Abstract

Systems and methods for additive manufacturing for air data probes are provided. In at least one embodiment a probe comprises a support structure comprising one or more ports for receiving one or more fluids, the support structure comprising an endoskeleton mandrel having an opening for receiving a fluid; and a heating cable encircling an external surface of the endoskeleton mandrel. The probe also comprises an additive coating fused to the external surface of the endoskeleton mandrel and an external surface of the heating cable; and an internal assembly inside the support structure for carrying pressures from the one or more ports to one or more instruments that respond to the one or more fluids to provide a measurement.

First claim

The invention claimed is:

1. A probe, the probe comprising:
a support structure comprising one or more ports for receiving one or more fluids, the support structure comprising an endoskeleton mandrel having an opening for receiving a fluid;
a heating cable encircling an external surface of the endoskeleton mandrel;
an additive coating fused to the external surface of the endoskeleton mandrel and an external surface of the heating cable; and
an internal assembly inside the support structure for carrying pressures from the one or more ports to one or more instruments that respond to the one or more fluids to provide a measurement.

2. The probe of claim 1 , wherein the additive coating is added by at least one of:
a directed energy deposition process; and
a cold spray technology process.

3. The probe of claim 2 , wherein the additive coating added through the cold spray technology process is comprised of at least one of:
a metal;
a layer of one or more metals; and
a combination of one or more metals and one or more ceramics.

4. The probe of claim 1 , wherein the endoskeleton mandrel comprises one or more recessed portions on the external surface of the endoskeleton mandrel, wherein the heating cable encircles the endoskeleton mandrel within the one or more recessed portions and the additive coating is added to the endoskeleton mandrel within and/or over the recessed portions.

5. The probe of claim 4 , wherein the endoskeleton mandrel comprises a channel that extends from the external surface of the endoskeleton mandrel to the interior surface of the endoskeleton mandrel, wherein the channel allows fluid to pass from the external surface of the device to the interior surface of the endoskeleton mandrel.

6. The probe of claim 5 , wherein a channel ring extends around the external surface of the endoskeleton mandrel, wherein the channel ring separates a first recessed portion in the one or more recessed portions from a second recessed portion in the one or more recessed portions, wherein the heating cable passes from the first recessed portion to the second recessed portion through a groove in the channel ring.

7. The probe of claim 5 , wherein a channel pillar extends from the external surface of the endoskeleton mandrel around the channel, wherein the one or more recessed portions is comprised of a single contiguous recessed portion.

8. The probe of claim 1 , wherein the heating cable wraps around the endoskeleton mandrel through a groove that extends around an external surface of the endoskeleton mandrel.

9. An apparatus for providing air data sensing, the apparatus comprising:
a support structure comprising one or more ports for receiving one or more fluids, wherein the support structure comprises a tube having an inlet on a first end of the tube, wherein the inlet is a port in the one or more ports;
an attaching device for mounting the support structure to a vehicle;
a heating cable that extends from the attaching device through the support structure and wraps around the tube, wherein the heating cable is encapsulated within additive material that is fused to an external surface of the heating cable and a portion of an external surface of the support structure; and
an internal assembly inside the attaching device for carrying pressures of the one or more fluids to one or more instruments that respond to the one or more fluids to provide a measurement.

10. The apparatus of claim 9 , wherein the additive coating is added by at least one of:
a directed energy deposition process; and
a cold spray technology process.

11. The apparatus of claim 9 , wherein the endoskeleton mandrel comprises one or more recessed portions on the external surface of the endoskeleton mandrel, wherein the heating cable encircles the endoskeleton mandrel within the one or more recessed portions and the additive coating is fused to the endoskeleton mandrel within and/or over the one or more recessed portions.
