ABOUT THIS PROJECT


Tell us briefly about your project. Is it a work of art or does it serve another function?

The large ornate birdcage holds five spinning pulse jet engines of various sizes that create a range of percussive and droning tones. The pulse jets are mounted at various heights within the cage and spin around on their own thrust, sometimes very fast! Through a completely interactive console interface, the public can create sound compositions by controlling the amount of fuel and spark going to each individual jet. The console has the look of something old world a la Jules Verne, with funky mechanical switches and gears adding to the playfulness of the sculpture. The public can enjoy playing these jet engines in an explosive cacophonous symphony while watching them spin around and expel fire. Caged Pulse Jets is a highly entertaining sound sculpture that is fun to play and watch for kids and adults alike..

When did you start working on this project and how long did it take you to complete?

I first started building it in 2010. It has been through four revisions since, and runs better now than ever. I work on it every time I show it as I have new ideas that I incorporate into the sculpture, but as a whole it is done.

What was your goal in building this project?

For the audience to get to interact with a fiery sound sculpture and learn about pulse jet engines.

Does your project help to solve a problem? If so what problem?

It may fall into a learning experience as the audience, once interfacing with the jets, are experiencing the sheer force of a pulse jet as well as making some controlled sounds together.

What makes your idea unique?

I dreamt it, and I have not seen anything like it before.

In what capacity are you using bearings and what type of bearings?

I use roller bearings on all the commutators. The two port commutators are spinning at very high speeds, from the thrust of the jet and carry the weight of the jet arm and its components.

What is the most important thing you want people to know about your project?

That it is interactive and to get up close with these really amazing pulse jets to make some noise.

How will you use the $5,000 prize?

To fund further sculpture projects, of course!
