Meaning and Definition
A type of pulse jet engine that uses a resonant chamber to produce thrust via intermittent combustion pulses.
A simple, valveless propulsion system commonly used in model aircraft and target drones, characterised by its characteristic buzzing sound and operation through acoustic resonance.
Dialectal Variation
British vs American Usage
Differences
Usage is identical in technical contexts. The spelling 'engine' is standard in both. 'Resojet' may sometimes be hyphenated as 'reso-jet' in older texts.
Connotations
Technical precision, simplicity of design, historical aerospace technology, hobbyist projects.
Frequency
Extremely rare in general language. Used with equal, specialised frequency in UK and US engineering/aeromodelling circles.

- Confusing it with a 'ramjet' or 'turbojet', which are fundamentally different.
- Using it as a general term for any jet engine.
FAQ
Frequently Asked Questions
No. Passenger planes use turbofan engines. A resojet is a much simpler, older type of pulsejet used for small-scale applications like drones or models.
The buzzing sound is caused by the rapid, periodic combustion pulses (often 40-250 per second) inside the resonant chamber, which operates like an acoustic organ pipe.
No, most simple designs require forward motion to ram air into the intake for starting and efficient operation, unlike a rocket engine.
Almost exclusively in the hobbyist sector for powering model aircraft, or historically in some early guided missiles like the German V-1 (which used a similar, but valved, pulsejet).
A type of pulse jet engine that uses a resonant chamber to produce thrust via intermittent combustion pulses.
Resojet engine is usually technical/engineering/aerospace in register.
Resojet engine: in British English it is pronounced /ˈrɛz.əʊ.dʒɛt ˈɛn.dʒɪn/, and in American English it is pronounced /ˈrɛz.oʊ.dʒɛt ˈɛn.dʒən/. Tap the audio buttons above to hear it.

Mnemonic
Think: RESOnant JET – the engine works by creating a resonant buzzing JET of air.
Conceptual Metaphor
AN ENGINE IS A MUSICAL INSTRUMENT (it operates on acoustic resonance principles).
