elevon
C2 / Very Low FrequencyTechnical / Specialized
Definition
Meaning
A hinged control surface on the trailing edge of an aircraft wing, combining the functions of an elevator and an aileron.
A single control surface used primarily on tailless aircraft (like delta-wing fighters or flying wings) to control both pitch (nose up/down) and roll (banking).
Linguistics
Semantic Notes
The term is a portmanteau of 'elevator' and 'aileron'. It is exclusively used in aviation, aerospace engineering, and aeromodelling contexts. Not used metaphorically.
Dialectal Variation
British vs American Usage
Differences
No semantic or usage differences. The term is identical in both dialects within technical contexts.
Connotations
Technical precision, advanced aircraft design.
Frequency
Extremely low frequency in general language but standard within its technical domain in both regions.

Examples
By Part of Speech
adjective
British English
- The elevon mechanism was inspected.
- elevon control logic
American English
- The elevon actuator failed.
- elevon hinge point
Examples
By CEFR Level
- The drone's flight controller adjusts the elevons automatically.
- On a flying wing, the elevons are the primary control surfaces.
- Differential movement of the elevons induces roll, while symmetric movement controls pitch.
- The engineer analysed the elevon's hinge moment to size the hydraulic actuators correctly.
Learning
Memory Aids
Mnemonic
Think: ELEVator + ailerON = ELEVON. It lifts (elevates) one wing and lowers the other for combined pitch and roll control.
Conceptual Metaphor
Not applicable; the term is purely technical and literal.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'лифт' (elevator/lift).
- The Russian equivalent is 'элевон'. It is a direct loanword with identical meaning.
Common Mistakes
- Misspelling as 'elevatoron' or 'aileronator'.
- Using it to refer to any generic wing flap.

FAQ
Frequently Asked Questions
No, it is a highly specialized technical term used almost exclusively in aviation and aerospace contexts.
No, it is solely a noun. The related action would be 'to deflect the elevons' or 'to control via elevons'.
They are standard on tailless aircraft designs such as delta-wing fighters (e.g., Eurofighter Typhoon), flying wings (e.g., B-2 Spirit bomber), and many unmanned aerial vehicles (UAVs) and model aircraft.
An elevon combines elevator and aileron functions. A flaperon combines flap (for lift) and aileron functions. Some aircraft may use both types of surfaces.
