Solid Rocket Propellants: Science and Technology Challenges

Abstract

Propellants contain considerable chemical energy that can be used in rocket propulsion. Bringing together information on both the theoretical and practical aspects of solid rocket propellants for the first time, this book will find a unique place on the readers' shelf providing the overall picture of solid rocket propulsion technology. Aimed at students, engineers and researchers in the area, the authors have applied their wealth of knowledge regarding formulation, processing and evaluation to provide an up to date and clear text on the subject.

Energetic Polymer Possessing Furazan, 1,2,3-Triazole, and Nitramine Subunits

“…An analytical sample was prepared by double precipitation from the DMSO solution with methanol, after which the precipitate was filtered, washed with methanol, and dried in vacuum for a day at 60 • C, which gave a colorless powder (89%). 1 1,5 ), 4.81 (s, 2H, OCH 2 -Het 1,4 ), 5.19 (s, 2H, N(NO) 2 CH 2 OCH 2 -Het 1,5 ), 5.24 (s, 2H, N(NO) 2 CH 2 OCH 2 -Het 1,4 ), 5.93 (s, 2H, Het 1,5 -CH 2 -furazan-CH 2 -Het 1,5 ), 5.96 (s, 2H, Het 1,4 -CH 2 -furazan-CH 2 -Het 1,5 ), 5.97 (s, 2H, Het 1,4 -CH 2 -furazan-CH 2 -Het 1,5 ), 6.01 (s, 2H, Het 1,4 -CH 2 -furazan-CH 2 -Het 1,4 ), 7.80 (s, 1H, Het 1,5 -CH), 8.22 (s, 1H, (Het 1,4 -CH)-CH 2furazan-CH 2 -(Het 1,5 -CH)), 8.24 (s, 1H, Het 1,4 -CH). 13…”

“…4 Onset temperature of mass loss. 5 Mass loss during decomposition. 6 Due to the evaporation of the compound, it was not possible to obtain values for the enthalpy of decomposition.…”

“…For instance, a multicomponent system of solid composite propellants (SCPs) usually includes an oxidizer (50-80%, oxygen-rich inorganic and/or organic compounds), combustible (up to 25%, high-calorific metals or their alloys, metal hydrides, boron and its derivatives, high nitrogen compounds, etc. ), binder (10-25%, plasticized polymers), catalysts, and processing aids [1][2][3][4][5][6][7]. All these components, complementing each other, should provide the required effect-the development of the maximum thrust and the maximum increase in the speed of the aircraft in the process of propellant burning, ensuring the delivery of the certain mass to the maximum possible distance.…”

The thermal decomposition mechanism of RDX/AP composites: ab initio neural network MD simulations

“…It is usually composed of fuels, an oxidizers, binders, catalysts, and other materials. [1][2][3][4] 1,3,5-Trinitro-1,3,5-triazine (RDX) is a well-known energetic material with exceptional performance, which is commonly used in explosives and solid propellants. [5][6][7] Ammonium perchlorate (AP), as a versatile oxidizer, 8 has been widely applied to various solid propellants 9,10 due to its high effective oxygen content, good physical and chemical stability, and excellent compatibility with other propellant components.…”
