Ignition and Combustion of Solid Propellants

1961
Abstract : A model for the ignition response of solid propellants is presented, which predicts ignition behavior with respect to pressure and surface heat flux in qualitative agreement with experimental measurements. Surface regression is treated and a steady-state burning model is employed, which assumes equlibrium vaporization at the surface and a ...

Adiabatic pyrolysis of solid propellants

35th Aerospace Sciences Meeting and Exhibit, 1997
Several one-step, irreversible, zero-order pyrolysis models (Arrhcnius, KTSS, and Merzhanov Dubovitskii high activation energy pyrolysis), commonly used to study adiabatic burning of energetic materials with arbitrary pressure and initial temperature, are revisited.

Solid propellent rheology

Rheologica Acta, 1969
The rheological behaviour of plastic propellent in rocket motor situations is simulated in an experimental technique. In this a differential gas pressure is applied across a plug of propellent in a rigid tube so as to deform it in an approximately telescopic shear fashion. Preliminary results are given and discussed.

Ignition of solid propellants

Journal of Applied Mechanics and Technical Physics, 1968
At present, the study of solid-propellant ignition is of particular interest owing to the adoption of hybrid motors [1–3]. The status of experimental and theoretical research in this field can be evaluated on the basis of the rather extensive survey of American papers in [2].

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 ...

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),

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 ...
