Nitramine smokeless propellant research [PDF]

A transient ballistics and combustion model is derived to represent the closed vessel experiment that is widely used to characterize propellants. A computer program is developed to solve the time-dependent equations, and is applied to explain aspects of ...

Ultrasonically Accelerated Nitration of Hydroxyl-Terminated Polybutadiene: Process Efficiency and Product Characterization

Eng
Hydroxyl-terminated polybutadiene (HTPB) is widely studied and the most used prepolymer for the binder system of composite solid propellants. A suitable functionalization of HTPB with energetic groups greatly improves the performance of the propellant ...

Rheology of suspensions with aluminum nano-particles [PDF]

, 2009
Nano-scale aluminum particles are innovative materials increasingly used in energetic formulations. In this contribution, the rheological behavior of suspensions with either paraffin oil or HTPB as the matrix fluid and nano-scale aluminum (ALEX) as the ...

Experimental and simulation study on micro damage of HTPB propellant under multi angle tensile shear loading

Polymer Testing
The damage evolution of composite solid propellants is influenced by the stress state. In order to investigate the in-situ damage evolution mechanism of hydroxyl terminated polybutadiene (HTPB) propellant under tensile shear conditions, computer ...

Nitramine propellants [PDF]

, 1978
Nitramine propellants without a pressure exponent shift in the burning rate curves are prepared by matching the burning rate of a selected nitramine or combination of nitramines within 10% of burning rate of a plasticized active binder so as to smooth ...
