Abstract

A cover for a probe head of an air data probe includes a sleeve defining a cavity for enclosing a portion of the probe head of the air data probe, the sleeve including a closed end, an open end opposite the closed end, and an interior surface extending from the open end to the closed end, and a reservoir for holding insect repellent, the reservoir located at least partially within the cavity of the sleeve.

First claim

The invention claimed is:

1. A method for repelling insects from an opening of an air data probe, the method comprising:
placing a cover on a probe head of the air data probe, the cover including:
a reservoir for holding insect repellent; and
a sleeve defining a cavity for enclosing a portion of the probe head of the air data probe to prevent insects from entering the opening of the probe head when the cover is on the probe head, the sleeve including:
a closed end;
an open end opposite the closed end;
an interior surface extending from the open end to the closed end;
a cylindrical portion extending from the open end; and
a tapered portion connected to the cylindrical portion and defining the closed end;

forming a sealing engagement between the interior surface of the cylindrical portion of the sleeve of the cover and an exterior surface of the probe head adjacent the open end of the sleeve when the cover is on the probe head;
dispersing the insect repellent from the reservoir onto the probe head, wherein the reservoir is located at least partially within the cavity of the sleeve and within the tapered portion between the interior surface of the sleeve and an exterior surface of the probe head such that an open space remains within the cavity, the open space being between the interior surface of the sleeve and the exterior surface of the probe head, between the closed end of the sleeve and the sealing engagement, and adjacent the reservoir, when the cover is on the probe head; and
removing the cover from the probe head;
wherein the reservoir is positioned to disperse the insect repellent on the probe head adjacent the opening of the probe head so that the insect repellant is dispersed within the open space to produce a residual effect to deter insects from entering the opening of the probe head after the cover is removed from the probe head.

2. The method of claim 1 , wherein the reservoir is a sponge located within a sleeve of the cover.

3. The method of claim 1 , wherein the reservoir is a porous liner located within a sleeve of the cover.

4. The method of claim 1 , wherein the reservoir is a bottle connected to the cover.

5. The method of claim 1 , wherein the reservoir is electrically-actuated.

6. The method of claim 1 , wherein the reservoir is spring-actuated.

7. The method of claim 1 , wherein the insect repellent is a fluid.

8. The method of claim 1 , wherein the insect repellent is a gel.

9. The method of claim 1 , wherein the opening of the air data probe is configured to take in air from surrounding airflow to communicate air pressures pneumatically through internal components and passages of the probe head and a strut of the air data probe to generate air data parameters.

10. The method of claim 1 , further comprising preventing insects from entering the opening of the probe head when the cover is on the probe head.
