Nanomaterials as modifier for composite solid propellants

Nano-Structures & Nano-Objects, 2019
Propellants are the major source of chemical energy in space vehicles and missiles. The AP (Ammonium perchlorate), AN (Ammonium nitrate), RDX (Hexahydro-1, 3, 5-trinitri-1, 3, 5-triazine) and HMX (Octahydro-1, 3, 5, 7-tetranitro-1, 3, 5, 7- tetrazocine),

Review of solid-propellant ignition studies

16th Joint Propulsion Conference, 1980
AN extensive review of the literature on solid-propell ant ignition was made to establish the state-of-the-art. Various ignition theories, experimental measurements, and ignition criteria were critically examined. The review was summarized in easy-to-read tabular form to facilitate comparison between various studies. The effects of important parameters

Acoustic Resonance in Solid Propellant Rockets

Journal of Applied Physics, 1960
Attention is drawn to the fact that the solid propellant must, in general, be considered as one of the acoustic media in a rocket motor. The viscoelastic properties of the solid along with those of the burned gases determine the characteristic modes of the system corresponding to the particular boundary conditions imposed on these media by the metal ...

A mesoscopic damage model of solid propellants under thermo-mechanical coupling loads

Polymer testing, 2019
Solid propellants are well-studied particle reinforced polymer composite materials that are usually subject to complex stress actions. However, their destructive performances under thermo-mechanical coupling loads have been rarely studied. In the present

Virtual prototyping of solid propellant rockets

Computing in Science & Engineering, 2000
Researchers seek a detailed, whole-system simulation of solid propellant rockets under normal and abnormal operating conditions. A virtual prototyping tool for solid propellant rocket motors based on first principles models of rocket components and their dynamic interactions meets this goal. Given a design specification (geometry, materials, and so on),

Ignition and combustion behavior of mechanically activated Al–Mg particles in composite solid propellants

Combustion and Flame, 2018
Metallized propellants typically produce large agglomerates that result in two-phase flow losses. Tailoring composite metal fuel particles can improve ignition and combustion characteristics while reducing product droplet sizes.

Nano-composites for rocket solid propellants

Composites Science and Technology, 2005
Aim of this work is the study of different components (binder and aluminum powders) of solid propellants used for rocket propulsion to improve ballistic performance. New propellant formulations have been tested and characterised. Combustion residues were collected by a proprietary method and analyzed both from the morphological and chemical point of ...
