The Ignition of Liquid Propellants by Acoustic Cavitation

Abstract

The subject of this report is the ignition of a liquid monopropellant by acoustic cavitation. An experimental result of this study was the successful preliminary ignition of the monopropellant by an acoustic horn-transducer assembly. Upon examination of these ignition results, it was postulated that the reaction initiated by the acoustic device would definitely result in combustion of the monopropellant under proper pressure conditions. The proceedings of the experiment is described. The writer concluded: 1. The ignition of liquid monopropellant is possible using acoustic techniques under proper conditions; 2. A value for the minimum energy density necessary to initiate the combustion sequence of the liquid monopropellant has been obtained; 3. The acoustic cavitation ignition technique is a precise, simply, and efficient method, however writer suggests more experiment for further development.
