Abstract

A method of making an air data probe may comprise forming a probe body, forming an interior cavity into the probe body, applying a protective shell to the probe body by an additive manufacturing technique, inserting a heating element into the interior cavity, machining a final profile of the air data probe, and forming a sensing port comprising a port passage defined through the probe body and lined by a portion of the protective shell.

First claim

The invention claimed is:

1. A method of making an air data probe comprising:
forming a probe body;
forming an interior cavity into the probe body;
applying a protective shell to the probe body by an additive manufacturing technique;
inserting a heating element into the interior cavity;
machining a final profile of the air data probe; and
forming a sensing port comprising a port passage defined through the probe body and lined by a portion of the protective shell.

2. The method according to claim 1 , wherein forming the sensing port further comprises:
forming a sensing port recess comprising an indentation formed in the probe body; and
applying the portion of the protective shell disposed over the sensing port recess and forming a substantially continuous surface over the indentation,
wherein the port passage comprises an aperture defined by the portion of the protective shell and in fluidic communication with an environment and the interior cavity.

3. The method according to claim 2 , wherein the port passage is aligned coincident with a geometric center of the sensing port recess.
