Abstract

An ignition system for a combustion device utilizes an oscillating pressure force in a resonance system to generate thermal energy within a resonance driven glow plug. The resonance driven glow plug stores the thermal energy for transfer to ignitable propellant combinations within a torch assembly and thus within the combustion chamber.

Description

BACKGROUND OF THE INVENTION

[0001] The present invention relates to an igniter system for ignition of a rocket engine or other combustion device for propulsion, power, or industrial processing applications, and more particularly to a method which utilizes pressure energy to generate thermal energy which is transferred into a glow plug body to store the energy for transfer to ignitable propellant combinations in a torch assembly.

[0002] Various conventional ignition systems have been used for ignition of an ignitable propellant mixture in a combustion chamber of a rocket engine. Some ignition systems employ a spark induced by an electrical current. Other ignition systems employ glow plugs which are electrically heated. These conventional systems, although effective, tend to be relatively complex and heavy as each system requires electrical cabling, connectors, power, and control systems.

[0003] Accordingly, it is desirable to provide an uncomplicated, lightweight ignition system which is h...
