The cage containing the jets stands 17' tall, including the top lifting ring, and is 18' wide at its widest. The jet cage has an octagonal footprint and is decorated ornately with forged elements to look like a giant bird cage. Inside, hidden within the structure, run propane, air and electric- the three ingredients for the valveless pulse jet engines to work. Five arms run out from the cage structure and hold the pulse jets and their fuel. Each jet has its own axis that it will spin freely around powered by its engine thrust. This will also add a stereo sound component to each jet.
I am hoping to get frequencies ranging from 60 Hertz to 600 Hertz, and that will depend on the actual size of the jet. There is a user interface control panel outside of the cage that enables the public to "play" the jets as they will have the ability to modify the amount of fuel, and air. I would like it to be a control panel that can be played by one or several people-a moon shaped panel with sets of three buttons/knobs/switches for each jet. The control panel is attached and tethered to the cage. The incredible sounds that these jets can make will create a thunderous symphony like no other. While running, the jets will radiate their bright orange and yellow glow, resembling dynamic and awe-inspiring birds flying around in their bird cage.
