Generation Characterization and Aerospace Applications of Torch Plasmas

摘要

This basic research effort addressed the physical issues related to the generation of atmospheric pressure plasmas and to the use of 'Torch Plasmas' for aerospace applications. The most significant accomplishment has been the development of a plasma torch into an ignition aide for use in scramjet engines. It was shown that such a torch can deliver sufficient heat to cold, liquid JP-7 fuel injected into a Mach-2 crossflow (having a static temperature of (caret) 500 K) to reduce the ignition delay time and to increase the rate of combustion and, thus, to initiate main-duct combustion.
