AN ANALYSIS OF AXIAL ACOUSTIC WAVES IN A COLD-FLOW ROCKET

Abstract

The presence of waves in a rocket chamber depends on the relative importance of energy supplied by interaction with the combustion processes and energy lost through dissipative processes. As an aid to assessing the latter, the cold-flow rocket appears to be a promising tool for both research and development. Combustion is absent and acoustic waves are excited mechanically in a chamber through which a steady flow is maintained. The analysis presented here is intended to serve as a basis for interpreting such measurements. Only the case of axial, or longitudinal waves is treated, and results show mainly how the losses at the exhaust end of the chamber may be inferred from measurements of the transient response and the frequency response of a chamber.
