TLDR
In this article, the authors proposed a simplified theory of burning rate suitable for composite solid propellants, and evaluated the burning rates and related characteristics for two specific ammonium perchlorate-based solid powders, one aluminized and the other non-aluminized.Abstract:
One of the principal parameters associated with a solid propellant is its linear burning rate. Many attempts have been made in the past to determine theoretically the burning rates of solid propellants by the use of appropriate combustion models. The object of the present paper is to propose a simplified theory of burning rate suitable for composite solid propellants. While the paper follows basically the scheme suggested for this purpose by Beckstead, Derr and Price using multiple flamelets, certain simplifying assumptions have been introduced with a view to make the model easier to operate. An attempt is also made in the paper to extend it to the case of aluminized solid propellants as well on the basis of a specific hypothesis regarding the role of aluminium. The relevant transcendental equations of combustion were solved on a digital computer. The burning rates and related characteristics were evaluated by this technique for two specific ammonium perchlorate-based solid propellants, one aluminized and the other non-aluminized, and the results obtained agree reasonably with the reported experimental trends.read more

TL;DR: Frazier et al. as discussed by the authors used a model based on the classic Beckstead-Derr-Price (BDP) and Cohen-Strand models to predict measured burning rates for baseline propellants without additives over a range of 500 − 3000 psi within 10%.

A Model of Composite Propellant Combustion Including Surface Heterogeneity and Heat Generation
TL;DR: In this paper, the surface heterogeneity of a composite propellant is incorporated in a model of the propellant combustion process, explicitly including the oxidizer particle size distribution, and expressions for the mean, one-dimensional, propellant surface and flame temperatures are derived assuming planar regions of heat generation.

Temperature sensitivity of propellant burning rates
TL;DR: In this paper, the effect of the initial temperature on the burning rate of the JANNAF standard composite propellant was investigated using four combustion models: the granular diffusion flame model based on the uniformly distributed heat release (KTSS) model, the Beckstead, Derr, and Price (BDP) multiple flame model, a modified BDP model, and the petite ensemble model.
