Combustion Instabilities in Liquid-Fuelled Propulsion Systems: Conference Proceedings of the Propulsion and Energetics Panel (72nd) B specialists Meeting Held in Bath (England) on 6-7 October 1988
Abstract
Although combustion instabilities have been troublesome for more than four decades, many problems remain unsolved. Recent work, particularly related to ramjets, and potential applications of liquid rocket engines in vehicles now being studied, made this meeting very timely. The presence of pressure oscillations in afterburners continues to cause concern in the development of new engines. There are fundamental reasons, primarily the high densities of energy release, that combustion chambers in modern propulsion systems are susceptible to combustion instabilities. There possible occurrence must be anticipated in any new design. As performance is pushed to higher levels, so also is the likelihood of pressure oscillations. It is therefore important to sustain continuing research on the subject and to ensue rapid flow of information to the engine designers and manufacturers. It appears reasonable that a subsequent meeting having essentially the same purposes as 72B could fruitfully be held in 3-5 years.
