Gas turbine engine with active clearance control
14 Nov 23
A small gas turbine engine, such as is used to power a UAV, that includes at least one centrifugal compressor having an impeller with blades that form a gap between the blade tips and stationary shroud of the gas turbine engine, and where a resistance heating element, such as an impingement air manifold, is secured to or bonded to a compressor casing of the gas turbine engine in order to use heat to control the gap between the impeller blades and the stationary shroud.

Utility
Process of forming a metal additive manufactured part with a smooth surface
21 Sep 21
A process for forming a metal part from an additive manufacturing process with a smooth surface that includes the steps of printing the part using an AM process, heating the printed part to its solution heat treat or annealing temperature, placing the printed part in a fluidized salt bath for a short period of time to smooth a rough surface on the metal part, and then rapidly cool the heated metal part to prevent any change in grain structure.
