[ 1 ] - اثر مقدار دیمریل دیایزوسیانات بر رفتاررئولوژیکی و خواص مکانیکی یک پیشرانه جامد مرکب بر پایه HTPB
Several parameters affecting the rheological and mechanical properties of solid composite propellants. Among them, the molar ratio of isocyanate (NCO) to hydroxyl (OH) groups (R value) is one of the important factors. In this research, the effects of changing in the weight ratio of dimeryl diisocyanate (DDI) curing agent related to hydroxyl terminated polybutadiene investigated on different pr...
[ 2 ] - بهینهسازی رئولوژیکی یک نمونه پیشرانه جامد مرکب با افزایش مالئیک انیدرید
Viscosity is one of the important parameters in design and production of composite solid propellants. Propellants with low end of mix (EoM) viscosity and longer pot-life have suitable condition for casting process. Several factors control the rheology behavior of propellants. In some cases, it may be necessary to apply some additives in order to optimize the rheology of the formulation. In this...
[ 3 ] - اثر نانو ذرات میلهایشکل اکسید آهن هماتیت بر خواص یک پیشرانه جامد مرکب
Iron oxide as a burning rate catalyst commonly used in many of solid composite propellants. As the particle size of this component decreased, the final properties of the propellant change. In this research, effects of using 1 percent by weight of nano hematite iron oxide (α-Fe2O3) investigated on properties of an HTPB/AP/Al formulation and compared with the same propellant containing micronized...
