ASSEMBLY AND METHOD OF FORMING GAS TURBINE ENGINE COMPONENTS
A mounting plate for forming a gas turbine engine component according to an example of the present disclosure includes, among other things, a plate body defining an abutment dimensioned to mate with a forming die. The plate body defines at least one internal cooling circuit. The at least one internal cooling circuit includes a passageway having an intermediate portion interconnecting inlet and outlet portions. The intermediate portion is dimensioned to follow a perimeter of the abutment. The intermediate portion includes a plurality of fins extending partially from a first sidewall towards a second sidewall opposed to the first sidewall. A method of forming a gas turbine engine component is also disclosed.

METHOD OF FORMING COOLING HOLES
An apparatus and method regarding forming a cooling hole in a component for a turbine engine, with the component held in a hole-forming machine with a laser carried on a multi-axis carriage and defining an optical path, the method comprising forming a set of cooling holes in the component with a laser mounted to the multi-axis carriage, estimating a total airflow through the set of cooling holes based on a set of data regarding the flow effectiveness of the set of cooling holes, and forming a second set of cooling holes with the laser.
MANUFACTURING THIN-WALLED CASTINGS UTILIZING ADAPTIVE MACHINING
A method of manufacturing a casting is provided and includes establishing desired dimensions of a nominal casting, executing a casting process to produce multiple actual castings with each of the multiple actual castings having respective dimensions that differ from each other and from the desired dimensions of the nominal casting and engaging one or more tools to adaptively machine, without rigidly-programmed toolpaths, each of the multiple actual castings to reduce the respective differences between the actual dimensions of each of the multiple actual castings and the desired dimensions.
CYLINDRICAL TUBE FORMATION
Tube forming methods can be used for efficient transition in the production of tubes having varying thickness. Material used to form consecutive tubes may have the same thickness along a separation plane separating a first discrete section from a second discrete section of the material, and the first discrete section and the second discrete section may each have varying thickness in a feed direction of the material. With such a thickness profile, the first discrete section of the material may be formed into a first cylinder having varying thickness and separated from the second discrete portion as the second discrete section is formed into a second cylinder having varying thickness. In particular, the transition between the first cylinder and the second cylinder may be achieved without scrap and/or interruption, resulting in cost-savings and improvements in production throughput associated with forming tubes having varying thickness.
NUTRITIONAL SUPPLEMENT FOR INCREASING COGNITIVE FUNCTIONS
The invention provides compositions and methods that are effective to improve NO production in vivo and/or to increase NO levels in blood. Such compositions and methods are useful to increase oxygenation of the brain and to improve cognitive function.

Method of producing a gas turbine engine component
A method of producing a gas turbine engine fan blade having a geometric configuration is provided. The method includes: plastically deforming an initial substrate comprised of a first metallic material into a formed substrate; depositing a second metallic material onto the formed substrate using an additive manufacturing process to produce a blade blank, which depositing includes: additively depositing second metallic material to at least one of the first face surface or the second face surface of the formed substrate adjacent the first end surface, to form a root portion; additively depositing second metallic material to at least one of the first face surface or the second face surface of the formed substrate between the root portion and the second end surface to form an airfoil portion; and shaping the blade blank into the geometric configuration.
