Abstract: A system can include a torsion applicator (e.g., a torsion motor and shaft) configured to apply a torque to a test article that is additively built on and attached to a build plate. The system can include at least one twist sensor and at least one torque sensor. A method for determining quality of an additively manufactured article or batch thereof can include torsion testing at least one additively manufactured test article that is built on and attached to a build plate while the at least one test article is still attached to the build plate.

Abstract: A dynamic seal assembly is disclosed for use in a valve having an upstream pressure side and a downstream pressure side, the dynamic seal assembly including an annular seal member having a generally C-shaped cross-section and including opposed upstream and downstream legs defining an internal cavity with an opening facing toward the upstream pressure side of the valve, wherein the upstream leg has a radial length that is greater than a radial length of the downstream leg and includes a retaining foot that extends angularly away from the upstream leg in an upstream direction at an angle of between about 0° and 90°, and a metallic spring is disposed within the internal cavity of the seal member for providing a constant sealing force to the seal member.

Abstract: A fluid nozzle includes, a body having an annular cavity that extends out one axial end of the fluid nozzle. At least one port fluidically connects to an annular chamber of the annular cavity and the annular cavity is defined between a radially inner surface of the body and a radially outer surface of the body. A first portion of the radially outer surface has a first radial dimension smaller than a greatest radial dimension of the at least one port and a second portion of the radially outer surface further from the annular chamber than the first portion has a second radial dimension greater than the first radial dimension and so forth.

Abstract: In accordance with at least one aspect of this disclosure, a fuel injector can include an annular body defining a gas fuel inlet therein, and a structure extending radially outward from the annular body and configured to extend into an air circuit. The structure can include a gas channel defined within the structure at least partially along a radial length of the structure. The gas channel is in fluid communication with the gas fuel inlet where the structure meets the annular body. The structure also includes a slot opening defined at least partially along a radial length of the structure and configured to fluidically connect the gas channel and the air circuit to all gas fuel to effuse into the air circuit.

Abstract: An injector includes a housing including a fluid passage extending from an inlet of the housing to an outlet end of the housing. An actuator is mounted within the housing. A pintle extends along a longitudinal axis from an actuator end to a pintle head. The actuator end of the pintle is operatively connected to the actuator for actuation along the longitudinal axis. A tip member is mounted to the outlet end of the housing. The tip member includes an outlet orifice and a pintle seat. In a seated position of the pintle, the pintle head blocks flow to the outlet orifice. In an open position of the pintle, the pintle head allows flow. The pintle head includes a swirl passage therein, wherein the swirl passage is angled tangential relative to the longitudinal axis to induce swirl on flow passing between the pintle head and the pintle seat.
