    摘要： A system may include a controller configured to cause a capacitance probe to subject a material to a first electric signal having a first frequency and determine a first capacitance of the material at the first frequency. The controller is configured to cause the capacitance probe to subject the material to a second electric signal at a second frequency and determine a second capacitance of the material at the second frequency. The material includes at least a first constituent phase and a second constituent phase. The first constituent phase and the second constituent phase have substantially similar dielectric constants at the first frequency and substantially different dielectric constants at the second frequency. The controller is further configured to determine a porosity of the material based on the first capacitance and determine a relative phase composition of the first constituent phase and the second constituent phase based on the second capacitance.

    摘要： A system and a method for nondestructive testing of a component (12), e.g. a gas turbine engine blade, on a movable stage (26) in an inspection station (11) is disclosed. It includes providing a heat pulse to the exterior of the component (12), e.g. by flashing the component using a flash lamp (20) configured for flash thermography. It further includes collecting first image data regarding the component (12) using an infrared camera (14), flowing a fluid, e.g. cooling air, from a fluid supply (22) through the component (12), and collecting second image data regarding the component (12) using the infrared camera (14).

    摘要： A seal for use in a machine, such as a machine with rotating members, includes a labyrinth seal with multiple fins. The seal is slotted and is designed to limit fluid flow to the desired amount from the high pressure side of the seal to the low pressure side of the seal inside partially or exclusively radially extending cavities between two rotating members. The rotating members may operate at different speeds with a common axis of rotation. The seal remains effective when the rotating members move axially in relation to one another despite the fins having a component parallel to the axis of rotation.

    摘要： A gas turbine engine device is disclosed for mixing fuel and air prior to a combustion. The device includes a pilot mixer (60) and a main mixer (62) each having a fuel opening (88, 68) for the delivery of fuel to one or more passages. In one form the main mixer includes an inner passage (74) and an outer passage (76) and in which a fuel opening delivers fuel to the inner passage (74). The main mixer (62) can include swirlers in the inner and/or outer passages. The pilot mixer (60) can also include a swirler (66). In one embodiment the main mixer (62) includes a converging flow path and/or a diverging flow path. The pilot mixer (60) can also include a converging and/or diverging flow path and in one form is sheltered from an exit of the device. The main mixer fuel opening (88) can be disposed between an upstream end and a downstream end of the mixer.
