Mechanical properties of HTPB composite propellants in the initial period of service life [PDF]
Scientific Technical Review, 2014 Uniaxial tensile tests of different composite solid rocket propellant compositions, based on hydroxyl-terminated polybutadiene (HTPB), have shown that mechanical properties extensively change after curing, up to 100% of their initial values, during the ...

PARAMETRIC STUDY ON TAPER-ENDED TUBULAR SOLID PROPELLANT GRAINS [PDF]
The International Conference on Applied Mechanics and Mechanical Engineering, 2018 The design of the solid propellant grain is a decisive aspect of the solid propellant rocket motor performance. Tubular grain design is a favorable design since it produces a high neutral (time-invariable) thrust-time profile. However, neutrality of tubular grains deteriorates as the aspect ratio of the grain deviates from an optimum value that is ...
