A method and apparatus for covering an end of a housing for an engine. In one embodiment, an apparatus comprises a structure, a flange, and a retaining feature. The structure is configured to cover an opening of a housing for an engine. The flange is comprised of a deformable material and is configured to extend from the structure around a circumference of the structure. The retaining feature is configured to extend from a middle portion of the structure such that the retaining feature and the flange form a channel configured to receive an end of the housing. The retaining feature is configured to extend into an inlet of the engine through the opening of the housing to form an interference fit with a portion of an interior surface of the housing.

1. An apparatus comprising: a structure configured to cover an opening of a housing for an engine;a static flange comprised of a deformable material and configured to extend from the structure around a circumference of the structure; anda retaining feature configured to: extend, substantially 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. 2. The apparatus of claim 1, wherein the flange has a thickness selected to absorb at least a portion of kinetic energy applied to the flange to reduce a possibility of a number of inconsistencies forming at the end of the housing in response to the kinetic energy being applied to the flange. 3. The apparatus of claim 1, wherein the structure has a shape selected to fully cover the opening of the housing for the engine. 4. The apparatus of claim 1, wherein an exterior surface of the housing does not contact an inner surface of the flange and an edge of a cowl structure of the housing does not contact a base of the channel when the interference fit is formed. 5. The apparatus of claim 1, wherein the flange comprises: an inner surface in which the inner surface of the flange forms a portion of the channel; andan outer surface. 6. The apparatus of claim 1, wherein the flange is configured to extend over a portion of an exterior surface of the housing when the interference fit is formed. 7. The apparatus of claim 1 further comprising: a number of handles attached to an exterior side of the structure. 8. The apparatus of claim 1, wherein the deformable material is a foam material. 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. The apparatus of claim 1, wherein the engine is a jet engine for an aircraft. 11. The apparatus of claim 1, wherein the structure comprises: an interior side in which the flange and the retaining feature are configured to extend from the structure at the interior side of the structure; andan exterior side. 12. The apparatus of claim 11, wherein the exterior side of the structure is substantially planar. 13. The apparatus of claim 1, wherein the retaining feature comprises: an outer surface, wherein the outer surface forms a portion of the channel; andan inner surface. 14. The apparatus of claim 13, wherein the inner surface of the retaining feature forms a hollow portion in the retaining feature. 15. The apparatus of claim 13, wherein the retaining feature further comprises: an outer layer of material on the outer surface of the retaining feature, wherein the outer layer of material comprises another deformable material. 16. 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, such that the cover comprises: a structure; a static flange comprised of a deformable material extending from the structure around a circumference of the structure; and a retaining feature extending substantially as a hollowed cylinder, from a middle portion of the structure, the structure sealing an end of the hollowed cylinder, the retaining feature and the flange forming a channel;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;forming an interference fit between the retaining feature and a portion of an interior surface of the housing; andreceiving the end of the housing into the channel. 17. The method of claim 16, wherein the step of positioning the cover relative to the end of the housing for the engine comprises: positioning the cover relative to the end of the housing for the engine such that an interior side of the structure faces the end of the housing. 18. The method of claim 16, wherein the step of moving the cover in the direction towards the end of the housing for the engine such that the retaining feature extends into the inlet of the engine through the opening of the housing to form the interference fit between the retaining feature and the portion of the interior surface of the housing comprises: moving the cover in the direction towards the end of the housing such that the retaining feature extends into the inlet of the engine through the opening of the housing; andpushing the cover in the direction towards the end of the housing such that an outer surface of the retaining feature pushes against the interior surface of the housing to form the interference fit with the portion of the interior surface of the housing. 19. The method of claim 18, wherein the step of pushing the cover in the direction towards the end of the housing such that the outer surface of the retaining feature pushes against the interior surface of the housing to form the interference fit with the portion of the interior surface of the housing comprises: pushing the cover in the direction towards the end of the housing such that the outer surface of the retaining feature pushes against the interior surface of the housing to form the interference fit with a desired level of stiction between the outer surface of the retaining feature and the portion of the interior surface of the housing. 20. A cover for an inlet of a jet engine, the cover comprising: a structure configured to cover an opening into the inlet of the jet engine in which the opening is defined by a leading edge of a cowl structure for the jet engine, wherein the structure has an interior side and an exterior side in which the exterior side is substantially planar;a static flange comprised of a deformable material and configured to extend from the structure around a circumference of the structure at the interior side of the structure; anda retaining feature configured to: extend, substantially as a hollowed cylinder into the inlet through the opening, from a middle portion of the structure at the interior side 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 the leading edge of the cowl structure for the jet engine; and form an interference fit with a portion of an interior surface of the cowl structure for the jet engine.
