	A triggered [[burst disk]] system ~~consists~~ of two burst disks mounted between the [[chamber]] and [[barrel]] of a [[pneumatic cannon]], with a trigger chamber in between and a trigger [[valve]] that either dumps said chamber to the atmosphere, or connects it to the main chamber.		A triggered [[burst disk]] system allows the user to accurately control the time of firing, in one of two ways:

			_Cascade Failure_
			Cascade failure systems consist of two burst disks mounted between the [[chamber]] and [[barrel]] of a [[pneumatic cannon]], with a trigger chamber in between and a trigger [[valve]] that either dumps said chamber to the atmosphere, or connects it to the main chamber.

	The burst disks must be dimensioned to break somewhere between half and full chamber [[pressure]]. The trigger chamber is filled to half the chamber pressure, and then the chamber is filled to full pressure. When the trigger valve is opened, one of the disks is subjected to the full chamber pressure and ruptures, in turn overloading and rupturing the second burst disk.		The burst disks must be dimensioned to break somewhere between half and full chamber [[pressure]]. The trigger chamber is filled to half the chamber pressure, and then the chamber is filled to full pressure. When the trigger valve is opened, one of the disks is subjected to the full chamber pressure and ruptures, in turn overloading and rupturing the second burst disk.

			_Mechanically Induced Failure_
			Alternatively, the structural integrity of a single burst disk may be compromised, as by a broad head on a pneumatic ram or a resistive heating element embedded in the burst disk.

			By damaging the burst disk, the bursting pressure of the disk decreases, until the pressure in the chamber is sufficient to destroy it.
