A Feasibility Study of Command Control of Solid Propellant Burning Rate
Abstract
Analytical studies of twenty methods of command control of burning rate were performed to help establish which methods are most likely to be effective. Any method which offers a plus or minus 5% or greater throttle ability is of interest. Since the study was not directed at a particular application, problems of implementation were not considered in detail. The approaches which received the greatest attention include: thermal radiation by injected particles and inserted intensifiers, acoustic energy, penetration of thermal wave by back flow of combustion gased into either perforated propellants or embedded porous elements, injection of burning rate catalysts, rammed propellant surfaces, and resistive heating. Other methods which were surveyed include: partial quenching, heating through vibration, induced unstable burning, dielectric heating, resistive wire networks, electrical and electromagnetic effects on flames and ingredient decomposition, acceleration forces, and utilization of photochemical processes.
