Engine cowl and inlet cover

1. An apparatus comprising:

a structure configured to cover an opening of a housing for an engine;

a flange comprised of a deformable material and extending from the structure around a circumference of the structure;

a retaining feature configured to extend as a hollowed cylinder into an inlet of the engine through the opening of the housing from a middle portion of the structure, the hollowed cylinder being sealed at one end by the structure, such that the retaining feature and the flange form a channel configured to receive an end of the housing and form an interference fit with a portion of an interior surface of the housing;

a sealing system configured to reduce moisture entering the opening of the housing into the inlet of the engine; and

wherein the sealing system comprises a group of sealing members.

2. The apparatus of claim 1 , wherein the group of sealing members includes at least one of an o-ring, a bulb seal, an adhesive strip, or a sealant.

3. The apparatus of claim 1 further comprising:

a compression system configured to compress the group of sealing members against the housing.

4. The apparatus of claim 1 further comprising:

a holding structure configured to hold a desiccant within a hollow portion of the retaining feature, wherein an inner surface of the retaining feature forms the hollow portion in the retaining feature.

5. The apparatus of claim 1 further comprising:

an inspection window located in the structure, wherein the inspection window provides a view of a hollow portion of the retaining feature.

6. The apparatus of claim 1 , wherein an inner surface of the flange and an outer surface of the retaining feature form the channel without contacting the inlet of the engine.

7. The apparatus of claim 1 , wherein the structure has a shape selected to fully cover the opening of the housing for the engine.

8. The apparatus of claim 1 further comprising:

a number of handles attached to an exterior side of the structure.

9. The apparatus of claim 1 , wherein the deformable material is selected from one of a foam material, a polyurethane material, an elastomer, a polymer, a shape memory polymer, a syntactic foam material, an integral skin foam material, and an aerogel.

10. A method for covering an end of a housing for an engine, the method comprising:

positioning a cover relative to the end of the housing for the engine, wherein the cover comprises a structure, a flange comprised of a deformable material extending from the structure around a circumference of the structure, and a retaining feature configured to extend from a middle portion of the structure such that the retaining feature and the flange form a channel configured to receive the end of the housing;

moving the cover in a direction towards the end of the housing for the engine such that the retaining feature extends into an inlet of the engine through an opening of the housing to form an interference fit between the retaining feature and a portion of an interior surface of the housing; and

compressing a sealing system against the housing with a compression system configured to compress a group of sealing members.

11. The method of claim 10 further comprising:

placing a desiccant on a holding structure within a hollow portion of the retaining feature, wherein an inner surface of the retaining feature forms the hollow portion in the retaining feature.

12. The method of claim 11 further comprising:

inspecting a status of the desiccant through an inspection window located in the structure, wherein the inspection window provides a view of the desiccant on the holding structure.

13. The method of claim 10 , wherein an inner surface of the flange and an outer surface of the retaining feature form the channel without contacting the inlet of the engine.

14. The method of claim 10 , wherein the structure has a shape selected to fully cover the opening of the housing for the engine.

15. The method of claim 10 , wherein a number of handles is attached to an exterior side of the structure.

16. The method of claim 10 , wherein the deformable material is selected from at least one of a foam material, a polyurethane material, an elastomer, a polymer, a shape memory polymer, a syntactic foam material, an integral skin foam material, or an aerogel.

17. The method of claim 10 , wherein the sealing system comprises:

the group of sealing members.

18. The method of claim 17 , wherein the group of sealing members includes at least one of an o-ring, a bulb seal, an adhesive strip, or a sealant.
