An acoustic igniter eliminates the need to use electrical energy to drive spark systems to initiate combustion in liquid-propellant rockets. It does not involve the use of catalysts (which have a limited life), it does not exhibit typical wear and tear as seen in spark and catalytic igniters, and it is simple in design with no moving parts. Orion's proposed Acoustic Igniter is expected to offer a long-life, highly reliable ignition system that does not require high-voltage electrical connections. It is less complex to operate and simpler than a traditional ignition system.
