Abstract
A gaseous oxygen resonance igniter includes a body with a first inlet for gaseous oxygen incorporating a supersonic nozzle. An outlet from the body incorporates an orifice of predetermined size to maintain a desired pressure in the body. An aperture in the body opposite the first inlet provides a port to a ceramic resonance cavity. A ceramic bleed disc is engaged at a second end of the resonance cavity. An end cap incorporates a plenum adapted to receive high temperature oxygen flow from the resonance cavity through the bleed disc. An exhaust port is connected to the plenum for the high temperature oxygen which flows to a mixing chamber which introduces pilot fuel for ignition as a combustion initiation torch.
