Rheological Properties of Composite Polymer Liner Based on Hydroxyl‐ Terminated Polybutadiene [PDF]
Journal of Aerospace Technology and Management, 2020 An experimental study to determine the dependence of the viscosity and shear stress of hydroxyl-terminated polybutadiene (HTPB) and dimeryl diisocyanate (DDI) liner on curing time is presented. Viscosity and shear-stress were measured by HAAKE RheoStress

A Model for Igniter Mass Flow Rate History Evaluation for Solid Rocket Motors
International Journal of Aerospace Engineering, 2019 This paper describes a zero-dimensional model for evaluating the mass flow rate history of a solid rocket motor igniter. Based on the results of an igniter-firing experiment, in which the igniter is the only source of combustion gas and no propellant is ...
