An aircraft powered by three engines.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque "трехмотор" as it is not a standard term. Use "самолет с тремя двигателями" or the borrowed "тримотор" only in historical context.
Common Mistakes
- Spelling as 'tri-motor' or 'tri motor' (while common, the closed form 'trimotor' is standard for the aircraft).
- Using it to describe any old plane, rather than specifically a three-engine one.
- Pronouncing the 'tri' as /trɪ/ instead of /traɪ/.

FAQ
Frequently Asked Questions
No, it is a low-frequency technical/historical term. Most people will only encounter it in specific contexts related to aviation history.
Technically, yes—it describes the configuration. However, in practice, the term is so strongly associated with the Ford aircraft of the 1920s-30s that it often refers specifically to them.
For its era, it was considered very safe and advanced. Its three engines meant it could potentially maintain altitude with one engine failed, a major selling point at the time.
Modern three-engine passenger jets (like the Boeing 727, Lockheed L-1011) exist but are almost never called 'trimotors'. The term is firmly rooted in the propeller-driven era.
