In some applications, aircraft air data probes are heated to prevent rain, ice, or other moisture from attaching to the air data probe. The body of the air data probe and the components positioned within the body of the air data probe can be constructed from differing materials, resulting in differing coefficient of thermal expansions for each component. Retention features are added to a housing to prevent an epoxy potting from expanding outside its intended region and preventing damage to the electronic components within the housing.

In some applications, aircraft air data probes are heated to prevent rain, ice, or other moisture from attaching to the air data probe, ensuring proper functionality of the air data probe. But the elevated temperatures can have negative effects on the electronic components positioned within the air data probe. Therefore, thermal isolating features are added to a housing to thermally isolate the heated parts of the air data probe from the electronic components within the air data probe, which are required to stay relatively cool for proper functioning.

A component having integral handling protection includes a main body, a fragile portion of the main body, and a removable portion of the main body positioned and configured to protect the fragile portion during handling of the component.

Additively manufactured integrated handling protection

A probe includes a housing defining a flow passage for a first fluid and having an entrance port and an exit port, a sensor configured to sense a parameter of the first fluid and positioned within the flow passage, and a hoop ejector connected externally to the housing such that a channel of the hoop ejector surrounds the exit port. The hoop ejector has a plurality of holes configured to port a second fluid from the channel such that the first fluid is aspirated from the flow passage and out through the exit port.
