Solid-propellant erosive burning

Journal of Propulsion and Power, 1987
A modeling approach based on experimental verification for the erosive burning of ammonium perchlorate composite propellants is proposed. It retains the idea that erosive burning is due to the penetration of the flow turbulence within the flame height and to the consequent enhancement of the transport coefficients and of the heat flux to the surface ...

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.

Stability of Solid Propellant Combustion

Physical Review Letters, 1994
The stability of a combustion wave is one of the most important problems in combustion theory. The solution of the problem can be essentially simplified if the characteristic scales of the processes governing the combustion are small in comparison with the characteristic dimensions of the problem.

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.

Detonability of Solid Composite Propellants

ARS Journal, 1961
The thin film pla t inum resistance thermometer (heat flux gage) has been successfully applied to measurement of heat fluxes from initiators for solid propellants. Hea t fluxes measured were as high as 1000 Btu/ft-sec from hot, particleladen reaction products of pyrotechnic igniters.

Solid propellant sandwich deflagration analysis

12th Aerospace Sciences Meeting, 1974
A theoretical solution has been obtained for the shape of a deflagrating ammonium perchlorate surface when it is adjacent to an inert, pyrolysing, dry binder. The eigenvalue, the regression rate, is shown to be independent of binder type and very close to the burn rate of pure AP, as has been experimentally observed.

Solid Propellant Rocket Motors

The Journal of the Royal Aeronautical Society, 1961
A solid propellant rocket motor consists essentially of a propellant charge in a container fitted with an expansion nozzle and igniter. Since, before a rocket motor can be designed, it is necessary to have some knowledge of the properties of the propellant to be used, a description will first be given of the propellants which are currently available.
