[ 1 ] - ارزیابی اثر پارامترهای مختلف بر روی پدیده کوهانی شدن در پیشرانه-های جامد مرکب
By comparing the empirical and predicted performance diagrams of the composite solid propellants, it appears that there is a discrepancy between these two graphs .This deviation has been attributed to spatial burning rate variation which is related to burning rate fluctuation or hump effect. The most important reasons for this spatial burning rate variation are casting process. In order to appr...
[ 2 ] - مروری بر پیشرانه های سبز بر پایه آلومینیوم-آب
The reaction between fine aluminum particles and water over the past fifty years, due to high energy generation and green products is in consideration. But all aluminum particles have an inactive oxidative layer and in case of Nano-Al this layer has high ratio of particles. So, efficiency of hydrogen produced by the reaction between water and aluminum is less than the theoretical value. There a...
[ 3 ] - اثر شتاب چرخشی بر روی بالستیک داخلی موتور پیشرانه های جامد
Recent studies in solid composite propellants indicate that acceleration field cause to increase in burning rate. Relation between acceleration field and burning rate of propellant have an important effect on missile systems ballistic, especially on perforated grain missiles. If these effects has neglected in design phase, the pressure-time profile shifted out of acceptable rage and result in i...
