Bulkhead隔框
A bulkhead is a structural partition or load-bearing wall inside an airframe, typically located at major fuselage stations, that separates compartments, carries pressure loads, or supports attached equipment and systems. In technical documentation, it appears in structural repair manuals, illustrated parts catalogs, airframe descriptions, and modification or weight-and-balance records where station numbers and structural boundaries are defined and used for damage mapping.

Where this term appears
This term appears in structural repair manuals, damage assessment reports, illustrated parts catalogs, maintenance task cards, and airframe modification documents. When localizing MRO or OEM materials, translators must retain the distinction between a pressure bulkhead, a frame-like bulkhead, and firewall partitions, and keep station-number references consistent with engineering drawings and damage location zones.
Translation checks
A common mistake is translating bulkhead generically as 'wall' or 'partition panel,' which can hide its load-bearing or pressure-retaining role. In structural repair documents, this can lead to incorrect damage limits or repair categories. Another error is confusing it with frame, longeron, or intercostal, terms that occupy different positions in airframe structure and must remain distinct.
Keep the term aligned across your files
Check procedure sequence, part names, limits and cautions against the supplied references. Applicable aviation or market requirements depend on the product and project pathway.
Provide approved terms and previous translations with the source files. Agree how variants, ambiguous wording and revisions will be reviewed. Terminology maintenance and any termbase handback are confirmed in the project scope. See the 8-step AI + expert workflow.
