As a toy for a supervillain: Sure you have cruise missiles that hug the ground and avoids radar but what kind of style is that. Bring back the buzz jet engine, use a fuel injector and control it with pulse width modulation so that it plays an appropriate tune as it crosses the country side.
Every
supervillain could have their own theme song.

Why not an array of nozzles?

How can you not give this a bun. |

Hey - an application for my invention already. |

How would you adjust the tune so that it would not be spoiled by the Doppler effect? |
|

The Doppler Effect would only compress or expand the scale and frankly supervillains don’t bloody care about perfect pitch. Indeed being off fits the persona. So does misspelling stuff. Baaaa Haaaaa Haaaaa |

Cool idea, and it would be nice, but it won't work as described. A buzz jet is tuned to the length of the tailpipe. It plays one steady note, and there isn't anything that you can do about that with a fuel injector. Just maybe, if you made a sliding tailpipe, you could make a trombone effect, maybe. |

Compressor up front, rotating perforated disk that opens and closes a port at 40 kilohertz, small chamber after that with fuel injector, second perforated disk, combustion chamber with spark plug, tube designed to silence frequencies above 20 kilohertz. Theory of operation: At 40 kilohertz air enters the first chamber and is mixed with varying amounts of fuel, this is then pushed into the combustion chamber by the next charge where it is ignited. The varying amounts of fuel create varying amplitude impulses that are combined by the low pass effect of the tube. The trick is to create compression and insure ignition only by spark. This is not a standard pulse jet design but there are variations. And you don’t have to have a tuned pipe to get air into the combustion chamber. The first designs used “ram air”, A catapult was used to get the jet up to speed and a funnel shape compressed air into the combustion chamber. The tuned pipe just allows the jet to work at low speeds. Blow this design out a tube like a mortar, let the wings extend and away she goes playing her tune. |
