Abstract: A system for forming a nozzle inlet of a nozzle includes a nozzle body and an electro-chemical machining (ECM) assembly. The nozzle body includes an external surface. The nozzle body forms a nozzle orifice and a manifold passage. The nozzle orifice extends through the nozzle body between and to a nozzle inlet and a nozzle outlet. The nozzle inlet is disposed at the manifold passage. The nozzle outlet is disposed at the external surface. The ECM assembly is installed on the nozzle body. The ECM assembly includes a machining tool and a flexible line. The machining tool is disposed at the nozzle inlet. The flexible line is attached to the machining tool. The flexible line extends through the nozzle outlet from the machining tool to an exterior of the nozzle body.

Abstract: A fluid supply system and method is provided that includes a fluid pump, a pressure sensor, a pressure relief valve (PRV), and a fluid monitoring device. The fluid pump receives fluid from a first conduit and discharges fluid into a second conduit. The pressure sensor produces sensed fluid pressure signals. The PRV is in signal communication with the pressure sensor. The fluid monitoring device includes a control orifice in fluid communication with second and third conduits. The second conduit has a first inner diameter, the third conduit has a second inner diameter, and the control orifice has an orifice inner diameter, and the orifice inner diameter is less than the first and second inner diameters. The pressure sensor senses fluid pressure in the third conduit at a position in close proximity to the control orifice. The fluid monitoring device may be in a lead or a lag domain configuration.

Abstract: An assembly for a gas turbine engine includes at least one burner and a hydrogen manifold. The at least one burner includes an outer nozzle and an inner nozzle. The outer nozzle forms a combustion chamber. The outer nozzle includes an outer converging axial portion and an outer diverging axial portion. The outer converging axial portion is disposed at an upstream axial end of the outer nozzle. The outer diverging axial portion is disposed axially downstream of the outer converging axial portion. The inner nozzle includes an inner converging axial portion at a downstream axial end of the inner nozzle. The inner converging axial portion is disposed within the outer converging axial portion to form an annular gap between the outer converging axial portion and the inner converging axial portion. The hydrogen manifold is disposed at the upstream axial end. The hydrogen manifold is connected in fluid communication with the annular gap.
