Acoustic Resonance in Solid Propellant Rockets
Journal of Applied Physics, 1960Attention 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 ...

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].

Solid propellants are of two basic types: composites and double base propellants. The latter consist of a backbone of nitrocellulose (guncotton) onto which a quantity of nitroglycerine has been absorbed, resulting in a leathery propellant which can be cast or extruded into desired shapes.

Nano-composites for rocket solid propellants
Composites Science and Technology, 2005Aim 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 ...

Viscoelastic Properties of Solid Propellants and Propellant Binders
1965Abstract : Studies supplementary to the determination of the dynamic shear modulus are reported. The effects of specimen geometry and the magnitude of shear strain on the dynamic modulus of polyurethane propellant AEBA-10 were studied. A method was worked out to correct measurements to the same level of shear strain to allow a direct comparison under ...

Solid Propellants and Astronautics
1955It ist shown that solid propellants can be useful for certain astronautical operations. A critical review of solid propellants and motor systems is presented. It is pointed out that solid propellants compare very favorably with liquid propellants especially for applications in high altitude rockets and in boosters for space aggregates.

Oscillatory burning of solid composite propellants
Symposium (International) on Combustion, 1963Analytical consideration of the interaction of an oscillatory pressure disturbance with the burning zone of a composite propellant leads to the conclusion that acoustic waves induce periodic variations in the ratio of the mass release rates of composite propellant components that give rise to harmonic composition and adiabatic flame temperature ...
