Introduction to Velocity Coupling in Solid Propellant Rockets.

摘要

This report is a review of the principles of velocity coupling as a mechanism for sustaining pressure oscillations in solid propellant rockets. It is intended as an introduction to the fundamentals of the subject, including current analysis of linear and nonlinear acoustics. Some results are given for the influence of rectification when there is no threshold velocity. As an example, a simplified analysis is given for a T-burner having lateral grains for measuring velocity couplings.
