ABSTRACT:
A liquid propellant is burned in the bulk mode and in pulses to produce high combustion pressures with large power outputs. The pulsed high pressure liquid propellant combustion is also used for producing sound waves for underwater seismic exploration. The high combustion pressures produced by burning the liquid propellant in the bulk mode and in pulses may be used to overcome high back pressures such as those existing at deep drilling depths and in deep ocean depths.
