Breaking sound barrier physics
WebJun 13, 2002 · We demonstrate the tunneling of audio pulses through the forbidden transmission zone of an acoustic band gap array. The acoustic band gap is created in a waveguide with a periodically spaced series of dangling sidebranches. Using an impulse response method, the transmission properties of the array are characterized and the … WebOnce you start going faster than sound, air flows over surfaces differently, and that causes catastrophic problems if you don't fix them. The first big challenge was maintaining lift on the wing. Air normally wants to flow sort of "attached" to the wing. It follows the curve and kind of "sticks" to it. This is called laminar flow.
