TLDR
In this article, a model was proposed which can be applied to both compression and depressurization that takes into account the unsteadiness of the gas phase, and the energy liberation at the surface of the propellant was maintained constant.About:

Experimental and theoretical extinction of solid rocket propellants by fast depressurization
R. Dondè,G. Riva,L.T. De Luca +2 more
TL;DR: In this article, the extinction boundary in terms of maximum depressurization rate vs initial pressure can be constructed by go/no-go testing for a given final pressure, and a good agreement was found between analytical, numerical, and experimental results.

H. K. Suhas,T. K. Bose +1 more
TL;DR: In this article, the authors carried out parametric analysis of unsteady combustion of composite propellants taking into account all the experimentally observed phenomena, and the predicted dynamic burning rates were compared with the available experimental results.

A review of calculations for unsteady burning of a solid propellant.
TL;DR: A = E(l T^ admittance function, Eq. (1) sensitivity of gas phase to pressure changes specific heats of solid and gas activation energy for surface reaction E = ES/RTS enthalpy latent heat for surface reactions; Hp > 0 for exothermic s_urface reaction H = Hp/cT average mass flux fluctuation of mass flux at the surface index in the linear burning rate law, r = ap index in surface pyrolysis law as discussed by the authors.

A Simplified Model of Unstable Burning in Solid Propellants
M. Richard Denison,Eric Baum +1 more
TL;DR: An analysis of the surface temperature and hence mass flux, response of a solid propellant to a disturbance in gas pressure has been developed in this article, where stability conditions are obtained in terms of a few dimensionless parameters which depend upon the steady state conditions.

Nonsteady burning phenomena of solid propellants - theory and experiments
TL;DR: In this paper, the non-steady burning of solid propellants was investigated both theoretically and experimentally, with attention to combustion instability, transient burning during motor ignition, and extinction by depressurization.
Journal ArticleDOI
Theory of dynamic extinguishment of solid propellants with special reference to nonsteady heat feedback law
TL;DR: In this article, two methods for predicting instantaneous burning rates are described and compared: theories based on models of the flame and the Zeldovich-Novozhilov method which uses the steady state burning rate data as functions of pressure p and initial temperature TO to deduce the appropriate nonsteady law for the heat feedback rate from the flame.
