Multi-hole probes and methods for manufacturing multi-hole probes

摘要

A multi-hole probe has a kernel that includes a forward surface that includes at least a first, second, and third pressure sensing ports. The multi-hole probe kernel further includes an upper surface, generally orthogonal to the forward surface, and including at least a first, second, and third stem ports. Still further, the multi-hole probe kernel includes first, second, and third tubes running between and providing a fluid connection with the first, second, and third pressure sensing ports and the first, second, and third stem ports, respectively.

1. A multi-hole probe having a kernel comprising:
a forward surface comprising at least a first, second, and third pressure sensing ports, wherein the first pressure sensing port comprises a pitch angle of about −10° to about −45° and a yaw angle of about 0°, wherein the second pressure sensing port comprises a pitch angle of about 0° to about −10° and a yaw angle of about −35° to about −45°, wherein the third pressure sensing port comprises a pitch angle of about 0° to about −10° and a yaw angle of about +35° to about +45°, and wherein the first, second, and third pressure sensing ports are spaced apart from one another by a distance of greater than or equal to about 0.012 inches; an upper surface generally orthogonal to the forward surface and comprising at least a first, second, and third stem ports, wherein the first, second, and third stem ports are spaced apart from one another by a distance of greater than or equal to about 0.012 inches; and first, second, and third tubes running between and providing a fluid connection with the first, second, and third pressure sensing ports and the first, second, and third stem ports, respectively, wherein the first, second, and third tubes are contained fully within the kernel, wherein the first, second, and third tubes are each configured to redirect a gas flow pressure from a first direction to a second direction that is approximately orthogonal to the first direction, and wherein the kernel is sized at less than or equal to about 0.10 inches across in a third direction that is approximately orthogonal to both the first and second directions.
