Abstract: A nondestructive multispectral vibrothermography inspection system includes a fixture to retain a component, an ultrasonic excitation source directed toward the component retained within the fixture, a laser Doppler vibrometer directed toward the component retained within the fixture, and a multispectral thermography system directed toward the component retained within the fixture. A method for nondestructive multispectral vibrothermography inspection of a component, includes generating ultrasonic excitations in a component over a broad range of frequencies; determining a spectral signature in the component from the excitations; comparing the spectral energy signature against database 270 of correlations between vibrational frequencies of a multiple of components and the spectral energy distribution thereof, and classifying the component based on the database data.

Abstract: An additive manufacturing system includes an ultrasonic inspection system integrated in such a way as to minimize time needed for an inspection process. The inspection system may have an ultrasonic phased array integrated into a build table for detecting defects in each successive slice of a workpiece and such that each slice may be re-melted if and when defects are detected.

Abstract: A aerodynamic particle separator for an Additive Manufacturing System (AMS) has an air supply device to entrain a mixed powder in an airstream flowing through a housing. Each particle in the mixed powder is imparted with a momentum dependent upon the particle weight and size. Utilizing this momentum characteristic, the heavier particles are capable of crossing streamlines of the airstream at a bend portion of the housing and the lighter particles generally stay within the streamlines. Utilizing this dynamic characteristic, the particles of specific weight ranges are collected through respective offtake holes in the housing and controllably fed to a spreader of the AMS.

Abstract: A method of forming a metal component having different regions containing different grain sizes and in porosities is by additive manufacturing. The method includes spreading a layer of starting powder on a temperature controlled moveable platform in a heated chamber with atmosphere and temperature control. Selected areas of the powder are melted and solidified with a computer controlled focused energy beam. The cooled platform is then indexed down and the process repeated. The grain size of the melted and solidified region can be controlled by the cooling rate during solidification which, in turn is controlled by the temperature of the chamber and the temperature of the cooled moveable platform.

Abstract: A method for modeling additive manufacturing of a part, includes (i) constructing a model for estimating output of a simulated additive manufacturing process based upon part design, energy equation and at least one additional relationship selected from the group consisting of phase field equation, concentration equation and stress equation; (ii) entering process operating parameters into the model to produce an output; (iii) comparing the output to acceptance criteria to determine whether the output is acceptable or unacceptable; (iv) for acceptable output, adding operating parameters which resulted in the acceptable output to a process map for additive manufacturing the part; and (v) repeating steps (ii) through (iv) for different operating parameters until the process map is complete.

Abstract: A system and method for prognostic health monitoring of thermal barrier coatings is provided. The system may comprise monitoring a thermal barrier coated gas turbine engine component, and measuring the infrared radiation emitting from the component. The measured thermal radiation data may be analyzed and compared to known material thermal radiation data in order to determine the health of the thermal barrier coating. The compiled comparison results may be compared against a historical statistical study to then determine the overall health of the thermal barrier coating. The system may comprise generating a health monitoring alert in response to the health of the thermal barrier coating indicating an imminent failure.

Abstract: A method of refurbishing a gas turbine engine rotor is disclosed and includes an initial step of inspecting a rotor for defects such as cracks. A strain is then generated around any detected cracks in the rotor to create enhanced plasticized zones about the detected defects that delay defect propagation. Strain is generated by rotating the rotor at speeds greater than operational speeds to induce the desired strain and delay the propagation of defects.
