Abstract
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.
Claims19
An air data probe comprising:
- a body comprising an inlet fluidly coupled to an outlet;
- a heating element positioned within the body of the air data probe, wherein the heating element is configured to increase a temperature of the body;
- a sensing probe positioned within the body, wherein the sensing probe includes a sensing base coupling the sensing probe to the body;
- and
- a housing positioned within and coupled to the body, wherein the housing includes:
- a housing body including an upper surface, a lower surface, an inner surface, and an outer surface;
- and
- a plurality of retention features positioned within the housing body, wherein each of the plurality of retention features extend from the inner surface of the housing towards a central axis of the housing.
A housing for surrounding electrical components within an air data probe configured to gather data during flight of an aircraft, the housing comprising:
- a housing body including an upper surface, a lower surface, an inner surface, an outer surface, a rim positioned adjacent the upper surface, and a lower body positioned adjacent the lower surface;
- a plurality of retention features positioned within the housing body, wherein each of the plurality of retention features extend from the inner surface of the housing towards a central axis of the housing;
- and
- a first alignment feature and a second alignment feature, wherein the first alignment feature is positioned adjacent the rim of the housing body, and wherein the second alignment feature is positioned adjacent the lower body of the housing body.
