Systems and methods for repairing corrosion damage of a part of a thrust reverser assembly. The method includes removing the part having an inner surface and an outer surface. The method also includes removing an outer skin from the inner surface and the outer surface of the part. The method further includes installing a ply of synthetic fiber material onto an area of the inner surface or the outer surface of the part. The method also includes installing one or more doublers onto the ply of synthetic fiber material and heat curing layers of film adhesive. The method further includes applying an edge seal to gaps between the one or more doublers and the inner surface or outer surface of the part. The method also includes installing the outer skin to the inner surface and the outer surface of the part and installing the part to the thrust reverser assembly.

The present technology relates to systems and methods for reducing leaks in a system for coking coal. For example, some embodiments provide systems and method for treating a cracked or leaking surface in a system for coking coal. In particular, the present technology includes systems having one or more substances configured to reduce an airflow through one or more cracks by creating an at least partially impermeable patch. The present technology further includes methods for treating surfaces having one or more cracks to reduce an airflow through the one or more cracks.

A body panel for repairing damaged vehicle bodies including a layer assembly. The body panel makes use of a fibrous sheet that includes fiber glass, carbon fiber, or Kevlar that would be easily painted and installed to replace damaged vehicle bodies. The body panel makes great usage for repairing damaged body panels as it is strong and durable as it does not dent, it is lightweight, it is inexpensive, and it importantly does not rust.

A lock and pin for the structural and fluid tight repair of cracks not amenable to high temperature repairs or synthetic material patches. Fluid tight pins and locks seal the crack while one or more locks prevent the crack from growing. These repairs need to endure the remaining life cycle of the machinery part while withstanding all the strain, pressure, heat and expansion and contraction of the part before the crack(s) were formed. Often these cracks evolved due to engineering design flaws that will require even greater strength from these areas than when new.

The present invention is directed to in situ methods for maintaining turbine assemblies. One such method includes: disposing a maintenance apparatus on the rotor; positioning the maintenance apparatus proximate to the damaged region by rotating the rotor; and repairing the damaged region by operating a repair tool disposed on the apparatus. Another method includes: disposing a maintenance apparatus on the stator; positioning the damaged region proximate to the maintenance apparatus by rotating the rotor; and repairing the damaged region by operating a repair tool disposed on the apparatus.

A dual walled component includes a spar comprising a plurality of pedestals; a coversheet attached to a first set of pedestals from the plurality of pedestals; and a repaired coversheet portion attached to a second set of pedestals from the plurality of pedestals and to the coversheet, where the repaired coversheet portion includes a braze material.

A method for treating an internal defect in a part made of a material, involves: a) detecting and locating the internal defect in the part; b) defining, inside the part, at least one target volume which at least partially includes the defect; c) for each target volume, simultaneously irradiating the target volume by at least two beams which converge in the target volume and are continuous, whereby a treated area is obtained. The energy applied to the target volume by each beam is less than a threshold energy for sintering the material, and the sum of the energies applied to the target volume by each of the beams is greater than or equal to a transformation threshold energy that corresponds to the threshold energy for sintering or melting the material; the material of the part is partially transparent to said beams.

A metallic product is produced by an additive manufacturing method. A device for practicing has a controller with a stored instruction set for implementing the manufacturing of the metallic product. The metallic product is manufactured in a piece- wise or layer-wise manner on a target platform by a print head that is in two-way communication with the controller. The print head operates on a momentum transfer technique in which pulsed energy from an impulse source is used to launch pieces of metal toward the target platform, the pieces of metal bonding at the target platform to manufacture the metallic product.
