SYREN - Acoustic Resonance Igniter

ORBITEC proposes to continue the development of the SYREN Igniter to meet the performance goals of the next generation of liquid hydrocarbon boost and upper stage rocket engines. This effort will advance the technical readiness level of an innovative family of igniters for rocket combustion devices. These igniters will exceed current reliability standards, reduce ignition system overhead, and provide system-level benefits by minimizing weight, decreasing power requirements, and improving serviceability. This highly-reliable, non-toxic ignition system is designed for use with LOX-hydrocarbon rocket engines, as well as other rocket engine cycle components such as preburners and gas generators. During Phase II, the SYREN igniters will be used to ignite several LOX-HC combustion devices ranging in thrust levels from 100 lbf to 50k lbf. BENEFIT: The end product of this research and development program will have application for a range of military and commercial launch systems, satellite propulsion and station-keeping, as well as potential aerial warfare and tactical surface applications. Additionally, the SYREN technology could readily be developed and deployed as small thrusters for micro- and nano-satellite propulsion, or DACS thrusters on larger spacecraft. The acoustic resonance igniter also has potential monopropellant applications. NASA may also find use for this technology in the support of reusable launch vehicles and upper stages as well as for in-space propulsion where the simplicity and reliability of the acoustic igniter offers the greatest benefits. Commercial satellite providers would also find this technology attractive for reducing the propulsion system weight and improving performance. The potential market for acoustic igniters and related technologies could be quite large. Application focus areas include military, space, and industrial users. During the Phase II activities, ORBITEC personnel will work to develop a detailed commercialization plan that involves the major propulsion companies. Three specific commercial avenues are anticipated during Phase II: 1) providing acoustic igniters for use with a Government sponsored hydrocarbon thrust chamber and ox-rich preburner; 2) developing this technology for use with ORBITEC’s LOX-hydrocarbon rocket engines; 3) pairing the SYREN with a cryogenic RCS motor.
