Engine cowl and inlet cover

摘要

A method for covering an end of a housing for an engine. A cover is positioned relative to the end of the housing for the engine. 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. The cover is moved 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.
