Simulation of Composite Propellant Aging

Polymer-Plastics Technology and Engineering, 1993
Abstract Inert polyurethane (PU)-glass elastomeric composites were fabricated to simulate the mechanical behavior of composite propellant systems. A polyether PU system was used in conjunction with 60 wt%, 20 μm glass beads. The mechanical and interfacial properties of model systems were evaluated as a function of time and temperature, using Instron ...

Review of composite propellant burn rate modeling

17th Aerospace Sciences Meeting, 1979
Steady-state combustion modeling of composite solid propellants is discussed with emphasis on the Beckstead-Derr-Price (BDP) model. The BDP model and some revisions are considered with respect to the analysis of monomodal ammonium perchlorate/inert binder propellants: topics examined include continuity relations, surface area relations, characteristic ...

Depressurization extinguishment of composite solid propellants - Influence of composition and catalysts

8th Joint Propulsion Specialist Conference, 1972
Abstract : The experimental results at 100 bar initial pressure emphasize the importance of the condensed phase properties on the depressurization extinguishment. In all cases of alteration of these properties by the change of binder, the particle size distribution, or the addition of Aluminum the critical depressurization rate for extinguishment was ...

Erosive burning of composite solid propellants

Combustion and Flame, 1966
A model is proposed for erosive burning of ammonium perchlorate composite wolid propellants. It is assumed that combustion takes place in the turbulent boundary layer and that the turbulent flame consists of distorted ‘flamelets’ but otherwise retains on a molecular scale the characteristics of a laminar flame.
