Drag阻力
Drag is the aerodynamic force that resists an aircraft’s motion through the air, acting parallel and opposite to the flight path, and it is one of the four primary forces acting on an aircraft. In aerospace documentation, it appears in performance analysis, range and endurance calculations, flight test reports, and design trade studies where parasitic drag, induced drag, and total drag are quantified, often with reference to drag coefficient and drag polar.

Where this term appears
Drag appears in aircraft performance manuals, range and endurance calculations, mission planning tools, flight test reports, and aerodynamics training materials. Translators encounter 'drag coefficient,' 'induced drag,' 'parasite drag,' 'cooling drag,' and 'drag polar,' and must keep these categories distinct while avoiding the general sense of pulling or hauling.
Translation checks
A common error is translating drag as 'drag force' in an overly literal way or using 'pull' and 'towing resistance,' which are not standard in aerodynamic texts. Another is mistaking induced drag for parasite drag, which can produce contradictory statements in performance trade studies. The phrase 'drag polar' also needs explanation rather than word-for-word rendering.
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.
