swing-wing
C1/C2 (low-frequency technical term)Technical/aviation
Definition
Meaning
An aircraft wing that can be swept back and adjusted during flight.
A variable-geometry wing design used on certain military aircraft to optimise performance at both low and high speeds.
Linguistics
Semantic Notes
Primarily a noun, used attributively (as in 'swing-wing aircraft'). The hyphen is standard. Refers specifically to the mechanical wing design, not to the act of swinging wings.
Dialectal Variation
British vs American Usage
Differences
No significant lexical difference. The term is equally technical in both varieties.
Connotations
Strongly associated with Cold War-era military aviation technology (e.g., Panavia Tornado, F-14 Tomcat, MiG-23).
Frequency
Very low frequency in general discourse. Almost exclusively used in historical, technical, or enthusiast contexts related to aerospace engineering.

Examples
By CEFR Level
- Some fighter jets have special wings called swing-wings.
- The swing-wing can move during flight.
- The main advantage of a swing-wing design is that it allows for efficient flight at both low and high speeds.
- Developing reliable swing-wing mechanisms was a major technical achievement in the 1960s.
- While swing-wing aircraft offered unparalleled versatility, their mechanical complexity and weight made them exceedingly costly to maintain.
- The strategic bomber utilised a swing-wing configuration to penetrate enemy defences at high speed and then loiter at lower speeds.
Learning
Memory Aids
Mnemonic
Imagine a plane SWINGing its WINGs back like arms to go faster.
Conceptual Metaphor
ADAPTABILITY IS PHYSICAL MOVEMENT (The wing's physical swing enables adaptation to different flight conditions).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'качающееся крыло'. The correct Russian technical term is 'крыло изменяемой стреловидности' (KISO) or simply 'изменяемая геометрия крыла'.
Common Mistakes
- Using 'swing wing' without a hyphen (should be hyphenated).
- Using it as a verb (e.g., 'The plane can swing-wing').

FAQ
Frequently Asked Questions
It is a hyphenated compound noun: 'swing-wing'.
No. Modern fighter design, aided by computers and advanced materials like composites, has moved away from complex mechanical swing-wings in favour of fixed wings optimized for specific flight regimes or using other means like thrust vectoring.
They are synonyms. 'Swing-wing' is the common name, while 'variable-geometry wing' or 'variable-sweep wing' is the more formal, technical term.
No. 'Swing-wing' is exclusively a noun (or noun used attributively as an adjective). You cannot say 'The plane swing-wings'. You would say 'The plane sweeps its wings back' or 'The wing swings back'.
