Abstract: A method of laser bond inspection is provided. The method includes applying a thermochromatic energy-absorbing material to an inspection site of a test article. The method includes delivering a first amount of energy to the inspection site using a laser. The first amount of energy generates stresses in the test article. The method includes absorbing the first amount of energy into the thermochromatic energy-absorbing material to produce an observable thermal response that correlates to the first amount of energy.

Abstract: A plurality of micro-electro-mechanical system (MEMS) transducers in a phased array are coupled to a flexible substrate using carbon nanotubes (CNTs) for conformal ultrasound scanning. Each transducer comprises a cantilever, magnetic material deposited on the cantilever, and a solenoid positioned relative to the magnetic material. The carbon nanotubes are grown on the cantilever and mechanically couple the transducer to one side of the flexible substrate. The other side of the flexible substrate is applied to a surface of a part under inspection, and the transducers are electrically connected to a processer to cause movement of the cantilevers when the solenoids are energized by the processor. The movement of the cantilevers results in movement of the carbon nanotubes, which imparts a force to the flexible substrate that results in ultrasound waves, which permeate the part. Returns from the ultrasound waves are interpreted by the processor to generate images of the part.

Abstract: A system for the detection of foreign object debris material on a surface of a composite part being manufactured. A platform is configured to move over the surface. A thermal excitation source is fixed to the platform and configured to direct infrared radiation across the surface. An infrared camera is also fixed to the platform and configured to scan the surface as the platform moves over the surface to detect and output a signal proportional to infrared radiation emitted by the surface and/or by any foreign object debris material on the surface in response to the infrared radiation from the excitation source. A controller is coupled to the excitation source and to the infrared camera and is configured to compare the signal from the infrared camera with a first predetermined threshold signal to detect if any foreign object debris material is located on the surface.

Abstract: A system and method for the detection of foreign object debris materials or defects on and/or under a surface (e.g., outer ply) of a composite part being formed by a composite layup machine. A gantry moves over the composite part along a predetermined length thereof. A thermal excitation source fixed to the gantry directs infrared radiation across the width of the surface of the composite part. A infrared camera fixed to the gantry a predetermined distance away from the thermal excitation source scans the surface as the gantry moves to detect and output scan information thereof. A controller is coupled to the thermal excitation source and to the infrared camera. The controller processes the sequence of infrared images to identify a foreign object debris material or defect located on and/or under the surface.

Abstract: Described herein is a motor comprising a first rotatable member and an anchor, spaced apart from the first rotatable member. The motor also comprises a belt, in tension about the first rotatable member and the anchor. The belt is co-rotatably engaged with the first rotatable member. Further, the belt is made from a shape-memory alloy. Additionally, the motor comprises a thermal regulation device, positioned between spaced-apart first and second portions of the belt. The thermal regulation device is also configured to concurrently cool the first portion of the belt to contract the first portion of the belt and heat the second portion of the belt to expand the second portion of the belt. Concurrent contraction and expansion of the first and second portions of the belt cause rotation of the belt.

Abstract: Embodiments of the present disclosure provide systems and methods for detecting one or more thermal and/or mechanical properties of a structure. The method may include forming one or more test structures from a material that forms the structure, generating and storing calibration data determined from the one or more test structures, emitting X-ray radiation into the structure, detecting X-ray scatter from the structure, and determining the one or more properties of the structure based on the detected X-ray scatter and the calibration data.

Abstract: A portable x-ray backscattering imaging system for creating a backscatter image representing an object is disclosed. The portable x-ray backscattering imaging system may include a drum, a radioactive source, a plurality of backscatter detectors, and a portable exterior shield. The drum may be rotatable about an axis of rotation at a rotational speed. The radioactive source may be connected to the drum and configured to generate x-rays. The plurality of backscatter detectors may be configured to detect backscattering radiation created as the x-rays generated by the radioactive source scatter back from the object. The portable exterior shield may enclose the drum. The exterior shield may be constructed of a material that substantially blocks the x-rays and defines a window that allows for the x-rays to pass through.

Abstract: Provided are methods and systems for non-destructive testing of parts while these parts are being fabricated and/or operated. A part has hybrid spectral sensors embedded within and bonded to one or more other components of the part. A hybrid spectral sensor may include two different structures. A first structure of the sensor provides a first spectral response when exposed to an excitation radiation. A second structure forms a Faraday cage around the first structure and blocks the excitation radiation to the first structure and/or blocks the first spectral response emitted by the first structure if the first structures gets exposed to the excitation radiation. The second structure may be bonded to one or more components of the part, such as a matrix resin, and may change its coverage of the first structure during fabrication and/or operation of the part thereby altering its blocking characteristics.
