Combustion Response of Ammonium Perchlorate

چکیده
Amodi ed Price–Boggs–Derr model is applied to compute the linear and nonlinear combustion response properties of monopropellant ammonium perchlorate (AP). The kinetics constants were changed to achieve good agreement with response function data as well as with steady-state data. The numerical method was rst validated with the classical theory. Computations using the Levine and Culick boundary condition in the limit of small perturbationswere compared with the exact mathematical solution for linear response, and the effect of perturbation amplitudewas explored. Then, using the APmodel for the boundary condition, various linear and nonlinear computations were performed. Supplemental mathematical analyses relate the AP model to the basic two parameters of the classical theory and show the key factors determining the nature of the combustion response.

Analytical Solution for Pressure-Coupled Combustion Response Functions of Composite Solid Propellants
This paper extends the classical analytical solution for small perturbation analysis of the pressure-coupled response of a homogeneous propellant to any two-component composite propellant. The solution obtained is general and can be used with any particular model for propellant combustion. As an example, the Cohen and Strand ammoniumperchlorate propellantmodel for a single ammoniumperchlorate p...

متن کاملThe effects of additives on the combustion characteristics of aluminum powder in steam
To develop the combustion characteristics of aluminum powder in steam, the ignition and combustion process of aluminum powder with different additives (KBH4, ammonium perchlorate (AP) and NaCl) addition at different levels were studied using a transparent pipe furnace. The temperature variation of these samples was measured using a thermocouple, and a high-speed camera was used to record combus...
