of the first position data point and the corresponding first position value of the three orthogonal position values of the second position data point.

  • Publication number: 20240253817
    Abstract: A computer-implemented method of determining a position of a component of an aircraft landing gear assembly. The method includes obtaining an image of the aircraft landing gear assembly; determining a region of interest within the image, the region of interest contains the component of the aircraft landing gear assembly; calculating a coordinate of a centroid of the bounding box and comparing the coordinate of the centroid to a corresponding predetermined threshold coordinate to determine the position of the component of the aircraft landing gear assembly.

  • Publication number: 20240253815
    Abstract: A method of determining configuration status of a component of an aircraft landing gear assembly. The component with a lidar system is scanned to generate a set of position data points. A subset of the position data points is determined, the subset having position data points corresponding to positions in a predetermined region of the landing gear assembly, the predetermined region including a part of the component. The representative position point of the subset of position data points is determined, and it is determining if the position is beyond a predetermined threshold position. If the point is beyond the predetermined threshold position, a signal indicating the component of the landing gear assembly has a first configuration status is output, and if the representative position point is not beyond the predetermined threshold position, a signal indicating the component of the landing gear assembly has a second configuration status is output.

  • Publication number: 20240253818
    Abstract: A computer-implemented method of determining a steering angle of an aircraft landing gear is disclosed including obtaining a set of position data points, wherein the set of position data points comprises position data points of a component of the aircraft landing gear and calculating a centroid of the set of position data points. The method also includes determining an angle of an intersection between a straight line that passes through both the centroid and an axis of rotation of the aircraft landing gear and an axis that is orthogonal to a strut of the aircraft landing gear when the aircraft landing gear is at a previously known steering angle, and determining the steering angle of the aircraft landing gear based on the determined angle of intersection.

  • Publication number: 20240174381
    Abstract: A test system for modifying a graph-based trained classifier, configured to output control data for controlling the aircraft system according to a graph model representing the aircraft system. The test system is configured to obtain scenario data, control data, and validation data. The test system generates a custom loss score based on differences between the validation data and the control data and modifies the graph-based trained classifier based on the custom loss score, the scenario data, and the control data. A computer-implemented method for modifying the graph-based trained classifier and a storage medium comprising instructions to perform the method are also provided.

  • Publication number: 20230274459
    Abstract: A computer-implemented method of determining a steering angle of an aircraft landing gear including: obtaining an input image of the aircraft landing gear; comparing the input image against a plurality of reference images, the plurality of reference images comprising images of the aircraft landing gear at known steering angles; determining a most similar reference image, the most similar reference image comprising the reference image of the plurality of reference images most closely matched to the input image; and determining, based at least in part on the most similar reference image, the steering angle of the aircraft landing gear.
