Solid Propellant Combustion Instability: Oscillatory Burning of Solid Rocket Propellants

A review of calculations for unsteady burning of a solid propellant.

“…The 52. A formula for q's+ was found simply by linearizing the steady-state form of the energy matching condition.…”

Research on Solid Propellant Combustion Instability

“…Another set of experiments concerned the spectral distribution of the flame zone. Full details of emitters, experimental layout, etc., are given in (6). The significant feature of the experiments was that CN radiation (the 3883 Angstrom band) was not confined to the surface region but extended, in some cases, over several millimeters from the surface.…”

“…Further discussion of the points mentioned above can be found in the report by W. Waesche and M. Summerfield "Oscillatory Burning of Solid Rocket Propellants"' (6). In addition, this report contains a discussion of the many processes involved in the problem of comburtion instability, a review of the theoretical and experimental treatments of several of these processes, and an analysis of several candidate experiments for the investigation of one of these processes, namely, the coupling of a pressure oscillation with a surface flame zone.…”

“…As seen in Figure 4, a Fastax camera was used for cinematography, while streak photography was also used to detect the waves. Full details are given in the previously-mentioned report (6), which also describes tie operating characteristics and variables of the T-burner as a source of oscillating pressure.…”
