20130193620 | MULTI-DIMENSIONAL COMPONENT BUILD SYSTEM AND PROCESS - An example multi-dimensional component building system includes a first chamber having at least one base, a second chamber adjacent to and in fluid communication with the first chamber through a first door, and a third chamber adjacent to and in fluid communication with the second chamber through a second door. The second chamber is fluidly sealed from the first chamber if the first door is in a closed position. The second chamber includes a directed heat source, a build-up material and is configured to receive the at least one base if the fluid parameters of the first chamber and second chamber are approximately equal. The third chamber is fluidly sealed from the second chamber if the first door is in a closed position. The third chamber is configured to receive the at least one base, having a formed component disposed thereon, if the second door is in an open position. | 08-01-2013 |
20130236323 | LEADING EDGE PROTECTION AND METHOD OF MAKING - A method of forming a leading edge protection component includes depositing particles using a cold spray process on a mandrel to form a leading edge protection component; and removing the leading edge protection structure from the mandrel. The leading edge protection can be formed in one or more pieces and involve using one or more mandrels. | 09-12-2013 |
20130251536 | HYBRID AIRFOIL FOR A GAS TURBINE ENGINE - A hybrid airfoil for a gas turbine engine according to an exemplary embodiment of this disclosure can include a leading edge portion, a trailing edge portion, and an intermediate portion between the leading edge portion and the trailing edge portion. The leading edge portion can be made of a first material, the trailing edge portion can be made of a second material, and the intermediate portion can be made of a third material. At least two of the first material, the second material and the third material are different materials. | 09-26-2013 |
20130294901 | METAL POWDER CASTING - A method of component forming according to an exemplary aspect of the present disclosure includes, among other things, positioning a metal powder in a mold cavity, melting the metal powder within the mold cavity, and cooling the melted metal powder to form a component. | 11-07-2013 |
20150069668 | MULTI-DIMENSIONAL COMPONENT BUILD SYSTEM AND PROCESS - An example multi-dimensional component building system includes a first chamber having at least one base disposed therein, a second chamber adjacent to and in fluid communication with the first chamber through a first door, and a third chamber adjacent to and in fluid communication with the second chamber through a second door. The second chamber is fluidly sealed from the first chamber if the first door is in a closed position. The second chamber is configured to receive the at least one base via a first transfer mechanism if the fluid parameters of the first chamber are approximately equal to the fluid parameters of the second chamber. The second chamber includes a directed heat source and a build-up material configured to form a component on the at least one base by melting or sintering. The third chamber is fluidly sealed from the second chamber if the first door is in a closed position. The third chamber is configured to receive the at least one base, having a formed component disposed thereon, via a second transfer mechanism if the second door is in an open position. The fluid parameters of the second chamber are not substantially affected by fluid communication with the first chamber or the third chamber. | 03-12-2015 |
