Nacelle发动机舱
A nacelle is the streamlined housing or enclosure that surrounds an aircraft engine, and may also refer to similar enclosures for other external equipment. In technical publications, the term appears in airframe and powerplant descriptions, structural repair manuals, and component maintenance publications to identify access panels, cowling assemblies, mounting structure, and surrounding skin panels that require routine inspection and repair.

Where this term appears
Translators encounter nacelle in aircraft maintenance manuals, engine build-up documents, illustrated parts catalogs, structural repair instructions, and service bulletins. It appears in descriptions of cowl removal, thrust reverser access, anti-ice systems, and composite panel repairs. Localization must preserve the distinction between nacelle, cowling, and engine casing based on the surrounding maintenance context.
Translation checks
A frequent error is translating nacelle as "发动机舱" in a way that conflicts with "engine bay" or using "吊舱" indiscriminately for podded equipment. On some aircraft, nacelle refers to a specific structural assembly with its own part numbers and repair limits, so inconsistent terminology can cause confusion when ordering parts or following structural repair manual tasks.
