Webbwere observed in free-standing propellant grains of special purpose motors processed with pvc-plastisol based composite propellant. The shape and orientation could be traced to the high temperature physical curing process, casting technique, viscosity of slurry during casting and the casting set-up configuration.

Webb6 juli 2024 · The star-shaped propellant grain design parameter like burn perimeter by using non-dimensional equations is evaluated. A MATLAB code is written in order to plot the non-dimensional burn-perimeter (S/l) versus burnt distance (y + f)/l for star-shaped propellant grain having star point, n = 6 for = 65-75. WebbThree HTPB-based rocket propellant formulations containing ammonium perchlorate and aluminum particles, with different aluminum content and particle size, have been manufactured. The study has focused on the change of mechanical properties with aging time by using dynamic mechanical analysis (DMA). Therefore, propellant formulations …
Webb16 aug. 2024 · Small angle neutron scattering (SANS) with contrast variation was used to characterize the fractal behavior and embedded porosity of micro/nano-sized 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) crystallites, gauging the effects of particle sizes on the microstructural features. Scattering results reveal that the external surface of micro … Webb25 juni 2014 · At $45 dollars including tax, you can't go wrong with this setup. It has TONS of rocks of all shapes and sizes. This gives you the opportunity to aquascape until your hearts content. Sizes that were large were definitely heavy and sizes that were medium to small were of decent size and weight. They are very true and porous as well.
WebbThe geometry and size of the particles in the sprays were analyzed by two shape descriptors: (i) the Feret diameter, also known as maximum caliper, which indicates the maximum distance between two points in the boundary of a particle, thus representing the diameter of a circular particle or the length of a ligament; and (ii) Circularity, which …
