Integral instrumentation in additively manufactured components of gas turbine engines

A pressure probe includes a non-deflecting airfoil, a sensing feature, and an interior passage. The non-deflecting airfoil is made of a metal and configured for use in a gas turbine engine. The airfoil extends from a base to a tapered portion, and then to a linear portion, along a primary axis. The...

Beschreibung
Zusammenfassung:	A pressure probe includes a non-deflecting airfoil, a sensing feature, and an interior passage. The non-deflecting airfoil is made of a metal and configured for use in a gas turbine engine. The airfoil extends from a base to a tapered portion, and then to a linear portion, along a primary axis. The sensing feature is formed monolithically with the airfoil, as by additive manufacturing. The interior passage is operatively connected to the sensing feature and passes through both the airfoil and the base.
