Abstract
Techniques for acquiring data from aircraft components, such as turbine blades used in jet engines are provided. Specifically designed fixtures with reference points are constructed to hold the blade to be scanned. A 3D scanner is used to acquire positional data of the blade at a high resolution and this data is used to generate a 3D model. The 3D model can be used to validate, for example, that a component of an aircraft has been manufactured as designed.
Claims20
A method for developing a scanning process for acquiring three-dimensional data of blades for use in jet engine turbines, each of the blades including a plurality of cooling holes, the method comprising:
- building a fixture for a blade based on a type of design for the blade, wherein the structure of the fixture is based, at least in part, on position and/or angularity of at least some of the cooling holes in the blade;
- locating a plurality of reference points on the fixture;
- generating a scanning template that includes values for a plurality of parameters;
- securing the blade to the fixture;
- generating a measurement series that includes a plurality of data values, wherein each of the plurality of data values includes:
- 1) position data for positioning a scanner, and 2) orientation data for orienting the scanner;
- automatically controlling, based on the scanning template, the scanner to acquire 3D scan data of the blade by executing the generated measurement series;
- and
- validating the acquired 3D scan data.
A method of acquiring three-dimensional data of blades for use in jet engine turbines, each of the blades including a plurality of cooling holes, the method comprising:
- selecting, from among a plurality of differently structured fixtures, a fixture for a blade based on a type of design for the blade, wherein the structure of the fixture is based, at least in part, on position and/or angularity of at least some of the cooling holes in the blade;
- loading, based on type of design for the blade, a scanning template that includes values for a plurality of parameters;
- securing the blade to the fixture;
- loading, from a data file, a measurement series that includes a plurality of data values, wherein each of the plurality of data values includes:
- 1) position data for positioning a scanner, and 2) orientation data for orienting the scanner;
- automatically controlling, based on the scanning template, the scanner to acquire 3D scan data of the blade by executing the generated measurement series;
- automatically performing a validation process to determine, based on the 3D scan data, that at least one of the plurality of cooling holes is within a corresponding manufacturing tolerance.
A system for acquiring positional data of different types of blades that are used in jet engine turbines, with each of the blades including a plurality of cooling holes, the system comprising:
- a scanner that includes a projector, a camera, and a lens;
- and
- a computer system that includes at least one hardware processor that is coupled to the scanner, the computer system configured to perform operations comprising:
- loading, based on a type of design for a blade that is to be scanned, a scanning template that includes values for a plurality of parameters, wherein the scanning template includes parameters for a plurality of reference points that are associated with a first fixture designed for the type of blade to be scanned, the first fixture being among a plurality of different fixtures that are each associated with a different type of blade for which positional data can be obtained by the system;
- loading, from a data file, a measurement series that includes a plurality of data values, wherein each of the plurality of data values includes:
- 1) position data for positioning the scanner, and 2) orientation data for orienting the scanner,
- automatically controlling, based on the scanning template, the scanner to acquire 3D scan data of the blade by executing the generated measurement series, and
- automatically performing a validation process to determine, based on the 3D scan data, that at least one of the plurality of cooling holes is within a corresponding manufacturing tolerance.
