Meaning and Definition
A type of jet engine (like a pulsejet) that operates by creating pressure waves that resonate in a specially shaped combustion chamber, producing intermittent thrust.
A reactive propulsion device where combustion occurs in pulses, synchronized with acoustic resonances in its ducting, making it mechanically simpler than continuous-flow jet engines but less efficient. Historically used in propulsion systems like the V-1 flying bomb.
Dialectal Variation
British vs American Usage
Differences
No significant usage difference. The term is technical jargon. Spelling follows standard national conventions for the component words.
Connotations
Connotes mid-20th century aerospace technology, historical military applications, and a specific, somewhat obsolete engineering solution.
Frequency
Extremely low frequency in both variants, limited to historical aeronautical texts and specialized engineering discourse.

FAQ
Frequently Asked Questions
Essentially, yes. 'Resonant-jet engine' is a descriptive term often used for pulsejets, especially those where the design explicitly utilizes acoustic resonance in a tuned tube.
They are very inefficient at most speeds, extremely noisy, and produce high levels of vibration compared to turbojets and turbofans, making them unsuitable for commercial or most military aviation.
The German V-1 flying bomb (or 'doodlebug') of World War II used an Argus As 014 pulsejet, a type of resonant-jet engine.
Unlike a turbojet, a basic resonant-jet engine cannot produce static thrust; it requires forward motion to initiate efficient air intake and resonance, though some designs with forced air induction can start from a standstill.
A type of jet engine (like a pulsejet) that operates by creating pressure waves that resonate in a specially shaped combustion chamber, producing intermittent thrust.
Resonant-jet engine is usually technical / historical engineering in register.
Resonant-jet engine: in British English it is pronounced /ˈrɛzənənt ˌdʒɛt ˈɛnʤɪn/, and in American English it is pronounced /ˈrɛzənənt ˌdʒɛt ˈɛnʤən/. Tap the audio buttons above to hear it.

Mnemonic
Imagine an engine that 'sings' or 'humms' loudly (resonates) to create jet thrust.
Conceptual Metaphor
AN ENGINE IS A MUSICAL INSTRUMENT (it uses tuned resonance to operate).
