Please note this model is for a single engine for you to create your own sonic resonance vehicle with. If you would like to make the whole vehicle click here. Check out sonicramjet.com to learn more about how it works!I created an engine with no moving parts that generates enough thrust to move a small model craft. The engine is not ported, everything coming our of the jet are sound waves. This model is just the resonance chamber, aka "the engine". It works by feeding a 40hz signal through amplification, then resonating it 3x to compress the sound waves into a uniform, stacking jet. I was inspired by sonic booms, and annoying deep-bass from passing cars that rattles the whole house. The vibration of the chamber also helps greatly reduce the coefficient of friction. I borrowed that trick from water striders.To make this work you need a 1.5"(39mm) speaker, an amp, and a way to provide a 40hz signal. A sine wave generator is by far the cheapest and best option for performance.
